8 1 Component Numbering for T-Class Storage System NOTE: Illustrations in this chapter show sample systems and might not match your configuration. Identifying Storage System Components Figure 1 (page 8) and Figure 2 (page 9) identify the major components of the T400 Storage System in a 2M (40U) HP 3PAR cabinet. Figure 1 T400 Front View 8 Component Numbering for T-Class Storage System

9 Figure 2 T400 Rear View Service Processor Placement The Service Processor (SP) is located at the bottom of the cabinet and is designed to support all actions required for maintenance of the storage system, providing real-time, automated monitoring. The SP also supports remote access to diagnose and resolve potential problems. The SP is usually installed directly above the PDUs and below the battery tray (Figure 3 (page 10)) and is powered internally by the storage system. The SP does not require an external power connection. Service Processor Placement 9

10 Figure 3 Placement of the Service Processor NOTE: In the T800, the SP is located above the backplane, below the lowest drive chassis but above the upper battery tray. Figure 5 (page 12) illustrates SP placement for the T800. When a cabinet does not include a SP, a filler panel covers the area of the cabinet that the SP normally occupies. Understanding Component Numbering Because of the large number of potential configurations, we have standardized component placement and internal cabling to simplify installation and maintenance. For this reason, system components are placed in the cabinet according to the principles outlined in this section and numbered according to their order and location in the cabinet. NOTE: For information about standardized cabling, see the HP 3PAR T-Class Storage System Installation and Deinstallation Guide. Cabinet Numbering The T-Class Storage System 2M (40U) cabinet is an EIA-standard rack that accepts storage system components. Numbers for chassis bays are assigned: beginning with 0. from top to bottom. Figure 4 (page 11) illustrates numbering of chassis bays in T-Class cabinet. 10 Component Numbering for T-Class Storage System

11 Figure 4 Numbering of Chassis Bays in the Cabinet A storage system can be housed in a single cabinet or multiple cabinets. When multiple cabinets are required, the first cabinet (the controller node cabinet ) holds the storage system backplane populated with controller nodes. Any additional cabinets, or drive chassis cabinets, hold the additional drive chassis that do not fit into the controller node cabinet. Table 2 (page 11) describes the pattern for cabinet numbering in multi-cabinet storage systems and for operating sites with multiple systems: Table 2 Cabinet Numbering Cabinet Controller node cabinet Drive chassis cabinets connecting to the first node cabinet Number C00 C01, C02, C03... C09 Figure 5 (page 12) shows the location of system components for the T400 and T800 controller node cabinets. Figure 6 (page 13) shows the location of system components for drive chassis cabinets. Understanding Component Numbering 11

12 Figure 5 Controller Node Cabinet Component Layout 12 Component Numbering for T-Class Storage System

13 Figure 6 Drive Chassis Cabinet Component Layout PDU Numbering For each cabinet, the four Power Distribution Units (PDUs) occupy the lowest chassis bay in the cabinet. Numbers for PDUs are assigned: beginning with 0. from top to bottom. Figure 7 (page 13) illustrates the four PDUs at the bottom of a T-Class cabinet. Figure 7 Numbering of PDUs Understanding Component Numbering 13

14 NOTE: In the T800, PDUs are positioned back-to-back so that they only take up 2U of space at the bottom of the cabinet rather than the standard 4U of space. PDUs are accessible from both the front and the rear of the storage system. Controller Node Cabinet Component Layout (page 12) illustrates PDU placement for the T800. Each PDU has two power banks, each with a separate circuit breaker, to be used exclusively for storage system components (Figure 8 (page 39)). Figure 8 Power Banks in the PDU WARNING! To avoid possible injury, damage to storage system equipment, and potential loss of data, do not use the surplus power outlets in the storage system PDUs. Never use outlets in the PDUs to power components that do not belong to the storage system or to power storage system components that reside in other cabinets. NOTE: For more information on PDUs and storage system configurations, see the T-Class Storage System Installation and Deinstallation Guide. Battery Backup Unit Numbering The controller node cabinet includes one or two battery trays that hold the battery backup units (BBU). The BBUs supply enough power to write the cache memory to the IDE drive inside the nodes in the event of a power failure. One battery per controller node is required for all storage system configurations. BBU placement and numbering schemes vary according to the type of components used in the system. There is always a battery tray located directly below the backplane. When a second battery tray is required, as is the case with storage systems that have six or eight controller nodes, a second battery tray rests immediately above the backplane. Storage systems use Magnetek BBUs. Each battery unit contains two independently-switched batteries, labeled battery a and battery b (Figure 9 (page 14)). Figure 9 Battery Backup Unit 14 Component Numbering for T-Class Storage System

15 A battery tray can hold a maximum of four BBUs. The number of BBUs and battery trays in a system depends on the number of controller nodes installed (Table 3 (page 15)). Table 3 Number of BBUs and Battery Tray Placement by Storage System Backplane and Number of Controller Nodes Backplane Nodes BBU Battery Trays Tray Placement T Below backplane Below backplane T Below backplane Below backplane Below backplane (1) Above backplane (1) Below backplane (1) Above backplane (1) Magnetek Battery Backup Units Magnetek BBUs have batteries that sit vertically, with battery A above battery B. (Figure 10 (page 15)). Figure 10 Magnetek BBUs When facing the rear of the storage system, Magnetek BBUs are numbered from right to left, 0 through 3. When two battery trays are present, the upper tray is numbered 0 and the lower tray is numbered 1 (Figure 11 (page 16)). Understanding Component Numbering 15

16 Figure 11 Magnetek BBU Numbering Scheme Controller Node Numbering The T-Class Storage System contain two, four, six, or eight controller nodes per system and only use T-Class controller nodes. Controller nodes are loaded into the backplane enclosure from bottom to top. Therefore, for the T800 with only two controller nodes installed, those controller nodes would occupy the lowest 4U of the backplane and would be numbered, node 6 and node 7. The other bays in the backplane enclosure would be protected with filler panels that block insertion of other components. A controller node takes on the number of the bay that it occupies in the backplane, as shown in Figure 12 (page 17). 16 Component Numbering for T-Class Storage System

17 Figure 12 Numbering of Controller Nodes As shown in Figure 13 (page 18), a controller node contains six PCI slots. These slots accept PCI adapters such as dual-port Fibre Channel adapters, iscsi adapters, and Ethernet adapters. The controller node also has a management Ethernet port (E0) and a maintenance port (C1). Understanding Component Numbering 17

18 Figure 13 Numbering for Dual-Port Fibre Channel Adapters in the Controller Node PCI Slots Each Fibre Channel adapter in a PCI slot has four ports. Each iscsi adapter in a PCI slot has two or four ports. PCI adapters assume the numbers of the PCI slots they occupy. In dual-port adapters, ports are labeled port 1 and 2, from top to bottom. In quad-port Fibre Channel adapters, the ports are numbered port 1 4, from top to bottom. Inside the controller node are control cache DIMMs and data cache DIMMs. Control cache DIMMs are located in control cache slots 0 and 1 (Figure 14 (page 19)). Data cache DIMMs are located on data cache riser cards (Figure 14 (page 19)). 18 Component Numbering for T-Class Storage System

19 Figure 14 Control Cache and Data Cache DIMMs in a T-Class Controller Node Numbers for controller nodes and their components are assigned in the order indicated in Table 4 (page 19).

A drive chassis houses two drive cages where each contains five drive bays. Each drive bay can accommodate a single drive magazine holding four disks for a total of 20 disks per drive cage and 40 disks per drive chassis. Numbers for drive chassis are assigned beginning with 0, from bottom to top, beginning with the drive chassis directly above the storage system backplane. Understanding Component Numbering 19

20 Drive chassis are always placed above the storage system backplane enclosure and numbered according to their position in relation to the backplane, as shown in Figure 15 (page 20). Figure 15 Numbering of Drive Chassis NOTE: For systems occupying multiple cabinets, drive chassis numbers continue at the bottom of the next cabinet and progress through the top of the cabinet. Figure 16 (page 21) and Figure 17 (page 21) illustrate individual drive chassis components and how they are numbered. Fibre Channel ports in the FC-AL adapters at the sides of the drive chassis enable connection to the controller nodes. 20 Component Numbering for T-Class Storage System

NOTE: See the systems planning document or HP 3PAR Systems Assurance and Pre-Site Planning Guide for drive magazine allocation instructions specific to your system. Figure 18 Pattern for Loading Initial Drive Magazines into the Drive Chassis 22 Component Numbering for T-Class Storage System

23 NOTE: For further instructions on drive magazine allocation, see the HP 3PAR T-Class Storage System Installation and Deinstallation Guide. Power Supply Numbering Cabinets are divided into upper and lower power domains that contain drive cages or controller nodes and dedicated power supplies. Drive cages and controller nodes depend on these power supplies, located at the rear of the system, to supply power from the PDUs at the bottom of the cabinet. When viewing the cabinet from the rear, the power supplies in each power domain are numbered from 0 to 3, from left to right. Figure 19 (page 23) shows an expansion cabinet. Figure 19 Numbering of Power Supplies within the Power Domains Understanding Component Numbering 23

24 2 Component Numbering for F-Class Storage System NOTE: Illustrations in this chapter show sample systems and might not match your configuration. Identifying Storage System Components Figure 20 (page 24) and Figure 21 (page 25) identify the major components of an F-Class Storage System. Figure 20 F400 Front View 24 Component Numbering for F-Class Storage System

25 Figure 21 F400 Rear View Service Processor Placement The Service Processor (SP) is located at the bottom of the cabinet and is designed to support all actions required for maintenance of the storage system, providing real-time automated monitoring. The SP also supports remote access to diagnose and resolve potential problems. Because the SP is capable of supporting multiple storage systems at the same operating site, not all cabinets contain a SP. However, when present, the SP is usually installed directly above the PDUs and below the drive cage (see Figure 20 (page 24)). The SP is powered internally by the storage system and does not require an external power connection. When a cabinet does not include a SP, a filler panel covers the area of the cabinet that the SP normally occupies. Service Processor Placement 25

26 Understanding Component Numbering Because of the almost unlimited number of potential configurations, there is standardized component placement and internal cabling to simplify installation and maintenance. For this reason, system components are placed in the cabinet according to the principles outlined in this section and numbered according to their order and location in the cabinet. Cabinet Numbering The F-Class Storage System 2M (40U) cabinet is an EIA-standard rack that holds storage system components. Numbers for chassis bays are assigned beginning with 0, from top to bottom. Figure 22 (page 26) illustrates numbering of chassis bays in an HP 3PAR cabinet. Figure 22 Numbering of Chassis Bays in the Cabinet A storage system can be housed in a single cabinet or multiple cabinets. When multiple cabinets are required, the first cabinet (the controller node cabinet ) holds the backplane populated with controller nodes. Any additional cabinets, or drive chassis cabinets, hold the additional drive chassis that do not fit into the controller node cabinet. 26 Component Numbering for F-Class Storage System

27 Table 6 (page 27) describes the pattern for cabinet numbering in multi-cabinet storage systems and for operating sites with multiple systems: Table 6 Cabinet Numbering Cabinet Controller node cabinet Drive chassis cabinets connecting to the first node cabinet Number C00 C01, C02, C03...C09 Figure 23 (page 27) shows the location of controller node and drive chassis components for the storage system cabinet in the F200 and F400. Figure 23 Controller Node and Drive Chassis Component Layout PDU Numbering The four Power Distribution Units (PDUs) occupy the lowest chassis bay in the cabinet. Refer to Figure 22 (page 26) for bay numbering. Numbers for PDUs are assigned : beginning with 0. from top to bottom. Figure 24 (page 28) illustrates the four PDUs at the bottom of an HP 3PAR cabinet. Understanding Component Numbering 27

28 Figure 24 Numbering of PDUs Each PDU has two power banks, each with a separate circuit breaker, to be used exclusively for storage system components (Figure 25 (page 28)). Figure 25 PDU Power Banks WARNING! To avoid possible injury, damage to storage system equipment, and potential loss of data, do not use the surplus power outlets in the storage system PDUs. Never use outlets in the PDUs to power components that do not belong to the storage system or to power storage system components that reside in other cabinets. Controller Node Numbering The F-Class Storage System contains two or four nodes per system. Controller nodes are numbered from top to bottom node 0 and node 1 for a two node system, and node 0, node 1, node 2, node 3 for a four node system. 28 Component Numbering for F-Class Storage System

29 Figure 26 Numbering of Controller Nodes A controller node contains two controller slots and two on-board Ethernet ports. See Figure 27 (page 30) for specific port type assignments. Understanding Component Numbering 29

30 Figure 27 Numbering for Dual-Port Fibre Channel Adapters in the Controller Node PCI Slots Each Fibre Channel adapter in a PCI slot has two or four Fibre Channel ports. Fibre Channel adapters assume the numbers of the PCI slots they occupy. In dual-port adapters, ports are labeled port 1 and port 2, from top to bottom. In quad-port Fibre Channel adapters, the ports are numbered port 1, port 2, port 3, and port 4, horizontally. Inside the controller node are data cache DIMMs and control cache DIMMs. Data cache DIMMs are located in data cache slots 0 through 2. Control cache DIMMs are located on control cache slots 0 and 1 (Figure 28 (page 30)). Figure 28 Control Cache and Data Cache DIMMs in the Controller Node 30 Component Numbering for F-Class Storage System

31 Drive Chassis Numbering Depending on configuration, an F-Class Storage System can include up to 10 drive chassis. A drive chassis houses 16 drive magazines. Drive chassis are first placed sequentially below controller node 1 (controller node 3 in an F400) and then sequentially above controller node 0. Drive chassis are numbered as shown in Figure 29 (page 31). Figure 29 Numbering of Drive Chassis NOTE: For systems occupying multiple cabinets, drive chassis numbers continue at the bottom of the next cabinet and progress through the top of the cabinet. Figure 30 (page 32) and Figure 31 (page 32) illustrate individual drive chassis components and how they are numbered. Fibre Channel ports in the Fibre Channel Arbitrated Loop (FC-AL) at the sides of the drive chassis enable connection to the controller nodes. Understanding Component Numbering 31

The SP also supports remote access to diagnose and resolve potential problems. The SP resides in the lower section of the controller node cabinet and is typically installed directly below the node chassis power supply tray and directly above the DC4 drive chassis (Figure 36 (page 36)). The SP is powered internally by the storage system and does not require an external power connection. Figure 36 Service Processor Placement 36 Component Numbering for HP 3PAR StoreServ Storage

37 Understanding Component Numbering Because of the large number of potential configurations, we have standardized component placement and internal cabling to simplify installation and maintenance. System components are placed in the cabinet according to the principles outlined in this section and numbered according to their order and location in the cabinet. NOTE: For information about standardized cabling, see the HP 3PAR StoreServ Storage Installation and Deinstallation Guide. Cabinet Numbering The 2M cabinet is an EIA-standard rack and houses the storage system components. A storage system can be housed in a single or multiple cabinets. When multiple cabinets are required, the first cabinet (known as the controller node cabinet ) holds the node chassis populated with controller nodes. Any additional cabinets, or drive chassis cabinets, store the additional drive chassis that do not fit into the controller node cabinet. Table 8 (page 37) describes the pattern for cabinet numbering in multi-cabinet storage systems and for operating sites with multiple systems: Table 8 Cabinet Numbering Cabinet Controller node cabinet Drive chassis cabinets connecting to the first node cabinet Number C0 C0, C1, C2-C07 Power Distribution Units Numbering For each cabinet, four Power Distribution Units (PDUs) are mounted vertically on the left side of the rear of the cabinet. Numbers for PDUs are assigned beginning with 0, from bottom to top. Figure 37 (page 38) illustrates the four PDUs in an HP 3PAR cabinet. Understanding Component Numbering 37

38 Figure 37 PDU Numbering Each PDU is equipped with two power banks and separate circuit breakers, used exclusively for storage system components (Figure 8 (page 39)). 38 Component Numbering for HP 3PAR StoreServ Storage

Battery Module Numbering The HP 3PAR StoreServ Storage system include one or two battery compartments that hold up to four battery modules each. The battery compartment is part of the node chassis and adjacent to the node fan compartment. Battery module placement and numbering schemes may vary according to the type of configuration. When facing the front of the storage system, battery modules are numbered 0 through 3 from right to left and directly connected to the correlating controller node. When two battery compartments are present, the battery modules in the upper compartment are numbered 4 through 7 from right to left. Understanding Component Numbering 39

40 Figure 39 Battery Module Numbering Controller Node Numbering The HP 3PAR StoreServ Storage system may contain two, four, six, or eight controller nodes per system configuration. The controller node chassis slots are located at the rear of the cabinet. From the rear of the cabinet, component numbering starts with zero (0) at the bottom-left corner and advances right and upward, refer to Figure 40 (page 41). Use the following table as a guideline for loading controller nodes into the chassis: Table 9 Controller Node Loading Order System Controller Nodes Loading Order 0, 1 0, 1, 2, 3 0, 1 0, 1, 4, 5 0, 1, 2, 3, 4, 5 0, 1, 2, 3, 4, 5, 6, 7 The following shows the numbering and positioning of the controller nodes in an HP 3PAR StoreServ chassis: 40 Component Numbering for HP 3PAR StoreServ Storage

41 Figure 40 Controller Nodes Numbering in the and As shown in Figure 41 (page 42), a controller node contains nine PCI slots. These slots contain PCI adapters, such as quad-port Fibre Channel and iscsi adapters. Each controller node has an administrative Ethernet port (E0), a dedicated Remote Copy over IP port (RCIP) (E1), and a console maintenance port (S0). Understanding Component Numbering 41

42 Figure 41 Controller Node PCI Slots and Port Numbering Each Fibre Channel adapter in a PCI slot has four ports. Each iscsi adapter in a PCI slot has two ports. PCI adapters assume the numbers of the PCI slots they occupy. In dual-port adapters, ports are labeled port 1 and port 2 in ascending order away from the adapter handle. In quad-port Fibre Channel adapters, the ports are numbered port 1, port 2, port 3, and port 4 in ascending order away from the adapter handle. Inside the controller node are control cache DIMMs and data cache DIMMs. Control cache DIMMs are located in control cache slots 0, 1, 2, and 3 (Figure 42 (page 43)). Data cache DIMMs are located on data cache slots (Figure 42 (page 43)). 42 Component Numbering for HP 3PAR StoreServ Storage

87 7 Power Off/On Procedures Powering Off the Storage System When it is necessary to power off the storage system, use the following steps to safely remove power from the storage system and the service processor (SP). NOTE: PDUs in any expansion cabinets connected to the storage system may need to be shut off. Use the locatesys command to identify all connected cabinets. locatesys will blink all node and drive cage LEDs. Note this information now, as it is needed for the last step in this procedure. To power off the storage system: 1. Connect the maintenance PC using the serial connection or SSH to the SP. See Connecting to the Service Processor (page 88). 2. Start an spmaint session. NOTE: If using SPOCC, on the SPOCC homepage, click Support > SPMAINT on the Web > InServ Product Maintenance > Halt an InServ cluster/node and skip to step In the 3PAR Service Processor Menu, select option 4, InServ Product Maintenance. 4. Select option 6, Halt an InServ cluster/node. 5. Select the desired system and confirm all prompts to halt the system. 6. Press x to return to the 3PAR Service Processor Menu. CAUTION: Failure to wait until all controller nodes are in a halted state as defined in Step 7could cause the system to view the shutdown as uncontrolled and place the system in a checkld state upon power up. This can seriously impact host access to data. 7. Allow 2-3 minutes for the system to halt, then verify the node status LEDs are flashing green (at a rate of three blinks per second) and the node hot-plug LEDs are solid amber (for the HP 3PAR StoreServ 10000, the node service LED is blue) which indicate the nodes have halted. For more information see the LED chapters in this manual. 8. Select option 1, SP Control/Status. 9. Select option 3, Halt SP. 10. When prompted, press Y to confirm halting the SP. 11. Wait approximately 30 seconds and verify if the LED on the front of the SP is no longer illuminated. 12. Remove AC to the storage system by turning off all of the PDU circuit breakers in the cabinet. 13. If necessary, replace the bezel and close and lock the rear door. Powering On the Storage System To power on the storage system: NOTE: The system takes approximately minutes to become fully operational providing it was gracefully shut down. If the system was powered off abruptly, powering on could take considerably longer. If the TOC is over a day old, it is considered invalid, and the setsysmgr tocgen command must be issued to select the appropriate TOC. Refer to the InForm OS CLI Reference for more information. Procedure 1 1. Turn on AC power to the cabinet(s) by turning on all of the PDU circuit breakers. Powering Off the Storage System 87

88 2. Verify that the blue LED on the front of the SP is illuminated. 3. Verify that all drive chassis LEDs are solid green and all controller node status LEDs are blinking green once per second. Connecting to the Service Processor Once you are connected to the SP, there are two SP user interfaces, SPOCC and SPMAINT, that you can use to perform various administrative and diagnostic tasks to support of both the storage system and the SP. Refer to Logging into the SP Onsite Customer Care Interface (SPOCC) (page 92). NOTE: Establishing a Secure Shell Session (SSH) is required when connecting the SP through LAN (Ethernet). Refer to Using PuTTY (page 91). Using a Serial Connection To connect the maintenance PC to the SP using a serial connection, refer to the appropriate HP 3PAR Storage System Maintenance Manual, Connecting the Maintenance PC chapter. Using an Ethernet Connection To connect the maintenance PC to the SP through the private Local Area Network (LAN) using an Ethernet cable, you must first configure the LAN settings on the maintenance PC. You can connect the maintenance to the SP using an Ethernet cable. When you use an Ethernet connection, you have to configure LAN settings on the maintenance PC (refer to Section (page 89)) and establish an SSH using PuTTY. Refer to Section (page 91). To connect using an Ethernet connection: 88 Power Off/On Procedures

89 1. Unlock and open the rear door of the storage system cabinet. If necessary, insert a red crossover Category 5 Ethernet cable (RJ45 to RJ45) into the proper Ethernet port of the SP (ETH1), refer to the following figures. Figure 85 Wintec Service Processor Ethernet Ports Figure 86 Supermicro Service Processor Ethernet Ports Figure 87 Supermicro II Service Processor Ethernet Ports NOTE: The Supermicro and Wintec Service Processor Ethernet port (ETH0) corresponds with the front NIC Port LED 1 and Ethernet port (ETH1) corresponds with the front NIC Port LED Connect the free end of the crossover Ethernet cable to the Ethernet port in the maintenance PC. 3. Power on the maintenance PC. 4. Configure the LAN settings on the maintenance PC. See Configuring the LAN Settings on the Maintenance PC (page 89).
