ISL command

Hi Everybody,

I have a doubt, why do we use "(;0)" while issuing following command at ISL?
Is this "(;0)" necessary?

ISL> hpux –is (;0)/stand/vmunix

Thanks,
RK

Re: ISL command

It's not necessary - only for backward compatibility.

This specifies the disk section/slice to boot from, see man isl and man hpux.

"section" 0 is the default.

Hope this helps!
Regards
Torsten.

Booting From Another Section
In this example (shown for backward compatibility), a kernel is booted from another section of the root disk. For example, suppose kernel development takes place under /mnt/azure/root.port which happens to reside in its own section, section 3 of the root disk. By specifying a minor number of 3 in the above example, the object file sys.azure/S800/vmunix is loaded from /mnt/azure/root.port.

ISL> hpux (;3)sys.azure/S800/vmunix

Boot
: disc(8.0.0;0x3)sys.azure/S800/vmunix
966616+397312+409688 start 0x6c50
