Replacing Multiple Nodes in a Cluster
If the cluster itself is not healthy anymore or if multiple nodes need to be replaced, you must
restore backup files taken around the same time to all of the nodes in the cluster.
Follow these steps to restore backups to multiple nodes in a cluster.
CAUTION: Backup files must be taken around the same time. If the backup file of one node is
out of sync from the others, the restore process will be unsuccessful.
When restoring to multiple nodes, it is critical that you perform the restore process on all nodes
at the same time.
Use the restore local command to restore the cluster from the backup file as you cannot
restore the cluster by using a backup file from another cluster.
1. Log on to the CLI as a system administrator.
2. Run the enable command to enable privileged mode on the CLI.

3. Run the remote restore command to transfer the backup file from the FTP server to the
controller.
ruckus# remote restore {ftp username} {ftp password}
{ftp server address} {(optional) ftp server port} {directory}
