hpux options from ISL prompt.

[RAC_1]

Recently I read a thread that spoke about hpux -M option from ISL. (In that case it was used to limit the memeory to be used.)

What such all options are available??
and is it documented somewhere?? I read hpux, pdc and isl, but of no use.

Thank you in advance.

for grins & giggles,
I got no error using the -M flag


ISL> hpux -M

Boot
: disk(0/0/1/1.15.0.0.0.0.0;0)/stand/vmunix

if you do a in mult-user mode:
$ man hpux
there is no such -M flag for memory size.
of course I do see the: hpux -lm
for lvm maint mode.

Hi,

See this man page of hpux.

RAC ... Some confusiom even -H option works.
I doubt if it has any significance. It may be just ignoring that parameter and continues booting.. :)

Yes, as Bharat stated, hpux must be ignoring any option which it cannot understand !!

There is also an undocumented -D flag, not to be confused with -aD. It takes an argument of a hex number which is the debugging level.

e.g.

ISL> hpux -D0x02

This comes in useful sometimes if you think a boot is hanging, try it again with the -D flag and you can see if it is actually doing anything.

The output isn't particularly meaningful, a whole load of low level system calls mainly involved in moving bytes around, but if the boot process is still printing debug messages at least you know it hasn't hung.

Anil,


h'mm, there is a maxmem flag, but this may not be supported..

-maxmem=MEM Set the maximum amount of memory to MEM.

Robert-Jan Goossens's link helped. The undocumented option is there.
