Re: FC60 issue (plz help)
After more verification of the amdsp -a output attached, i noticed the following line corresponding to LUN 31 or UTM
31 OPTIMAL 20.0 MB A 0 32 Can't identify
Any help will be much appreciated.
Thanks in advance

Re: FC60 issue (plz help)
you will get this error in hpux, when there is a disturbance is in the connectivity (like some one took away cable for some reason for a moment). As the amdsp is not revealing any error on controller, it is safe to ignore this.
The disk mentioned by you should be a failed disk which may require replacement. You may contact HP support for replacement.

Re: FC60 issue (plz help)
However, LUN31 is a special LUN for UTM usage and normally should not contain any disk and instead of the "Can't identify" state it should be stating "UTM:GOOD" only in normal behaviors.

Re: FC60 issue (plz help)
Yes, the disks that were part of lun31 has some issue.
Some of the disks are in "unassigned" state . (disks - 2:3, 4:3, 6:3)
If you have captured amlog HP support should be able to help. Or if you can upload amlog here, some one on the forum might be able to look further.

Re: FC60 issue (plz help)
Hi,
Logs does report removal/reset of controller. As there is no issue with controller now there is no action requried.
I have not seen this issue with UTM lun before. If you contact HP support they may be able to check it. OR you may try disabling/enabling the UTM as per the advanced user guide page 322 at http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c00744713/c00744713.pdf
This guide also mentions methods to collect detailed logs with a specified time frame.

Re: FC60 issue (plz help)
Hi again and thaks for your help.
In fact, after replacing the controller in slot A, it seems that it took care of the issue.
Really weird as no logs in the amdsp -a output showing controlA is bad.
Those FC60 are really weird :)
Thanks once again for your help.

Re: FC60 issue (plz help)
Hi All,
after replacing the controller A, everything went GOOD for a while but now we're back to the same situation as before with the controller A status : "UNKNOWN" (file in attachment) .
Those FC60 are so tricky so i dunno if im missing something here; any help / suggestion is precious to me.
Thanks in advance
