Firmware upgrade and downgrade scenarios
You cannot perform a firmware downgrade to a Fabric OS version earlier than 5.2.x, if ADs are
configured in the fabric. Following are special scenarios for director class products only:
• If the primary and secondary CPs are running pre-Fabric OS 5.2.x and are in HA-Sync, if
firmwaredownload is used to upgrade one CP alone (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
show up as an AD-unaware switch in the fabric).
• If the primary and secondary CPs are running Fabric OS 5.2.x and if ADs are configured, any attempt
to downgrade one or both CPs to pre Fabric OS 5.2.x versions will fail. The Admin Domain
configuration must be cleared before you can perform the downgrade (see ”Deleting all user-defined
Admin Domains” on page 164).
