Adding a FlashCopy sub-policy to an IBM Storage Virtualize SLA Policy
The procedures describe how to add a FlashCopy® sub-policy to an IBM® Storage Virtualize SLA Policy.
Procedure
-
Select the source icon and define the recovery point objective to determine the minimum frequency and interval with which backups must be made. In the Frequency field select Minutes, Hourly, Daily, Weekly, or Monthly, then set the interval in the Interval field. The lowest available frequency is five minutes.
Tip: Edits to the frequency and interval of an SLA Policy apply to all associated job schedules.
- In the Target FlashCopy Storage Pool pane select an IBM host destination from the list of available resources as the FlashCopy destination, along with an associated storage pool. If no storage pool is selected, the storage pool with the largest amount of space available is chosen by default. To select the original target destination, select Use Original. Note that you can select multiple storage pools from multiple IBM resources, but only one storage pool is allowed for each node.
-
To enable an Incremental FlashCopy, select Enable Incremental FlashCopy in the Incremental FlashCopy Storage Pool pane. Select an IBM host destination from the list of available resources as the FlashCopy destination, along with an associated storage pool. If no storage pool is selected, the storage pool with the largest amount of space available is chosen by default. To select the original target destination, select Use Original.
If the Enable Incremental FlashCopy option is selected, note that the base FlashCopy will be sent to the destination selected in the Incremental FlashCopy Storage Pool pane. Subsequent incremental FlashCopies will be sent to the destination selected in the Target FlashCopy Storage Pool pane.
Note that the Target FlashCopy Storage Pool must reside on the same storage system as the Incremental FlashCopy Storage Pool.Tip: When editing an existing SLA Policy, Incremental FlashCopy options cannot be altered. -
Click Add FlashCopy. In the Options pane, set the FlashCopy sub-policy options.
- Keep Snapshots
- After a certain number of snapshot instances are created for a resource, older instances are purged from the storage controller. Enter the age of the snapshot instances to purge in the Days field, or the number of instances to keep in the Snapshots field.
- Name
- Enter an optional name to replace the default FlashCopy sub-policy name displayed in IBM Storage Defender Copy Data Management. The default initial name is FlashCopy0.
- FlashCopy Volume Prefix
- Enter an optional label to identify the FlashCopy. This label is added as a prefix to the FlashCopy name created by the job.
Tip: FlashCopy labels must contain only alphanumeric characters and underscores.
- Do not stretch FlashCopy (Enhanced Stretch Cluster Feature)
- Enabling this option will not create stretch FlashCopies. This applies only to volumes that are stretched in storages that have the Enhanced Stretch Cluster feature enabled.
- Enter a name for the new sub-policy (SLA Policy).
- Click Finish. The policy gets created and listed under the All SLA Policies tab.
