OS Upgrade

[Mike Swift]

We need to upgrade a server (N class) from 11.0 to 11.23 and the server has 2 internal 9 gig drives and about 20 9 gig drives in arrays. What would the challenges to do this upgrade?

Thanks

Mike.

Mike,

If I recall correctly, you can't "upgrade" directly from 11.0 to 11.23 - you would have to go to 11.11 first. That being the case and the standard recommendation being to cold install anyway, I would say you would want to cold install 11.23. Actually I wouldn't even bother with 11.23 and go directly to 11.31.

If you can isolate some disk space to do the install on, you can retain your original root volume as a fallback and just vgexport/vgimport all your data volumes into the new root volume - simple as that. If you can't find disk space, you'll have to backup the 11.0 root space in order to have a fallback but you'll still need to vgexport/vgimport your data volumes.

Mike,
As a side note, I would not EVER do an upgrade, unless you have too. A cold install is always a sure fire way to go. Upgrades can go haywire real fast.

also, check your existing hardware against the list of supported devices at 11.23 (or 11.31). as i recall, support for some of the interface cards was dropped in one of those releases. I no longer recall what cards / which releases however.

Thanks for the replies..I have some questions though

1. We have been advised to do Ignite Upgrades (is it viable at all at the first place? from 11.0 to 11.23?)

2. Could you confirm that it is not possible to upgrade from 11.0 to 11.23? can you please provide a reason (or a hp link that says that if possible?)

3. since we have 9 gig disks is this enough to do 11.23 install? (we have 2 9 gig internal desk and 20 9 gig disks on arrays)

Thanks

Mike.

Hi Mike:

If you examine the Installation guide for 11iv2 (11.23) you can see the filesystem sizes that you will need and that it is NOT possible to upgrade from 11.0 to 11.23 directly. Your N-class must be a 64-bit capable server, too.

JRF:

THanks..i also noticed that the link has the following message..

NOTE: HP-UX 11i v2 is not supported on PA-RISC Workstations. HP recommends that PA-RISC Workstation customers use HP-UX 11i v1.

So does this mean that on the nclass it is not recommended to install 11.23?

Thanks

Mike.

sorry again..nclass server is not a PA RISC workstation..Thanks
