TDEV with 3200% total written tracks
I have two TDEV that suddenly alerted in Unisphere as 100% full. Upon investigating I found they are showing more tracks written that we have allocated to the TDEV. They are both over 3200% written (see below). Each of the volumes actually has several hundred GB free. How did this happen? How can we fix it? Is there a risk of continuing to use these TDEVs? They are ESX datastores, should be migrate off of them? Any feedback is appreciated.

Hrm.. I was thinking it might be a bug with symcli... But I'm not seeing anything. I'd engage support and let us know what they have to say..

I did open a support case with EMC on this issue. They were able to fix the problem, however, the only explanation I was given was that it was "a new issue we are seeing". I don't know what was done to correct the issue, if it will come back again, or if the data in the TDEV is at risk while it is in this state.
Anyone able to provide more details?

In working with EMC Support I have learned a few things related to this issue:
My main concern was to know if there was a risk to the data. Knowing there is not reduces this problem a minor annoyance in my opinion. Thanks to everyone at EMC that followed up on this issue.
