*****We are not 100% compliant with CPIO or MTF any longer and we pulled references to this back around 2006. Our support for multiple volumes and a few other cases broke the standard implementation as do most vendors implementation these days.*****
The process of retrieving files from a NetVault tape can be summarized in 3 steps.
Rewind the tape
Position the tape to the correct point on the tape
Use CPIO to un-archive the files onto your hard disk.
To do this you will need to follow these instructions. The exact syntax of the commands is from NCR UNIX MP-RAS. The steps will be similar for other UNIX platforms, but the switches may differ. We suggest you check the man pages for mt and cpio to check for differences.
Rewinding the Tape
Find out the name of the device driver of the tape device you wish to use; the easiest way of doing this is to check in NetVault. The device driver MUST be that of a non-rewinding device.
IMPORTANT: Please make sure you do NOT have NetVault, or any other process that uses the tape drive, running whilst you perform the following commands; mt will fail as NetVault locks the device.
Enter the following-
mt -f device_name rewind e.g. mt -f /dev/rmt/c1t0d0s0nn rewind
Once this has completed you will now need to move the tape to the correct position.
Positioning the tape
To understand how to do this, you need to know a little about the structure of a CPIO tape that NetVault has used.
To position the tape you w
