EVA4400 Unpopulate Disk

[PProcopi]

I have EVA4400 with Firmware 11200000. Last time i change a failed hard disk. I add the disk in Disk Group but few hours later in Command View ( Installed in Windows Server ) i saw the disk as Unpopulate.  After 3 days the disk appear normal .

Also another issue with EVA is that Command View "hung" for 4-5 hours and then return in normal. The EVA works OK just i can;t manage it.

Have in mind that when EVA upgraded to Firmware 11200000, Management Board on EVA not upgraded to latest Command View. Instead Command View installed on Windows Server.

Any idea
