We're stumped, it appears as though someone issued a disk swap command on one of our filers, however none of us did.

Is there some other reason that this might occur, disk or SCSI bus glitch? As far as we can tell nothing has changed in the disk farm (syconfig -r matches the weekly email from this week).

scsi disks are more sensitive to glitch than FC ones, I interpret your problem as a glitch occured on the scsi chain as you would remove or insert a disk, filer interpreted that as a hot swap and did its usual job, i think you don't have to worry about that, if you really don't like this message, change for FC disks <smile>
