Dual Boot

[Dave Hanson_1]

I've got to be able to support a number of different HP-UX releases. I've got an B1000 workstation to work with.
I know I can load different OS versions on seperate disks. Can I get an external scsi hard drive to boot also?

pvcreate -B /dev/rdsk/c#t#d# # is the actual numbers on the character device for the diesk

mkboot /dev/rdsk/c#t#d#

mkboot -a "phux -lq (;0)/stand/vmunix" /dev/rdsk/c#t#d#

You can interupt start and make it the alternate or primary boot path.

You can do an sea to find bootable devices.

Dave:

Yes. If the devices are connected to the external scsi bus, when you boot interrupt when it is selecting the boot device. Then enter SEA to search for bootable devices. You should see the disks as well as cdroms and tape drives.

hth,

In theory your server should be able to see it. Use the SEArch command in the PDC after you hook it up/set it up/reboot the server for testing.

the only thing I'd like to add is that there have been several posts in the last few weeks where people have tried using various 3rd-party drives without success - the server doesn't see them as a valid device. So it might not work depending on the make/model of the drive.

B1000 work station supports external Harddisks .. hence you can install the OS on the disk and boot from it ..

Yes you could load different OS version on external disk. At the time of installation carefully choose the right disk(external) and after the installation is done you can terminate the boot process at PDC and set the primary and alternate path to the disks.
And when ever you want off the different bersion just intrrupt the boot process and type boot pri or boot alt.

Hi there Dave,

Have a number of sites working like this, you can automate the boot up with the setboot command, that is you can, before rebooting the B-class, change the primary and alternate boot disks in the stable storage, saving you the hassle of having to interrupt the boot sequence.

Great if you are remote!
