Summary (brief) Bus Device Reset Message

Greetings,

Thanks to those who replied.

>From the terse: "call sun and replace the disk"

to the helpful: probe-scsi? yes device is seen
                  : spinning up? yes it appears to
                  : this error seen on an E250; apparently this 12 pack is
not fully supported on a E250

No one commented on the possibility of a corrupt device file.

Conclusion:

As the 12 pack is behaving strangely now (drive indicator lights coming on
before the drive spins up) I am replacing the backplane, power supply and
the suspect disk.

Original question:
