Preparing an E4SA for PMF or IOMF

CRU Replacement

The E4SA depends on X-fabric or Y-fabric communication from the PMF or IOMF

CRUs in the group of enclosures where the E4SA is installed. The fault tolerance of an

E4SA must be verified prior to replacing a PMF or IOMF CRU.

To verify the fault tolerance of an E4SA, use the SLSA SCF STATUS SAC command

with the DETAIL option to

•

Verify that the Current Access list indicates access to more than one processor.

•

Verify that both the X and Y fabrics are UP.

Note. As of G06.22 and later RVUs, the HP NonStop Open System Management (OSM)

Interface replaces TSM as the system management tool of choice for NonStop systems. For

instructions on using OSM or migrating to OSM, refer to the OSM documentation for your RVU.

Note. For HP NonStop S-series servers, replacing a PMF or IOMF CRU can result in loss of

access to the E4SA unless fault tolerance is ensured.

Note. You use the Replace PMF or Replace IOMF guided replacement procedure to replace a

PMF or IOMF CRU. From your system console, access the procedures as follows:

Start > Programs > Compaq TSM > Guided Replacement Tools > Replace [PMF | IOMF]

If you are replacing a PMF or IOMF CRU in a system running TSM server version T7945AAW

(shipped with G06.12) or earlier, use the Guided Replacement Toolkit (GRT) to replace the

CRU. From your system console, access the GRT as follows:

Start > Programs > Compaq TSM > Guided Replacement Tools > Guided Replacement
