VIOS partition with a target SAS drive (add tape to client)

Step 1:

$ lsdev -type tape

name status description
rmt0 Available SAS 4mm Tape Drive

To list all devices of type "tape" that can be used as backing devices, type

$ lsdev -type tape4vtd

name status description
rmt0 Available SAS 4mm Tape Drive

To export a physical tape drive to a client as a virtual tape drive.

step 2:

$ mkvdev -vdev rmt0 -vadapter vhost0

vttape0 Available

To list all virtual target tape devices

step 3:

$ lsdev -type tape -virtual

vttape0 Available Virtual Target Device - Tape

step 4:

$ lsmap -all -type tape

SVSA Physloc Client Partition ID
-------------- ------------------------- -------------------

Backing device rmt0
Physloc U789C.001.DQD2684-P1-C4-T1-L900-L0

step 5:

Run cfgmgr on client partition to configure the virtual tape drive

Note: If the physical tape drive is currently used as a backing device and you want to use it locally on the VIOS (i.e to create a backupios), the Virtual Target Device (VTD) must be removed or set in a Defined state first, or you can also choose to remove the backing device

Example:

To remove VTD, vttape0, type
$ rmvdev -vtd vttape0

To put VTD, vttape0, in a Defined state, type
$ rmdev -dev vttape0 -ucfg

To remove the backing device
$ rmvdev -vdev rmt0
