Emergency UNIX and Linux Support

Hi all,
I have unbootable Solaris 10 x86 installed on ZFS root file system. on an IDE HDD

The bios keep showing the msg

DISK BOOT FAILURE , PLEASE INSERT SYSTEM BOOT DISK
please note : the HDD is connected properly and recognized by the system
is there any guide to recover the system , or detail procedure to boot system again
Thanks,,,

boot from dvd... and check the filesystem...

1- please note root file system is installed on ZFS file system
and as far as i know you cant' use fsck on zfs file systems

2- boot from dvd in single user or in failsafe mode
if applicable please i need detailed steps or detailed guide

please note the following :
1- The HDD is connected properly and recognized by the system
2- The bios keep showing the msg DISK BOOT FAILURE , PLEASE INSERT SYSTEM BOOT DISK
3- GRUB don't even show any message or even the splash screen

you CAN check a zpool. you can import the pool after booting from dvd and do a resilver if possible and necessary. but the error looks like your bootblk is gone... if this is the case you can use:

Code:

sparc# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0
x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t1d0s0

to reinstall the bootblk.

i booted from the dvd in single user shell, but it didn't find the previous os installtion
i do see the hdd when i ran

Code:

#echo | format

any further idea

you won't find the installation because it is on an zpool... did you try to import the rpool and have a look if the data is still there? if you see the hd, have you tried to restore the bootblk?

@DukeNuke2

what is the exact command to recover the pool in single user shell , do i need to mount anything
I ran

Code:

# zpool list
no pools available

with no luck i cannot see any pools
help please i'm lost
