Verifying your Shared Storage Option configuration
In a Shared Storage Option configuration, a shared drive must have the same logical name (drive name) on all of the NetBackup media servers. If the drive resides in a robotic library, it also must use the same drive number in the library. This section describes some tools you can use to verify your configuration.
How you verify that your configuration is set up correctly depends on your devices and how you configured Shared Storage Option, as follows:
If you have serialized devices, Veritas recommends that you use the Device Configuration Wizard. The wizard verifies your configuration.
If you have non-serialized devices, see the Veritas support site for tech note TECH31764, "Verifying a Shared Storage Option (SSO) Configuration with Non-Serialized Devices. It describes how to verify your configuration.
If you have serialized devices but you did not use the Device Configuration Wizard, use the following procedure to verify your configuration.
The verification procedures use the following NetBackup commands:
On Windows:
install_path\VERITAS\Volmgr\bin\scan install_path\VERITAS\Volmgr\bin\tpconfig
On UNIX/Linux:
usr/openv/volmgr/bin/scan usr/openv/volmgr/bin/tpconfig
In the following example the ADIC robotic library has six drives, but only drives 5 and 6 are configured on this particular host.
Perform the verification on all of the NetBackup servers in your configuration. Ensure that each shared drive has the same logical drive name and same drive number ID on each media server that shares the drive.
To verify a manually-configured Shared Storage Option configuration
- Execute tpconfig -d or tpconfig -dl. For NDMP devices, use tpautoconf -probe -ndmp_host_name host_list.
The output from tpconfig shows the logical names NetBackup assigns to tape drives. The following example shows drive number 5 is named QUANTUM.DLT7000.000 and drive number 6 is named QUANTUM.DLT7000.001:
Id DriveName Type Residence Drive Path Status *************************************************************** 0 QUANTUM.DLT7000.000 dlt TLD(0) DRIVE=5 /dev/st/nh3c0t5l0 UP 1 QUANTUM.DLT.7000.001 dlt TLD(0) DRIVE=6 /dev/st/nh3c0t1l0 UP Currently defined robotics are: TLD(0) robotic path = /dev/sg/h3c0t0l0 EMM server = norway
- Execute the scan command. The scan output shows the robot and the drive properties.
The following is example output:

For each tape drive in the tpconfig output, do the following:
Use the device file name from the tpconfig output to locate the tape drive in the scan output.
Step 1 shows device file pathnames
/dev/st/nh3c0t5l0
and/dev/st/nh3c0t1l0
.Determine the serial number of the drive in the scan output. "Tape" in the device type field identifies a tape drive.
Step 2 shows example scan output shows the following:
The drive
/dev/st/nh3c0t5l0
serial number is PXA37S3261.The drive
/dev/st/nh3c0t1l0
serial number is PXA50S2276.Verify that the serial number for the drive matches the serial number in the output from the robot section of scan. "Changer" in the device type field identifies a robot.
In the previous examples, the serial numbers match.
