I cannot seem to boot off tape in SMS.

I created a MKSYSB backup to tape using: mksysb -iev /dev/rmt0
Verified it using: lsmksysb -l -f /dev/rmt0

Booted to SMS menu, selected Tape as the boot device and set Media Type to SCSI, it throws an error: The selected devices were not detected in the system.

I then try using the "List All Devices" for Media Type, it does a scan and comes back with the tape drive....

Code:

PowerPC Firmware
 Version FW910.20 (VL910_122)
 SMS (c) Copyright IBM Corp. 2000,2017 All rights reserved.
-------------------------------------------------------------------------------
 Select Device
 Device  Current  Device
 Number  Position  Name
 1.        -      FC Tape drive
 -------------------------------------------------------------------------------
 Navigation keys:
 M = return to Main Menu
 ESC key = return to previous screen         X = eXit System Management Services
 -------------------------------------------------------------------------------
 Type menu item number and press Enter or select Navigation key: 1

This seems to work in that the next screen I get a select task option where I choose the Service Media Boot, this fails with: No Operating System Found

I am stuck, seems that I cannot boot off the newly created MKSYSB tape.

Any ideas what I can try? I have since escaped from here and booted back to AIX normally.

[Tip] Backup and restore on AIX

Pretty penny's. Just remember that mksysb and savevg are just front-ends for backup. In other words, backups on AIX are organized by volume groups. mksysb is specialized for rootvg and savevg is used for other volume groups. Ignoring that rootvg also creates files needed to boot a system...

bdb.db0

BDB.DB0(5)							AFS File Reference							BDB.DB0(5)

NAME

       bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log

DESCRIPTION

       The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross-
       indexed records of the tapes created and volumes dumped using the Backup System commands.

       The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an
       operation is interrupted, the Backup Server replays the log to complete the operation.

       Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup
       Server.	When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its
       copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database
       technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number.

       Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape
       on a regular basis, using the UNIX tar command or another local disk backup utility.
