Viewing Mirroring Status
Lists the status and configuration of mirroring couplings
mirror_list [ vol=VolName | cg=cgName|<[scope=<cg|volume> ]
[ sync_type=<sync_best_effort|async_interval>]>]
Parameters:
Name Type Description Mandatory Default
sync_type Enumeration List type -
SYNC_BEST_
EFFORT,
ASYNC_
INTERVAL,
or All (if no
parameter is
specified)
N All (if no
parameter is
specified)
scope Enumeration List type - [all
mirrors,] all
volumes, all CGs
N All (if no param is
specified)
vol Object name Local volume
name.
N [none]
cg Object name Local CG name. N [none]
This command shows current configuration and status for the remote mirroring of
volumes or Consistency Groups. Size/part/time to synchronize are unknown if
this is the slave and connection is broken.
The following default parameters are shown:
v Name
v Mirror Type (sync_best_effort, async_interval)
v Mirror Object (CG, Volume)
v Role (Master, Slave)
v Remote System (target name)
v Remote Peer (volume name)
v Active (Yes, No)
v Status (Initializing, Synchronized, Unsynchronized, Consistent, Inconsistent, RPO
OK, RPO Lagging, Change Tracking)
v Link Up (Yes, No)
The following optional parameters can be listed by explicitly specifying the proper
columns:
v Designation (Primary, Secondary)
v Estimated Sync Time (estimated time to synchronization in seconds)
v Size To Synchronize (size to synchronize in MB)
v Operational (Yes, No)
v Sync Progress (sync progress in %)
v Mirror Error (why mirroring is deactivated: No_Error, Configuration_Error,
Secondary_Pool_Exhausted, Master_Pool_Exhausted,
No_Thin_Provisioning_Resources)
