Fabric OS 6.x administrator guide 183
Validating firmwareDownload
Validate the firmware download by running the following commands: firmwareShow,
firmwareDownloadStatus, nsShow, nsAllShow, and fabricShow.
NOTE: When you prepared for the firmware download earlier, you issued either the
supportShow or supportSave command. Although you can issue the command again and
compare the output from before and after, it may take up to 30 minutes for the command to execute.
To save time, it is recommended that you use the commands listed below, which are all subsets of
the supportSave output.
All of the connected servers, storage, and switches should be present in the output of these commands. If
there is a discrepancy, it is possible that a device or switch cannot connect to the fabric and further
troubleshooting is necessary.
firmwareShow
Displays the current firmware level on the switch. For directors, this command displays the firmware loaded
on both partitions (primary and secondary) for both CPs and AP blades. HP recommends that you
maintain the same firmware level on both partitions of each CP within the Director.
firmwareDownloadStatus
Displays an event log that records the progress and status of events during the firmwareDownload. The
event log is created by the current firmwareDownload command and is kept until another
firmwareDownload command is issued. There is a timestamp associated with each event. When
downloading Fabric OS, the event logs in the two CPs are synchronized. This command can be run from
either CP.
nsShow
Displays all devices directly connected to the switch that have logged into the name server. Make sure the
number of attached devices after the firmware download is exactly the same as the number of attached
devices prior to the firmware download.
nsAllShow
Displays all connected devices to a fabric. Make sure the number of attached devices after the firmware
download is exactly the same as the number of attached devices prior to the firmware download.
fabricShow
Displays all switches in a fabric. Make sure the number of switches in the fabric after the firmware
download is exactly the same as the number of attached devices prior to the firmware download.
You cannot perform a firmware downgrade from Fabric OS 5.2.0 or later if administrative domains are
configured in the fabric. See ”Managing administrative domains” on page 21 for details.
When the primary and secondary CPs in a 4/256 SAN Director are running pre-Fabric OS 5.2.0 and are
in HA-Sync, and if firmware is downloaded to upgrade only one CP (using the firmwareDownload –s
option), then that CP will run in an AD-unaware mode (AD creation operations will fail and the local switch
will appear as an AD-unaware switch in the fabric).
If primary and secondary CPs are running Fabric OS 5.2.0 or later and if ADs are configured, any attempt
to downgrade one or both CPs to a pre-Fabric OS 5.1.0 version will fail.
See ”Troubleshooting firmwareDownload” on page 183 for exception cases and associated error
messages generated from the preinstallaton check.
