Virtual TapeServer 8.4 Configuration Guide

Attaching External Devices after Initial Deployment

You can attach an external tape device, such as a tape drive or robotic library, to VTS after initial

deployment. You can then export to physical tapes loaded in the device if migration, stacked export,

or tape-to-tape export is enabled.

To use an external disk drive for vault and pool storage, see "Adding vaults on external storage

devices" on page 15.

To add an external tape device to the VTS server

Requires the View/Manage Configuration and Halt and Reboot TapeServer access rights

1. If a virtual tape drive (VTD) is already defined on the port, complete the following steps to

remove the drive:

a. Delete the VTD that uses the target port. Click Configuration > Virtual Devices on the

navigation pane. If necessary, log in. Then, click next to the VTD you want to

remove. A dialog box is displayed indicating that VTD operations will be interrupted if

you modify the VTD. Click OK to confirm the deletion.

b. Change the system limits for the target port.

c. In the MANAGE PORT CONFIGURATION section of the Configure Virtual Devices page,

select physical from the drop-down list that corresponds to the target port and then

click Submit. Confirm that you want to reboot the server.

2. Power down the VTS server and then cable the physical tape device (through the SCSI

converter as necessary) to the VTS server. Then, power on the physical tape device and SCSI

converter. Refer to the VTS Quick Start Guide for hardware diagrams and information.

3. Power on the VTS server.

4. To confirm that the physical tape device was created and is communicating with the operating

system, go to the Linux text console and enter the following command:

sg_map –x

Here is an example of the output from this command:

/dev/sg0 0 0 3 0 1 /dev/nst0

/dev/sg1 6 0 0 0 5 /dev/scd0

/dev/sg2 6 0 0 1 5 /dev/scd1
