How t o check disk is bootable or not ?

To display the different bootstrings for a disk:

# lifls

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 : -

For example:

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