WP 13402 & 13401 DAQD ethernet transition

Jonathan, Erik,

Per WP 13402 the h1daq 0 systems where update to remove the dolphin interconnect and use ethernet.

The work plan is in T2600271.  The basic work flow:

 * Redirect nds queries to h1daqnds1

 * Move the nds2 and ngdd data feeds to the 1 leg.

   * I was unable to get the ngdd services properly running on h1daqkc1.  I will look into this later.

 * power down the systems.

 * remove the dolphin cards, add in the ethernet nics as needed (some systems already had enough nics)

 * reconfigure the networking.

 * update the dns to drop gds0.

 * start and test services.

We moved the h1daqscript0 to a temporary location so that we could mount sw-msr-daqd1.  After we convert the daqstat ioc to a container we will be able to retire that machine.  Pending daqstat updates I have re-enabled the dc0_epics_mirror and added a dc1_epics_mirror so that we can see the gds broadcast crc.  Note even though the system shows a h1daqgds0 and h1daqgds1 those systems are gone, and the broadcast is being done from dc0 and dc1.

I finished off WP 13401 by configuring the frame writers to use the run number server on in the container cluster.  This will be tested at the next daqd restart.

We still need to pull the dolphin switches out of the racks.

Then there is OS upgrades for the daqd systems.
