Get to the ok prompt and type:
boot cdrom

One way is to use serial console and send a break/Stop-A. You can also use ALOM (type #. to get there).

How do you tell a v440 to boot from CDROM? I put the disk in , but it just tries to boot from the HD over and over, without prompting me to boot from the CDROM.

#mount /dev/dsk/c0t6d0s0 /a ... bcoz cdrom devices will mount under /a when it enters in to single user mode.....

yes because you are on /a mount (root). you must type pwd to see where you are ? and thereafter to go on root/ to cdrom and type umount /a so that ok

Hi,

My SunFire V440 won't boot from Solaris 9 Installation CDROM, Solaris 9 CD 1 of 2, or from Solaris 9 DVD. (boot cdrom)

In all cases, it gets through the POST, initialises all memory, tells me the boot file and device, gives me the spinner and then tells me it cannot open kernel/sparcv9/unix

That's the 64-bit file, so I've tried giving it the normal location of the 32-bit file:
kernel/unix

It cannot open that file either.

All I want to do is wipe its disks before sending it back to the leasing company.

It has a working Solaris OS onboard. Any ideas how I can boot from the CD/DVD or how I can wipe the disks while booted from one of them?

Thanks,
cla.

All - :?

I consoled in because its off the network. I used the aforementioned process to boot by cdrom, but have had a 'NULL' result. after removing the password entry from /etc/shadow and saving (wq!), I issued an init 6 to reboot. from this point it asked me for the user login (no problem, its root so i typed root) but when just hitting enter when propted for password I get Login incorrect. :?:

please help

I'm glad it helped. This technique has saved me many a reinstall, too.

Bob, If you still can't see your boot disk, it may be called something different than c0t0d0s0. You can run iostat -En to find the names of disks, although this won't tell you which slice you need.
