single user mode under vxfs mode enabled.


<1> I have SB100 with solaris 10 enabled.

OpenBoot 4.17.1, 512 MB memory installed, Serial #51439395.


Rebooting with command: boot
Boot device: first_disk File and args:

<2> Because my boss asked me to make a recovery plan when /etc/system corrupted, I test it on SB100 as follows.
- Backup /etc/system
- Edit /etc/system to make OS corrupt.
- Boot OS into single user mode via network, then recovery /etc/system
from backup

However, I experienced the step<1> error, My OS had veritas root vol enabled, My action plan can be executed on SVM enabled OS without any problem, I wonder whether anything should be pay atttention to if vxfs root volume has been enabled.

Use "boot -a" at ok prompt, and specify path to backed up /etc/system
