Do you have a DVD writer? If you can assign that to the LPAR with the mksysb image, you would then:-
I'm assuming that the DVD writer is detected as cd0
Use DVD-RAM media, not DVD-R, DVD-ROM or DVD-RW.
To get you round your request short term, you can make a virtual optical device on the VIO server and assign that. The same commands on the LPAR with the mksysb image file.
Two important points:-
If you don't have a DVD writer, what is your recovery plan? Consider either LPAR will not boot or total server loss. If you are backing up the VIO server, then this is just the VIO server operating system and not the virtual disks assigned to the LPARs. .
Create your new LPAR without any network cards defined and assign the optical media (physical or virtual) to it before you activate it. If you restore your image with the network definitions in place, then the server will boot and cause conflicts with the system it is cloned from.
When the server has been running, then shut it down, assign the network cards and activate it again. You will still only have the console, but then you can put on the addresses you want to use.
I hope that these suggestions help. Let us know what you plan to do and how you get on, or if neither of these is viable.

I have several systems which require software maintenance several times a year. After the software maintenance, it is required that we make two system tapes for DR purposes. The creation of these system tapes takes anywhere from 1-1.5 hours because of the performance of the tape drives. What I... (7 Replies)
Hello,
I have an mksysb image in my disk, created like:

Hi Folks,
How to restore mksysb image on LPAR which is already having cloned AIX OS installed on hdisk0 (nothing configured, only full partition image is sitting on hdisk0)
Let me know.
Thank a lot. (1 Reply)
This may be a dumb question and the more I think about it the worst it seems!!
I have inherited some standalone systems where they are using the mksysb command to create a disk file image; this image is then backed up to Networker.
My dumb question is how would we go about restoring this... (4 Replies)

mmcformat
MMCFORMAT(8) BSD System Manager's Manual MMCFORMAT(8)NAME
mmcformat -- format optical media
SYNOPSIS
mmcformat [-BDFGHhIMOpRrSsw] [-b blockingnr] [-c cert-num] special
DESCRIPTION
The mmcformat utility formats optical media conforming to the MMC standard. This includes CD, DVD, and Blu-Ray (BD) media.
The options are as follows:
-B Blank media when possible before formatting it.
-b blockingnr Explicitly select packet size in sectors (for CD-RW only). It is not recommended to change this from its default of 32.
-c cert-num Certify media for DVD-RAM / DV-RE. The argument cert-num specifies:
0 no certification
1 full certification
2 quick certification
-D Debug mode. Print all SCSI/ATAPI command errors.
-F Format media.
-G Grow last CD-RW/DVD-RW session.
-H Show help and print formatting choices for the inserted media.
-h Show help and print formatting choices for the inserted media.
-I Show help and print formatting choices for the inserted media.
-M Select MRW (Mount Rainier) error correcting background format.
-O Old style CD-RW formatting; recommended for CD-RW.
-p Explicitly set packet format.
-R Restart previously stopped MCD-MRW or DVD+RW background format.
-r Recompile defect list for DVD-RAM.
-S Grow spare space DVD-RAM / BD-RE.
-s Format DVD+MRW / BD-RE with extra spare space.
-w Wait until completion of background format.
NOTES
Due to the enormous varieties in optical media, mmcformat is made as generic as possible. This can result in confusion.
EXAMPLES
mmcformat -B -O /dev/rcd0d
Blanks and then formats a CD-RW disc using the ``old style'' format command. It is recommended to use this ``old style'' command unless your
drive reports that it's not supported; in that case, resort to the default -F. Note that a CD-RW disc can be reformatted without being
blanked. Blanking switches between sequential and fixed packet writing by erasing the disc. This can also help to revive old discs.
mmcformat -F -M /dev/rcd0d
Format a CD-RW or a DVD+RW to use MRW (Mount Rainier). This format tries to hide media flaws as much as possible by relocation.

The mmcformat command first appeared in NetBSD 5.0.

BUGS
mmcformat could be merged with scsictl(8) but that tool is very hard disk oriented.
