MSA Cluster Disks do not visible in Windows Server 2008R2

[DiskArray]

We have Windows Server 2008 R2 cluster on MSA2312fc

The shared disks became not visible affter reboot servers. There are disks in Divce Manager, but threre aren't in mapped disk and button  "online" is disabled( see image).

I roll back last windows updates, but it does not help
I used DISKPART SAN -policy=OnlineAll, but it does not help too

Furthermore, I can't expand volume in Stogage Managment Utility.

A button "expand volume" is disabled, although there are free space (see image)

Help please!
