sql server clustering : Splitting Data and Logs

I am having difficulty setting up my disks on my SQL 2005 cluster. I have a
data disk and log disk for each instance (3) but when trying to setup a new
DB, when I try to choose the log drive it does not appear.

I remember choosing a location during setup for data files and this is what
is displayed.

How do I go about splitting my data and log files for each database instance?

Thanks,

I have set the dependencies on the logs disk resource but still can't see it
under the database properties in SSMS?

I have restarted cluster services on both nodes - is there anything else I
have missed?

Thanks,
Neil Paddock.

You must add the disks to the resource group for your SQL Server AND make
the SQL service dependant on them.

Once you have this configured, SQL will display and allow these disk devices
to be used for database file storage.

You can use SSMS to change the default location once the dependencies are
set correctly.

Neil,

ok I think you did that wrong, add the disks that are not showing up as
dedencies to the SQL server resource, you will need to stop the SQL service
first then go to properties of the SQL Server service and modify the
dependencies tab so that each of the missing drives shows up under Resource
Dependencies for the SQL Server Properties.

That should do the trick.

Use the following to see if SQL instance is actually seeing the drives.

select * from ::fn_servershareddrives()

Neil,

how many physical disk resources do you have in your group ?

Hi John,

Still not with you - When I go to modify the dependencies of the SQL
service, I see the following:

Dependencies:
CONT_DATA (Data disk)
SQL Network Name

Available Resources:
Analysis Services
SQL IP Address 1
SQL Server Fulltext

The Log disk is listed under the same cluster resource as the data disk.

Thanks,
Neil.
