Update config optional parameters

Edit online

Optional parameters follow the update config command and positional parameters.

/CONFIGfile=configfilename
Use the /configfile parameter to specify the name (configfilename) of the IBM Storage Protect Snapshot configuration file that contains the values to use for an update config operation.

The configfilename variable can include a fully qualified path. If the configfilename variable does not include a path, the IBM Storage Protect Snapshot installation directory is used. If the /configfile parameter is not specified, or if the configfilename variable is not specified, the default value is fcmcfg.xml.

If the configfilename variable includes spaces, enclose the entire /configfile parameter entry in double quotation marks. For example: 
/CONFIGfile="c:\Program Files\fcmcfg.xml"
/MOUNTRW=Yes|No

You can mount a read/write copy of your IBM Storage Protect backup so that you can modify the copy without invalidating the backup. You use this option to indicate whether a snapshot backup is mounted as read/write. The default value is as specified in the configuration file with the /MOUNTRW parameter. If a default value is not specified in the configuration file, the default value is No. By specifying the /MOUNTRW option, you override the default value.

The following values are available:
No
Perform a read-only mount operation.
Yes
Perform a read/write mount operation. The behavior of the read/write mount is controlled by the USESNAPOFASNAPTOMount parameter in the configuration file.
  • If USESNAPOFASNAPTOMount is set to No, you can mount only COPY backups as read/write. After mounting, the original backup is modified and can no longer be used as a restore point in future database restore operations (on the VSS Options properties page, the Mount read/write (modifies backup, applies to COPY backups only) check box is selected).
  • If USESNAPOFASNAPTOMount is set to Yes, you can mount both FULL and COPY backup types as read/write (on the VSS Options properties page, the Mount read/write (without modifying backup) check box is selected). In this instance, the backups are not modified and can be used in future restore operations.
    Important:
    This mount option is only available for the following devices:
    • SAN Volume Controller (SVC) devices, which require IBM® System Storage® Support for Microsoft Virtual Disk and Volume Shadow Copy Services version 4.12 or later. Dynamic target allocation is not supported.

    • XIV system devices, which require IBM Storage Accelerate Family Provider for Microsoft Windows Volume Shadow Copy Service version 2.9 or later.

    You must allocate more target volumes on your storage device to accommodate the number of concurrent read/write mounts you want to do. An extra target volume that matches the size of the volume to be mounted, is needed for each concurrent read/write mount of that volume.
/PRESNapshotcmd=cmdstring
The /presnapshotcmd parameter runs a command or script before a snapshot operation begins. You can use this optional parameter to quiesce an application before a snapshot is created. You can then restart the application after the snapshot is started by using the /postsnapshotcmd optional parameter. The cmdstring variable specifies the command to run before the snapshot operation begins. You must specify the fully qualified path name for the command script.
/POSTSNapshotcmd=cmdstring
The /postsnapshotcmd parameter runs a command or script after a snapshot operation ends. You can use this optional parameter to resume the application after the snapshot is created. This parameter is used with the /presnapshotcmd parameter. The cmdstring variable must be a fully qualified path.
