Upgrading Veritas Replication VIB

When you apply the Resiliency Platform update to Resiliency Platform components in an environment where VMware virtual machines are configured for recovery to on-premises data center, you need to upgrade the Veritas Replication VIB on all the ESXi clusters using the Veritas Resiliency Platform web console.

During the process of applying the update, the hosts are required to be in maintenance mode. If automatic DRS is enabled for the cluster, VMware vCenter automatically puts all the ESXi hosts in maintenance mode in a sequence by moving the virtual machines to other available ESXi host (based on the policy or capacity) and then update Veritas Replication VIB. If DRS is not enabled, then you need to manually put all the ESXi hosts in maintenance mode to perform the operation.

Steps to automatically upgrade the Veritas Replication VIB

Prerequisites
Ensure that the DRS is properly configured. Also ensure that the DRS automation level is set to 'Fully Automated' on the ESXi Cluster.
Navigate

Settings (menu bar) > Infrastructure > Details View

You can also access this page from the Quick Actions menu.
Select the data center and click Data Mover.
On Resiliency Platform Data Mover tab, in Replication ESXi Clusters table, do one of the following:
- Click Upgrade Veritas Replication VIB. In the Upgrade Veritas Replication VIB on ESXi Cluster wizard, select one or more clusters where you want to upgrade Veritas Replication VIB.
- In the list of clusters listed under Replication ESXi clusters, right click the cluster where you want to upgrade the Veritas Replication VIB.
Select Use SORT URL to upgrade Veritas Replication VIB if you want to use the direct link of SORT URL to upgrade the Veritas Replication VIB on the clusters. In this case, you need to ensure that the SORT URL is accessible from the vCenter server.
Alternatively, you can use IMS to upgrade Veritas Replication VIB on the ESXi clusters.
Click Next to initiate the process of upgrade on the clusters.

Note:

If the ESXi hosts are upgraded from 6.x version to 7.x, upgrade the Veritas Replication VIB immediately.

Manually upgrading Veritas Replication VIB

It may happen that the DRS is not configured properly and you need to manually put all the ESXi hosts in the maintenance mode to perform the operation. If some of the virtual machines in the cluster are running on local storage and DRS is not properly configured, you need to manually upgrade the Veritas Replication VIB using following steps. The below steps are performed to manually upgrade the Veritas Replication VIB using the below example with assumptions - Two ESXi hosts in source cluster: ESXi-1 host and ESXi-2 host

Steps to manually upgrade the Veritas Replication VIB

Login to source vCenter server.
Keep DRS mode enabled and DRS Automation mode as Manual on the ESXi cluster which needs VIB upgrade.
Login to RM console and try to upgrade VIB on ESXi cluster. The Upgrade VIB operation fails along with error 'Host cannot be into maintenance mode to complete VIB installation' and this is expected because the DRS Automation mode is Manual.
The VIB status on the ESXi cluster changes from Installed to Partially Installed. This is expected behaviour as the cluster has a new version of VIB and ESXi has older version of VIB installed.
You need to ensure the SORT URL is accessible from the vCenter server. Alternatively, you can use IMS to upgrade the Veritas Replication VIB on the ESXi clusters.
Migrate all the virtual machines from ESXi-1 to ESXi-2 using VMware vMotion or power off the virtual machine, if no host machine is available for migrate. Do not keep any virtual machine running on the ESXi-1.
Manually put the ESXi-1 into maintenance mode from the vCenter server. Later, the VIB upgrade will be automatically triggered on that ESXi by the vCenter server itself.
Note:
In case of upgrade VIB is not getting triggered on the ESXi automatically by vCenter server, execute the Resolve and Verify operation on the ESXi cluster from RM console which upgrades the VIB on that ESXi.
Once upgrading the VIB is complete on the ESXi-1, exit from the maintenance mode for ESXi-1.
Migrate all the virtual machines from ESXi-2 to ESXi-1 using VMware vMotion, or power off the virtual machines if no host is available for migrate.
Manually put ESXi-2 into maintenance mode from the vCenter server. The VIB upgrade is automatically triggered on the ESXi by vCenter server itself.
Note:
In case upgrade VIB is not getting triggered on ESXi automatically by vCenter server, execute the Resolve and Verify operation on the cluster from RM console which upgrades the VIB on that ESXi.
Once the VIB upgrade is complete on ESXi-2 , exit from the maintenance mode for ESXi-2.
Login into RM console and execute the Resolve and Verify operation on the cluster which should change the VIB status from Partially Installed to Installed.

For the cluster with more than two ESXi's, repeat the steps 5 to step 10 to complete the upgrade for all the hosts in the cluster before moving to the next cluster. Repeat the steps 1 to 11 to manually upgrade the VIB on the target ESXi cluster.

Upgrade VIB in stateless ESX

Following steps has to be followed to upgrade VIB in stateless ESX. These steps has been validated with a cluster of two stateless ESX hosts booted using an Image (for example ImgProf_Org). As an example, following steps uses VRP VIB 3.4 and 3.5 but the steps are same for any other version as well.

Steps to upgrade the Veritas Replication VIB in stateless ESX

A cluster with two stateless ESX hosts is up using an Image Profile (ImgProf_Org).
Clone ImgProf_org to ImgProf_VIB3.4 and include VIB 3.4 VIB by editing the software package.
Clone ImgProf_org to ImgProf_VIB3.5 and include VIB 3.5 VIB by editing the software package.
Create deploy rule AD_VIB3.4 and include image profile ImgProf_VIB3.4 and HP_vtstap in it.
Create deploy rule AD_VIB3.5 and include image profile ImgProf_VIB3.5 and HP_vtstap in it.
Activate AD_VIB3.4 on both the hosts.
Reboot both ESX hosts in the cluster.
Install VIB 3.4 using Resiliency Platform interface (This will install VIB on the cluster).
Upgrade Resiliency Platform to 3.5 version.
Upgrade VIB from 3.4 to 3.5 using Resiliency Platform interface (This will upgrade VIB on the cluster)
Activate AD_VIB3.5 for on both the hosts.
Reboot both the ESX hosts in the cluster.
