Configuration Table Parameters and Values

The format of the configuration file is similar to a Windows .inf file. It has sections and key value pairs. The section names are the names inside the square brackets, and the key value pairs are in KEY=VALUE format with one pair on each line. All the entries in the configuration file are case-sensitive.

The key value pairs are under the volumes to which they belong, and the section names are the names of those volumes. Two examples of the syntax of the section name in the caagperf.cfg file are [/] or [/export/home]. If a volume has multiple entries, the behavior of the client agent is undefined.

The key value pairs are used to set parameters for the volume under which they belong. By default, all options are disabled. If no special processing is needed for a volume, that volume should not be in the caagperf.cfg file.

The keys and their values are described in the following table:

Key

Value

DOSNAP

Enables the Snapshot feature on a volume. The value should be BACKUP, meaning that a snapshot should be taken during the backup operation.

SNAPSHOTBUFFER

Specifies the buffer used for storing original data before it is overwritten in the snapped volume. The value should be a file name or partition. The file can be a file or a directory from a different volume.

The value of this field depends on the file system type. For the advanced version of VxFS or Online JFS, the value is the name of an empty partition. For UFS, the value is a file name, a directory name, or a partition name.

DOUBIO

Enables the Direct I/O feature on a volume. Values are BACKUP, RESTORE, and BACKUP_RESTORE. The value of this field depends on your backup or restore requirements.
