Regarding VPLEX Data Migraion

Hello,

In vplex metro configuration, suppose i have a local device/virtual-volume in cluster-1, and host1 is accessing this virtual-volume via cluster-1, if i migrate this local device to the backend storage in cluster-2(i.e. cross-cluster migration), then:

1. After migration, can host1 still access this virtual-volume ?

2. After migration, which vplex cluster is the new owner of the device and virtual-volume ?

3. After migration, how can another host access the virtual-volume via cluster-2 ?

Thank you.

    Are your hosts cross connected or are they only zoned to their local VPLEX?

    1) yes , this called a remote export. cluster-2 presents the volume through cluster-1. All reads and writes go over the WAN

    2)cluster-2

    3)it is a regular virtual volume so you can put it in a storage view

    Patel,

    Thank you for your replay.

    1. Does the 'global visible' attribute must be set on the virtual volume before the cross-cluster migration ?

    2. Will host1 loss access during the migration ?

    1) no, once you commit the migration it will automatically become global

    2) no
