Feb 18 11:06:56 hostname vmunix: SCSI: Read error -- dev: b 31 0x034000, errno: 126, resid: 2048,

Feb 18 11:06:56 hostname vmunix: blkno: 8, sectno: 16, offset: 8192, bcount: 2048.

can someone tell me how to interpret this error message to find out what is complaining?

Hi,

31 is the major number of this device which is a disk. 034000 gives you the path.

Looks like there is a problem with one of your disks. Do a ll /dev/dsk |grep 34000 to find out the disk that is affected.

You have a problem with /dev/dsk/c3t4d0.

Hi Chris,

it seems, that one of your disks ist not okay and dying. Do a: ll/dev/dsk/ an you see which disk it is (0x034000 ist cxtxdx).

Also you can use the logtool of the cstm.

#cstm
#ru logtool
#sr
(Press Enter)

Then you see all I/O Errors of your system.

Bye Markus

Use the excercize option to test the drive.

I think eventually you'll get an lbolt and need to replace the drive.

It could be cables, scsi card or drive cage if your system has one. You need to keep an eye on this one. I'd think about mirroring or getting data off the affected drive.
