There are a few common issues you might run into when using SnapManager with SnapDrive products.

First, you must determine if the issue is related to SnapManager for Oracle or SnapDrive. If the issue is a SnapDrive error, SnapManager for Oracle gives an error message similar to:

SMO-12111: Error executing snapdrive command "<snapdrive command>": <snapdrive error>

The following is an example of a SnapDrive error message where SMO-12111 is the SnapManager error number. The 0001-770 numbering scheme represents SnapDrive for UNIX errors.

"/usr/sbin/snapdrive snap restore -file
