2 Questions regarding Max CPU's for K210 and Moving nike array???

[Shaun Aldrich]

Hello Everyone,

I have been asked by management these two questions which I am having difficulty in finding out.

1) We currently have two none production systems with nike disk arrays on each. Can you move the nike disk array from one system to the other and interconnect them? If so we would then like to add new drives to the system that no longer has the nike array.

How large of drives would we need to install in the system without the nike array to host a few applications such as AutoSys, Omniback II and a few other products? What might be a safe recommendation where we still have extra room?

2) Does anyone know the Maximum amount of CPU's a K210 & a K570 can hold as I will need to upgrade as soon as possible? Memory would also be an asses?

Thanks for your help..

1) You should be able to, if you dont have system filesystems on them...

2) If I remember right K210 2cpus
K570 4cpus

You can do the vgexport/vgimport to move the nike array to another system.

Drive space could be 2 4 GB drives and 2 36 GB drives. This may be overkill but you mentioned room for expansion and this will provide room plus you can mirror the vg00 drive.

Number of CPUs for K class can be 1-6

Your K210 can have from 1-4 CPU's, Your K570 can have up to 6 CPU's.

You can move your Nikes no problem, but they cant be shared between hosts, have to only be connected to a single host. For your applications anywhere from 4-9Gb drives on them would be fine.

K570 will take 6 cpu's and max of 8Gb memory at HP-UX 11, 3.75Gb at 10.20
K210 will take 4 cpu's and will take 3.75Gb RAm max ( I think)
As for the disc question, I am not sure what exacty you are after, but the size of the discs you need on a node after removing the arrays will depend on the software you are using, number of users etc, basically how much you need to put on the system

Hello Everyone,

Thanks for your responses... I have confirmed that the nike array is not part of the root volume group. However, if the naming convention for the nike array volume group is /dev/vg_nike_00/lvol1 on one system and on the other system it is the same will that not pose a major problem?

When I was to do the vgexport/vgimport after connecting the nike array to the system with the other nike array would you not need to have different volume group/logical volume names? This is a little confusing to say the least for me.

Thanks for your help...

The naming convention will not pose a problem.

When you do the vgexport on the first system, you are removing the LVM definitions for the VG on that system. When you do the vgimport on the new system to bring in the nike, you are defining the VG for the new system.

If you already have a VG on the new system with the same VG name, you can modify the map file (that is created when you do the vgexport) and have the lvol names not conflict with each other.

[Victor BERRIDGE]

If you were to keep the same structure, than you should have to on the 1rst host do a vgexport -m before, so give a name to the mapfile copy the mapfile on the destination host then vgexport your NIKE so the old system is clean, then on your destination host use the mapfile you just copied with th vgimport -m option

[John Palmer]

I assume that you intend to connect the spare nike to a server that already has one and want to retain the data on the nike that's moving.

This is not a problem as when you import the volume group(s) on the nike that's relocating, you can rename them to what you want e.g. vg_nike_01

Shaun, you most definitley can share a NIKE array with two separate hosts. This is provided as an option in a HA environment. Note that you cannot share LUNs between the two hosts - each host will use its own disks in the array independently.

This configuration is called the "Multi-bus Configuration".

If you want more info, let me know.
