Storage Fault Recovery Tracking

This feature tracks over 12 failure-indication parameters such as timeouts, spin-up, and self-test
errors of SCSI drives. You can use these parameters to pinpoint failed storage subsystem
components and to recover from a controller or hard drive failure.

Storage Automatic Reconstruction

This feature automatically reconstructs data to an online spare or to a replaced drive if a drive
fails. To use the reconstruction feature, you must configure the server for drive mirroring or data
guarding. The reconstruction decreases system downtime by allowing rapid recovery to full
system operation if a drive fails.

Network Interface Fault Recovery Tracking

This feature tracks over 20 failure-indication parameters such as alignment errors, lost frames,
and frame copy errors of Ethernet and Token-Ring network interfaces. Fault recovery tracking
decreases network downtime by enabling diagnosis of actual network interface failures.

Memory Fault Recovery Tracking

This feature inspects the operation of the memory subsystem by looking for uncorrectable
memory errors.

ROMPaq Error Recovery Options

From time to time it may be desirable to upgrade the current system ROM. Some reasons for
this upgrade may be as follows:
I
Customer desires ROM upgrade
I
Obtained new SmartStart CD-ROM
I
Desire to upgrade server processors
I
Request from Compaq
The process of upgrading the system ROM is referred to as flashing the ROM. Flashing consists
of using software to replace the current ROM image with a new one through ROMPaq.
If an error such as a power failure occurs during this process, the flash operation does not
complete, causing the ROM image in the server to corrupt. Compaq provides two options for
ROMPaq recovery, depending on the server and circumstances involved.
