Think I may have typo in 'vfstab' and get

/dev/rdsk/c1t0d0s6: is clean.
/sbin/rcS: /etc/dfs/sharetab: cannot create
failed to open /etc/coreadm.confsyseventd: Unable to open daemon lock file
'/etc
/sysevent/syseventd_lock': 'Read-only file system'
INIT: Cannot create /var/adm/utmpx

INIT: failed write of utmpx entry:" "

INIT: failed write of utmpx entry:" " , on boot

System will come up single user , with readonly file system

What are my options to fix this?

Thank

GC

Your best option is to boot off the CD or the network into single user
mode and then mount the disk and replace whatever the bad entry is. I
would recommend taking care if the disk was mirrored, but it appears
that it is not, so do not worry.

Please note, this is hand typed and there may be some typos in it.

ok> boot cdrom -s
password:
#mount /dev/dsk/c1t0d0s2 /mnt
#edit /etc/vfstab
do stuff here
#umount /mnt
#sync
#init 6

I hope this helps.

Regards,

Nathan Dietsch

You may try:

uadmin 4 0

and then edit your vfstab, if it didn't panic of course :-)

"uadmin 4 0" sets the root device read/write without consulting vfstab.

that would be /mnt/etc/vfstab

No password is requested when booting single user from cdrom.

There should not even be a filesystem on that partition. The root
partition is normally on s0.

vi is available on the miniroot. Also it is preferable to fsck the root
partition before attempting to mount it.

Am I imagining it, or would

mount -o remount,rw /dev/dsk/c0t0d0s0 /

(replacing c0t0d0s0 with wherever the root filesystem is, of course).

Also do the trick?

Probably, but I thought that you would be the first person to resort to
uadmin... if only for brevity of command line ;-)
