Re: Virtual Serial Number Question

So, what stops them from running it on more than one at the same time?

VSN can be assigned only within a pool linked to the physical server the partition is, _at the moment you are assigning it_, described on . You cannot assign the same VSN to two partitions on two distinct servers. The VSN is unique to the partition, so I guess (I am not working for IBM; before my retirement a couple of months ago, I was only hoping to see this feature available but no luck) that once it was assigned to a partition, and even if this one was moved to another server with LPM or SRR, it cannot be assigned to another one. When you use LPM or SRR, the partition is created on the target server and _deleted_ on the source server (this is automatic when using SRR when the source server becomes available back after repair).

Hope it helps.

Will there be any other static ID of partitions/logical partitions that the
customer can't change? Or will this be in addition to say, QSRLNBR or
using the QWCRSVAL API?

Jacob,

I got that part, but I'm wondering if a customer has two boxes, can they

run the same virtual serial number on each one?
Yes, they can... but not at the same time. If a partition has a VSN, the
unique way for it to run on another server than the current one, is to
move it with LPM (Live Partition Migration) or SRR (Simplified Remote
Restart). So, at any time, the partition will run on only one server.

Hello Rich and Michael,

No. I happened to screenshot the slides and reviewed them after the
presentation. They included that in the deck under the slide titled "VSN
Considerations".

"Can I share a VSN between multiple partitions? No. A VSN is unique to a
partition. If you want multiple partitions to share the same serial

number,

you will have to use the base (physical) hardware serial number."
