[edit] Cray J932SE System at 757 Labs

[edit] Specs

  • 32 vector processors
  • VME chassis (not gigaring yet)
  • Sun Sparcstation 5 SWS workstation on hand
  • Missing hard drives
  • Have Unicos 10.0.0.1 and 10.0.0.2
  • Have Dynaweb and other documentation

[edit] Notes

  • September 2011
    • More progress in getting system online
    • Modified j90initial.setup script
      • Decrease 2 minute wait
    • Had to run j90inutial.setup many times
      • Issues creating ios0/ios1/ios2/ios3 files
        • rlogin/telnet to IOS 1/2/3 , use mc and iostart commands on each after load
        • j90initial.setup script is only talking to ios0, others aren't running when it runs
      • Used info from cray-cyber re: missing file (will post here)
    • Forgot about jconfig, ran that again on new install
    • Moved all drives to bottom disk box, now ios0 sees all 4
      • Had an error with there not being enough space, it was only seeing 2 drives
    • Still isn't coming online
    • CIT software fails on step 3, network pre-install script portion
      • It's doing an rlogin to ios0, control-A to switch to Unicos
      • Unicos has no response, it's not there or running.
    • SWS workstation is missing the bootsys utility, along with others
      • It looks like bootsys is used to load a ram image on the Cray from
      • Unicos_exe dir on the CD media. Then CIT configs the network and
      • from there the disks can be mkfs'ed and base system xferred.
    • No sign of bootsys utility on the Unicos 10.0.0.1 or 10.0.0.2 CDs.
      • j90help utility mentions a J90 Install CD for the SWS
        • THIS IS INCORRECT! j90root.setup generates the boot_ram file
        • Re-ran it and it worked!!
      • j90root.setup has an error in it?
        • config file is short 1 memory board. This might be cause of error
        • from IOS about MEMORY= statement in config file
        • Remove the sed -e "s;:;;" line.
          • It removes one : from the memory board list, which is used later in the
          • script to figure out how many memory boards there are. This throws it off.


  • Feb 2011
    • Cray graciously donated 6 4GB SCSI disks!
    • Drives arrived and were installed


  • August 2010
    • Sparcstation boots
    • IOS will load
    • Unicos install is a no-go
    • System doesn't see hard drives
    • Germans say their 318 disks are Seagate WD's
      • Disks have different firmware
      • Need a utility to duplicate firmware
        • Asked on Seagate forums [forum post]
        • Asked on HDDGuru
  • February 2010
    • VME SCSI CARDs = Interphase
  • January 2010
    • Jody redid the chassis so the drive chassis is on the right
    • Power drop is 2 x 25 amps @ 208 for main cabinet
    • Power drop is 1 x ?? amps @ 208 for sub cabinet
    • Not sure if it's 208 or 220 or 240 or what. Space is 3 phase
    • Is there an issue with each cabinet sitting on different legs?
    • UPS for unit would probably be really expensive. APC Matrix 5000 probably too small.
