Symptoms
When trying to mount and recover an Oracle Database copy, the service plan fails during the "pre-Recover Database" step with the following errors:
The Service Plan events will show:
Recover copy, MILE_000005,<AppSync Server>,Recover copy phase for <DBNAME> completed with errors
Recover copy, GENL_000055,<AppSync Server>,An error occurred while running preRecoverDatabase on host <MOUNTHOST>. Refer xxx.log on the agent host for more details.
Recover copy, GENL_000055,<AppSync Server>,An error occurred while running preRecoverDatabase on host <MOUNTHOST>. Refer xxx.log on the agent host for more details.
The AppSync Server log will show:
ERROR [EJB default - 6] [com.emc.archway.service.sshservice.SshServiceBean] [<AppSync Server>] [] ->>> ACP failed, dumping stderr: Traceback (most recent call last):

The AppSync plugin log on the Mount host, referred to in the Service Plan event to view for more details will show the command being executed, but nothing will follow, like so:
acputil.py[643]:execute() Info:Running command: chown -R 1000:1000 /archives/<DBNAME>/
Cause
The archive log directory was created as /archive/<Filesystem name> when creating the oracle database, but the filesystem name on which it was mounted was /archive. In the AppSync database, the archive destination is saved as /archive/<Filesystem name>, the same name which is provided when creating the database.
When AppSync mounts the copy and tries to recover, it takes the destination from the AppSync database and tries to change the ownership on the destination. Since AppSync mounted it as /archive, /archive/<Filesystem name> does not exist on the mount host. The reason being that a path isn't specified in "path mapping settings" for /archive which will default mount it to /archive on mount host.
The directory /archive/<Filesystem name> doesn t exist on the mount host, but while changing the permission AppSync finds the name from the database.
