▼ To abort reverse resynchronization
The -o reverse_resync_abort option aborts -o reverse_resync_begin, unmounts
the snapshot volumes, and mounts the original volumes back with the file systems that are
configured to use the volume. This operation is only allowed after -o
reverse_resync_begin has been executed and cannot be used after reverse
resynchronization has been committed (-o reverse_resync_commit).
To abort reverse resynchronization, use the -o reverse_resync_begin option as follows:
$ /opt/VRTS/bin/dbed_vmsnap -S ORACLE_SID -f SNAPPLAN \
-o reverse_resync_abort
▼ To commit reverse resynchronization changes
The -o reverse_resync_commit option commits the reverse resynchronization changes
after you have verified that they are acceptable. The operation resynchronizes the original volume
from the data in the snapshot.
To commit the reverse resynchronization changes, use the -o reverse_resync_commit
option as follows:
$ /opt/VRTS/bin/dbed_vmsnap -S ORACLE_SID -f SNAPPLAN \
-o reverse_resync_commit
Then, restart the primary database in ARCHIVELOG mode so that it is ready to take another
snapshot.
If the Oracle authentication password file is used for the database, it needs to be recreated using the
ORAPWD utility after the reverse_resync_commit operation is performed.
For information on resynchronizing the snapshot using the GUI, see “Using the VERITAS Storage
Foundation for Oracle Graphical User Interface” on page 265.
Example
Note The following example is valid only for the online_snapshot mode.
Reverse resynchronization is started on the primary host.
$ /opt/VRTS/bin/dbed_vmsnap -S PROD -f snap1 \
-o reverse_resync_begin
dbed_vmsnap started at 2004-04-02 15:53:45
Database PROD (SID=PROD) is running.
dbed_vmsnap ended at 2004-04-02 15:54:29
Reverse resychronization is aborted on the primary host.
$ /opt/VRTS/bin/dbed_vmsnap -S PROD -f snap1 \
