Chapter 9 Cisco SME Troubleshooting
Cluster Recovery Scenarios
Note The Cisco SME cluster configuration for an offline switch must be done using the CLI. Cisco SME
cluster configuration for an online switch can be done using Fabric Manager or the CLI.
Deleting an Offline Switch from a Cisco SME Cluster
To delete an offline switch when one or more switches are offline and the master switch is online, use
these procedures.
On the offline switch (for example, switch2), shut down the cluster by performing this task:
Note Repeat the procedure for every offline switch.
On the cluster master switch, delete the offline switch (for example, switch2) by performing this task:
On the offline switch (switch2), delete the cluster by performing this task:
Note Delete the cluster on every offline switch that was shut down in the first procedure.
Deleting a Cisco SME Cluster with One or More Offline Switches while the Master Switch is Online
To delete a Cisco SME cluster that includes one or more offline switches and online master switch, use
these procedures.
Caution Do not remove a cluster master switch from a cluster and then try to revive the cluster on an offline
switch. Since the offline switch was not part of the operational cluster, the cluster master may have
progressed beyond what is in the offline switch’s state. Deleting the cluster master and reviving the
cluster on an offline switch can lead to data corruption.
