  • Upgrade luci.luci/lucix.luci from CentOS 7 to Alma Linux 9. Testing progress available at LUCI install procedures.
  • Network: S.Hooper previously expressed interest in an overall reconfiguration of the LUCI private address space. It might be useful to have LUCI1, LUCI2, and Lab configured to have separate netmasks. Currently, they are at intervals of 10 (,,, which is not netmask-able.

ENG Summer Shutdown Task Request

MODS (Jerry Mason email 2022/06/21

  • mods2: the RAID 1 mirror array seems to break every time the machine is rebooted, so this time I am rebuilding it using drives sda and sdc, and leaving sdb as the spare. The sdb drive should be permanently replaced – sometime. A summer shutdown task, maybe?
  • mods1: I can’t see the “correct” mods1 machine on the eight port Raritan; the one I do see on the Raritan is labeled “down” and grayed out; I assume that is the unbootable mods1 that was mistakenly used as mods1 last week, and that needs to be returned to OSU for repair or replacement. I would like to make sure that the working mods1 is in good health, but I can’t until it is connected to the Raritan.
  • It would also be good to get the 16-port Raritan installed and configured in the rack eventually, so that all of the MODS computers are visible. Another summer shutdown task, maybe.


  • Synology
    • Firmware update mountain/Tucson
    • Need LeRoy on standby for mountain in case we get a reprise of the split-brain
    • PSU swap from Tucson to Mountain
    • Complete depopulation of old Tucson Synology, move pieces to the mountain.
  • Core switch upgrade
    • Last year was a mess with AO folks.
    • Request 2 days for no network in the plan
  • Mountain DNS change and upgrade
    • will probably happen before SSD
  • Obs stations reconfiguration, replacement
    • 5 stations at each Tucson, Mountain
    • removing the argos station, no reply from Linc Nirvana yet ...
    • wasted unused SSD space.. see IT8902. grow /dev/sdb to full extent, /dev/sda unused also has 256GB, come up with a scheme.
  • DIMM new card?
  • AllSky new fiber extender ?
  • dms mountain/tucson swap - physical at mountain, vm at tucson - best timing in Aug
  • iLocater PEPSI wrap (to be lead by Al Conrad/Mtn/ENG? not IT)


  • Create, test, and release new lib-telemetry RPMs, now that we know that the HDF5 patch is only needed for 1.10.0 <= HDF5 version <= 1.10.3. Completed
  • migrate IMS/AHS to alma9
  • upgrade DMS to f38


  • reconciliate anemometers hw on sx/dx to use the same baud rate (ideally, if h/w allows, not very critical)
  • spare adsec commissioning
  • AO cabinet switches replacement ?


  • New AZCAM s/w update
    • Need new DNS entries for new azcamserver virtual machine.
    • Test each new AGW connection individually.
    • add an SSD task, maybe best during Telescope restart.

Recurring tasks
