Today was an extended maintenance day, 8am to 5pm.
1. Removal of RFM Cards From End Station Seismic Front End Computers
Cyrus, Jim, Dave: WP5051
The RFM 5565 PCIe cards were removed from the front end computers h1seiex and h1seiey. The procedure was:
- stop user models, then stop iop model
- take system out of Dolphin fabric
- power down computer
- remove all cables from back (one-stop, IRIG-B, RFM, 2xethernet, power)
- pull computer out of rack
- remove 5565 PCIe card
- insert computer into rack, reattach all cables (minus 5565 RFM fiber)
The RFM Switch was reconfigured. The port assignments are as follows (green=unchanged, blue=changed)
| port | before | after |
| 0 | ISC | ISC |
| 1 | SEI | SUS |
| 2 | SUS | empty |
| 3 | empty | empty |
| 4 | empty | empty |
| 5 | empty | empty |
| 6 | empty | empty |
| 7 | UPLINK | UPLINK |
When the seismic FE computer was powered back on, they gliched all the other computers in the fabric (both end statins). We restarted all the user models on h1susex, h1susey, h1iscex and h1iscey.
This closes WP5051
2. Testing New EPICS Gateways
Cyrus: WP5053
Please see Cyrus's alogs.
3. Restart of h1ecatx1
Daniel, Dave:
It was time for h1ecatx1's fortnightly freeze, which it faithfully did at 10am. We rebooted h1ecatx1 and all came back up automatically.
4. Reboot of Guardian Machine
Jamie, Dave:
The h1guardian0 machine was rebooted to test autostartup after reboot and change the NFS client mount options to turn off file attribute caching. Please refer to Jamie's logs for details.
5. Loading Filter Module Files
The following models had partially loaded filter module files. I performed a full COEFF load on: h1isiitmy, h1isiham4, h1isibs, h1isiitmx, h1suspr3, h1susim, h1sussr3, h1susomc, h1susbs, h1lsc, h1asc, h1scimc, h1sushtts
The model h1calcs reported a modified filter file, but this was a latched condition and the filter file was actually identical to the running configuration. I pressed the COEFF load to remove the warning.
The model h1tcscs is reporting a modified filter file, it has new filters for ITMY_CO2_CHILLER_SERVO_GAIN. I have emailed Aidan and Alastair for guidance.
6. Models With Local Modifications Pending SVN Commit
Dave:
Attached is the list of FE code which have local mods relative to the SVN repository
7. Guardian Nodes/MEDM Check
Jamie, Dave:
Nodes which exist but not on OVERVIEW MEDM (temporary nodes): TIDAL_HACK.
Nodes on OVERVIEW MEDM which dont exist (placeholders): IFO, PSL
