change software state from CLAIMED to SCAN on command ioscan

[Michele Di Fiore]

Hello
I have a problem on superdome model 9000/800/SD32000.
When i start ioscan -fnCdisk on shell responce
change software state from CLAIMED to SCAN and manager hardware much slow.
See Attach log

Thanks mike

This is not a software state, its a hardware state.

It would appear you are having connectivity issues with your SAN.

You would need to run fcmsutil /dev/td0 and possibily other diagnostics to determine the issue.

I would also physically inspect the fiber cabling and the link lights on the fiber cards.

Also, contact the SAN administrator

When you do ioscan open another shell and check with ps to see if there are other ioscan's running at the same time (possibly EMS or script run from cron).

Hi MIke

We had the same problem on our system

We solved it by powering-off all monitor processes
Then we restarted them one by one checking I/O disk accesses carried out by each process

Let me know as sonn as possible

Hi Mike and Maurice

Maurice is right

I stopped all monitor processes and found that one of them launched ioscan command every 30 sec

Thanks a lot
