I hope someone has experienced this problem before and can help. I have a P730 (8231-E2D) which is fitted with 8 IBM SAS disks on 2 separate SISSAS controllers. The disk type is ST9146853SS (Seagate SAS 146Gb).
The problem occurs when I try to install the VIO server software at 2.2.3. It fails to correctly install and the file systems (if they load at all) are corrupted with a lot of the .exe files missing!
I load it from a mksysb on the NIM server with the SPOT created from the mksysb. I have used the same mksysb this morning to build a VIO server on a P750 and it worked correctly
Perhaps there is a firmware pre-requisite. I'm not sure that there really are .exe files on AIX (that VIOS is built on) anyway.
If you have just bought a licence for VIOS, then you should be able to talk to IBM about the problems. If you don't have a licence, IBM will want to talk to you!
I have investigated further and have learnt a very useful but painful lesson. When you look at the P730 from the HMC you see two SAS controllers, 1 on P1/C8 and the other on P1/C18/T1. I stupidly assumed these were 2 seperate controllers but no it appears they are the same controllers and all disks are fitted to both! Where is the sense in that? Come on IBM answer that question!
