Pinned topic Is VDISK migration supported for Volumes in a "GM with Change Volumes"?

‏2012-05-24T15:01:38Z |
Hi -

I was wondering if sone could help?

I haven't been able to find any documentation surrounding a supported procedure for "migrating a vdisk in a GM change Volume Relationship to another storage pool (mdiskgrp)".

I understand the Master and Change Volumes need to be in the same pool.

Questions:
1. Is VDISK migration to the another pool (MDISKGRP) supported for volumes (vdisks) in a "Global Mirror with Change Volumes"?
2. What is the procedure to migrate the vdisk to another POOL (MDISKGRP) for volumes in a GM with Change Volumes?

Any help or direction you can provide is much appreciated

Best regards,

Evan

    Hi,
    I am wondering were did you find the info that change volumes need to be in the same mdiskgrp? Would be interesting to see this statement.

    What I found is according to http://www.redbooks.ibm.com/abstracts/sg247933.html?Open page 592 these are the requirements for change volumes

    Change Volume requirements
    Follow these rules for the Change Volume:
    - The Change Volume can be a thin-provisioned volume.
    - It must be the same size as the primary and secondary volumes.
    - The Change Volume must be in the same I/O Group as the primary and secondary
    volumes.
    - It cannot be used for the user’s remote copy or FlashCopy mappings.
    - You must have a Change Volume for both the primary and secondary volumes.
    - You cannot manipulate it like a normal FlashCopy mapping.

    My apologies, I meant to say the same I/O group

    Thank-you for your reply.

    Much Appreicated,
