Adapter shown as offline
If the host bus adapters (HBAs) on HP 9000 and HP Integrity servers go offline, this situation does not necessarily indicate that an error occurred.
Setting domain IDs
For HP 9000 and HP Integrity servers, you can set the domain IDs before building the multiswitch fabric and before rezoning.
Attaching HP hosts to a clustered system
When you attach the HP 9000 or HP Integrity server to a system that presents volumes from more than one I/O group, you must implement a specific configuration to immediately view any new disk mappings without having to restart the host.
Starting ServiceGuard packages with degraded volumes
If you use ServiceGuard and PVLinks in an HP 9000 or HP Integrity system environment, the package startup time can take 20 - 60 minutes when you use the vgchange -a e VolumeGroupName command to start a package that contains a degraded volume.
