(Step 4) Configure the onQ Appliance for cluster environment

Before You Begin: Go to (Step 3) Configure cluster for the onQ Service.

Use this procedure to configure the onQ Appliance for a cluster environment.

To configure the onQ Appliance for cluster environment:

1.	Stop protection.

2.	Upgrade onQ to 3.8 SP1, if not already at that release level.

3.	Log on to the hypervisor using Putty or Terminal.

4.	Download the SAN template and store it locally on the hypervisor (preferably under /var/run/sr-mount/xxxxxxxxx-xxxx-xxxx-xxxx folder).

5.	In the console command prompt, do the following:

a.	Extract the SAN template to its original size. When extracted the template should end with .xva extension.

# gunzip SAN-TEMP.cluster.xva.gz

b.	Run the following command, then record the uuid for the item with name-label set to VHD_SR:

# xe sr-list

c.	Using the uuid that you just identified, run the following command:

The import can take a long time. Nonetheless, the command returns immediately, and so you can monitor the import using XenServer’s log screen; also, when the import disappears from the ps -ef command output, the import completed.

# xe vm-import filename=SAN-TEMP.cluster.xva sr-uuid=<UUID>

To import a template and create the VHD on the hypervisor can take 10-15 minutes.

Next Step: Go to (Step 5) Enroll the cluster on the onQ Appliance.
