NSS Data migration

Have a question on using NSS 'Creating a RAID 1 mirror to duplicate data'. We are preparing to move our NSS pool from SAN (a) to SAN (b), I know this can be accomplished by using a RAID 1. The question I have is our current NSS pool is 4TB total, consisting of two different LUN's on SAN (a) which currently has a RAID created as we've done this once before. Our first RAID was created to get our data off the local server and onto a SAN, well now I need to move that from old SAN to new SAN.

So do I create a new (new) raid and add the old raid to that then mirror the data to the new disks? Or do I expand or re stripe the existing RAID adding the extra disks to it?

I know this would be easy if it were just one LUN but the multiple LUNs thing along with an existing RAID is proving challenging to find an analogue in the OES documentation.

Thanks for the thoughts!

    That's true, but these days it's actually easier, better and faster to
    use the Pool Move functionality in OES11. Technically it's almost the
    same, just automatically and you can combine and grow pools on the fly.

  • Ashamed to admit it but we are still on OES2 SP3 on the majority of our boxes, including this one. Would it be easier to do an in-place upgrade of the existing (very aged) hardware to OES 11 to take advantage of the pool move feature or are there other options on OES2 for this. Eventually our virtualization push will complete and we will be on OES11 everywhere, this box however is still physical hardware.

    Given that you'll be updating anyways, I'd personally probably do it
    now. But check out OES2015 instead of OES11 (which will be unsupported
    mid next year)

    I have used the pool move functionnality to move 3.5Tb of data from local disk to SAN without any disruption. It's exactly like the Linux pvmove LVM functionnality.

    So i recommend like Massimo a move to OES 11 SP2.
