Getting SCSI errors. How do I tell what device?

I had a disk go bad. I removed it from the LV mirror. Still getting these messsages. Trying to determine if I have another disk failing.

Ray,

The device for which the resets are logged may be a robotics or changer device for a (virtual)tape library.

Major Number 203 is used for SCTL usually associated with these devices.

Looks like the command involved was a SCSI Inquiry command.

Re: Getting SCSI errors. How do I tell what device?

hi ray,

from the dev cb061000 we can see its a sctl device, not a disk.

cb = 203 major device file, so we can try and find out the device with

#cd /dev/sctl
#ls -la

you will see something like this

total 0
crw-r--r-- 1 root sys 203 0x000000 Jun 24 14:19 c0t0l0
crw-r--r-- 1 root sys 203 0x001000 Jun 24 14:20 c0t1l0


but likely to be a tape device or controller causing it
