Re: vxfs fsck: sanity check failed: cannot stat /dev/rroot

You could try to recreate the nodes...

First take a look in /dev...

ls -l /dev/*root
brw-r----- 1 bin sys 255 0xffffff Aug 24 11:57 /dev/root
crw-r----- 1 bin sys 255 0xffffff Aug 24 11:57 /dev/rroot


If you do not see either of these, proceed as follows:

mknod /dev/rroot c 255 0xffffff
mknod /dev/root b 255 0xffffff
chmod 640 /dev/*root
chown bin:sys /dev/*root

Reboot and check ...
