Mailing List Archive: disk_erase

I powered off a NetApp rather abruptly. Oops.

Since then, one of my disks reckons it's broken.

nacolt1> sysconfig -r
Volume vol0 (root)

I believe there's a command disk_erase_label which I can use to (at my own
risk) try to recover this disk. But it needs a disk id parameter. I'm
guessing that the disk id is 8.2 (the missing one from the info above) - but
that doesn't work.

nacolt1*> disk_erase_label 8.2
bad disk_name: 8.2

Is there some other disk id I need to find out - or is this just an
indication that the disk really is broken?

This is an old ONTAP. version says:

NetApp Release /n/snapon/dnoveck/537: Tue May 29 08:30:47 PDT 2001

Under priv set diag you can us the disk unfail command to make a broken disk
a spare again but this is (as you said) used at your own risk.

Is that what you are looking for? I have not had to use this command myself
so I don't know what the real-world implications are.
C-

m5*> disk
usage: disk <options>
Options are:
fail <disk_name> - fail a file system disk
remove <disk_name> - remove a spare disk
swap - prepare (quiet) bus for swap
unswap - undo disk swap and resume service
scrub { start | stop } - start or stop disk scrubbing
unfail <disk_name> - make a failed disk a spare again
shm_stats [<disk_name>] - Storage Health Monitor stats for a disk
