Hi vbe. Thanks for the reply. That's a good point. In order to do a restore I'd have to connect the tape drive directly to LPAR1 so I can boot from the image on tape. That sucks, but the good news is that this is a temporary backup solution until we reach our goal of using TSM. Basically, I figured this tape drive would be the fastest temporary solution.
Once we purchase Sysback (which is very soon) we will use Sysback to send image backups to our TSM tape library. We will also have a server with Sysback installed and configured with a list of network boot clients. We'll then be able to boot off the "Sysback server" and restore the LPARs from TSM.

Hi,
Is it possible to use mkdvd to create a bootable DVD using a mksysb on tape as the source image?
On the system concerned, we don't have enough free space to create the mksysb to file first, so would like to use the existing tape mksysb backup.
The DVD disk/s will then be used to boot a... (4 Replies)

tapeinfo
TAPEINFO(1) General Commands Manual TAPEINFO(1)
NAME
tapeinfo - report SCSI tape device info
SYNOPSIS
tapeinfo -f <scsi-generic-device>
DESCRIPTION
The tapeinfo command reads various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It
issues raw commands directly to the tape drive, using either the operating system's SCSI generic device ( e.g. /dev/sg0 on Linux,
/dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems.
One good time to use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API,
'tapeinfo' will report a more exact description of what went wrong.
Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended
to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information.
OPTIONS
The first argument, given following -f , is the SCSI generic device corresponding to your tape drive. Consult your operating system's doc-
umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).
Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls them. Under Linux,
"cat /proc/scsi/scsi" will tell you what SCSI devices you have.
BUGS AND LIMITATIONS
This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT).
AVAILABILITY
tapeinfo is currently being maintained by Eric Lee Green <eric@badtux.org> formerly of Enhanced Software Technologies Inc. The 'mtx' home
page is http://mtx.sourceforge.net and the actual code is currently available there and via CVS from http://sourceforge.net/projects/mtx/ .
