Storing Files from Split Volumes (SPLITVS)
Use the SPLITVS option to store files that are located on the specified
split volume sets. These volumes are also known as mirrored disks.
This provides a form of concurrent, or online backup, because you can:
* Split a volume
* Allow users to access their files
* Perform a backup on the mirrored volume
The SPLITVS option requires:
* The Mirrored Disc product is installed on the system.
* The specified volume sets must be configured as mirrored volumes.
The basic procedure to use split volumes and STORE together is:
1. Request users to close the files on the volume sets that are to be
backed up for a short duration.
2. VSCLOSE the mirrored volume set with the SPLIT option.
3. VSOPEN the volume set. This will open the user and backup sets.
4. Allow users to begin accessing the files again.
5. Issue the store command, using the SPLITVS option. For example:
:STORE @.@.@;*T;SHOW;SPLITVS=my_split_set
6. After the backup has completed, join the split set back together
using the JOINMIRRSET command in VOLUTIL.
For more information on using mirrored disks, see the Mirrored Disk/iX
User's Guide (30349-90003).
NOTE Although the ONVS and SPLITVS options can be used together, a
volume set that is specified for ONVS cannot be specified for
SPLITVS and a volume set that is specified for SPLITVS cannot be
specified for ONVS.
