Hello:

To find the broken disks, search for the minor numbers 013000 and 010000 under /dev/dsk or /dev/rdsk and then you'll see the device file as following:

ll /dev/rdsk/|head
total 0
crw-r----- 1 bin sys 188 0x006000 Jun 18 14:44 c0t6d0
crw-r----- 1 bin sys 188 0x0a0000 Sep 21 2006 c10t0d0

With this information you can identify the broken disks with ioscan -fnC disk | grep cXtXdX and in the output of ioscan you'll find the hardware path of the HBA. For expample, if ioscan shows 0/0/2/0.2.0, then your HBA is 0/0/2/0.

Regards;

J. Bravo.

Hi ,

Scsi errors within the syslog are usualy a good indication that there is a hardware issue with a diskdrive.

Do

#ll /dev/dsk |grep minor number

Shalom,

multiple alerts as you have received sometimes indicate a controller or drive cage failure. Hardware is most likely going to at least need some attention.
