How often should I update my AIX server?

In general:

  • The firmware should be updated twice yearly
  • The AIX level should be updated twice yearly
  • IBM ESA should be installed and configured to “phone home” hardware errors

Performing updates:

  • Complete a full system and data backup
  • Run the current levels through IBM FLRT to check against known issues
  • Install updates in the recommended order: HMC, firmware, AIX level

Strongly Suggested:

  • The system administrator should subscribe to firmware notifications from IBM’s website
  • Firmware should be updated at least:
    • At least twice yearly for regular Release Level scheduled releases
    • Whenever subscription notice advises HIPER fix
    • Whenever new hardware is added
    • Whenever an outage is scheduled, review firmware level and apply updates if convenient
