SUMMARY: SCSI errors

Hi,

Consultation with SUN tech support suggests replacing two of the disks in
the arrays. Although the errors appear to be distributed across a number of
drives it seems there are two particular units triggering the
faults. I guess these units are just not performing to spec and dragging the
whole rig down.

Cheers

Joe

Hi All,

Systems are E420Rs, A1000 disk arrays, L280 tape loader with DLT8000,
Solaris 8 + patches, RM6.2.2 + patches. Recently I'm seeing errors as shown
below. They seem to crop up during backup. Storage is attached via dual port
FWDiff controllers. If I try format/repair on the blocks listed bad then
format returns "block does not appear bad. repair anyway?"  I've got similar
errors on about half a dozen different disks. Any suggestions as to
cause/cure?
