Chapter 8 Administering MFS Disks 8-9
Following invocation without the -f option, mkmfs prompts you for the information
required to build an MFS. For example:
You specify the parity drive(s) after you have entered all data drives. The number of
parity drive entries must correspond to the number you entered at the “Number of
parity drives:” prompt. In the example above, there is one parity drive specified, so
mkmfs assumes the last entry, /dev/rdsk/c1t6d0s2, is that single parity drive.
When you use the -f option, you must supply the pathname of a file that contains
the information required to build an MFS. Shown below is an example disk
configuration file that contains the information entered manually in the previous
example.
