IMPORTANT:

The above output includes block device special files ending with _p1, _p2, or _p3. These endings indicate an idisk partition on the disk. Do NOT use a partition as a clone target!

The last disk in the above list is a DVD drive, indicated by the DW in the description field. Do NOT use a DVD as a clone target!

Some device files are identified as /dev/rdisk following the block device special file designation. This identifies them as raw files. Do NOT use a raw file as a clone target!

Additionally, on HP-UX 11i v3 Integrity systems, you may find it useful to use the following ioscan command to identify persistent and legacy DSFs:

Example 2-4 The ioscan -m dsf command output on an HP-UX 11i v3 Integrity system

# /usr/sbin/ioscan -m dsf
