I have a RX2660 server running HP-UX 11.23.
Two local RAID sets are configured. 3 72Gb disks in each.
An 'ioscan -fnC disk' takes some 45 seconds to respond. An 'ioscan' command with no options set takes close to or just over a minute to respond.
I have the cumulative patch PHCO_34720 installed, configured and verified.

Re: Slow ioscan on HP-UX 11.23
Most common cause of slow ioscan:
* Unterminated scsi connectors/devices.
* disks that have gone bad but still have power.
check /var/adm/syslog/syslog.log for lbolt messages.
Use mstm/cstm/xstm to test your disk devices

Re: Slow ioscan on HP-UX 11.23
As per my view 45 second it├в s ok, because ├в ioscan├в scan all attached devices. As you mention you have storages. Also check swapinfo ├в tam, system├в s filesystem, cup utilization etc.also check system logs, disks status.
