RX7620

[Nobody's Hero]

I have a new RX7620 that is hard partitioned.

The server came this way, 2 partitions, each partition has 4 cpu's. "A" has 4 cpu's and "B" has 4 cpu's.

Question.
Can the partition be changed to have 6 CPU's in "A" and 2 CPU's in "B". ?

If I can, will I have to reload the entire system, OS..etc...

The RXt620 is Itanium running 11.23 OS.

Hi,

You can do it if you install VPAR software.
You need to create one hardware partition with to software partitions (VPAR)
The OS must be reinstalled

I was told that Vpar is a thing of the past and Hp is getting away from it, staying with HPAR only.

To split up the cpu's in the way you wish, you need to verify your firmware is updated to the new version, then use Vpars A.04.01 for Itanium and HP-UX 11.23
But to do that, you will first need to destroy your 2nd Npar, then add the cell board into the first Npar, an dthen create Vpars after purchasing the software.

Hard partitions must be on cell board boundaries, so it is not possible to hard partition an rx7620 with 6 CPUs in one and 2 CPUs in the other (assuming you don't have mx2 modules, and even then I think they have to go in in increments of four). You can use vPars on the rx7620, with the May 2005 release of 11.23, and since this was just released, I don't think it is going away anytime soon. Another alternative will soon be the Integrity Virtual Machines, targeted for release in late 2005. This gives you more flexibility but less isolation. While vPars must have dedicated memory and I/O cards, IVM can share I/O cards and devices. The release of IVM might give you the impression that vPars will go away, but I doubt it will in the next couple of years, since there are advantages and disadvantages to each approach to virtualization.

You can create a hard partitioned system only cell by cell, so you can have up to 8 CPUs per cell (depending on version) and only 2 npars in your server.
But you can buy a licence for vpars software and create only 1 npar but different vpars, each with at least 1 cpu, some memory and core i/o (boot disk, lan etc.).
In this case you are able to assign the "unbound" cpus to one or the other vpar online, e.g. you have 2 vpars each with 2 cpus and you can add up to 4 cpus to the running vpar you like.
