RAL Tier1 Operations Report for 1st April 2015
| Review of Issues during the fortnight 18th March to 1st April 2015. |
- There were problems with the argus server that affected batch work on wed 18th March. This as fixed following a callout in the evening.
- A further investigation into the primary Tier1 router on the morning of Thursday 19th March failed to fix the problem whereby the router fails after a few minutes in service.
- A problem was found and fixed that caused gridmap file updates to fail.
| 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. |
- gfal2 and davix rpms are in the process of being updated across the worker nodes.

| Advanced warning for other interventions |
| The following items are being discussed and are still to be formally scheduled and announced. |
- Separate some non-Tier1 services off our network so as to be able to more easily investigate the router problems.
- Update Castor to 2.1-14-15 (Proposed date - Wednesday 8th April).
Listing by category:
- Databases:
- Switch LFC/3D to new Database Infrastructure.
- Update to Oracle 11.2.0.4

- Update SRMs to new version (includes updating to SL6).
- Fix discrepancies found in some of the Castor database tables and columns. (The issue has no operational impact.)
- Networking:
- Resolve problems with primary Tier1 Router
- Enable the RIP protocol for updating routing tables on the Tier1 routers. (Install patch to Router software).
- Increase bandwidth of the link from the Tier1 into the RAL internal site network to 40Gbit.
- Make routing changes to allow the removal of the UKLight Router.
- Fabric
