Qualified Functionality in ClusterStor 3.2

Functions supported or not supported in ClusterStor software version 3.2

  • Support for Live Updates from ClusterStor 3.1 to 3.2
    • The filesystem could remain online during the update
      • Users should expect performance degradation during the update
    • Batch update method (with the filesystem down) is supported
    • OEM server updates are now supported
    Note: Live updates from 3.0 to 3.2 are NOT supported. For these updates, the filesystem must be taken down.
  • Improved GOBI update script
    • Reduced time to apply the firmware
    • Automatic retries for failed actions (up to 3 times)
    • Ability to control timeouts for each operation (transfer firmware, select firmware for activation, activate firmware) as well as timeout for retry operation. Cray does not recommend changing the timeouts below the default settings as it may affect stability of the update process. Default timeouts:
      • transfer: 3 seconds
      • select: 3 seconds
      • activate: 60 seconds
      • retry: 10 seconds
  • Encrypted Data at Rest Key Management
  • The format of the system's serial number changed to use Cray Asset Name
    • For production systems the format of the serial number in the installation YAML file must match Cray Asset Name (e.g., 12345678)
    • For non-production (lab) systems the format of the serial number remains the same (e.g., CSSD12345678)
    • cscli csinfo output on production systems now reflects the format change:
