HP Offline Diagnostics Considerations
During cold-install or recovery on Itanium-based systems only, Ignite-UX
changes the boot disk partition layout to create a new HP Service
Partition (HPSP). Online and Offline Diagnostics use this 400MB
partition created at the end of the boot disk to hold tools and system
data.
The order of the partitions on the boot disk will be:
1. EFI OS Boot Partition (ESP)
2. HP-UX File System (HPUX)
3. HP Service Partition (HPSP)
During backup and recovery operations, Ignite-UX does not save or
restore any changes you make to the HPSP.
The HP Service Partition (HPSP) is not created or modified when you
update from a supported update path. (See “Supported Update Paths to
HP-UX 11i v2” on page 45.) OnlineDiag will continue to work properly.
Offline Diagnostics, however, will work with reduced functionality
without the HP Service Partition. See “Offline Diagnostics” on page 69
for more information.
To have full Offline Diagnostics functionality, do the following:
1. Update your system.
2. Back up your system with either make_net_recovery or
make_tape_recovery.
3. Reconfigure your boot disk partition layout to include the HP Service
Partition.
4. Restore your system with either make_net_recovery or
make_tape_recovery.
Consult the Ignite-UX Administration Guide for more details about
make_net_recovery and make_tape_recovery.
