Adding and Deleting Storage Devices

After you install ISM, you can add up to four storage devices. When you first install the ISM software, you must add the devices that you want to use as storage devices.

To add a new tape drive or optical disk drive to the ISM server

Create a new device as follows:
```
ism_add -device device_path -type type
```
1. Specify the complete pathname of the storage device that is connected to the ISM server.
  UNIX Only
  For ISM servers on UNIX computers, the format is as follows:
```
/dev/rmt/0mbn
```
  End of UNIX Only
  
  Windows Only
  For ISM servers on Windows, the format is as follows:
```
\\.\Tape0 
```
  End of Windows Only
2. Specify the device type.
The Media Types column in Table 4 shows the valid device types for tape and optical drives.
To verify that you created the new device, issue the command:
```
ism_show -devices
```
By default, the new storage device is enabled for use in backup and restore operations.

To add a filesystem as a storage device to the ISM server

On the ISM server, create a new directory or folder where you want to store the data.
Be sure to create it on media with free space that is larger than the size of your backup. It is recommended that you create the file-type device on a different drive from the one that contains your operating system so that you do not run out of disk space.
Create a new device as follows:
```
ism_add -device device_path -type file
```
1. Specify the pathname of the directory or folder that you just created.
2. Specify a device type of file.
To verify that you created the new device, issue the command:
```
ism_show -devices
```
By default, the new storage device is enabled for use in backup and restore operations.

You cannot include file-type volumes used with a file-type device in a pool that includes other types of volumes. ISM does not allow volumes of other types to be recycled or added to a pool of file-type volumes. For details on how ISM uses volume pools, see How ISM Uses Volume Pools.

To delete a storage device

Remove the storage device as follows:
```
ism_rm -device device_path
```
To verify that the device was deleted, issue the command:
```
ism_show -devices
```
