olserver123
olserver129
olserver133

I restarted them on others Xen Server Hosts and service are again available.

Since olserver129 was also involved, it was needed to restart there the Tango database server (DataBaseds) serving the INJ subsystem.
Running also the Tango Starter all INJ Tango process were automatically resumed. At this point it was possible to rerun the corresponding DAQ bridges SL_TempController and Lnfs100

To fix some issues pending after HW failure I needed to restart Network module (Power Recycling on MXL A1,A2) on Chassis 6.

After this operation I needed to restart also:

olserver129
olserver136
olserver137
olserver143
olserver144

Also in this case I have restarted all Tango processes on olserver129 and the corresponding DAQ bridges SL_TempController and Lnfs100.
