RE: Distribute IBM i on available disk units Was: 70GB load source and 5 other drives

Rob,

At this time, I'm only using the host and guest LPARs for creating and testing DSLO images.
I'm the only user on these LPARS, so no performance issues.
I'm keeping it simple, 1 NWS.
However, things can change overnight, I want to have a good understanding of the pros/cons with multiple NWS.
When you added additional NWS, did you also have to do any HMC config changes?

Paul

Depends on the guest.
One has ~8 Domino servers. Each of these servers is clustered on to at least two other servers.
One has only 1 Domino server and it sits in our DMZ as another cluster of our DMZ Domino servers One has 1 Domino server and a full set of Infor's software for testing.

Neither has a whale of a lot of active users.

We went with guesting so that with scattering each lpar gets 20 arms.
That, and if we add more we do not have to add more raid controllers.

This is the first time the biggest one is guested. It used to be the host. Now we've gone to a dedicated host lpar.

The others used to have just one storage space and seemed rather slow.

Rob,

I'm not sure if you previously stated, what is this guest LPAR used for?

Paul.

I'm digging what you're saying there. I'm no stranger to TRCASPBAL.

At which point do you run:
STRASPBAL TYPE(*ENDALC)
of the load source?

1: After Task 8: Restore the operating system, beginning
with ƒ oTask 1: Starting to restore the
operating systemƒ ?

2: In the middle of the task 8 above? If so, at which step?

When?

If i is hosting i, I thing I would elect to attempt to run with
no drives in *ENCALC status until I actually see some sort of a
performance issue where high I/Os to the load source can be
clearly identified as the culprit.

At that time, I would run STRASPBAL *ENDALC for UNIT(1) followed
by a STRASPBAL *MOVDTA.

Other options could be to run a TRCASPBAL followed by a
STRASPBAL *USAGE to rearrange "cold" data. This would be in the
hope the hot load source becomes warm.
