Procedures for Preparing ServerNet/FX Adapters for
PMF CRU Replacement
Task 5: Bring up the connections affected by the replacement of the PMF
CRU
Verify the status of the ServerNet fabric that was affected by the PMF CRU
replacement. Use the SCF Kernel subsystem STATUS SERVERNET command as
follows:
SCF> STATUS SERVERNET $ZSNET
Make sure that all the affected fabrics came up in the processor that had its PMF CRU
replaced and in the companion processor. For example, if a PMF CRU located in slot
50 was the one replaced, verify that the X path is up in the processor located in slot 50
and in slot 55.
Bring the fabric up manually if it is still in a down state. The only way the FOX
connections can be recovered is if the ServerNet fabric connection is in an up state.
To bring up the connections affected by the replacement of the PMF CRU, use one of
the following procedures based on your specific system configurations:
If the primary FOX monitor process is running in any other enclosure than the PMF
CRU that was replaced and if software supporting the ServerNet/FX Path Management
Facility is running on the same system where the PMF CRU was replaced, the paths
from the companion processor in the same enclosure as the PMF CRU that was
replaced must be restarted.
When a PMF CRU located in slot 50 is replaced, all X paths from the processor
located in slot 55 will remain down after the PMF CRU is replaced.
To recover all down paths from the processor located in slot 55, issue the following
ServerNet/FX adapter subsystem command to the processor located in slot 55 of
the enclosure (local processor):
SCF> START PATH $ZZFOX.local processor, TO \*.*, SUB ALL
When a PMF CRU located in slot 55 is replaced, all Y paths from the processor
located in slot 50 will remain down after the PMF CRU is replaced.
To recover all down paths from the processor located in slot 50, issue the following
ServerNet/FX adapter subsystem command to the processor located in slot 50 of
the enclosure (local processor):
SCF> START PATH $ZZFOX.local processor, TO \*.*, SUB ALL
If the primary FOX monitor process is running in the same enclosure as the PMF CRU
that was replaced or if software supporting the ServerNet/FX Path Management
Facility is not running on the same system where the PMF CRU was replaced, the
connection between the LBU (logical interface to the ServerNet/FX adapter) and the
