Updating the Firmware and Configuration
In general, alarms are not created during the rest period. You can ignore any alarms
that occur during these operations.
Soft Reset and Hard Reset
You must perform a soft reset of the ServerNet II Switch subcomponent after a
firmware download. After a configuration download, you must perform a hard reset.
The guided procedure includes the soft reset and gives you the option to perform the
hard reset function, as required. The following table compares the soft and hard reset
functions:
T0569AAA Firmware and Configuration Files
The ServerNet II Switch firmware and configuration files provided with G06.09, G06.10,
and G06.11 are empty. For this reason, HP strongly recommends that you apply SPR
T0569AAA to all ServerNet nodes running G06.09 through G06.11.
T0569AAA provides the firmware and configuration files (see Table 4-31
on page 4-98)
equivalent to the files that HP preloaded on the cluster switches during shipments for
G06.09 through G06.11. If T0569AAA is not present on all nodes and a problem occurs
with a cluster switch during a software upgrade, you cannot fall back by downloading
the original firmware and configuration files to the cluster switch.
The T0569AAA configuration (M6770CL) defines that all switch ports are by default
enabled for ServerNet pass-through data traffic. This behavior is acceptable for a star
topology cluster supporting up to eight ServerNet nodes and using one cluster switch
per fabric. However, enabling the ports by default is not allowed for the split-star or tri-
star topologies. For these topologies, ports can be enabled only after neighborhood
checks have been performed to validate that the cluster is correctly cabled and
configured.
Before updating a cluster switch to newer firmware, you must apply the T0569AAA
SPR. The procedures for upgrading software later in this section include this step.
Note. TSM alarms are not suppressed when sensitive operations are performed on cluster
switches using SCF commands.
Soft Reset
•
Must be used after a firmware update.
•
Restarts the firmware but not the router-2 ASIC.
•
Does not disrupt pass-through ServerNet traffic.
Hard Reset
•
Must be used after a configuration update.
•
Restarts the firmware and the router-2 ASIC.
•
Is equivalent to a power-on reset.
•
Disrupts pass-through ServerNet traffic.
•
Is implemented automatically by the T0569AAA firmware after a
firmware update. This defect in the T0569AAA firmware has been
corrected in T0569AAB.
