Validating a firmware download

Validating a firmware download
Validate the firmware download by running the following commands: firmwareShow,
firmwareDownloadStatus, nsShow, nsAllShow, and fabricShow.
All of the connected servers, storage devices, 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 Brocade Backbones, this
command displays the firmware loaded on both partitions (primary and secondary) for
both CPs and AP blades. Brocade recommends that you maintain the same firmware
level on both partitions of each CP within the Brocade Backbone. The firmwareShow
command displays the firmware version on each CP.
firmwareDownloadStatus Displays an event log that records the progress and status of events during Fabric OS,
SAS, and SA firmware download. The event log is created by the current
firmwareDownload command and is kept until another firmwareDownload command is
issued. There is a time stamp associated with each event. When downloading SAS or SA
in systems with two control processor (CP) cards, you can only run this command on the
active CP. 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 in to 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 devices connected 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.
