Server Room Backups and Such

Goals of the backup:

- Backup a Production Blade (dom0)
(Zach) Helium was backed up (locally in the /backups directory, to the server_backups folder on the cosi polaris storage, and to production backups folder on animal)

- Backup Animals root file system
(Zach) Animal was backed up (locally in the /backups directory, to the server_backups folder on the cosi polaris storage, and to production backups folder on animal)

- Backup Righteous’ root file system (or attempt to) & possibly backup Righteous’ old file system
(Matt) Domain 0 and all guests backed up to animal.

- Copy backups (as 2 gb chunks, due to AFS file size restrictions) to COSI’s AFS Space
See above

- Install UPSs for Animal, the Raid Units, Hadoop, Switches, etc.
Will be taken care of another time

- Test configuration for shutdown upon power loss
(Matt) Everything seems to work

- Rewire some of the networking on righteous to include a direct link to the Clarkson switches (not through the blade center) and to the server room network (not through the blade center)
(Matt & Zach) Six wires were run from the switches to the Blade center (four are in use now, two for future expansion)

- Kick blades that don’t need server room network access off of the server room network
(Matt) Blades five and higher were kicked.

Extra things accomplished:
- (???) Disk check on raids A, B, and C of Animal

- (Zach) Hadoop backed up to polaris space

- (Matt) Blade Center Management moved to the internal network

- (Matt) Backed up windows servers

- (Zach) Backed up production and requested images (8) to raidA

- (Zach) Old, unused, images cleaned out (moved to the “old” folder)

- (Zach) All image xen configurations cleaned out and regenerated

- (Zach) Updated docs to reflect changes to which VMs are running

Estimated duration: ~2 hours
Actual duration: >>2 hours
