d. Use the TSM Service Application to perform a hard reset of the nearest X-
fabric cluster switch:
1. From the Cluster tab, click the plus (+) sign next to the External ServerNet
X Fabric resource to display the Switch resource.
2. Right-click the Switch resource and select Actions. The Actions dialog box
appears.
3. In the Actions dialog box, choose Hard Reset, and click Perform Action.
e. Use the TSM Service Application to verify the operation of the X-fabric cluster
switch.
f. Use SCF to make sure that direct ServerNet communication is possible on
both fabrics between all nodes connected to the cluster switches:
>SCF STATUS SUBNET $ZZSCL, PROBLEMS
g. Use the Configuration Update action of the TSM Service Application to
download the T0569AAA M6770CL configuration to the nearest Y-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.
h. Use the Firmware Update action of the TSM Service Application to download
the T0569AAA M6770 firmware file to the nearest Y-fabric cluster switch. For
Note. The T0294AAG (or a superseding SPR) must be applied in order for you to use
the PROBLEMS option.
If the PROBLEMS option is not available, use the SCF STATUS SUBNET $ZZSCL
command on all nodes. SCF STATUS SUBNET $ZZSCL requires T0294AAA or a
superseding SPR. If remote passwords are configured, you can issue the SCF
STATUS SUBNET $ZZSCL command for a remote node (for example, \REMOTE)
from the local node as follows:
SCF STATUS SUBNET \REMOTE.$ZZSCL
This command eliminates the need to establish a logon window for each node.
Note. Note the following considerations for downloading the T0569AAA configuration:
•
Downloading the configuration disrupts ServerNet communications across the Y-
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 in order to download the T0569AAA configuration. The guided
procedure allows you to change the configuration tag.
