HP integrated Citrix XenServer 5.0 Release Notes

XenServer HP Edition Release Notes 11

Browse to the location where you have the embedded update file, then click Next. A progress bar is

displayed as the update is loaded.

8. When the update has finished loading, you are prompted to select the mode for applying the

update. Select Manual mode, then click Next.

CAUTION: You must select Manual mode in this step. Attempting to upgrade your pool using

Automatic mode can result in data loss.

9. Remove the upgrade media and reboot the server. When the server reboots, XenCenter loses its

connection to the pool. When it returns, it should reconnect automatically. If it does not, right-click on

the pool and select Connect from the context menu.

10. Repeat for all other servers in the pool, migrating VMS to the master and/or other members and

shutting down any VMs that are on local storage.

11. Update the PV drivers on the VMs once the pool servers are upgraded. See the XenServer VM

Installation Guide for details.

NOTE: XenCenter from release 4.0.1 or 4.1.0 does not work with XenServer hosts from

release 5.0.0. However, XenCenter from release 5.0.0 does work with XenServer hosts from

release 4.1.0.

Troubleshooting upgrades

If you experience trouble during the upgrade process, you can roll back to the previous image by holding

down the SHIFT or CAPS LOCK during boot and a menu is displayed. If this is the first upgrade you have

performed, option 1 will be the original system, and option 2 will be the new system (the current default).

If this is the second upgrade you have performed, option 1 will be the new system (the current default),

and option 2 will be the prior system. Upgrades 3, 4, and the rest are arranged similarly such that which

partition the newer and older software resides on switches, and the newer upgrade is always set as the

default boot partition. When you boot either system image from this menu, your selection will then be set

as the default option.
