“The parameter is incorrect” when adding cluster disk resources as mount points
I have been building large SQL clusters as part of a large Microsoft infrastructure deployment the last week adn came across the following error. I thought I would share the simple solution. When trying to add a cluster disk resource as a mount point you get an error stating “The parameter is incorrect”. Note that I have already added all the disks to the failover cluster manager as resources (and the disks where online).
It turns out to assign these disk the simple solution is just to place the disk resources into maintenance mode before trying to assign the mount points. To do this in failover cluster manager – select “Storage“. Find the disk you want to assign. Right click the disk and selec “More Actions” – > “Turn on maintnenace for this disk“.
