Steps for Upgrading Software With System Loads to
Obtain G06.14 Functionality
b. Shut down any applications using Expand-over-ServerNet connections
between the node and the rest of the cluster.
c. Abort all Expand-over-ServerNet lines on the node for remote nodes in the
cluster. On remote nodes, abort the Expand-over-ServerNet line for the node
receiving the SPRs.
>SCF ABORT LINE $SCxxx
d. Stop the Servernet cluster subsystem:
>SCF STOP SUBSYS $ZZSCL
e. Abort the SNETMON process:
>SCF ABORT PROCESS $ZZKRN.#ZZSCL
f. Abort the SANMAN process:
>SCF ABORT PROCESS $ZZKRN.#ZZSMN
g. Abort all MSGMON processes:
>SCF ABORT PROCESS $ZZKRN.#MSGMON
h. Abort the TSM server process:
>SCF ABORT PROCESS $ZZKRN.#TSM-SRM
i. Run ZPHIRNM to perform the rename step.
j. Restart the TSM server process:
>SCF START PROCESS $ZZKRN.#TSM-SRM
Note. Because of time constraints unique to each production environment, installing
these SPRs sometimes cannot be accomplished all at once for every node in a
cluster. You might need to continue using a star or split-star topology while the SPRs
are applied to some—but not all—nodes. In this scenario, any node to which the
T0569AAE SPR is applied generates a TSM alarm indicating that the node has a
newer version of T0569 than the version running on the cluster switch (T0569AAA or
T0569AAB).
The presence of this alarm can prompt some users to download T0569AAE to the
cluster switches before the SPRs have been applied to all nodes. The repair action for
the alarm warns you not to download T0569AAE to the cluster switches until the SPRs
are applied to all nodes, but some users might not see the warning.
To avoid alarms generated on ServerNet nodes during a migration procedure that
extends over a long period of time, apply all of the preceding SPRs except T0569AAE.
When all of the SPRs except T0569AAE have been applied to all nodes and you are
ready to download T0569AAE to the cluster switches, apply T0569AAE to all nodes.
Note. The TSM Service Application cannot display the Cluster tab for a node on
which $ZZKRN.#ZZSMN (SANMAN) has been aborted.
