Answer / venu gopal

you have to specify the boot device in the ok prompt i.e,
your default boot device not having OS or /etc/system or
/etc/vfstab file corrupted.
boot in interactive mode (ok boot -a)specify boot device as
cdrom,check this (ok printenv auto-boot?)
auto-boot?=false
if it is false then u have to boot manualy

Answer / mathai

if system in ok prompt, then the problem with boot-device
or alias name. if it is problem with vfstab, system boot in
mantenance mode

Answer / sainu daniel

There are few possibilities..

Primary disk might have failed and secondary boot path
might not be correct.or alias for the secondary path is not
correct.

check following and correct if needed.
ok>printenv boot-device
ok>printenv auto-boot?
ok>devalias <boot device>

once you verified and corrected,
ok>setenv auto-boot? true
ok>reset-all

Answer / sumit

After all may be the boot block is corrupted or not
installed into the second disk if the disk is mirrored. if
that then need to install bootblock into the second disk
will solve the issue.
boot with cdrom
run installboot /a/usr/platform/`uname -
i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0

Answer / wipro

if the disks are in SVM, and the system do not boot up...
possibly due to the it is not able to find the boot disk.
if that is the situation we wil get a message like "CANT
OPEN BOOT DEVICE" and the system will return to OK> prompt.

in this situation the saved disk info in the OBP is wrong.

Check the disk aliases and try to boot the server. if again
failed.

boot the server in failsafe.
check the disks : echo | format
mount the disks and check.
remove the disks from svm , by editing /etc/system
and /etc/vfstab file .
drop the server to OK> prompt
now boot the server using the disk alias like disk0 ,
disk1 .... for eg : ok> boot disk0 (or) disk2
once booted.. check the disk status and delete the meta and
recreate them back properly, and attach the disks.
