When upgrading NetScaler appliances in a high availability setup to software release 11.1, be sure to upgrade the secondary appliance first, and then upgrade the primary appliance.
Note: If you encounter any issues during the upgrade, roll back to version 11.0 for services managed by the NetScaler appliance.
There are two ways of implementing this deployment on a partitioned appliance.
- Tagging few VLANs before deploying NetScaler 11.1
- Enabling VLANs as "Shared" after deploying NetScaler 11.1
This scenario is the least preferred scenario as it involves configuration loss during the software upgrade.
- Follow steps 2 to 20 of the previous procedure to upgrade the secondary appliance with NetScaler 11.1 software.
- After you have upgraded the software on the secondary appliance, VLAN bindings to partitions are lost, and the configuration depends on the VLAN inside the partition during the upgrade process.
- Now enable the untagged VLANs of any port interface "Shared" and bind the "Shared" VLAN to the partitions and configure the VLAN inside each partition.
- set vlan 10 -sharing enabled
- bind partition p1 -vlan 10
- From the command line interface of the appliance, type "save config" command to save the configuration in all the affected partition and the default partition.
- If the appliance is not a primary appliance, run the "> force failove" command to perform a force failover to ensure that the appliance is a primary appliance.
- Upgrade the new secondary (formerly the primary) appliance with NetScaler 11.1 software and reboot it to synchronize its configuration from the primary appliance.
- From the command line interface of the primary appliance, type the "save config" command to save the configuration in the primary appliance.
- If the appliance is not a primary appliance, run the "> force failover" command to perform a force failover to ensure that the appliance is a primary appliance.
- Verify that the appliance is a primary appliance.
