Restoring the previous firmware version
Use the firmware restore operation to back out of a firmware upgrade. This option works only if
autocommit mode was disabled during the firmware download. On modular switches you must
perform this operation on both management modules.
1. Issue the <firmware> action and specify the <restore> element.
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="412">
<action xmlns:nca="http://tail-f.com/ns/netconf/actions/1.0">
<data>
<firmware xmlns="urn:brocade.com:mgmt:brocade-firmware">
<restore/>
</firmware>
</data>
</action>
</rpc>
<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="412">
<data>
<firmware xmlns="urn:brocade.com:mgmt:brocade-firmware">
<commit>
<result></result>
</commit>
</firmware>
</data>
</rpc-reply>
The switch will reboot and come up with the original firmware.
The firmware commit operation will begin to copy the original firmware from the secondary
partition to the primary partition. When this process completes, both partitions will have the
original firmware. It may take several minutes to complete the operation.
2. Wait until all processes have completed and the switch is fully up and operational.
