Replace a Failed Primary Management Center (Unsuccessful Backup)

Two management centers - FMC1 and FMC2 are part of a high availability pair. FMC1 is the primary and FMC2 is the secondary. This task describes the steps to replace a failed primary management center -FMC1 when data backup from the primary is unsuccessful.

Procedure

Step 1

Contact Support to request a replacement for a failed management center - FMC1.

Step 2

When the primary management center - FMC1 fails, access the web interface of the secondary management center - FMC2 and switch peers. For more information, see Switching Peers in the Management Center High Availability Pair.

This promotes the secondary management center - FMC2 to active.

You can use FMC2 as the active management center until the primary management center - FMC1 is replaced.

Caution

Do not break management center High Availability from FMC2, since licenses that were synced to FMC2 from FMC1 (before failure ), will be removed from FMC2 and you will be unable to perform any deploy actions from FMC2.

Step 3

Reimage the replacement management center with the same software version as FMC1.

Step 4

Install required management center patches, geolocation database (GeoDB) updates, vulnerability database (VDB) updates and system software updates to match FMC2.

Step 5

Deregister one of the management centers - FMC2 from the Cisco Smart Software Manager. For more information, see Deregister the Management Center.

Deregistering management center from the Cisco Smart Software Manager removes the Management Center from your virtual account. All license entitlements associated with the management center release back to your virtual account. After deregistration, the management center enters Enforcement mode where no update or changes on licensed features are allowed.

Step 6

Access the web interface of the secondary management center - FMC2 and break management center high availability. For more information, see Disabling Management Center High Availability. When prompted to select an option for handling managed devices, choose Manage registered devices from this console.

As a result, licenses that were synced to the secondary management center- FMC2, will be removed and you cannot perform deployment activities from FMC2.

Step 7

Re-establish management center high availability, by setting up the management center - FMC2 as the primary and management center - FMC1 as the secondary. For more information , see Establishing Management Center High Availability.

Step 8

Register a Smart License to the primary management center - FMC2. For more information see Register the Management Center with the Smart Software Manager.

What to do next

High availability has now been re-established and the primary and the secondary management centers will now work as expected.
