Managing Serviceguard Sixteenth Edition, March 2009

NOTE: Data on shared disks, or on local disks in volumes that are not are touched
by the HP-UX installation process, will not normally be erased by the cold install;
you can re-import this data after the cold install. If you intend to do this, you must
do the following before you do the cold install:
• For LVM: create a map file for each LVM volume group and save it as part of
your backup.
• For VxVM: deport disk groups (halting the package should do this).
See “Creating the Storage Infrastructure and Filesystems with LVM, VxVM and
CVM” (page 206) for more information.
2. Halt the cluster applications, and then halt the cluster.
3. Do a cold install of the HP-UX operating system. For more information on the cold
install process, see the HP-UX Installation and Update Guide for the target version
of HP-UX: go to http://docs.hp.com, choose the target version of HP-UX
under Operating Environments and then choose Installing and
Updating.
4. Install any additional required software that did not come with your version of
the HP-UX Operating Environment.
5. Install Serviceguard. The Serviceguard version must be compatible with the version
of HP-UX installed in item 3 of this list. See the
Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in Compatibility and Feature
Matrix, at http://docs.hp.com -> High Availability ->
Serviceguard.
