EnableSnap
Command:
EnableSnap { DcsSnap#}
Description:
Enable a snapshot relationship if you want to create a logical image of data that is instantly available for use, and is independent of the source volume from which it was created. Once the snapshot relationship is enabled, you can perform additional snapshot activities on it.
Arguments:
DcsSnap# : A value that represents the snapshot relationship number.
Return Value:
0: success.
-1: failure. Call the GetLastErrors command for extended error code information.
Error Codes:
DCSPIT_ERROR_INVALID_PARAMETERS: There is a potential version mismatch between API and driver, the snapshot relationship is already enabled, or the source or destination volume is already active in a conflicting Snapshot role.
DCSPIT_ERROR_DEVICE_DOES_NOT_EXIST: The snapshot relationship does not exist.
DCSPIT_ERROR_NO_SUCH_DEVICE: Either the configured snapshot volume does not exist, or Snapshot has not yet been established on the disk partition.
