Preparing a GESA for PMF or IOMF
CRU Replacement
A GESA depends on X-fabric or Y-fabric communication from the PMF or IOMF CRUs
in the group of enclosures where the GESA is installed.
For NonStop S-series servers, replacing a PMF or IOMF CRU can result in loss of
access to the GESA unless fault tolerance is ensured.
1. Before replacing a PMF or IOMF CRU, use the SLSA SCF STATUS SAC
command with the DETAIL option to verify the associated GESA’s fault tolerance:
a. Verify that the Current Access list indicates access to more than one
processor as shown in the following example.
b. Verify that both the X and Y fabrics are UP as shown in the following example.
