The format of the bootable DVD and CD 1 of Solaris 10 U6 sparc has changed from previous Solaris 10 update's sparc media, it now seems to be more like the x86 format, can anyone provide the new/specific mkisofs command to use to recreate (modified version) a sparc bootable ISO image file of these from their "unloaded" directory paths, I'm guessing the mkisofs command is going to be similiar what's used for recreating Solaris 10 x86 DVD and CD1.
Thanks for info, when I try this mkisofs command to recreate the Sol 10 U6 CD 1 ISO image I end up 16 KB short of the original downloaded ISO size of Sol 10 U6 CD 1, the generated ISO image when burn to CD doesn't boot, I tried using both mkisofs version that comes with Sol 10 U6 & version *2.01.01a53*, here's the test I did:
mount Sol 10 U6 CD 1 as /mnt (CD 1 burned from downloaded ISO from Sun that is *512904 KB* in size)
Sorry, big false alarm, the mkisofs did create a bootable ISO image, despite the 16KB difference in sizes, my suspected boot problem turned out to be an issue with the CD not being inserted correctly (far enough in) on a newer tray-less CD drive to be able to mount, I was remote to the physical server and had a co-worker check the drive. Thanks again Alan for the info.
Your statement is off-topic, but for the record It is a bootable DVD image. Many people use it all the time. If it does not boot for you, it could be due to hardware-related issues or how the disc was burned.
Please check previous postings in the various forums. This type of question has been asked many times. Obviously the image can be downloaded, burned and booted, since many people have done so. Other forum replies include questions on DVD media quality, hardware errors if you try to mount the disc on a running system, etc. Maybe you want to try the latest release S10 U8 (10/09) and see if you have any issues.
GRUB AND THE SOLARIS OPERATING SYSTEM ON X86 PLATFORMS - A GUIDE TO CREATING A CUSTOMIZED BOOT DVD

I understand the differences in the boot process for Update 8 and I am running into trouble de-composing the DVD (hsfs.bootblock, Grub menu, custom configuration). John Cecere's document was extremely helpfull for x86. I am now working on a Sparc version. I am specifying a "config.tar" in the Grub menu on x86 and I'm hoping the same process will work on sparc.
Sorry, I don't know of any equivalent document for SPARC. You could try going to bigadmin.com and asking or poking around there. But I believe the processes are much closer now than they were, so you might be able to get it functioning.
I believe the mkisofs command you provided in this thread is good. I'm trying to adapt the x86 "find ... cpio" to build the staging area. Do you know if that will work? I have found references to 8 slices on the SPARC DVD. What effect does that have?
