SCSI error

Gregory Thomas — Wed, 02 Jul 2003 18:56:56 GMT

Is there a way to determine which SCSI card/device, etc is getting the following error?
SCSI: Read error -- dev: b 31 0x006000, errno: 126, resid: 2048

Thanks....Jim

It's /dev/dsk/c0t6d0.

lsdev will identify the major device (blk device 31) and the minor device is easy. Now you can do an ioscan -fn and look for /dev/dsk/c0t6d0 (or /dev/rdsk/c0t6d0) and match that to the hardware path.

cXt6d0 is a popular choice for boot drives so this might be bad unless you are mirrored.

Yep
ioscan -fnCext_bus (look for Instance 0)
-0x006000 (first 2 zeroes are for ext_bus instance 0,next 2 - are for scsi target=6 and lun=0) -> c0t6d0,most probably your system disk (as scsi id=6 is the next highest priority after id=7 which is a scsi adapter).

Run dd if=/dev/rdsk/c0t6d0 of=/dev/null bs=1024k for full drive read test.

Thanks guys.
Yep, it's the internal root disk.
Fortunately it's mirrored.

Is there an lbolt?

If so, you will soon need to replace it. I've only gotten those to go away when I triggered them by swapping a hot swappable drive while the system was running.

Since you are mirrored if the drive itself is hot swappable, you don't have a very hard install.
