PPME and SWAP SPACE

Hi All,

As per my understanding I cant PPME, if the disk are used for SWAP space. Corrct me if am Wrong.

Suppose  my server having 5 EMC disk used for swap space and I want to migrated using PPME, then how can i proceed with it ?

remove the swap from EMC disk,
Migrate  all disk using  PPME
reconfigure swap on  new EMC drives.

Will the above ll be a good solution ?if not, please suggest me !

(Here am migrating from clariion to symmetrix )

    Hi Dynamox,

    Thank you for the response. I am aware  of that. i see  that in  PP 5.3 release notes. . But just want to make sure that  PP 5.5 also wont support  SWAP and boot disk.

    Now am looking for a solution,  How can i proceed , if I have SWAP space in EMc disk.

    remove the swap from EMC disk,
    Migrate  all disk using  PPME
    reconfigure swap on  new EMC drives.

    Do you have any better solution than the above. . I am sure if i remove swap space, then it may hit performance..(incase if the swap space utilisation is high.

    Karl, thanks for the suggestion. I guess that would be the best option..  Hope we don't  feel any performance hit  after  deactivate the SWAP space on source  as we already added the new SWAP from destination array..

    Thanks again

    Hi Saul,

    it's been a long time.

    I hope that you are doing fine.

    What is the type of the O.S.? Windows, Linux?

    Saul i am not sure, i have to investigate it, but i think that PPME does not support migrating paging or swap devices.

    Let me check it for sure.

    Host Copy

    PowerPath Migration Enabler Host Copy is a host-based migration tool that uses host

    resources to move data nondisruptively from a source to a target. Host Copy supports the

    following:

    ◆ Migrations to and from a device managed by PowerPath (boot and swap devices are

    not supported)

    ◆ Migrations to and from virtually provisioned devices (thin devices)

    ◆ Migrations to and from encrypted LUNs

    Saul unfortunately i don't know may things about Solaris and AIX but i can ask and let you know.

    As far as i "know" HPUX, we never migrated SWAP devices.

    And boot devices we were used Host Mirror Copy or TF/Clone in Symmetrix.

    We provide always new devices fro SWAP!!!

    And the same we have done for ESXs as well.

    same restriction applies to PPME 5.5. You will need to rely on array based tools and schedule downtime. Shutdown the host and either use SanCopy to push to Symm or Open Replicator to pull from Clariion. If you have SanCopy enabler that would be my choice.
