Failing
component
Continue after
failure? What happens and how to recover
Disk module Yes Provides the same features as the basic configuration
but with better performance and higher availability.
Applications continue running. System Administrator or
service provider replaces module.
SP Yes* If one SP fails, the System Administrator can access the
LUNs owned by the failed SP by accessing the
remaining operational SP with the other host. If a host
adapter fails, the System Administrator can access the
LUNs in the array with the other host adapter. The
System Administrator must change the path and SP
ownership of the LUNs for the failed SP or failed host
adapter by using LVM (applies to HP-UX 10.x and later)
and Grid Manager, respectively. There is no automatic
transfer of LUN ownership or path for this configuration
type.
Fan failure
within fan pack
Yes Applications continue running. System Administrator or
service provider replaces module.
Power supply Yes If a redundant power supply module is present,
applications continue running; otherwise, disk array fails.
Service provider replaces power supply and System
Administrator restarts the operating system, if necessary.
SCSI-2 adapter/
cable
No* I/O operations fail to all physical disk units configured on
SP attached to a failed SCSI-2 adapter/cable. System
Administrator can transfer control to the other SP by
changing host(s) and array configurations.
