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.

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... (1 Reply)

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files.  If a des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b
