Issue

SnapCenter unable to enumerate SQL Availability Group.

• SnapCenter interface does not show a SQL Availability Group that exists, even though SnapCenter is able to enumerate disks on each node.  SnapCenter for Windows Plug-In log on individual nodes shows log entries like the following:

    GetPartitionForVolume: return remote partition of remote disk '<Drive Letter>'
    ...
GetHostFileSystem: partition.DiskId = 'Disk ID>', partition.Server = <Remote Server>
    ...
Error: Could not find disk for partition [DiskId: <DiskID>]

    Note: <Remote Server> in these error messages refers to a node other than the local server.

• This may also be accompanied by events like the following in the Windows System Event log:   

DCOM was unable to communicate with the computer <Windows cluster name> using any of the configured protocols; requested by PID <PID> (C:\Program Files\NetApp\SnapCenter\SnapCenter Plug-in for Microsoft SQL Server\SmSqlServiceHost.exe).
