Conclusion

To benefit from the enhancements, upgrading to firmware version 5.15.3 and KU 108528-24 for Solaris 8 OE and KU 112233-09 for Solaris 9 OE plus patch 116009-01 is required. In a mission critical environment, high availability is achieved by system resiliency, the appropriate configuration, serviceability, and efficient and automated restoration processes. The enhancements made in version 5.15.3 address all of those elements and increase availability, serviceability, and diagnosability of Sun Fire 6800/4810/4800/3800 systems.

TABLE 7 lists the requirements for the various Auto Diagnosis and Recovery Features that are available for the Sun Fire 6800/4800/4810/3800 Systems. Note that SC firmware release 5.15.3 requires the domains use Solaris 8 KU24 or Solaris 9 KU6 with patch 116009-01. For additional patch IDs, refer to TABLE 1.

Standardized messaging, CHS, and AD are powerful tools for users and service providers. AD in combination with DR on Sun Fire 6800/4810/4800/3800 systems greatly increases the availability and decreases scheduled downtime for maintenance.

The proactive actions of the Solaris OE on L2_SRAM events makes the Solaris OE more resilient and increases its availability.
