we are using HP-UX 11.23ia64 OS for oracle dataase. database stored in EMC SAN storage.
we are using volume manager and powerpath software.
iostat is not returing SAN disk information, I was able see the disk using ioscan command.
tried sar, vmstat, iostat unable to get SAN disk stats.
Is there a way I can get SAN disk io perfomance informaton.

Is the SAN volumes listed with ioscan -fnC disk ?
iostat reports activity on physical volumes. It sounds strange to me that no activity is reported.
I have no experience with EMC disk system and powerpath software but, with EVA disk system and SecurePath, iostat behaviour is normal.

$iostat |grep c8
