Hello !

I try to create a new virtual partition from mksysb ( NIM).
Everything goes well till first reboot (just after mksysb is
transfered to partition).

When partition starts - "No os image was detected by firmware. At
least one disk in the bootlist was not found yet"
Bootlist is empty. In sms mode if i try to choose hdisk (scsi device)
i only see :
U9133........-V8-C17-T1 /vdevice/vscsi@30000003
and if I pick it, an error appears :
SELECTED DEVICES WERE NOT DETECTED IN THE SYSTEM


What I did - step by step procedure :
1. [HMC] Dynamically add the virtual scsi adapter to the VIO server
(required "no", slot 17). Save profile, change to default.
2. [HMC] On the virtual partition profile I define an equivalent
virtual SCSI
adapter (required "yes", slot 17).
3. [vio console] Run cfgdev to pick up the the new vhost on the VIO
server.
4. Use the mkvdev command to define a disk to the vhost.
mkvdev -vdev hdisk7 -vadapter vhost10 -dev vhdisk7

lsmap -a shows :
vhost10 U9133.55A.651010H-V2-C17
0x00000008
VTD vhdisk7
LUN 0x8100000000000000
Backing device hdisk7
Physloc U787B.001.DNWD33C-P1-C5-T1-W200600A0B80FB149-
L5000000000000

5. [NIM] define machine, prepare mksysb,
6. [HMC] Activate the virtual partition in SMS. IPL install, configure
network.
7. Installation goes ok. It sees the hdisk !
I have chosen "shrink file system", so at the end of installation
process he ask to increase /tmp fs to 32000.
I do it, and installation finishes without problems.
8. Lpar reboots automatically ... and error appears that he can't find
any hdisk...

help !
