Hello
Can someone please help me with the following question :)
I am not an SQL DB (more Windows OS, AD, PowerShell etc)
We have a mix of Windows 2008 R2 and 2012, we then have a mix of SQL 2008 R2 and 2012.
The above are running as guests on VMWare 5.1
The storage for these guests is C: and D: drive where the master database is are VMDK's
The S: and L: drives are iSCSI attached LUNs, (where the user databases and logs are)
all the storage is NetApp filers (VMDK's and LUN's)
The issue is when a NetApp failsover occures (e.g. failing over from one to the other head during maintence to upgrade the head for example) the Mater database becomes detached and the databases go down.
We have been tunning iSCSI and related time out for example and check patching levels, the SQL seems very sensative to event a short time space where it cannot access the disk holding its master database.
Question: Therefore does anyone know of a documents listing various Windows Registry keys or SQL settings etc. to make SQL more tollorant to backend disk failover and short term backend disk storage glitches.
Thanks
Ernie
