2. Create a directory for the volume group. This is located in the /dev directory.
Enter the following command to verify which volume groups exist.
# Is /dev
You see a directory similar to the one shown below.
From the above list, the only volume group that exists is vg00. For the purpose of
this example, vg01 has been created.
3. Enter the following command to make the directory vg01:
# mkdir /dev/vg01
Note: The standard HP-UX kernel supports vg00 to vg09. Creation of volume groups
greater than vg09 requires kernel tuning. Refer to the appropriate HP-UX
documentation for this information.
4. Create a control file named group in the /dev/vg0n directory created in
step 2. This is done with the mknod command:
# mknod /dev/vg0n/group c 64 minor_number
The minor_number for the group file is hexadecimal. This minor_number
always ends in ‘0000’ and is in the form
0x0n0000, where again n is the
identity of the volume group being created.
