Re: password recovery in RAID1

MY SOLUTION is:

boot cdrom -s
mount my device /a
delete password in /a/etc/shadow
umount /a
mount my secondary device /a
delete password in /a/etc/shadow
halt
(in prom mode) boot -s
passwd
(add a password to root)
passwd -x -1 root
(turn off passwd aging)

Thanks everyone who involved this issue..

I usually unmirror the / filesystem to do this.
You need to:

- boot net -s (or boot cdrom -s )
- fsck the relevant device (for example /dev/rdsk/c0t0d0s0 if that is a
member of your / filesystem's mirror)
- mount the device, chroot into it, edit /etc/vfstab and /etc/system so
that the / filesystem and the bootdevice is no more an md device.
- change password
- exit from chroot
- sync
- umount mounted device
- halt
- boot disk (if this is hte devalias pointing the the device you just
mounted)
system shall be running now with the new password and without a /
mirror, however other mirror shall be intact.
- rebuild mirror.

the other opportunity is (never did that yet though, so if it is a prod
system, better not try), after boot net -s :
fsck, mount device, modunload md kernel module, copy von der device the
kernel/driver/md.conf file to /kernel/driver/md.conf, modload md, and
try to mount metadevice, change password.

Hi,
does anyone know how to do root password recovery for mirrored root
exactly, I tried to delete root passwd in /etc/shadow file but system
again asked me a password.

Do we need to unmirror ? but metastat did not worked..
Thanks in advance
