Mixed vPars Environments

[System Unix]

Hi,

I have installed mixed vPars v5.05 on HPUX 11.31 together with vPars 4.03 on HPUX 11.23. everything works fine.
after issuing the command mkboot -a "hpux /stand/vpmon -a" /dev/rdsk/cXtYdZ is there way the see how the vpar will be booted?
like what disk? is it vmunix/vpmon ?

thanks

After a power on of a server the system will be boot vpmon, each vPar will then boot the vmunix kernel. You can see the boot process while toggling the console.

Hi Torsten,
thanks for your reply.

my question was to find the boot params while vpars are up, like if you create a vg with disks a,b,c the command vgdisplay -v will show all the disks that the vg was created from.

can I do the same to see the boot details of each vpar ? ( a command that will show me hpux /stand/vpmon and the disk cXtYdZ )

rgards,

You need to make a difference here!


The startup file that points to /stand/vpmon is somewhere on the LIF/EFI (depends on machine) and is only used after a cold start or nPar start, the startup for each vPAR OS is in vpdb file (check with vparstatus).

Hi Torsten,
I am looking for something similar to echo 'boot_strings/S'|adb /stand/vmunix /dev/kmem that is on PA-RISC but will be similar on Ia64 in vPars environment. or any EFI other commad or lifls etc...

thans,

Each (vpar or not) system is loading /stand/vmunix, so there is no difference!



The difference is only during a cold start.


After the firmware is loaded, the system attempts to boot from the configured boot disk and reads the configured boot string.


AT this point ONLY the /stand/vpmon is used to load the vpmon.


From that point on each vPar instance is started just like a normal stand-alone system by /stand/vmunix (but the vpdb file is emulating the LIF/EFI area and delivers the boot string).



So if you ask a vPar instance, the answer is always it is booted with /stand/vmunix.
