PANIC : All VFS_MOUNTROOTS Failed: NEED DRIVERS ?????

[Soumen]

Hi,

Can some help me with this . I have a HP Visualize Work station which crashed due to power failure now when I try to boot it it says --------
PANIC : All VFS_MOUNTROOTS Failed: NEED DRIVERS ?????

I have tried single user mode through
ISL> hpux -iS
Also I have tried booting from prevoius kernel
ISL> boot ll /stand/vmunix.prev
ISL> boot /stand/vmunix.prev

But nothing seems to work.

I think the driver is causing the problem. I tried to boot the system using CDROm
ISL> boot P0 -> where P0 is my IDE CDROM device.

I think if I can boot using the CDROM I will be able to install the drivers using the insf -e command but I am not able to use the Single user mode/Maintenance mode. Etc
CAn you please help me boot the system using the cdrom. The CDs I have is UP Core OS / Restore, Install CD fro HP UX 11.

A step by step guide will be appreciated.

Thanks,

Hi,

Have a last try with :

ISL> hpux -lm

and then recreate your boot information using lvlnboot -b, -r, ...

Jean-Louis.

One more small thing.

Do a: "sea " at the prompt as well to search for bootable disks including your CD. To make sure that you can see any bootable devices.

IF not, then you will prob have to do as above and boot into maintenance mode to repair the damage...

Make sure you know the paths for your boot disk

Another potential problem could be hardware. Do the "sea" at the BCH menu. If you do not see all of your devices, it is possible that an HBA is toast. If you see only some of the devices, look for something the missing devices have in common, are they all on the same hardware path, that sort of thing. It is also possible that it is a driver issue, this would be indicated if you could not see any devices of a certain type regardless of the hardware path.

Thanks for the Reply,

I have alredy tried issuing the commands and entrring the maintenance mode, but it fails and gives the error and reboots.

When i do a search it listasthe bootable devices and then when I enter boot P0 ie my scsi device it panics gives the same error and reboots.

[Todd McDaniel_1]

it seems more and more like a H/w problem to me.

either memory or a bad card or the Disk. The only thing now I can say is to boot from a ignite or try to reinstall the OS.

if you cna try to determine if a H/w problem exists.

[Soumen]

I am not very comfortable with ignite. Can you tell where can i find a document where i will find step by steps. Also I just wanted to know where can I find the alternate superblock entries and how do I configure a depot.

Thanks,

I've faced with the same problem today .
I've booted the system from another disk and
run
#mkboot /dev/rdsk/c#t#d#
followed by
#mkboot -a "hpux (;0)/stand/vmunix" /dev/rdsk/c#t#d#

After that I've removed LVM logical volume links to root, primary swap, or dump volume with lvlnboot -r /dev/vgname
and recreated it again :
#lvlnboot -b /dev/vgname/lvol1
#lvlnboot -r /dev/vgname/lvol3
#lvlnboot -s /dev/vgname/lvol2
#lvlnboot -d /dev/vgname/lvol2
#lvlnboot -R
Thats all , I've booted the system from failed disk without any problem .
Good luck .
