To display the different bootstrings for a disk:

  # lifls <rawdevice>

For example:

  # lifls /dev/rdsk/c0t6d0

A bootable disk reports something like:

  ISL          AUTO         HPUX         PAD          LABEL

While a non bootable disk reports:

  lifls: Can't list /dev/rdsk/c0t6d0; not a LIF volume

To show the content of the bootentries:

  # lifcp <blockdevice>:<STRING> -

For example:

  # lifcp /dev/dsk/c0t6d0:AUTO -
  hpux

For further information on LIF, refer to lif(4).
