NetApp 7.3.x Simulator - Squeezing Space

The default installation of the NetApp simulator creates you three 100MB disks as aggr0 and puts vol0 into it. You can have up to 56 1GB disks in the sim which isn't many but it's the sim, there aren't supposed to be enterprise grade applications on it. You might want to add that little bit more space, all three gigabytes of it. Here's what you do. It's here more for my own reference because I run about five of these things at home because I really don't want to pay $200 a month for a FAS2040 electricity bill and still not have SnapMirror and SnapVault between system capabilities.

Stuff you need to do:
Edit /sim/setup.sh to change maxdisks to 56. (gedit is fine)
Set up filer as per instructions, make disks 56. Paul Hargreaves wrote comprehensive instructions so I won't bother here.
Create a new aggregate.
Create a new volume 'vol1'.
License all the extras from the license.htm file - including SnapMirror.
Configure SnapMirror to accept connections from all the sims you need.
Configure SnapMirror.
Initialize the SnapMirror and note the rejection works properly.
Restrict vol1.
SnapMirror the volume which will work properly this time.
Wait for mirroring.
Quiece the mirror.
Break the mirror.
Run: vol options vol1 root.
Reboot the filer.
Remove vol0.
Rename vol1 to vol0.
Destroy aggr0.
Remove the three small disks that used to be aggr0.
Shut down the sim.
Delete the three 100MB disks from the /sim/disks directory and also the 'reservations file'.
Boot the sim. (just run bash runsim.sh from the terminal window)
Make sure all is well and only 53 disks exist.
Shut down the sim.
Run setup.sh again and add the three disks.
Start the sim.
You're done. You have 56, 1GB disks.
