2 Obtaining the Software VMware Update Manager Cisco Nexus 1000V DVS setup and implementation For more information about Cisco Nexus 1000V setup and implementation, see the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3). Obtaining the Software Table 1 You can obtain your upgrade-related software from the following sources (Table 1): Obtaining Software Source Cisco VMware Description Download the Cisco Nexus 1000V Release 4.0(4)SV1(3d) software from the Cisco website. Download VMware software from VMware website. For information about your software and platform compatibility, see the Cisco Nexus 1000V Compatibility Information, Release 4.0(4)SV1(3d). Information About the Software Upgrade You cannot upgrade from Release 4.2(1)SV1(4) to Release 4.0(4)SV1(3d). Caution If the VMware vcenter Server is hosted on the same ESX host as a Cisco Nexus 1000V VEM, then a VUM assisted upgrade on the host will fail. You should manually vmotion the VM to another host before performing the upgrade. This section provides information about the software upgrade. A software upgrade consists of adding a new software version first to the Cisco Nexus 1000V VSM and then to its Virtual Ethernet Modules (VEMs). The sequence to upgrade the software is as follows: Upgrading the VSMs, page 4 Upgrading the VEMs, page 14 This section describes important points about the software upgrade: There are two methods of upgrading the software: the non-disruptive method and the disruptive method. An upgrade is non-disruptive or disruptive based on the version of your setup and also the method that you choose for upgrading. An ESX is termed as going through an upgrade when it is connected to a VSM during the upgrade procedure. An automated upgrade is traffic non-disruptive when you install one of the following: VMware patch ESX400/ESXi or the ESX400/ESXi UG or later on the host, and also use VMware vcenter Update Manager 4.0 Update 1 Patch 2, vcli build , and VSM Release 4.0(4)SV1(2) or later. 2

3 Information About the Software Upgrade Even if your ESX/ESXi host has patches greater than ESX/ESXi , without installing ESX/ESXi or ESX400/ESXi UG, a non-disruptive upgrade is not supported. Any ESX patches or updates after ESX400/ESXi UG will be backward compatible with the Cisco Nexus 1000V U2 VEM vib (cross_cisco-vem_v vib). VMware release ESX410/ESXi410 on the host, and also use VMware vcenter Update Manager 4.1 and VSM Release 4.0(4)SV1(3). A manual upgrade is traffic non-disruptive when the following conditions are met: While each vsphere host is attached to the Distributed virtual switch (DVS), migrate any running VMs to another host within the cluster. (As the VSM Release 4.0(4)SV1(1) cannot be Vmotioned, it must be powered off.) Place the host in maintenance mode and upgrade the VEMs. Follow the same method for other hosts in the data center. For details about how to determine what patch level you are using, refer to the Cisco Nexus 1000V Compatibility Information, Release 4.0(4)SV1(3d). Cisco does not support simultaneous VMware updates or patches in combination with Nexus 1000V upgrades. This document is designed specifically for Nexus 1000V upgrades across the same VMware platform. The upgrade process is irrevocable. After the software is upgraded, you can downgrade by removing the current installation and reinstalling the software. For details, see the "Recreating the Installation" section in the following document: Cisco Nexus 1000V Troubleshooting Guide, Release 4.0(4)SV1(3). Caution During the upgrade process, the Cisco Nexus 1000V does not support new additions of any vnics, vmnics, or new modules and does not support any configuration changes. vnic port-profile changes might render the vnic in an unusable state. If you are using a proxy server to connect the VMware Update Manager (VUM) to the Internet, you may need to disable the proxy before starting a VUM upgrade of your VEMs. In VMware versions before the VUM Update 1, the proxy prevents the VUM from communicating locally with the VSM. Therefore, automatic VEM upgrades may fail if the proxy is not disabled first. When you upgrade from Release 4.0(4)SV1(3) or Release 4.0(4)SV1(3a) to Release 4.0(4)SV1(3d), licenses apply as follows: On a Release 4.0(4)SV1(3) or Release 4.0(4)SV1(3a) VSM, you can install evaluation license files. If these evaluation licenses have not yet expired prior to the upgrade to Release 4.0(4)SV1(3d), these will be carried over after the upgrade to Release 4.0(4)SV1(3d) as is. The Release 4.0(4)SV1(3) or Release 4.0(4)SV1(3a) VSM has support for default/built-in evaluation licenses for 16 CPU sockets for a period of 60 days. If these default/built-in evaluation licenses have not yet expired before the upgrade to Release 4.0(4)SV1(3d), these will be carried over after upgrade to Release 4.0(4)SV1(3d) as is. 3

4 Upgrading the VSMs Any permanent licenses installed on a Release 4.0(4)SV1(3) or Release 4.0(4)SV1(3a) VSM will be carried over after upgrade to Release 4.0(4)SV1(3d) as is. When you upgrade from Release 4.0(4)SV1(2) to Release 4.0(4)SV1(3d), licenses apply as follows: On a Release 4.0(4)SV1(2) VSM, you cannot install evaluation license files. The Release 4.0(4)SV1(2) VSM has support for default/built-in evaluation licenses for 16 CPU sockets for a period of 60 days. If these default/built-in evaluation licenses have not yet expired before the upgrade to Release 4.0(4)SV1(3d), these will be carried over after upgrade to Release 4.0(4)SV1(3d) as is. Any permanent licenses installed on a Release 4.0(4)SV1(2) VSM will be carried over after upgrade to Release 4.0(4)SV1(3d) as is. When you upgrade from Release 4.0(4)SV1(1) to Release 4.0(4)SV1(3d), licenses apply as follows: On a Release 4.0(4)SV1(1) VSM, you can install evaluation license files. If these evaluation licenses have not yet expired prior to the upgrade to Release 4.0(4)SV1(3d), these will be carried over after the upgrade to Release 4.0(4)SV1(3d) as is. Any permanent licenses installed on a Release 4.0(4)SV1(1) VSM will be carried over after upgrade to Release 4.0(4)SV1(3d) as is. For more licensing details, see the Cisco Nexus 1000V License Configuration Guide, Release 4.0(4)SV1(3). Upgrading the VSMs This section describes the VSM upgrade steps. The following upgrade methods are described in the following topics: Prerequisites to Upgrading the VSMs, page 4 Upgrading the VSM from Release 4.0(4)SV1(2, 3, 3a, 3b, or 3c) to Release 4.0(4)SV1(3d), page 5 Upgrading the VSM from Release 4.0(4)SV1(1) to Release 4.0(4)SV1(3d), page 10 Prerequisites to Upgrading the VSMs The following are prerequisites to upgrading the VSM: You are upgrading the Cisco Nexus 1000V software to Release 4.0(4)SV1(3d). Network and server administrators coordinate the upgrade procedure with each other. The following files are available in external storage that you can access from the VSM. nexus-1000v-mz sv1.3d.bin nexus-1000v-kickstart-mz sv1.3d.bin You have saved all changes in the running configuration to the startup configuration to be preserved through the upgrade. You have saved a backup copy of the running configuration in external storage. For information about backing up a configuration file, see the Cisco Nexus 1000V System Management Configuration Guide, Release 4.0(4)SV1(3). 4

5 Upgrading the VSMs Upgrading the VSM from Release 4.0(4)SV1(2, 3, 3a, 3b, or 3c) to Release 4.0(4)SV1(3d) This section describes the VSM upgrade to Release 4.0(4)SV1(3d). For example purposes, the following procedure reflects an upgrade from Release 4.0(4)SV1(3) to Release 4.0(4)SV1(3d). This procedure is performed by the network administrator. To perform a VSM software upgrade to Release 4.0(4)SV1(3d), follow these steps: Step 1 Copy the new software release system image and kickstart image files to the bootflash file system of the active VSM. switch# dir bootflash: 154 Jan 27 15:21: ovfconfigured Mar 03 07:31: accounting.log Dec 09 13:56: lost+found/ Dec 09 13:57: nexus-1000v-kickstart-mz sv1.3.bin Dec 09 13:57: nexus-1000v-mz sv1.3.bin 4096 Dec 09 13:58: vdc_2/ 4096 Dec 09 13:58: vdc_3/ 4096 Dec 09 13:58: vdc_4/ Usage for bootflash://sup-local bytes used bytes free bytes total switch# copy scp://root@ /n1k-vsm-images/nexus-1000v-mz sv1.3d.bin bootflash: Enter vrf (If no input, current vrf 'default' is considered): root@ 's password: nexus-1000v-mz sv1.3d.bin 100% 20MB 1.1MB/s 00:19 switch# switch# copy scp://root@ /n1k-vsm-images/nexus-1000v-kickstart-mz sv1.3d.bin bootflash: Enter vrf (If no input, current vrf 'default' is considered): root@ 's password: nexus-1000v-kickstart-mz sv1.3d.bin 100% 20MB 1.1MB/s 00:19 switch# switch# dir bootflash: 154 Jan 27 15:21: ovfconfigured Mar 03 07:31: accounting.log Dec 09 13:56: lost+found/ Dec 09 13:57: nexus-1000v-kickstart-mz sv1.3.bin Jul 08 18:28: nexus-1000v-kickstart-mz sv1.3d.bin Dec 09 13:57: nexus-1000v-mz sv1.3.bin Jul 08 18:29: nexus-1000v-mz sv1.3d.bin 4096 Dec 09 13:58: vdc_2/ 5

Proceed to upgrade the VEMs. For details, see the Upgrading the VEMs section on page

14 Upgrading the VEMs Upgrading the VEMs This section lists important points about the VEM upgrade and describes the VEM upgrade process including the following topics: Prerequisites to Upgrading VEMs, page 15 Upgrading the VEMs from Release 4.0(2)SV1(2) or Release 4.0(2)SV1(3) to Release 4.0(4)SV1(3d), page 15 Upgrading the VEMs from Release 4.0(4)SV1(1) to Release 4.0(4)SV1(3d), page 21 Before upgrading the VEMs, note the following important points: The VEM upgrade starts when it is attached to the VSM. During the upgrade process, VEMs re-attach to the VSM. VEM software can be upgraded manually using the CLI, or upgraded automatically using VUM. VSM software can control and configure older VEM versions while continuing to support all features in the previous software version. To achieve a non-disruptive manual VEM upgrade, from Release 4.0(4)SV1(2) to 4.2(1)SV1(4), the user must vmotion the VMs out of the host that is to be upgraded, and then perform the VEM upgrade. If you are using VUM with the compatible ESX version as shown in the Cisco Nexus 1000V Compatibility Information, Release 4.0(4)SV1(3d) document, the host is automatically put in maintenance mode. An automated upgrade is traffic non-disruptive when you install one of the following: VMware patch ESX/ESXi or the ESX/ESXi UG on the host, and also use VMware vcenter Update Manager 4.0 Update 1 Patch 2, vcli build , and VSM Release 4.0(4)SV1(2) or later. Even if your ESX/ESXi host has patches greater than ESX/ESXi , without installing ESX/ESXi , a non-disruptive upgrade is not supported. VMware release ESX/ESXi410 on the host, VMware vcenter Update Manager 4.1, and VSM Release 4.0(4)SV1(3). Connectivity to the VSM can be lost during a VEM upgrade when the interfaces of a VSM VM connect to its own DVS. Connectivity between an active and standby VSM can be lost during a VEM upgrade when the VEM being upgraded provides interface connectivity to one of the VSMs. In this case, both VSMs become active and lose connectivity. To prevent this, use the following workaround: Before upgrading the VEM, power off the VSM provided with interface connectivity. The other VSM should be active. If you power off the active VSM, then the standby VSM will become active. Manually upgrade the VEM providing the interface connectivity. Restart the VSM that was shut down. If you are upgrading VEM using a Cisco Nexus 1000V bundle, follow instructions in your VMware documentation. For more details about VMware bundled software, see the Cisco Nexus 1000V Compatibility Information, Release 4.0(4)SV1(3d). 14

15 Upgrading the VEMs Caution Do not type the vemlog, vemcmd, or vempkt commands during the VEM upgrade process as it may impact the upgrade. Prerequisites to Upgrading VEMs The following are prerequisites to upgrading the VEMs: You are logged in to the VSM CLI in EXEC mode. You have already upgraded the VSM to the new software version. Network and server administrators coordinate the VEM upgrade with each other. Refer to Cisco Nexus 1000V Compatibility Information, Release 4.0(4)SV1(3d) for compatible versions of the VMware vcenter and VUM software.

Step 10 Step 11 Change the feature support level to enable the VSM to support all the new features in the new software version. See the Changing the Feature Support Level section on page 26 for more details. Power on the VMs. Changing the Feature Support Level Since Release 4.0(4)SV1(3d) is a maintenance release, it does not have a Feature Support Level. If you are already at Feature Support Level 4.0(4)SV1(3), you do not have to upgrade the Feature Support Level. This section describes how to change the feature support level and includes the following topics: Prerequisites to Changing the Feature Support Level, page 26 Changing the Feature Support Level, page 26 After all VEMs in the domain are upgraded, the network administrator changes the feature support level to allow the VSM to support all the new features in the new software version. Prerequisites to Changing the Feature Support Level The following are prerequisites to changing the feature support level: Changing the Feature Support Level You are logged in to the CLI in EXEC mode. After an upgrade, the VSM default is to support only features in the previous software version. Features added in the new software version are only supported and functional after the network administrator explicitly upgrades the feature support level. This procedure upgrades the feature support level. You can configure the VSM to provide support for the lowest VEM software version installed to maintain a consistent level of feature support. Before upgrading the feature support level, all VEMs in the VSM domain must be upgraded to the new software version. After the VSM feature support level is upgraded, VEMs with other software versions are not allowed to connect with the VSM. After the VSM feature support level is upgraded, it cannot be downgraded. To change the feature support level, follow these steps: 26

27 Changing the Feature Support Level This procedure is performed by the network administrator. For example purposes, the following procedure reflects an upgrade from Feature Support Level 4.0(4)SV1(2). Step 1 Verify the current level of feature support. switch# show system vem feature level current feature level: 4.0(4)SV1(2) switch# Step 2 If you are currently at Feature Support Level 4.0(4)SV1(1) or 4.0(4)SV1(2), you may elect to update to Feature Support Level 4.0(4)SV1(3). Display output based on the current VEM feature and the version of the VEMs. switch# system update vem feature level 1 4.0(4)SV1(2) 2 4.0(4)SV1(3) If all VEMs are upgraded to the new software version, then the feature support can be upgraded to the new software version. If even a single VEM is running the previous software version, then the feature support level cannot be upgraded, and the list will be empty. Step 3 Change the feature level to the desired index level from the list displayed in Step 2. switch# system update vem feature level 2 Old feature level: 4.0(4)SV1(2) New feature level: 4.0(4)SV1(3) Step 4 Step 5 After the feature level upgrade, VEMs with versions older than the feature level are no longer allowed to connect to the VSM. Verify the updated level of feature support. switch# show system vem feature level current feature level: 4.0(4)SV1(3) switch# Verify connectivity to the VEMs. switch# show mod Mod Ports Module-Type Model Status Virtual Supervisor Module Nexus1000V ha-standby 2 0 Virtual Supervisor Module Nexus1000V active * Virtual Ethernet Module NA ok Virtual Ethernet Module NA ok Mod Sw Hw (4)SV1(3d) (4)SV1(3d) (4)SV1(3d)

Prerequisites to Accepting the VEM Upgrade The following are prerequisites to accepting a VEM upgrade: You are logged in to the CLI in EXEC mode. Network and server administrators are coordinating the upgrade procedure. The VSM upgrade has occurred before the VEM upgrade. You have received a notification in vcenter that a VEM software upgrade is available. Accepting the VEM Upgrade The server administrator accepts the VEM upgrade after the network administrator has upgraded the VSM and notified vcenter server of the availability of the new VEM software version. To accept a request for a VEM upgrade, follow these steps: 28

29 Troubleshooting This procedure is performed by the server administrator. Step 1 Click the vsphere Client DVS Summary tab to check for the availability of a software upgrade (see Figure 1). Figure 1 vsphere Client DVS Summary Tab Step 2 Click Apply upgrade. The following actions occur: The network administrator is notified that you are ready to apply the upgrade to the VEMs. The network administrator notifies vcenter to proceed with the VEM upgrades. If you are using VUM, vcenter locks the DVS and triggers VUM to upgrade the VEMs. For details about the VEM upgrade performed by the network administrator, see the Upgrading the VEMs section on page 14. Troubleshooting This section provides troubleshooting guidelines for problems that may occur during an upgrade.
