RAL Tier1 Operations Report for 5th November 2014
| Review of Issues during the week 29th October to 5th November 2014.
|
- The problem reported last week with the ARC CEs not keeping up processing the jobs has been fixed. A modification to use 'per-job' condor history files has sped this process up. Two of the ARC CEs (arc-ce02 & arc-ce03) have been re-installed with this change.
- There was a reboot of the Teir1 primary router, followed a few minutes later by the secondary, this morning (5th Nov). This was part of the investigations into getting the RIP protocol to work.

| Notable Changes made this last week.
|
- Oracle patches were applied to the 'somnus' database behind the LFC on Thursday (30th Oct).
- The repacking of the CMS data from T10KB to T10KD tapes is progresssing and is now around three-quarters complete.
- Port opened up to allow external Castor WebDav access (requested by LHCb).

| Advanced warning for other interventions
|
| The following items are being discussed and are still to be formally scheduled and announced.
|
- The rollout of the RIP protocol to the Tier1 routers still has to be completed.
- First quarter 2015: Circuit testing of the remaining (i.e. non-UPS) circuits in the machine room.
Listing by category:
- Databases:
- A new database (Oracle RAC) has been set-up to host the Atlas3D database. This is updated from CERN via Oracle GoldenGate.
- Switch LFC/3D to new Database Infrastructure.
- Castor:
- Update Castor headnodes to SL6.
- Fix discrepancies were found in some of the Castor database tables and columns. (The issue has no operational impact.)
- Networking:
- Move switches connecting the 2011 disk servers batches onto the Tier1 mesh network.
- Make routing changes to allow the removal of the UKLight Router.
- Enable the RIP protocol for updating routing tables on the Tier1 routers.
- Fabric
- Migration of data to new T10KD tapes. (Migration of CMS from 'B' to 'D' tapes underway; migration of GEN from 'A' to 'D' tapes to follow.)
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
- There will be circuit testing of the remaining (i.e. non-UPS) circuits in the machine room (Expected first quarter 2015).
