Pinned topic v7000 remove from pool is greyed out

‏2013-07-11T20:46:56Z |

why is "remove from pool" greyed out when looking at certain storage pools. seems to be the internal storage only.

i want to move an mdisk to another storage pool.

    shoul i upgrade to 6.3.0.7 or maybe 6.4?

    If you're not yet in production, I'd be tempted to take the jump directly up to the latest: 7.1.0.1

    You can expect there to be much more frequent updates for bug fixes and interop items on the latest codestream, whereas the previous codestreams are effectively in maintenance mode now, with only critical fixes being released.

    When you remove an array mdisk from a storage pool you're actually deleting the array; the member drives return to candidates.  You can then create a new array from them, adding it into another storage pool.

    I'm not sure why the remove from pool option would be greyed out, unless perhaps there isn't enough free capacity in the pool to migrate the data off that array mdisk before doing the delete? (not actually sure if that's something the GUI would check for?)   Could you attach a screenshot and say what version of software you're running?

    Software Version 6.3.0.0 (build 54.6.1111250000)

    basically i want to have one single volume to present to my server. (approx 50TB)

    A couple of thoughts:

    1. As you've cropped the screenshot, I can't see which user you're logged in as.  If you're using a custom user then it might be that user isn't in a group with permissions to perform that sort of configuration change.  In that case, log in as a user that can (e.g. superuser).

    2. The 6.3.0.0 version is coming up on 2 years old.  It would make sense to upgrade to the latest available software level to see if that resolves the problem you're seeing.  It's especially worth upgrading the system at this point if this is a new installation and you're still doing the initial setup; much easier to do it now than when you're in production.  Plus, the software upgrades are free.

    The upgrade matrix is the best starting point:

    http://www.ibm.com/support/docview.wss?uid=ssg1S1003705

    There is also a similar link in the upgrade wizard in the GUI itself.

    upgrade was successful. no longer getting "remove from pool" being greyed out.

     

    how ever i still cant add all my disks to the same storage pool (mdisk group)

     

    i have 24 internal 600gb 10 k sas drives. 

    12 x 2tb 7.2k nl sas in external  enclosure (internal storage)

    16 x 2tb in ds5020 virtualized (exernal storage)

     

    how can i have all these in the same storage pool?

    Dirgkdigs,

    When I look at your drives and it was my environment I would create three storage pools (600GB, 2TB_internal and 2TB_DS5).

    Special reason to put all the mdisks in one storage pool?

    MDisks in a storage pool should have the same performance charactistics. Best is if they are the same raid level and same RPM, and same number of disks in the raid.(The Exception is with SSD disks in an EasyTier setup)

     

    Mixing the 16 2TB disks in the DS5020 and the 12 2TB in the Storwize could be ok, but not optimal performance wise.

     

    Having EasyTier with 3 tiers is required to be able to have SAS and SATA in the same pool - its on the roadmap, and is released for the DS8000 series, where Storwize gets its EasyTier code from - so there is hope that in the future you can do it, but you'll have to wait a bit...

    @TMasteen

     

    reason would be the customer wanted too be able to see one volume when looking at the server. but i think i will talk then out of it,

     

    what raid type would you use. the disks are being used to store video files mainly.
