RAL Tier1 Operations Report for 4th February 2015
Review of Issues during the week 28th January to 4th February 2015. |
- A test was carried on the problematic router during Thursday afternoon (22nd) when it failed within a few minutes of taking over as the master. A manual flip back to the other router was then carried out. This caused a 5-minute break in network connectivity to the Tier1.
- There was a problem with the LHCb SRMs yesterday (Tuesday 27th Jan). Some processes didn't re-connect to the databases following required reboots to pick up security updates.
Resolved Disk Server Issues |
- None
Current operational status and issues |
- We are running with a single router connecting the Tier1 network to the site network, rather than a resilient pair.
Ongoing Disk Server Issues |
- None
Notable Changes made this last week. |
- The safety checking of the electrical power circuits in the machine room has been completed.
- The migration of all data off T10000A & B media has been completed.
- On Friday (23rd Jan) the FTS3 srevice was upgraded to version 3.2.31.
- On Monday (26th Jan) some redundant Castor stager schemas were cleaned up.

Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
- Investigate problems on the primary Tier1 router. Discussions with the vendor are ongoing.
- Track appropriate security updates.
- Move of connection for CERN Backup link on Tuesday 3rd Feb.
Listing by category:
- Databases:
- Application of Oracle PSU patches to database systems.
- A new database (Oracle RAC) has been set-up to host the Atlas 3D database. This is updated from CERN via Oracle GoldenGate. This system is yet to be brought into use. (Currently Atlas 3D/Frontier still uses the OGMA datase system, although this was also changed to update from CERN using Oracle Golden Gate.)
- Switch LFC/3D to new Database Infrastructure.
- Update to Oracle 11.2.0.4
- Castor:
- Update SRMs to new version (includes updating to SL6).
- Fix discrepancies were found in some of the Castor database tables and columns. (The issue has no operational impact.)
- Update Castor to 2.1-14-latest.
- Networking:
- Resolve problems with primary Tier1 Router
- 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. (Install patch to Router software).
- Fabric
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
Entries in GOC DB starting since the last report.
Key: Atlas HC = Atlas HammerCloud (Queue ANALY_RAL_SL6, Template 508); CMS HC = CMS HammerCloud
