dataontap module - using powershell to invoke abort on all active snapmirror sessions

[thaddad]

I have  a script that can quiesce or abort on a single relationship  (Invoke-NcSnapmirrorAbort...or Quiesce)

My goal is to have  is to Invoke_ .... Abort on all volumes (active replication sessions).  Can I supply a global value  to  DESTINATION to acccomplish this...or do i have to run the abort against each relationship?  Or how? thanks

We want to automate a "kill" for all active sessions!

Heres the command syntax for abort ..hope you can read it.

Hi,

Here's a script that using the private REST CLI to enumerate all snapmirror relationships that are in a transferring state and abort them.
