Configuring Robotic Controls

Configuring SCSI Robotic Controls

Read this topic if you plan to use a robotic storage device that is controlled through a SCSI

robotic connection. Information on supported SCSI robots (vendor models) can be found

on the VERITAS support web site (see the NetBackup Product > Compatibility area of the

site).

▼ To check for and create the necessary device files

1. Install the SCSI passthru driver as explained in “The SCSI Passthru Driver (ovpass)”

on page 30.

2. Display which SCSI controllers are physically available on your machine by using the

following command:

/usr/sbin/lsdev -C | grep I/O

In the following sample output, SCSI controller 1 (01) has been assigned the logical

identifier scsi0:

scsi0 Available 00-01 SCSI I/O Controller

In the following sample output, FCP SCSI controller 3A-08 has been assigned the

logical identifier fscsi0:

fscsi0 Available 3A-08-01 FC SCSI I/O Controller Protocol Device

3. Display the SCSI device files that have already been created by using the following

command:

/usr/sbin/lsdev -C -s scsi

The example output follows:

hdisk0 Available 00-01-00-0,0 400 MB SCSI Disk Drive

hdisk1 Available 00-01-00-1,0 400 MB SCSI Disk Drive

rmt0 Available 00-01-00-3,0 Other SCSI Tape Drive

This output shows that two disk drives and one tape drive are configured as follows:

◆ hdisk0 is a disk drive at controller 1 (01) and SCSI ID 0 (0,0)

◆ hdisk1 is a disk drive at controller 1 (01) and SCSI ID 1 (1,0)

◆ rmt0 is a tape drive at controller 1 (01) and SCSI ID 3 (3,0)

If the device files for the SCSI robotic control already exist, they appear in the lsdev

output as ovpass0, ovpass1, etc. The output for this example does not show any

ovpass files so you would have to create them as explained in the next step.
