10.20 to 11.0 upgrade on a D-class server.

[Bruce Troutman]

I am assisting a sys admin on performing an upgrade from 10.20 to 11.0 on a D box. Could someone point me in the right direction on locating some documentation on:

1. Disk space needed. I found a document from '98' that recommended 2GB of disk space and 64mb RAM.

/usr - 120 MB additional
/var - 5 MB additional
/opt - 55 MB additional

2. Gotchya's
3. Some sort of cookbook on the process
4. What files need to be checked Pre/Post installation.

Hello:

Well, I would if possible do a cold install of HP-UX 11.
I had to ugrade a D class at a client, in which they didnt want that, and they also had only a 4gig drive for the OS, in which they didnt want to purchase something bigger, so the client pretty much controled my options.

And it prrduced head aches, drive space was a HUGE factor, not very easy to extend what was already a mess.

What I can tell you is, if you have to upgrade, and cant do a cold install, make sure you make an Ignite Tape, you may need it, and also you can extend your drives to the required amounts, but I would add more than the required for some room to grow in var.

I know there is a document here, but I dont know it off hand, try a seach for the upgrade, or someone can post you the actual link.

Also, if upgrading make sure you remove the 10.x patches, run a cleanup -i. after wards.
The book, actually has some good steps to follow if you can get it, its Installing and updating HP-UX 11.0.

the upgrade for me took 6 hours, once it started.

Oracle 8.x had problems, with some library files, in which did get corrected in time.

If you can, do the cold install, unless your like I was where I had no choice. Also, if you are under a support contract with HP, or have an HP rep, you can call them, they will provide you with a nice checklist and a listing of files you should backup separately.

best to you.
