4 racks with blade servers, 52 servers per rack, will be dropped off tomorrow. Not all will be turned on as 5% of the servers are kaput. So the first step is to build a fully working rack. Memory footprint of the servers is either 8 or 12 GB. Chipset is AMD Operon dual 248 CPUs at 2.4 GHZ.

Since there is no budget we will be installing CentOS with Lava as the scheduler. More details to come.

Mental Notes pour mois …

• no need to block ssh access to swallowtail or petal tail

• bring job count up, delete accounts files

• make sure dhcpd is stopped on swallowtail
• remove compute-01
• back up 'good files'

• release nodes on swallowtail
• PXEboot
• add to new cluster
• custom image

• scp over lsb.accts files from lsf_archive
• also the disk and queue log files
• had to stop|start lsf_daemons to get LSF going

• reroute the power cords on side of rack
• free ports 47*48 on both ethernet switches

• reconfigure LSF queues (&licenses, remove & add)

• open petaltail for business (jobs can be submitted)

• keep swallowtail up for a few days (no access)

• reimage swallowtail as master LSF candidate

• reposition swallowtail as LSF master, petatail as LSF secondary (and repository manager)
