How to deallocate WIL on a system with active mirrors?

Hello,

We need to move MirrorView/S write intent log LUNs to another Raid Group but as system has active mirrors I am not able to deallocate WILs. What is correct procedure to remove WILs temporarily?

Even though they are private lun's, are you able to select them and perform a lun migration like a normal lun?

Cant remember if you can migrate a private lun

Nope, I cannot migrate them, I get a message "You cannot migrate a private LUN that is in use by another feature of the storage system".

Silly me, there is an "Use Write Intent Log" checkbox under each mirror item properties, uncheck those and you can deallocate WIL. Problem solved.

Ya, i knew about the check box but was unsure as to what it would do to the mirror once you unchecked it and it was in a sync state.
