Snapshot for Spectrum Accelerate commands

Edit online

Use this information to learn about commands that are available for Snapshot for Spectrum Accelerate sessions and groups. A snapshot group is a grouping of snapshots of individual volumes in a consistency group at a specific point in time. To issue a command, go to Session Actions > Commands and click the command.

Table 1. Snapshot for Spectrum Accelerate commands
Command	Action
Create Snapshot	Creates a snapshot of the volumes in the session
Refresh States	Refreshes the states of the role pairs that are in the session (if applicable for the session type) and refreshes the state of the session if it is incorrect. This command queries the states of the copy sets on the hardware. You are not required to run this command under typical circumstances; Copy Services Manager refreshes the states of its sessions through multiple means. However, if you discover an inconsistency between Copy Services Manager and the hardware, you can use this command to enable Copy Services Manager to update itself. This command triggers multiple queries on the hardware, which can impact hardware performance. Do not run this command more frequently than every few minutes in each session. This command is not available if the session is in the Defined state.
Restore	Restores the H1 volumes in the session from a set of snapshot volumes. You must have at least one snapshot group to restore from. When you issue this command in the Copy Services Manager graphical user interface (GUI), you are prompted to select the snapshot group.

Table 2. Snapshot for Spectrum Accelerate group commands
Command	Action
Delete	Deletes the snapshot group and all the individual snapshots that are in the group from the session and from the FlashSystem/IBM Spectrum Accelerate. If the deleted snapshot group is the last snapshot group that is associated with the session, the session returns to the Defined state.
Disband	Disbands the snapshot group. When a snapshot group is disbanded, the snapshot group no longer exists. All snapshots in the snapshot group become individual snapshots that are no longer associated to the consistency group or the session. After a snapshot group is disbanded, it is no longer displayed in or managed by Copy Services Manager. If the disbanded snapshot group is the last snapshot group that is associated with the session, the session returns to the Defined state.
Duplicate	Duplicates the snapshot group. When a snapshot group is duplicated, a new snapshot group is created with new snapshots for all volumes that are in the duplicated group. The name of the duplicated snapshot group is generated automatically by the FlashSystem/IBM Spectrum Accelerate.
Lock	Locks a snapshot group. If the snapshot group is locked, write operations to the snapshots that are in the snapshot group are prevented. By default, a snapshot group is locked when it is created. This action is valid only if the snapshot group is unlocked.
Overwrite	Overwrites the snapshot group to reflect the data that is on the H1 volume.
Rename	Renames the snapshot group to a name that you provide. The name can be a maximum of 64 alphanumeric characters.
Restore	Restores the contents of a snapshot group by using another snapshot group in the session. Both of the snapshot groups must contain the same subset of volumes.
Set Priority	Sets the priority in which a snapshot group is deleted. The value can be the number 1 - 4. A value of 1 specifies that the snapshot group is deleted last. A value of 4 specifies that the snapshot group is deleted first.
Unlock	Unlocks a snapshot group. If the snapshot group is unlocked, write operations to the snapshots that are in the snapshot group are enabled and the snapshot group is displayed as modified. This action is valid only if the snapshot group is locked.
