Cabinet level unplanned failover of replication sessions

Execute a failover of all NAS server synchronous replication sessions from the remote system to the local system (unplanned failover). Replication sessions of file systems created on the affected NAS servers will also fail over automatically.

Format

/remote/sys -id <value> failover [-force]

Object qualifiers

Qualifier	Description
-id	Type the ID of the remote system from which to failover its NAS server synchronous replication sessions.

Action qualifiers

Qualifier	Description
-force	Specifies whether to skip checking the network connection to the remote system. Required when the network connection is healthy. No values are allowed.

Example

The following command executes a cabinet level unplanned failover replication operation issued for a Unity system:

uemcli /remote/sys -id RS_1 failover

Storage system address: 10.0.0.1
Storage system port: 443
HTTPS connection

ID = RS_1
Operation completed successfully.

NOTE:After an unplanned failover, the NAS servers and file systems on the original source system must be updated to reflect the new status. If there is a large number of NAS servers and file systems, this change may take several minutes to complete. During this period, resume and failback operations of the synchronous replication sessions will not work. It is recommended to wait for all of the updates to complete before running a resume or failback operation. There is no impact to data access while this update is occurring.
