Reboot of DAQ system
The h1ldasgw0, h1ldasgw1, h1fw0, h1fw1, h1nds0, h1nds1, h1dc0 and h1broadcast0 computers were powered off and restarted this afternoon.  Updates were applied to the h1ldasgw0 and h1ldasgw1 computers to bring them to the same OS version.  An fsck was performed on h1fw0, which had gone 343 days without a check.  An fsck was also performed on h1nds0 which had gone 272 days without a check.

It is hoped that this maintenance will solve the instability which has caused the frame writers to restart many times per day over the last few days.

The restart of the DAQ performed today also resynced the DAQ to the following modifications:

new ISI models for BSC

new CAL-CS model

new Beckhoff C1-PLC1 INI file (added timing GPS channels)*

* I am still having to hand-edit C1-PLC1 and C1-PLC2 files to remove the duplicated PSL-ERROR_[CODE,FLAG] channels from both.
