11.23 to 11.31 with DRD?

Though the Dynamic Root Disk Administrator's Guide seems to indicate this is not possible, the responses in the following thread seem to indicate that is:

Does anyone have a definitive answer?

My last response in that thread still holds true.
Use DRD to clone your system disk, and then either update the current disk, with the clone as a backup, or activate and reboot to the clone, update, and test.
One thing with doing it the second way is you can use the white paper to increqase /stand on the clone if you are in an LVM environment

Melvyn,

Thanks. I re-read your response this morning and realized exactly what you meant.

So the conclusion is that there is no way to update the inactive clone while leaving the system up and running 11.23.

It seems to me that this is exactly the sort of thing that DRD would be best for! Oh well.

I did not try this so far, but the guide talks here and there about DRD and update-ux, for example:

The DRD-safe commands are the following:

*

swinstall
*

swremove
*

swlist
*

swmodify
*

swverify
*

swjob
*

kctune
*

update-ux
*

view
...

so it is worth to try.

Hope this helps!
Regards
Torsten.

That's what I was thinking, Torsten. I was hoping that I wouldn't have to be a pioneer here but, if I have to, I will go ahead and take the chance of clobbering the existing system.

I cross checked the install manual for 11.31 and it is telling:

With the HP-UX system administration toolset, Dynamic Root Disk (DRD), you can clone an HP-UX system image to an inactive disk. Then you can:

*

perform system maintenance on the clone while your HP-UX 11i system is online
*

update from an older version of HP-UX 11i v3 to HP-UX 11i v3 March 2009 (Update 4) or later
*

quickly re-boot during off hours once the desired changes have been made
*

utilize the clone for system recovery, if needed

...

http://docs.hp.com/en/5992-6552/ch04s10.html


It describes both, updating the inactive clone or updating the active system and keep the clone as fallback.

Hope this helps!

You CAN use update-ux to go from older 11iv3 system to Update 4 or 5, but NOT from 11.23 to 11iv3.

Re: 11.23 to 11.31 with DRD?

Yes, I've seen that, Melvyn, but if you can run update-ux to get from earlier V3 versions to Update 4/5, it stands to reason (at least in my feeble mind) that you can run update-ux to get from V2 to V3. It may not be supported, but I think it ought to work.

As I said, I was hoping someone else might have tried this previously but I can be the guinea pig if need be.

no, I have tried it and it tells you that this is not supported and will not let you continue.

Re: 11.23 to 11.31 with DRD?

Ahhh! I see. Thanks, Melvyn.

Obviously, you and I have great minds (though mine is also feeble) and the DRD folks do not.
