That's what I thought and what I did - I was able to correct the vfstab entries by booting of CD and mounting slice 0. &nbsp;Thanks for confirming.

I want to be able to correct the vfstab file - do I mount /dev/dsk/c0t0d0s0 or should I mount the d30 mirror consisting of c0t0d0s0 and c0t1d0s0 - is that possible? &nbsp;What is the correct approach and why?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
