About the differences between using only "hpux" and "hpux -lq", when say, my alternate root disk goes bad , and i am booting with only my primary disk. Which option should i go for?
Thanks in advance.

SolutionUse "hpux -lq" in a mirrored environment.

Re: About "hpux -lq"
Suppose the primary disk is OK and the alternate disk has gone faulty. In that situation, as have seen in 9000 systems - the processor does boot from the first available device automatically.
In that situation, and in another, where we interrupt and go with the "hpux -lq" option from ISL, is there any major difference in the environment? Are there any extra processes that get forked when the system keeps looking for the second disk (when not using the -lq option). I remember hearing that kind of a situation someone faced with a SD32 vpar, where lots of like processes (can grep with "evmshow") come alive and eat away the resources. The system becomes very slow and irresponsive. One can start killing the processes, but they keep on coming.

Re: About "hpux -lq"
Just want to ask - is there any significant performance change between booting hpux using -lq and not using -lq, when one disk is out (in the 2-copy scenario) ?
Sorry for repeating, just want to be clear on that.

Re: About "hpux -lq"
Yes, the bootloader will successfully load the kernel - but if vg00 is mirrored with MirrorDisk and "-lq" is not specified, as soon as the kernel tries to activate the vg00 volume group for mounting the root filesystem, the kernel will panic if the alternate half of the mirrored system disk is not available.
This is because the standard quorum requirement prevents it from activating vg00 and thus from mounting the root filesystem. Without the root filesystem, the boot cannot complete.
The effect of "hpux -lq" vs. "hpux" for vg00 is similar to "vgchange -a y -q n" vs. "vgchange -a y" when mounting a data volume group that contains failed mirrors: it allows the VG to be activated even if the mirror is not whole. It has no other effects.
If you're not using MirrorDisk, then the "-lq" option is not necessary for you.
For example, if your vg00 is on a single disk and your alternate boot disk is a DRD clone of the primary boot disk, there is no need to use "-lq".

Re: About "hpux -lq"
The quorum is introduced as HP wants to insure if you have atleast a mirror disk.
This quorum checking is removed using hpux -lq.
