5. Uninstall the previous version of HP Clustered File System from each
server in group A. Use Start > HP Clustered Gateway > Uninstall HP
CFS. Select the checkbox to “Keep the existing HP Clustered File
System configuration.” You will need to reboot the server when the
“reboot” popup message appears.
NOTE: Do not use the Add/Remove Programs option on the Control
Panel to remove HP Clustered File System. This method will
remove your cluster configuration. If you want to use
Add/Remove Programs to remove HP Clustered File System,
use the “Change” option and then select “Keep the existing HP
Clustered File System configuration.”
6. On each server in group A, upgrade the operating system and/or
service pack if necessary.
7. If you will be adding third-party MPIO software to the cluster, install
it on each server in group A according to the product documentation.
8. On each server in group A, upgrade HBA drivers if necessary. In
particular, if you have upgraded to Windows 2003, you will probably
need to install a new HBA driver. (For a list of supported HBA drivers,
see the compatibility information on the HP Web site.)
9. If necessary, reboot the servers in group A. (You will need to reboot
the servers if this step is required by an operating system upgrade or if
you installed a new HBA driver in step 8.)
10. If you upgraded or reinstalled the operating system on the servers in
group A, run the HP mxcheck utility on the servers. This utility
verifies that the servers configuration meets the requirements for
running HP Clustered File System.
To run mxcheck, insert the HP Clustered File System CD into the CD
drive or go to the directory where you downloaded the product and
then double-click the file mxcheck.exe. Output from the utility appears
on the screen and is also written to the Application Log section of the
Event Viewer. We recommend that you fix any problems identified by
mxcheck before you install HP Clustered File System.
