This page shows the details of a Replication on a Hitachi Block storage device.

Note: Replication records must be manually removed here after they have been removed from the data flow. Records for replications currently in an active data flow cannot be torn down or deleted.
Figure. Replication Details
Control Description
Rename Secondary LDEVs Opens the Hitachi Block Rename Secondary LDEVs Dialog to enable renaming of LDEVs using a fixed string and/or substitution variables.
Mount Opens the Hitachi Block Snapshot or Replication Mount Wizard to guide you through mounting the Replication.
Note: The unmount operation can take several minutes to complete.
Unmount Unmounts the selected replication. The export is deleted.
Note: The unmount operation can take several minutes to complete.
Pause Enabled only if one or more Replications are selected. Pauses the Replication.

Opens the following dialog:

Selecting this option will pause the replication and make the S-VOLs writable without needing to contact the primary array or storage proxy to allow continuation from a primary site failure.

Note: This option is only relevant for remote replications – if selected for local replication it will be ignored.
Resume Resumes a paused Replication.
Swap Opens the Hitachi Block Replication Swap Wizard to guide you through swapping the Replication direction.
Unsuspend If a Swap operation cannot be completed due to a P-VOL or data link fault between the primary and secondary device, then the replication will enter the SSWS state (suspended for swapping) indicating that the swap is not yet complete. Unsuspend enables the replication process to be re-established once the cause has been rectified.
Add to additional Host Groups Opens the Hitachi Block Add to Host Groups Dialog to enable LDEVs to be added to host groups in addition to the default ProtectorProvisionedHostGroup used by Protector. A job is queued to perform the operation on the array and this may take some time to complete.
Remove from Host Groups Opens the Hitachi Block Remove from Host Groups Dialog to enable LDEVs to be removed from host groups, including the default ProtectorProvisionedHostGroup used by Protector. A job is queued to perform the operation on the array and this may take some time to complete.
Tag Modifies the tags of an existing object from the either the inventory screen or the details screen of the object.
Dissociate
  • Dissociates a replication from Protector.
  • Removes the selected replication(s) from Protector including state information such as direction and mount location.
  • The replication remains active on the hardware device(s).
  • The word 'DISSOCIATE' must be entered before the command is executed.
CAUTION:
Dissociating a replication removes all knowledge of the replication from Protector, including state information such as direction and mount location.
Force GAD IO Mode Initiates the forcing of the GAD IO mode. The word ‘FORCE’ must be entered, and the storage array which you want to be the writable before the command is executed. The side selected will be made writable and if the Array and the Storage Proxy for the other side of the GAD is contactable it will be place into a Blocked state.
Note: This feature can only be used on a paused or failed GAD replication. This can not be used on an Active Active GAD replication.
Remove DRU Protection

If the replication was created with DRU protection and the protection lock duration has expired, this will remove the protection.

A confirmation dialog opens to confirm the action of DRU Protection Removal. Clicking confirm will remove the DRU protection lock.
Teardown Initiates the teardown of the replication. The word 'TEARDOWN' must be entered before the command is executed.
Delete Deletes the replication record from Protector. The replication is also removed from the block storage device.
Summary Identifies the hardware storage device, application, policy, DRU Protection Type, DRU Settings Lock Expiry, and general status.
State Indicates the status of the replication.
Nodes Indicates the Nodes involved in the replication. Opens the Node Details for the node selected.
