Solaris Common Messages and Troubleshooting Guide

Block device required


A raw (character special) device was specified where a block device was required, such as during a call to the mount(1M) command.


To see which block devices are available, use ls -l to look in /devices. Then specify a block device instead of a character device. Block device modes start with a b, whereas raw character device modes start with a c.
