Chapter 4. Upgrade Instructions

38

Note

In the latest XenServer upgrade procedure, even after putting the master host into

maintenance mode, the master host continues to stay as master.

Any VMs running on this master will be automatically migrated to other hosts, unless there is only

one UP host in the cluster. If there is only one UP host, putting the host into maintenance mode

will stop any VMs running on the host.

5. Disconnect the XenServer cluster from CloudPlatform. It will remain disconnected only long

enough to upgrade one host.

a. Log in to the CloudPlatform UI as root.

b. Navigate to the XenServer cluster, and click Actions – Unmanage.

c. Watch the cluster status until it shows Unmanaged.

6. Upgrade the XenServer software on the master host:

a. Insert the XenXerver CD.

b. Reboot the host.

c. Upgrade to the newer version of XenServer. Use the steps in XenServer documentation.

7. Cancel the maintenance mode on the master host.

8. Reconnect the XenServer cluster to CloudPlatform.

a. Log in to the CloudPlatform UI as root.

b. Navigate to the XenServer cluster, and click Actions – Manage.

c. Watch the status to see that all the hosts come up.

9. Upgrade the slave hosts in the cluster:

a. Put a slave host into maintenance mode.

Wait until all the VMs are migrated to other hosts.

b. Upgrade the XenServer software on the slave.

c. Cancel maintenance mode for the slave.

d. Repeat steps a through c for each slave host in the XenServer pool.

10. You might need to change the OS type settings for VMs running on the upgraded hosts, if any of

the following apply:

• If you upgraded from XenServer 5.6 GA to XenServer 5.6 SP2, change any VMs that have the

OS type CentOS 5.5 (32-bit), Oracle Enterprise Linux 5.5 (32-bit), or Red Hat Enterprise Linux

5.5 (32-bit) to Other Linux (32-bit). Change any VMs that have the 64-bit versions of these same

OS types to Other Linux (64-bit).
