Gives you links for the Virtual Vault documentation.
The relevant section in the Administrator's Reference goes like this:
-----------------------------
To boot from the tape, ensure that the backup tape is in the drive, and follow the appropriate procedure for your system to boot from tape.
The root volume group is recovered as it was when the backup was performed, including all kernel customizations, patches, software, sensitivity labels, and so forth. The tape is not a byte-by-byte copy.
bbtcreate produces an install tape that contains all the information needed to re-install the system. The tape contains an install kernel, information for the install configuration program about how to configure
the root volume group, and a full backup of the filesystems in the root volume group.
As the default, the cold install configuration program prompts the user and waits for an answer indefinitely if it finds that the target disk has valid data. Higher values of -t specify the number of seconds that the
cold install configuration program pauses before starting the restore process without user interaction. If the user interrupts the restore process, the program invokes the configuration user interface to allow the
user to select the disk or disks that will be part of the root volume group. We recommend using the default value (0) of the -t option when creating your BBT. Leaving the cold install configuration program to
restore unattended could overwrite disks containing good data. You should power off disks that are not part of the root volume group if you are restoring a bootable backup tape created with the -t option set
to non-zero values.
Verify that the system time is correct after recovery, and update if necessary.

Re: BBTCREATE for Virtual Vault
Watch out. There's a known problem with panic when using bbtcreate tapes to recover, noted in VVOS Release Notes (B5413-90064). According to the hardware matrix, this does not apply to our PA8500 processor, but we're experiencing the symptom when trying to do a boot tape recovery. Our hunch is that after we complete our cold-install recovery and apply the patch referenced in the document, we'll find that the issue did in fact apply to our hardware.
To make things worse, you can't find anything about this on ITRC when searching on "bbtcreate", and the RC does not seem aware of it (we've had a RC ticket open for a couple of days, and one of my engineers just happened across the note in a hardcopy of the document).
