 You are correct. The Celerra does not need to be brought down to add
disk. First present the disk to the Celerra in some manner dependent
on your backend configuration-- Symmetrix or Clariion, Integrated or
Gateway. Then you can create the device files for them using the
server_devconfig command like so:

"server_devconfig ALL -list -scsi -disk" -- this shows the current
devices (not the new ones). Use this to compare against the later
"list" command

"server_devconfig ALL -probe -scsi -disk" -- this interrogates the
backend for any new targets. You should check the output here to see
that the new devices are found.

"server_devconfig ALL -create -scsi -disk" -- this creates the device
nodes on the datamovers and controlstation

"server_devconfig ALL -list -scsi -disk" -- compare with the first run
to see the disk that has been added.

Now you can create your volumes, and filesystems with either the
nas_volume/nas_fs commands or the Celerra Manager.

For more information check powerlink for the Celerra administration
guides.

HTH,

 I have a problem. I presented the disks to the Celerra and I click on the "rescan" button (I think that it was the same that the server_devconfig -probe and -create commands.

But when I want create a volume (slice, meta, ...) shows the next one:
Error 3147: Volume XXX resides on a reserved disks. (XXX is the name of my disk)

The nas_disk -info XXX show that the disk is NOT in use.

Any idea?

Thanks.
