Partitioning itanium Server

Allan Umandap — Mon, 11 Apr 2005 20:51:24 GMT

Currently, i have an itanium server running hp-ux 11.23 in single partition. I have 2-cellboard and would like to create another partition. Can anybody help me to do it? Also, if i created the 2nd partition would the i need to assign which DVD drive and tape drive it should use or it would be automatically be assigned upon installation of the OS?

tnx...

Which machine/model do you use.
If you make 2 npars.
The dvd can only be assigned to npar0

Futher more you need 2 core i/o device before you can make 2 npars do you have that?

the command is

parcreate -P -c

If the first partition owns the DVD and tape drive, then the second partition will never see them.

Contact your local HP rep and get a copy of Virtual Machine for Itanium - it appears to be much better than vpars.

Hi Allan,

As of 11.23IA vPars are still not supported on Integrity servers. So nPars are your only "standard" partitioning option at this time. But as noted you need a core-IO for *every* nPar desired. Note you don't need one for every cell board - just for every partiton. So you could have an rx8620 with all four cells installed. If you nParred it 2x2 or 3x1 you'd still only need 2 core-IOs.
But IF you wanted 4 nPars then you'd need the SEU (System Expansion Unit) as that's the only way to get the 3rd & 4th core IOs as well as the 3rd & 4th IO cages.

Rgds,
Jeff

Guys thanks for your replies...

It used to be a two partition machine. Each has its own DVD and tape drive. Well, i reconfigured it and produced just 1 partition with 2 DVD and 2 tape drives. Now, i want to split it again so i could create a test environment. Yes i know vpar is not yet possible for itanium servers so its not an option.

I just like to know that if i proceed with the creation of the 2nd partition, how can i re-assigned its former dvd and tape drive.

May we assume you read and re-read the documentation? Notably:
