Upgrading Software Without System Loads to

3. On all nodes, 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
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.
5. On the downloader node:
a. Use the Firmware Update action of the TSM Service Application to download
the T0569AAB 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 T0569AAB 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.
This scenario does not change the ServerNet node number range for the
cluster switch.
c. Use the TSM Service Application to verify that the X-fabric cluster switch is
operational.
d. Use the SCF STATUS SUBNET $ZZSCL command on all nodes to verify that
direct ServerNet connectivity has been restored on the X fabric.
Note. Using the SCF STATUS SUBNET $ZZSCL command 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.
Note. Downloading the firmware and configuration disrupts ServerNet connectivity
through the X-fabric cluster switch temporarily.
