Upgrading or downgrading the firmware on a Brocade FC switch (netapp.com):
https://docs.netapp.com/us-en/ontap-metrocluster/maintain/task_upgrade_or_downgrad_the_firmware_on_a_brocade_fc_switch_mcc.html
There are health checks in the document. Very important is that each disk is seen on both MetroCluster fabrics, because you'll take down one Fabric at a time.
i) Brocade Checks:
- firmwareShow
- fabricShow
- switchShow
- portbuffershow
- porfcfgshow
ii) ONTAP Checks:
- node run -node NODENAME sysconfig -a
- system health alert show
- metrocluster show
- metrocluster check run
- metrocluster check show
- storage switch show
- disk show -disk ADISK -instance
- disk show -fields initiator-side-switch-port
- disk show -errors !'-'
- disk show -container-type broken
- aggr show
- Config Advisor
1) Disable each of the switches in the fabric:
switchCfgPersistentDiasble
- or -
switchDisable
2) Download the desired firmware version:
firmwareDownload
3) Verify the firmware was download and committed to both partitions:
firmwareShow
4) Reboot the switches:
reboot
5) Enable the switches:
switchCfgPersistentEnable
6) Repeat i and ii.
7) Wait 15 minutes before repeating this procedure for the second switch fabric.

Note: We found that we needed /v8.2.3c1_G5_ENTRY in our firmwareDownload (i.e. don't rename to simpler path).

Note: The release.plist file is not listed in the root of the firmware directory (/fw/v8.4.0), but the firmware will use the appropriate release.plist file in the child directory, based on its switch type.
