Creating a second hard partition on an rp7410 (aka N4000-75)

Creating a second hard partition on an rp7410 (aka N4000-75)

I have an rp7410 that has 6 processors and 16GB of memory with a GSP on one Core I/O board. This system has only one hard partition and I would like to create a second. From all the documentation I've read so far I'm not certain if I have all the hardware needed to do so. I've run `parmgr` as a first attempt and that failed. Can anyone shed some light on what I need to do?

Thank you.

hi john,

rp7410 and N4000-750 is 2 different model.

N4000-750 (A3639C - rp7400) does not support partition.

To check your server model:
# model

If its rp7410, then it is possible creating another partition. Check your existing partition and its status, post the following output:
# parstatus

and take note on how many cell boards you have. This is one of my example:

[Cell]
CPU Memory Use
OK/ (GB) Core On
Hardware Actual Deconf/ OK/ Cell Next Par
Location Usage Max Deconf Connected To Capable Boot Num
========== ============ ======= ========= =================== ======= ==== ===
cab0,cell0 Inactive 4/0/4 4.0/4.0 cab0,bay0,chassis0 yes - -
cab0,cell1 Active Core 4/0/4 2.0/0.0 cab0,bay0,chassis1 yes yes 0

as you can see, rp7410 (cab0) contain cell0 and cell1. In this case, cell0 is inactive and i can create new partition with it.

hard partitions (nPars) are only possible on cell-based systems (not yours), but the N4000 is one of 2 non-cell systems (together with L3000) that supports virtual partitions (vPars).

Have a look on that.

Hope this helps!

I had seen documentation that appeared to say that the rp7410 and the N4000-750 was one-in-the-same, so the response here cleared that up for me nicely.

I've implemented vPars before and will probably do that again.

Thanks!
