Preparing a TRSA for PMF or
IOMF CRU Replacement
The TRSA depends on X-fabric or Y-fabric communication from the PMF or IOMF
CRUs in the group of enclosures where the TRSA is installed. The fault tolerance of an
TRSA must be verified prior to replacing a PMF or IOMF CRU.
To verify the fault tolerance of an TRSA, 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.
The following display is an example of that returned by the STATUS SAC command
with the DETAIL option.
Note. For Compaq NonStop™ Himalaya S-series servers, replacing a PMF or IOMF CRU
can result in loss of access to the TRSA unless fault tolerance is ensured.
Note. The Guided Replacement Toolkit (GRT) is now the only supported method for replacing
a PMF or IOMF CRU. To access the GRT, start from the toolbar located on the desktop of your
TSM console. Navigate to the menus as follows:
START > Programs > TSM Client > Guided Replacement Tools > Guided Replacement
Toolkit
For information about the GRT, refer to the Guided Replacement Toolkit User’s Guide located
in the Help menu of the GRT.
