Steps for Upgrading Software Without System Loads
to Obtain G06.14 Functionality
q. Use the TSM Service Application to check the ServerNet cluster status. For 
information about using TSM, refer to Section 5, Managing a ServerNet 
Cluster.
3. Use SCF to make sure direct ServerNet communication is possible on both fabrics 
between all nodes connected to the cluster switches: 
>SCF STATUS SUBNET $ZZSCL, PROBLEMS 
4. Select a node whose system console can be used to download the ServerNet II 
Switch firmware and configuration. This will be the downloader node.
If you are upgrading a cluster that uses a split-star topology, you must select two 
downloader nodes: one for the X1/Y1 cluster switches and one for the X2/Y2 
cluster switches. (You cannot download firmware or a configuration across a four-
lane link to a remote cluster switch.) 
5. On the X1/Y1 downloader node:
a. Use the Firmware Update action of the TSM Service Application to download 
the T0569AAE firmware from the server to the 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. 
b. Use the Configuration Update action of the TSM Service Application to 
download the T0569AAE configuration from the server to the 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.
Note. In order to use the PROBLEMS option, T0294AAG (or a superseding SPR) must be 
applied.
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.
Caution. All nodes attached to a cluster switch whose firmware and configuration will be 
updated with T0569AAB or T0569AAE must be running a version of the operating system that 
is compatible with the T0569 SPR to be downloaded. Any nodes that do not meet these 
requirements might experience permanent loss of Expand traffic across the cluster switch 
when the new firmware and configuration are loaded on the cluster switch. Ta bl e 4- 32
 on 
page 4-99 describes the NonStop Kernel requirements for ServerNet nodes connected to 
cluster switches that will be updated.
Note. In cluster switches running the T0569AAA firmware and configuration 
preloaded at the factory, the fault LED can turn on when firmware is downloaded. This 
is normal, and the fault LED will turn off when the new configuration is loaded.
