LUN are Logical units, you dont need more than 1 AFAIK. the problem
most probably is that you have only 1 disk ARM therefore limiting the
total IOps of the system. Are you using the 2 onboard disks? Does the
blade have SAS or HBA cards? can you hook it up to a storage via FC,
SAS or iSCSI? With more hard info we could see where the botleneck
lies...

best regards,
Roberto

We have a V7R1 i5 running on a blade.  2 LPAR (test and dev) Once we went live with users we noticed it was a bit sluggish.  We have since found out the BP configured 1 LUN for 600GB of disk in ASP 1 in Dev LPAR.

Can we add more LUN to ASP 1?
Can we add more disk to ASP 1 and add more LUN? How?
Seems to me you could add more disk and more LUN as once you ran low on disk you would have to add disk anyway.
