When installing NetVault on an HP-UX system, a post script runs to create NetVault specific device files for each SCSI or Fibre device. The script creates device files using mknod, and gets the minor number using a combination of ioscan and lsdev output.
When troubleshooting device issues, it may be required to test the rmt device file for a drive using OS tools such as mt.
The nvscsi device file name contains the minor number to the device.
For example, the minor number for the device /dev/nvscsi/SCTL3302 is 0x330200.
To match an rmt device file to this nvscsi device file, the simplest way is to perform a directory listing of /dev/rmt

The rmt device file /dev/rmt/3m matches the nvscsi device file /dev/nvscsi/SCTL3302.
