I hav 2 disks internally in server which are mirrored..

disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 36.4GMAU3036NC
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 36.4GMAU3036NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0

The server cannot read from the disc.

Could be a bad media or a firmware problem.

But mostly the error pointing that the primary boot path has failed. after booting, is theere shown the two internal disks?

[Pramod M]

Hi Thanks for responses...
Yes both the internal disks are showing as claimed after booting.. And there is no disk error in the syslog also..

[V. Nyga]

Hi again,

ok - you have two disks, but which path is announced as primary boot path?
Check your boot menu.

[Pramod M]

hi...
the setboot out put shown below..

# setboot
Primary bootpath : 0/1/1/0.0.0
Alternate bootpath : 0/1/1/0.1.0

Autoboot is ON (enabled)
Autosearch is ON (enabled)


Thanks

Hi again,

you said 'And there is no disk error in the syslog also..' - well, when the system boots from the second disk, then you'll get no error messages from a defect boot sector of the first disk.
You should test the first disk with a 'dd' command:
'dd if=/dev/rdsk/c2t0d0 of=/dev/null bs=4096k'
Let it run and check the result.

Somehow the LIF area went bad - this is not necessarily a bad drive!

Once the LIF area is repaired, its probably ok.

[Pramod M]

Hi thanks in advance..
Hope i can repair the LIF area using the 11.11 install and recovery dvd. Hope there will be no risk in this. can u pls giv me the steps to follow?
Thanks again...

[V. Nyga]

Hi again,

this is one sense of mirroring disks - just break the mirror, use the bootable disk for booting, then recreate the mirror and use the other disk as the new mirror disk.
Check this thread for the first steps:

Hi again,

see also Matti's answer:
1.) Sanity check: verify that the bootloader exists on both halves of the mirrored system disk (PA-RISC: lifls /dev/rdsk/, Itanium: efi_ls -d /dev/rdsk/s1).

Hi..
I used recovery Cd to recover the LIF. It was success but now the server boots to single user mode after giving the following error


/sbin/ioinitrc:
fsck: /dev/vg00/lvol1: possible swap device (cannot determine)
fsck SUSPENDED BY USER.
/dev/vg00/lvol1: No such device or address
Unable to mount /stand - please check entries in /etc/fstab
Skipping KRS database initialization - /stand can't be mounted


INIT: Overriding default level with level 's'

INIT: SINGLE USER MODE

INIT: Running /sbin/sh
#


this was occured after the recovery of LIF..
Pls help to solve .. Thanks in advance..

[Torsten.]

>> dev/vg00/lvol1: No such device or address

You should try to set the config again with

lvlnboot -r/-b/-s/-d ...

lvlnboot -r /dev/vg00/lvol3
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2

[Pramod M]

Hi Torsten,
I tried by setting again the lvlnboot -r/-b/-s/-d and still the problem exists..

Any other options?

Thanks..

[Pramod M]

Hi Thanks to all again...
Closing this thread..
It was due to the change in hpux autofile after recovering the LIF.

ISL> hpux show autofile

Show autofile
: disk(0/1/1/0.0.0.0.0.0.0;0x800000)
AUTO file contains (hpux -lm /stand/vmunix)



ISL> hpux set autofile "hpux /stand/vmunix"

Set autofile
: disk(0/1/1/0.0.0.0.0.0.0;0x800000)
AUTO file now contains (hpux /stand/vmunix)



Thanks for responses...

this is a fundamental problem with our boot disk . it may have been caused by a disk head problem.
you can use the core OS install and recovery media to fix it.
