ISL> hpux -is

That is all you need. If full syntax is required (pre 10.20), then:

ISL> hpux -is disk(;0)/stand/vmunix

No disk hardware path is required at ISL, because you wouldn't be at
ISL unless you had previously supplied a path argument with your boot
command from MAIN MENU.

If you are at ISL and having problems booting, you can do a listing of
the root filesystem:

ISL> hpux ll disk(;0)/stand/ .

Bootable kernels will have an * next to them.

To clarify the above commands, "disk" is literal (type disk, not the
hardware address). ;0 is an old convention from when we did hard disk
partitioning (0 being the first partition).

Good luck,
