Without a System Load to Obtain G06.12
detailed steps, refer to Using the TSM Service Application to Download the
ServerNet II Switch Firmware or Configuration on page 4-99.
4. Use the Firmware Update action of the TSM Service Application to download the
T0569AAA M6770 firmware file to the nearest X-fabric cluster switch. For detailed
steps, refer to Using the TSM Service Application to Download the ServerNet II
Switch Firmware or Configuration on page 4-99.
5. Use the TSM Service Application to perform a hard reset of the nearest X-fabric
cluster switch:
a. From the Cluster tab, click the plus (+) sign next to the External ServerNet X
Fabric resource to display the Switch resource.
b. Right-click the Switch resource, and select Actions. The Actions dialog box
appears.
c. In the Actions dialog box, choose Hard Reset, and click Perform Action.
6. Use the TSM Service Application to verify the operation of the X-fabric cluster
switch.
7. Use the SCF STATUS SUBNET $ZZSCL command on all nodes to verify that
direct ServerNet connectivity has been restored on the X fabric:
>SCF STATUS SUBNET $ZZSCL
Note. Note the following considerations for downloading the T0569AAA configuration:
•
Downloading the configuration disrupts ServerNet communications across the X-fabric
cluster switch.
•
The T0569AAA configuration does not support Configuration 2 (0x10001). If the
cluster switch uses Configuration 2, you must change the configuration tag to
Configuration 1 (0x10000) in order to download the T0569AAA configuration. The
guided procedure allows you to change the configuration tag.
Note. Direct ServerNet connectivity is automatically restored after an interval of
approximately 50 seconds times the number of nodes in the cluster (25 seconds for nodes
running G06.14 or a later G-series RVU). For faster (but manual) recovery of ServerNet
connectivity, use the SCF START SERVERNET \REMOTE.$ZSNET.FABRIC.* command
on all affected nodes after you have verified by using the TSM Service Application that the
X-fabric cluster switch is operational.
The START SERVERNET command works only for nodes running G06.12 or a later
G-series RVU. For nodes running G06.09 through G06.11, the following commands can be
used:
SCF STOP SUBSYS $ZZSCL
SCF START SUBSYS $ZZSCL
Stopping and restarting the ServerNet cluster subsystem destroys and restarts
interprocessor connectivity between the node that receives the commands and all other
nodes over both external fabrics.
