Define the required number of free volumes for each copy group in the setting file (user.properties).
The required number of free volumes must be defined in the following files.
In the case of non-cluster operation
OS | File Name |
|---|---|
Windows | $INS_DIR\etc\prop\user.properties |
Solaris | /etc/opt/FJSVccm/prop/user.properties |
$INS_DIR means "Program Directory" specified at the AdvancedCopy Manager CCM installation.
In the case of cluster operation
OS | File Name |
|---|---|
Windows | $SHARE_DL:$SHARE_TOP\etc\prop\user.properties |
Solaris | $SHARE_MNT/etc/opt/FJSVccm/user.properties |
$SHARE_DL is the drive letter of the shared disk for AdvancedCopy Manager CCM shared data.
$SHARE_TOP is the directory that contains "Environment Directory" and "Work Directory" of the shared disk for AdvancedCopy Manager CCM shared data.
$SHARE_MNT is the mount point of the shared disk for AdvancedCopy Manager CCM shared data.
If the above files do not exist, they must be created.
In the above files, define the copy group name and the required number of free volumes.
Item Name | Explanation |
|---|---|
acsnap.freePair.copyGroupName | The name of the copy group is defined in the copyGroupName section. Define the copy group names displayed with the acgroup list command using the correct uppercase and lowercase letters. Copy groups for which this item is not defined and copy groups for which an invalid value is set are considered to be a value of 0. |
Example
The following is an example of defining the required number of free volumes for copy group "grp1" as "1" and the required number of free volumes for copy group "grp2" as "2" in the "user.properties" file.
acsnap.freePair.grp1=1 acsnap.freePair.grp2=2

For an overview of snap generation processing when the acsnap start command is executed with the required number of free volumes set, refer to "2.6.2 Logic for Selection of Copy Pair to Start SnapOPC+".
