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 about untagged VLANs and how to enable it as shared for VLAN deployment from an earlier release to 11.1 release. This is a 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. Note: Make sure you first enable the untagged VLANs as shared before you bind it to a partition.
- unbind partition p1 -vlan 10
- 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.
