RX4640 - Physical Disk Failure Detected

[Nelson Laracuente]

Good morning,

I have an RX4640 machine that this morning in syslog.log is displaying the following:

Aug 24 07:02:31 ux01 vmunix: CISS: RAID SA controller on hardware path 0/1/1/0/4

I have contacted HP and they indicated that this drive is on our RAID array. I had our networking staff look at our EMC2 to see if any drives were detected in error. They came back and found nothing. I consulted with other staff internally and they indicate that the error is not on our SAN but with an internal drive on the RX4640. This is the path that I get when I do an ioscan which matches the path on the error for syslog.log:

disk 1 0/1/1/0/4/0.0.0 sdisk CLAIMED DEVICE HP
LOGICAL VOLUME
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
/dev/dsk/c2t0d0s1 /dev/rdsk/c2t0d0s1
/dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0s2

Also this drive is showing in a CLAIMED state. If there were any errors wouldn't that status be different than CLAIMED.

Any ideas here???? Is there a utility within HP-UX that will scan the drives and determine if there is an error?? Thank you for your help.

P.S. This thread has been moved from Disk to HP-UX > sysadmin. -HP Forum Moderator

If I see well this is a disk connect to a smart raid controller?

In this case there is no unix command to see a disk error. Unix only sees the created lun.

Use the saconfig utility to check your array

Thanks for your help. I did an sautil /dev/cissX and it showed me that the disk is not responding. I am having HP come out and replace the drive. Thanks again.
