NOTE
You can use the firmwareCleanInstall command in cases where you need to return to the defaults
and multiple levels of Fabric OS versions need to be skipped. This command does not require HA in
sync. The least or minimum version that can be downloaded using the firmwareCleanInstall
command is Fabric OS 6.4.0. Starting with Fabric OS 7.4.0, the firmwareCleanInstall command is
available to both root and admin users.
ATTENTION
When you run the firmwareCleanInstall command, the storage is reformatted and all data and code
including the configuration file in the CP are removed. Only the configuration storage in the WWN
card, such as IP addresses, is preserved. Do not run the firmwareCleanInstall command on both
CPs at the same time as the CPs reboot independently of each other.
NOTE
During nondisruptive firmware download or disruptive firmware download with the commit option,
firmware commit should start as a part of firmware download after the HA state gets in sync. Firmware
commit can also be triggered when any failure happens, such as sync failure and standby reboot
failure during firmware download before the HA state gets in sync.
Displaying the HA redundancy status
To display the switch uptime and CP blades redundancy settings, use the haRedundancy --show
command.
