In this article, you will learn how to upgrade a XenServer 5.5 resource pool with Update 2 for XenServer 5.5. Update 2 for XenServer 5.5 provides support for Windows Server 2008 R2 and Windows 7 guests. Update 2 also provides numerous bug fixes, along with an updated version of XenCenter.
Two methods exist that can be used to upgrade a resource pool:
1. Update all hosts in the pool at one time, which will require that all virtual machines (VMs) be shutdown.
2. Use the rolling pool upgrade method, which uses XenMotion to shuttle running VMs between pool members.
The advantage of Method 1 is that all pool members are updated at one time. The disadvantage is that all VMs must be shut down.
The advantage of Method 2 is that running VMs can be migrated to another pool member, so there is no down time for the VM. The disadvantages are that the pool members must be updated one at a time, and the update file must be removed from the pool master each time.
Both methods have three common steps:
1. Download the XenServer 5.5 Update 2 upgrade file.
2. Download the XenCenter Update 2 update.
3. Upgrade XenCenter.
Method 1 of upgrading a resource pool adds the following steps:
4. Shut down all VMs.
5. Upgrade XenServer.
6. Upgrade XenTools.
Method 2 of upgrading a resource pool adds the following steps:
4. Upgrade XenServer on the pool master.
5. Move any running VMs from the pool master to another pool member.
6. Reboot the pool master.
7. Upgrade a pool member.
8. Move any running VMs to another pool member.
9. Reboot the pool member.
10. Repeat steps 7 through 9 for each remaining pool member.
11. Upgrade XenTools once all pool members have been upgraded.
12. Move the VMs back to the original pool member.
