Defining a Disk Storage Pool Volume

To create a disk storage pool volume, complete the following fields and then click Finish, or click Cancel to end this task.

Note: To achieve faster write speed to disk storage-pool volumes on a Tivoli Storage Manager OS/400 PASE server, issue the following command from an OS/400 command prompt once after each volume is created:
CHGATR OBJ('/path/stgpoolfile') ATR(*MAINSTGOPT) VALUE(*MINIMIZE)
where path is the relative path to the storage pool volume (stgpoolfile). If in your configuration you specified automatically-defined volumes and you want to take advantage of faster write speeds, you must identify those particular volumes and issue the command against each one.

Storage Pool Name

The name of the storage pool to which the volume will be assigned is displayed.

Volume Name

Enter the name of the storage pool volume. This name is required. The name is dependent on the operating system.

Operating System Name Requirements
AIX

Linux

PASE

Regular file: Enter a file name with the fully qualified path name or the path name relative to the current working directory. Example: /server/stgvol.001

Logical volume: Enter the name in the format /dev/rxxx, where xxx is the logical volume name.

HP-UX Regular file: Enter a file name with the fully qualified path name or the path name relative to the current working directory. Example: /server/stgvol.001

Raw logical volume: Enter a character mode special file in the format /dev/vg/rxxx, where vg is the volume group name and xxx is the logical volume name. Example: /dev/groupa/rdsa

Attention: The server cannot always detect if data already exists on a raw logical volume. Existing data can be destroyed if you define a storage pool volume to that logical volume.

Sun Solaris Regular file: Enter a file name with the fully qualified path name or the path name relative to the current working directory. Example: /server/stgvol.001

Raw partition: Enter a symbolic link to a character special file in the format /dev/.../rdsk/.../fn, where /... is zero or more directories and fn is the file name. Example: /dev/rdsk/clt34ds6

Note: Raw partitions generally provide the best performance.

Attention: The server cannot always detect if data already exists on a raw partition. Existing data can be destroyed if you define a storage pool volume to that partition.

MVS, OS/390, z/OS Enter the name of a volume that has been allocated and formatted. Example: SERVER.STORAGE.POOL003
Windows Enter a file name with the fully qualified path name or the path name relative to the current working directory.

Example: c:\program files\tivoli\tsm\server\data3.dsm

VM Enter a name of a disk that has been formatted using CMS FORMAT. 

Example: 301

Media Access Status

Select how client nodes and server processes (such as migration) can access files in the storage pool volume. The default is Readwrite.

Readwrite Specifies that client nodes and server processes can read from and write to files stored on the volume.
Readonly Specifies that client nodes and server processes can only read files stored on the volume.
Unavailable Specifies that neither client nodes nor server processes can access files stored on the volume. You cannot vary the volume online.

Format Size

Enter the size of the volume, in megabytes, to be formatted and defined.

This field does not apply to servers running on MVS, OS/390, or z/OS operating systems.

Wait for Completion

Select whether to wait for the server to complete processing this command in the foreground. The default is No.

Yes The server processes this command in the foreground.
No The server processes this command in the background.
