Read This If You Have an EMC Celerra or VNX and OSX Lion Clients!

We’re still getting reports of people having this problem so we are trying to get the word out everywhere that we can.  If you have an EMC Celerra or VNX and there is any chance a user will connect to a CIFS share from an Apple computer running OSX 10.7 (Lion) you should read this EMC Technical Advisory.  Lion can cause the Data Movers to panic and reboot which will initiate a DM failover.

Dear EMC Customer,  

EMC Technical Advisory Regarding Celerra and VNX Storage Arrays   EMC has identified a compatibility issue with the Mac Operating System 10.7 Lion release that will impact the operations of your EMC Celerra or VNX storage system(s).
