System Name: IP: Notes:
chg-ewx EWX Development VM, temporarily moved to zippy after some issues Libby 11:23, 14 September 2015 (PDT)

Moved back to ubu after ubu stabilized.

chg-ewxtest IP: Test VM for EWX, not usually on
chg-rcmrd IP: Windows Server 2012 VM for testing and documentation to deploy to RCMRD.


  • Ubu was moved from EH 1609 to the sixth floor EH ERI server room on November 23rd, 2015. It's domain was also changed from geog.ucsb.edu to chg.ucsb.edu at that time.
  • Used ubu shelf spare on zippy, July 7th, 2014.
  • Graphics card failure on April 6th, 2015. All systems wedged and during reboot ubu got stuck (at BIOS stage 91) until graphics card was pulled ( mtc tried pulling RAM and a few other things first to no effect). mtc will handle the RMA for the graphics card.
    • Update on GPU: Same BIOS issue with new graphics card. Libby 12:37, 4 May 2015 (PDT)
  • 32 TB /raidb added on September 10th, 2015 using ZFS filesystem. Libby 11:23, 14 September 2015 (PDT)
  • A number of CPUs wedged over the weekend, rebooted by Aaron via IPMI, some load strangeness but otherwise operating. Libby 11:26, 14 September 2015 (PDT)
    • On September 15th, OIT notified CHG that a Bitcoin miner (minerd) was detected on ubu, thus explaining the intense load issue that was not showing up via the top command.
      • Ubu was infected via an IPMI exploit - though ACLs had been requested on August 16th, 2015, they had not been put in place due to a communication failure. ACLs in place as of mid-September, 2015.
      • Once it was determined that ubu was indeed rooted, ERI moved to take ubu down and do a complete reinstall, taking the opportunity to upgrade ubu to CentOS7 and gnisv2.
