La commande 'mirror_list' permet d'afficher la liste des miroirs de la baie et les informations rattachées.

# mirror_list

Name                 Mirror Type       Mirror Object   Role   Remote System             Remote Peer           Active   Status         Link Up  

h6_testvg01_R   sync_best_effort   Volume  Master XIV 78 Prod salle F   h6_testvg01_J   yes Synchronized

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:

NameTypeDescriptionMandatoryDefault
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.

Les différents champs affichés par la commande :

  • Name
  • Mirror Type (sync_best_effort, async_interval)
  • Mirror Object (CG, Volume)
  • Role (Master, Slave)
  • Remote System (target name)
  • Remote Peer (volume name)
  • Active (Yes, No)
  • Status (Initializing, Synchronized, Unsynchronized, Consistent, Inconsistent, RPO OK, RPO Lagging, Change Tracking)
  • Link Up (Yes, No)

The following optional parameters can be listed by explicitly specifying the proper columns:

  • Designation (Primary, Secondary)
  • Estimated Sync Time (estimated time to synchronization in seconds)
  • Size To Synchronize (size to synchronize in MB)
  • Operational (Yes, No)
  • Sync Progress (sync progress in %)
  • Mirror Error (why mirroring is deactivated: No_Error, Configuration_Error, Secondary_Pool_Exhausted, Master_Pool_Exhausted, No_Thin_Provisioning_Resources)
  • Schedule Name (schedule name)
  • Last replicated Snapshot Time (yyyy-mm-dd hh:mm:ss)
  • Specified RPO (value in h:mm:ss format)
The following deactivation reasons can be read from the output list (available only in XML output format):
  • INACTIVE_USER - No_Error
  • INACTIVE_SECONDARY_LOCKED - Secondary_Pool_Exhausted
  • INACTIVE_POOL_EXHAUSTED - Master_Pool_Exhausted
  • INACTIVE_VOL_SIZE_MISMATCH - Remote_And_Local_Volume_Size_Mismatch
  • INACTIVE_CONS_GROUP_MEMBERSHIP_MISMATCH - Cons_Group_Membership_Mismatch
  • INACTIVE_POSSIBLE_VOL_SIZE_MISMATCH - Possible_Remote_And_Local_Volume_Size_Mismatch
  • INACTIVE_POSSIBLE_CONS_GROUP_MEMBERSHIP_MISMATCH - Possible_Cons_Group_Membership_Mismatch
  • INACTIVE_THIN_PROVISIONING - No_Thin_Provisioning_Resources
  • INACTIVE_PEER_STATUS_MISMATCH - Peer_Status_Mismatch
  • INACTIVE_UPGRADE - Temporarily_Deactivated_For_Upgrade
