Vpars - local root disks - VA7400

[Janice Breaker]

Okay here's the deal. I have a vpar system (ver 1.01 - hpux 11i) running on a N4000. I have 4 partitions defined (env1,env2,env3 and env4). 2 of my paritions are using local disk (env1 and env2) for boot devices and the remaining partitions are using the VA as their boot device.

Each vpar has a fiber channel card, so I *can* have it so that I can boot each vpar from the VA. Here is my question(s) :

1) How can I convert env2 from booting from a local disk to a VA disk? I understand I have to make a Lun and assign the security via secure manager,etc. I really just want to know if I *already* have a boot disk which is local, how can I convert it to boot from a VA instead? And keep in mind, this env boot in a Vpar environment. Just to throw a wrench in it, I have some data on the boot disk that I still want to keep (someone made a vg01 on the root disk and install stuff there) grr!

2) My next question is, what are people opinion about a system which *only* boots from a SAN? Pros / Cons?

Thanks Guys.

What you can try to do is the following : copy all data to the new lun on the VA with the same volume-group layout (cpio -p). Create new lif header with mkboot. Be sure that the /etc/ioconfig file is empty. Try to boot the vpar in single-user mode and recreate /etc/ioconfig with ioinit command. Be sure that the fstab-file has the correct entries. As you can see, you will have a lot of work to reset/set the device-files correctly. Maybe, it is easier to use Ignite/UX to install the vPar and copy the data you need afterwards.
