2 EMC IPMI Tool Overview EMC IPMI Tool Overview This document describes how to use the IPMI tool on a Windows workstation to access the SP console through serial over LAN on certain EMC storage systems. Certain storage systems provide console access over Ethernet instead of through the serial port. The IPMI tool is a network tool similar to ssh or telnet that interfaces with the BMC chip over an Ethernet connection by using the IPMI protocol. Note: The BMC only supports the Serial-Over-LAN features of IMPI. Purpose Scope This document describes how to: Install the IPMItool Use the IPMItool Configure a Windows workstation to access the storage system Use the IPMI tool under the guidance of authorized technical-support personnel. Do not run unsupported or third party IPMI utilities without approval from your EMC service representative. The IPMI tool is a Windows based utility that supports Windows XP, Windows 2000, Windows Vista, and Windows 7. The tool functions regardless of whether the system is in service mode, normal mode, or if the SP is rebooting. Audience Prerequisites The IPMI tool is intended for storage system administrators, EMC employees, EMC field partners, EMC and partner service and support personnel, and end users. A workstation must meet the following requirements to use the IPMI tool: A supported 32-bit or 64-bit Windows operating system Windows XP Windows 2000 Windows Vista Windows 7 An Ethernet port A standard straight-through Ethernet cable A hub or switch (for simultaneous access to SP A and SP B) A workstation must meet the following requirements for remote access to the console: A supported Windows operating system as previously listed. Two Ethernet ports, or one Ethernet port and a wireless interface. Client network setup provides more information about the setup. 2 IPMI Tool 1.0 Technical Note

3 Terminology (optional) Readers should have general knowledge about the terms listed in Table 1. IPMI tool description Table 1. Term IPMI BMC Admin user netsh Terminology Definition Intelligent Platform Management Interface. Operates independently of the operating system, and allows administrators to manage a system remotely in the absence of an operating system or system management software. Baseboard Management Controller (BMC). The intelligent microcontroller in the IPMI architecture. It manages the interface between the system management software and the platform hardware. This is the BMC console account. It manages and configures the BMC. This is the only default BMC account. Network Shell is a Windows command line tool to manipulate the internal network configurations. IPMI tool description IPMI tool is a Windows utility that uses a secure communication channel with the BMC to access the storage processor (SP) console of supported storage systems. This utility will require login credentials and an IP address to activate the console. Credentials - The username for an IPMI tool command is console, and the password is the chassis serial number of the system. The serial number for the system is located on the PSNT tag. IP Address - The BMC interface is configured with an EMC private IP address, reachable only through a direct connection with another computer on the same private subnet. Configure the client local interface with the EMC private IP address to establish communication between the client and the SP. This tool does not have a GUI interface. The command prompt is the only way to use the IPMItool. IPMI Tool 1.0 Technical Note 3

4 IPMI tool installation IPMI tool installation The IPMI tool utility can be found at (registration required) by searching for IPMI Tool. Figure 1. Example IPMI Tool search result Complete the following steps to install the IPMI tool on the Windows client: 1. Use Widows Explorer to create a new folder and name it ipmitool. You will use this folder to hold the files to be extracted. 2. Double-click ipmitool-1.0.zip and specify the location to place the extracted files. Figure 2. Specify location 4 IPMI Tool 1.0 Technical Note

5 IPMI tool installation Figure 3. Locate folder Figure 4. Select folder The system displays a message when the IPMI tool successfully extracts the files. Figure 5. Install successful IPMI Tool 1.0 Technical Note 5

6 Client network setup 3. Verify the following files are installed in the ipmitool folder you created. cygcrypto dll cyggcc_s-1.dll cygwin1.dll cygz.dll ipmitool.exe Figure 6. Verify IPMI tool files Client network setup Contact your service provider if any files are missing. There are two troubleshooting scenarios in which to access the SP console: Case 1: The storage system administrator is performing troubleshooting steps. You will be connecting the Windows client to a network hub or switch on the same subnet as the storage system to allow simultaneous access to both SPs, as shown in Figure 7. 6 IPMI Tool 1.0 Technical Note

7 Client IP address configuration Figure 7. Local user access to the storage system console If simultaneous access to both SPs is not required, connect the client directly to the Ethernet service port on one SP. Case 2: the storage system administrator is running a WebEx session to allow remote access to the SPs. Connect the Windows client as described in Case 1. Additionally, connect the client to a public network with a second Ethernet connection, or a wireless connection, as shown in Figure 8. Share the WebEx session over the public network connection to allow a remote user to access the private network connection to the storage system. Note Note A crossover cable is not required. A standard straight-through Ethernet capable is sufficient. If the Windows client does not have a second Ethernet port or a wireless connection, use a USB Ethernet adapter to add a second port. Figure 8. Remote user access to the storage system console Client IP address configuration The BMC interfaces of the Storage Processors are configured with EMC private IP addresses: for SP A, and for SP B. These IP addresses cannot be changed. The client must have an IP address on the /24 subnet to access the SP console. IPMI Tool 1.0 Technical Note 7

8 Client IP address configuration Complete the following steps to configure the client IP address: 1. Access the Windows Control Panel. 2. Access the network settings: a. In Windows 7, select Network and Sharing Center. b. In all other supported Windows versions, select Network Settings. 3. Identify the interface that is unplugged. Figure 9. Identify the unplugged network interface 4. Locate the RJ-45 10/100/1000 Ethernet service port on each SP. Though the location of the service port on the SP will vary depending on the system type, all systems use the same wrench symbol to mark the service port. Figure 10. Wrench symbol indicating the storage system service port Note If you have trouble locating the SP service port on your system storage processors, refer to the Hardware Information Guide for your storage system on support.emc.com for the exact port location. 5. Connect the unplugged interface on the client to the storage system service port, an Ethernet (RJ-45) 10/100/1000 LAN port. 8 IPMI Tool 1.0 Technical Note

9 Client IP address configuration The interface status changes to Connected, as shown in Figure 11. Figure 11. Connected 6. Open a Command Prompt window and use the netsh utility to set the EMC private IP address on the client: Note netsh is a Windows command line tool to configure the IP address on the LAN interface. This utility is available on all supported Windows platforms. netsh int ip set address <interface name> static <ip address> <netmask> <gw> <gw_metric> The interface name must match the interface name displayed by the ipconfig command. netsh returns a status of OK after completion. 7. Only for the users connected with the EMC corporate network using Cisco AnyConnect: Cisco AnyConnect is used to connect with the EMC corporate network. This software blocks the other interfaces from sending or receiving the packets. In order to access the SP console, disable the Cisco AnyConnect Driver in this interface as shown o o Uncheck Cisco AnyConnect Network Access Manager Filter Driver Click OK to confirm the changes.

11 Access the SP console with the IPMI tool Access the SP console with the IPMI tool The IPMI tool communicates with the BMC, and redirects the serial console communications over Ethernet. From a Command Prompt window, navigate to the folder containing the extracted IPMI tool files and run the IPMI tool to access the SP console. A sample command is provided below: ipmitool.exe -I lanplus -C 3 -U console -P <password> -H <host> sol activate Where: lanplus causes the IPMI tool to use secure communication. console is the fixed BMC username <password> is the PROD ID/SN value on the storage processor chassis serial PSNT label. Refer to Figure 14 for PSNT locations on possible storage processor chassis types. <host> is the BMC IP address o SP A: o SP B: Figure 14. Possible PSNT locations IPMI Tool 1.0 Technical Note 11

12 Access the SP console with the IPMI tool Locate the chassis serial number on the PSNT label affixed to your system. The PSNT for your system is located on either a pull out tag on the front or a hanging tag affixed to the back of the storage processor chassis. Note If you have trouble locating the PSNT with the PROD ID/SN value on your system storage processor chassis, refer to the Installation Guide for your storage system on support.emc.com for the exact tag location. Figure 15 shows a typical IPMI tool console view. Connect to the SP console, and use it as a serial console. ~ Accesses the IPMI tool help options ~ Terminates the IPMI tool session Figure 15.

14 WebEx sessions with EMC laptop and Console Access Figure 20. SP initialization (5 of 5) WebEx sessions with EMC laptop and Console Access In order to share WebEx session with the EMC internal support team, the user needs to connect with the EMC network over wireless network using Cisco AnyConnect VPN agent. The SP console needs to be accessed over the wired network (as described in the Client IP Address Configuration" session). Please follow these steps to connect with the EMC corporate LAN network. Connect exclusively to the wireless network to avoid automatic switch from wireless network to wired network. Thus, the wireless network is used to access EMC corporate LAN and the wired network to access the console of the SP. Figure 21. Connect exclusively to the wireless network. 14 IPMI Tool 1.0 Technical Note
