New disk not owned in NetApp or IBM N3700 SAN

I recently had a hard drive fail on my IBM N3700 SAN. The spare disk automatically took over when the disk failed. This is a good thing. IBM sent a replacement the next day and I was able to swap it out. Unfortunately the N3700 did not know what to do with the new drive. I assumed it would automatically make the new drive the online spare. Wrong.
Here are a few commands to try and fix the problem. You will need to be at the command line of your device for this to work.
disk show -n Show all the disks that are not assigned to a pool
disk assign auto Assign the unassigend disk to a pool automatically
disk show -v Show all the disks on your SAN
The new disk I received needed to be added to Pool 0 on my N3700. The disk assign auto command did not work. The following command did the trick though.
disk assign 0b.17 -p 0
0b.17 is the “Disk” name of the drive that was not owned. You can find out the “Disk” name after you issue the “disk show -n” command. The “-p” switch is for Pool and “0″ is the Pool name
To confirm that the new disk is in the correct Pool you can issue the “disk show -v” command.
