Replication

How do Copy-mode linked targets and NoCopy-mode linked targets behave when a SnapVX unlink operation disassociates the linked target?

  • A Once the copy completes, Copy mode linked targets do not contain a full and usable copy of the source devices.Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.
  • B Once the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.596.583 and later allow access to unlinked targets.
  • C Once the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.
  • D Once the copy completes, Copy mode linked targets will contain a full and usable copy of the source devices.NoCopy mode linked targets will not allow access to unlinked targets.
Explanation

After Copy-mode replication completes, the linked target contains a full, usable point-in-time copy that remains available after unlinking. NoCopy linked targets can be accessed after unlinking when they are fully defined on PowerMaxOS 5978 or HYPERMAX OS 5977.810.184 and later; earlier HYPERMAX OS versions did not qualify this behavior.
