Error Messages (Continued)

Message:

Explanation:

Response:

panic: vfs_mountroot: cannot mount root

rebooting...

resetting....

The system is misconfigured.

There are two possible causes:

1.You attempted to boot from a nonbootable device. Check the device name and try again. The alternate boot device may be set up incorrectly.

2.You failed to reboot after mirroring root

(olds -mirrored -setroot), leaving the system unstable. In that case, do the following:

a.Boot from the CD.

b.Mount /dev/dsk/c0t0d0s0 /a (or whatever partition is your root partition).

c.Remove Solstice DiskSuite entries from /a/etc/system (i.e. everything between tags "mddb ...")

d.Remove /a/etc/opt/SUNWmd/md* files, i.e.:

rm /a/etc/opt/SUNWmd/md*

e.Replace /dev/md/rdsk/d21 entries with /dev/rdsk/c0t3d0s0 (or whatever your boot device name is).

f.Boot: /usr/sbin/shutdown -y -g0 -i6

g.If the system still refuses to reboot, reload Solaris.


Message:	filename restored from filebackup
Explanation:	The action failed, and the md.tab file was restored from
	the previous version. Consequently, the configuration files
	reflect the previous system setup.
Response:	Determine the cause of the problem and try again.


Message:	resync in progress
Response:	The command entered cannot be executed because the
	mirrors are currently being resynched. Try again later.
	You can tell whether a resync is in progress by entering a
	metastat command.
