Racked new equipment.

November 11, 2010

MK -- Installed CRAB_2_7_5_patch1

MaKi, MiKo, MaTo -- Racking

Moved one WN above the KVM, moved two INs up directly underneath disk vault, inserted new UPS and new PDU, moved power cables around. Added new SE node.
Upgraded RAM on HN and GN to 16GB. Added two port NICs on HN and GN to give a total of 4 ethernet ports on each node.
Moved entire internal network over to new network switch, configured via serial cable to get IP via DHCP query. Got Rocks to recognize it and successfully booted and Kickstarted nodes into Rocks network using new switch.

MaKi & MiKo -- Configured replace-partition.xml for 2TB disks, installed nodes into rack

MaKi = Marguerite Tonjes, modified replace-partition.xml for new 2TB disks
- Used PXE boot and insert-ethers --replace compute-0-x since installing new disks meant the sytem doesn't know anything about Rocks.
- Attempt to use python to automatically partition drives following Rocks docs failed entirely, it created one / logical volume partition for both drives. New R510s will simply have to be in a new appliance group that is identical to the compute nodes except for the partitioning scheme.
MiKo = Michael Kossin, installed new compute nodes and switch into rack.
