Mirrorclone creation through RSM

My requirement is as follows ;

 

Day 1 at 9 pm;

1.Create a Mirrorclone of a Vdisk
2. Fracture the Mirror at 9.15 time
3. Immediately Present the fractured Vdisk (mirrorclone) to a host
4. After 4 hrs. time period unpresent the Vdisk from host
5. Re-establish the Mirrorclone.

6. Fracture the Mirror at x time

7. Present the fractured Vdisk (snapclone) to a host

 

Day 2 at 9pm;

1. Resync mirrorclone of a Vdisk ( follow the above steps , before that we need to unpresent that fractured Vdisk )

I read RSM user-guide but could not understand containers concept.

I have created managed set for my Vdisk , but stuck at container level.

Also a sample script would be of immense help ( am trying with help of templates too )

A container is preallocated space for a virtual disk without all the extra metadata. This lets you control the disk group leveling time. Likewise, there's no release of the storage when done, triggering another leveling event. Your best plan is to create a small (1 or 2 G) dummy vdisk, convert it to a container, create another container like it, convert both to dummy vdisks. Flip them back and forth. Get comfortable with containers.

Now: Your schedule looks like:
Setup:

  1. Create a container
  2. Create a Mirrorclone of a Vdisk


Operation:

  1. Fracture the Mirror
  2. Present the mirrorclone to a host
  3. Do work
  4. Unpresent the Vdisk from host
  5. Resync the Mirrorclone


I don't have access to RSM system to look at all the templates. There should be something in there to handle a mirrorclone fracture-present and unpresent-resync.
