HyperSwap / Mirrored Voulmes (live, realtime)

  • 1.  HyperSwap / Mirrored Voulmes (live, realtime)

    Posted Mon October 03, 2022 09:17 AM

    Hello,

    we got 2 new 5035 FC Storages. We done the initial setup on the first one and add the second to the first. Now we have a two-node cluster.

    We create a Pool0 with all SSDs in System1 (Raid6) and a Pool1 with all SSDs in System2.

    We download and start the IP Quorum App successful (connect).

    Our goal is to create a realtime/live mirrored voulmes.

     

    I create a mirrored Volume. Copy0 to Pool0 and Copy2 to Pool1.

    In the details of this volume I see the volume is striped ?!? So if I power off enclosure-1 I got the waring "Powering off the configuration node temporarily logs you out of the management GUI and the host will not be able to access 1 volume."

     

    May be I misunderstand mirrored Volumes ?!?

     

    Now we add the Remote Copy license and modify the system Topology to HyperSwap. Now we got 3 sites. 1=enclosure1, 2=enclosure2, 3=quorum

    I create a HyperSwap Volume in Pool0 and Pool1. In the details of the volume, I found again "Virtualization type: Striped".

    And same behavior, If I shutdown enclosure1 I got the message "Powering off the configuration node temporarily logs you out of the management GUI and the host will not be able to access 1 volume."

    If I shutdown I enclosure2 I got the warning "Powering off the control enclosure will impact system performance." And the volume is online.

     

     

    But we want the volume to remain accessible on both enclosure.

    Please help !
