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
