Got this far (had exact same problem with DLL and had to uninstall/re-install on WFE). Now on verification using "C:\Program Files\NetApp\SnapManager for SharePoint\VaultClient\bin\SMSP2010StorageRBSTool.exe" tool to enable the RBS tool on my content DBs I get "RBS tables not installed". Any ideas?
How are you checking that RBS is not installed? Take a look at the BLOB Provider Settings in SMSP Manager, if it is installed. If it shows installed, you need to enable it on the webapps in the Settings tab there.
That's where I was checking. It says it's uninstalled within the BLOB Provider Settings. Support pointed me to "C:\Program Files\NetApp\SnapManager for SharePoint\VaultClient\bin\SMSP2010StorageRBSTool.exe" and had me run this. I then clicked on "Check" and it said that nothing was installed. I then clicked "Install" and I came up with the following:
Install remote blob storage binaries.
Copy remote blob storage provider DLL to GAC.
Install failed.Could not load file or assembly 'Microsoft.Data.SqlRemoteBlobs, Version=10.50.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
I then uninstalled, rebooted, and reinstalled the agent and it looks like that fixed the issue.
