Hi praneep,

The ISL utility checks the AUTO file to find which kernel to load on a PARISC server. The equivalent prompt on integrity is the HPUX prompt. Most of the tasks done can be executed on the HPUX prompt which is done on ISL on PARISC.

A quick way to answer this question would be to replace "hpux" with "boot vmunix" for many of the commands

For example for booting with low qourum on PARISC it would be
ISL> hpux -lq

On Integrity,

HPUX> boot vmunix -lq.

The ISL (initial system loader) on a RISC system is loaded from the disk. Normally you have the choice of booting hpux system loader or something different present in the disks LIF, e.g. ODE.

The Itanium systems combine the RISC's BCH and ISL in EFI. There are some commands you can compare, you even have a help, e.g.

Shell> help bch
------------- Main Menu -----------------
Command Type at shell prompt:
------- ---------------------
COnfiguration help bch co
INformation help bch in
PAth help bch pa
ScRoll help bch sr
SEArch help bch sea
SERvice help bch ser
BOot help bch bo
HElp help bch he
RESET help bch reset
MAin help bch ma

this will give you a help how to "translate" the RISC's BCH commands into "Itanium language".
