WP7161: Dan, Dave:

Today we are upgrading the second frame writer system (h1fw1/h1ldasgw1) from SATABOY-RAID to E18-RAID.

Remember that we had upgraded the fw0 system back on 18th October, that system has been accumulating full and second trend data since that time. The default NDS is h1nds1, so this change was transparent to the control room.

Today's change will be more intrusive to the control room. In preparation for the upgrade, I have reconfigured h1nds1 (default NDS) to mount h1ldasgw0:/frames-0 file system. The nds was down for about 10 minutes while this was done.

We will now power down h1fw1 and h1ldasgw1, disconnect the two SATA-BOYS, connect the E-18. Build a file system on the E-18. Connect one of the SATA-BOYS and build a file system on it customized to its function as a raw-minute-trend archive server.

h1nds0 (guardian's NDS) is unaffected by today's work.
