I have a problem in a MSCS when add more than 9 disk in the nodes.
When add 10 disk, the disk management is more slow and all operations whit disks spend a lot of time. The access to disk needs about 5 minutes for get a Backup of SQL (only for open the browser), and each operation needs 5 minutes too. Access to diskpart, access to disk management, change de node of SQL... needs this 5 minutes and if the number of disk increases the wait increases too.
The Storage is in EVA HP P6500.
In Exchange 2010 with DAG I have the same problem.
It's possible because the O.S are in Spanish??? How I can make the access faster? With 9 disks the access is fine but one disk marks the difference.
