Check journal volumes

Hi there,

I'm doing an upgrade to a VNX and I want to check if I need to add any more disk to the journal volume but I'm struggling to find any where in the GUI that can show how journal capacity I have left and assuming write traffic doesn't increase (not expected) if I will need to add more.

Any ideas?

Journals are a circular log, its always full. As new point in time copies are created old ones are deleted

Re: Check journal volumes

But not all the journals luns are allocated to protection groups so it hasn't used all the available capacity from the underlying pool right?

Re: Check journal volumes

Not sure I understand your statement. If a Journal is part of an active CG and has been running for a while it is full. If a lun is not assigned to a CG then there is no data on it
