• 12/03/10 David Holton arrives for training. Part of “resource for a week”. Replaced a disk that was already flagged as “predictive failure”. Biggest change in cluster configuration is how the MSA60 volumes were set up. We destroyed all that and rearranged three volumes across the scsi cables (that is vertical versus horizontal) and applied LVM on top.

• 11/25/10 Decommissioned two BSS racks (cluster sharptail) which will be donated Wellesley University. That freed up six L6-30 circuits. With James, three of them were pulled to the area were the Flexible Storage array and Equallogic array are racked. The other three are dedicated to the HP cluster. Pulled one Enterprise UPS L6-30 near the HP cluster and turned it on. Three PDUs are lit up, but differ from documentation. Change the cabling a bit so that both head node power supplies, one side of the MSA60 power supplies, and all switches plus KVM are on the enterprise UPS. This shall not be interruptable, yea.

• 11/15/10 Cluster arrives. A bit overdue (first ETA was 10/01/10).
