General Storage Issues
New Issue ESXi 6.0 Update 2 hosts connected to certain storage arrays with a particular version of the firmware might see I/O timeouts and subsequent aborts
When ESXi 6.0 Update 2 hosts connected to certain storage arrays with a particular version of the firmware send requests for SMART data to the storage array, and if the array responds with a PDL error, the PDL response behavior in 6.0 update 2 might result in a condition where these failed commands are continuously retried thereby blocking other commands. This error results in widespread I/O timeouts and subsequent aborts.
Also, the ESXi hosts might take a long time to reconnect to the vCenter Server after reboot or the hosts might go into a Not Responding state in the vCenter Server. Storage-related tasks such as HBA rescan might take a very long time to complete.
Workaround: To resolve this issue, see Knowledge Base article 2133286.

internally we have to update to u2 for security reasons but if the backup is not working than we can't .
