Symptoms
When a Windows host has a disk mapped to more than 1 mountpoint, the following pop-up error appears when discovering the host:
Error occurred while discovering filesystem(s) on
The Plugin log on the windows host will show:
[] FindDrivesAndMountPoints - Volume Name : \\?\Volume{xxxxx386-ffff-ffff-ffff-a0fdcb46ffff}\[] FindDrivesAndMountPoints - GetVolumePathNamesForVolumeNameW failed with ERROR : 234[] AW_HostAgent::discoverFilesystems - failed to discover volumes
The AppSync Server log will show:
[]->>> Error during file discovery for [] EVENT [GENL_000023]: An error occurred while communicating with the AppSync Host Plug-in. Check to see if agent service is running, and restart if necessary. [] [] 2860e34b-2373-427a-a831-9167474f4452->>> Caught RuntimeException in ServiceIterceptor
Note: Protection should be expected to also fail with a service plan event message like:
Cannot determine the storage type where application xxx resides. Verify if the application is located on a supported EMC storage that has been added to AppSync.
Cause
The disk is mounted to more than 1 mountpoint.The mountvol output in the host folder of emcreports can be used to verify if a disk has more than 1 mountpoint.For the disk seen in the above AppSync plugin message:
Volume Name : \\?\Volume{xxxxx386-ffff-ffff-ffff-a0fdcb46ffff}\
mountvol will show more than one mountpoint, like so:
\\?\Volume{xxxxx386-ffff-ffff-ffff-a0fdcb46ffff}\ C:\mountpoints\MyVol1\ C:\mountpoints\MyVol2\
Resolution
A disk mounted to more than 1 mountpoint is not supported.Reconfigure the host and application so that disks do not have more than 1 mountpoint.
