Preparing a G4SA for Processor

Replacement

Replacing a processor can result in loss of access to the G4SA associated with the

system unless fault tolerance is ensured. A G4SA depends on X-fabric or Y-fabric

communication from the processors in the group of enclosures with which the G4SA is

associated.

1. Before replacing a processor, use the SLSA SCF STATUS SAC command with the

DETAIL option to verify the associated G4SA’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.
