M. Kuniyoshi and A. Horneffer did:
1) Installed the Dell machine
So lofar1a, lofar2a, lofar3a and lofar4a are available from the MPIfR side. The LOFAR side of the network is physically connected but needs to be configured on the lofar-switch.
The port-numbers on the lofar-switch are: lofar1a -> port 9; lofar2a -> port 10; lofar3a -> port 11; lofar4a -> port 12
2) Replaced two "broken" disks in lofar2
3) Checked/replaced LBAs
LBAs with RCUnumber: 8, 12, 44, 54, 68, 72, 74, 78, 82, 86, 92, 130, 138, 148, 150, 152, 164, 178 showed no or low power when checked.
We pulled and re-plugged RCUs 8, 44, 68, 68, and 72, after that RCU was there with reduced power (compared to no power before) and on change in the other RCUs.
We replaced "antenna heads" of LBAs: 44/45 and 86/87 with replacements from ASTRON (old model, used in CS1 or so).
