Boot Problem
Changed kernel parameter for oracle10g R2 and rebooted the system.
Got numerous errors : like Sysconfig tab attributes not set in subsystem ipc...and more..
I am able to login to single user mode now.
Replaced the original sysconfigtab file.
Still I got the same problem.
I tried bcheckrc and
got the following error:
Checking device naming:
Passed.
Checking local filesystems
Mounting / (root)
Cannot find boot filesystem mount point
mountroot: Please correct the mount problem and reboot
I tried running bcheckrc and got the same error message. The following is my /etc/fstab file:
root_domain#root / advfs rw 0 0
/proc /proc procfs rw 0 0
usr_domain#usr /usr advfs rw 0 0
The root domain is currently mounted and I could successfully mount the usr domain as well.
Any ideas on how I can fix this?
Please let me know if i need to try anything else,its very urgent for me to get this system up.Thank you.

Re: Boot Problem
In single user mode, sysconfig -s - shows nothing. sysconfigtab and sysconfigdb -l are perfect, but while booting both both vmunix and genvmunix are not able to get these attribute values.

Re: Boot Problem
Go back to the beginning...
Exactly what did you change when you "changed kernel parameter" ?
The errors "...attributes not set in subsystem..." should not stop the system booting. They're just an indication of typos in /etc/sysconfigtab.
What's the hardware configuration ? Clustered ?
Cheers,
Rob

Re: Boot Problem
The system is not clustered.I have replaced it with the original sysconfigtab.All I have is usuable single user mode.
I believe syconfig with wrong parameters changed the setting of running kernel.I dont have a log to tell you the exact parameters,sorry.
When the system boots it checks ./vmunix or /gemvmunix as per the selection and both kernel are not allowing me to login.
/vmunix or /gemvmunix are not updating the current information from sysconfigtab.
Do you think is it possible for me to replace these two files from tape or to build a new kernel ?

Re: Boot Problem
I'm not entirely sure what's gone wrong, but you might want to try booting from the generic kernel, and rebuilding a new one.
P00>>> b -fl s -fi genvmunix
Once at single user,
# mountroot
# mount /usr
# mount /var
# doconfig
Once the kernel has been built, you will need to copy it to /
Hope this helps,
Regards,
Rob

Re: Boot Problem
Mounting / ( root )
Cannot find boot filesystem mount point.
mountroot:please correct the mount problem and reboot.I am not sure how to fix this issue.
did
#dn_setup ├в sanity_check - passed
#dn_setup ├в init
#dsfmgr ├в K
#dsfmgr ├в v is successful
#disklabel ├в r dsk0 and dsk1 are fine.
#/etc/fstab and inittab looks fine.

Re: Boot Problem
I tried
consvar -g booted_dev
booted_dev =
consvar -s boot_dev dsk0
consvar -a
No idea these changes are not effective after a boot.

Re: Boot Problem
Not sure if this could be a cause ?
Have you checked /etc/fdmns ? Are the links pointing correctly to the proper device names ?
