Step 1: Identify source and Target device needed for performing TimeFinder VP SNAP. Create a device group and add the source and target device to the group. The device which will become a target device must be specified by option ‘-tgt’. Below Screenshot explains how to create a Device group.
Step 2: Create a SNAP VP session between the source and target device. We have to use ‘-vse’ to enable SNAP VP feature in symclone command. While creating a relationship between source and target device we are using logical device name of the device 1E04(source) and 1E05(Target). Step 3: Query the device group vpsnap1, we can see the relationship being created.
Step 4: Now activate the VP Snap sessions. using activate command.
Note: -consistent enable EMC Enginuity Consistency Assist assisted SNAP VP session. When clone sessions are activated this feature will enable consistent point in time copies of the source device.
Step 5: Once the Clone sessions gets activated the Pairs goes in to state copy on write and point in time image gets created.
Percentage of copy sessions can be seen in the symclone query command. Check the copy percentage it shows 1%.
Step 6: We can see the Thin pool details to check how much shared tracks are made will performing the Timefinder VP snap.
Step 7: Terminate the Symclone session to stop the symclone session.
