One of two hard disks (Slot 2) is not visible in OS (HPUX 11.23)

[aique]

Hi,
I have 2 new rp4440 machines. Problem is, hard disk in slot 2 of both servers is not visible in the OS (HP-UX 11.23). But its LEDs are showing normal behaviour. I even have reinstalled the OS but of no use.

Please advice.
Thanks,

Do you see it as UNCLAIMED or NO_HW when you run ioscan command?

Try to pull it out and run ioscan and it should show NO_HW then wait for one or two minutes and then re-seat it, run ioscan again.

check syslog for any errors during above steps.

Hi,
I didn't find any entry for this hard disk in ioscan -fnC disk output. I also have pulled and re-inserted the disk and recorded the syslog out for events. Please find attached the log file and suggest.

Thanks and regards,

Hi Abdul

Looks like your servers have raid controllers installed and the 2 disks are part of a raid 1+0 mirror set.So the OS will only see 1 "disk", which is actually the logical drive created by the raid controller.

So there is no problem here :)

Hi there.
Pls check the existence of the directory /opt/raidsa/bin .
If it exists, there should be a file 'sainfo'. Pls read the manpage.

Thanks to all,
Yes there is a Smart Array Controller installed in the server and also Raid 1+0 is configured on it.So Problem is resolved now. Theard is now being closed.
Thanks to all once again.
