I cant help you here...
I dont have such a subsystem, I only once had to help a friend in a bank which had one a long time ago...( I deal with mostly HDS, and had some clarion in older days...)
look at this:
HP 12H
You will see why it is called autoraid... and why I believe the main concern I see is your unique boot disk...
Now since you have no HP sysadmin, dont you think its an opportunity for you to get to know bit more on HP-UX and its administration anyway it will always be a pleasure giving you help/advice and maybe one day it will be my turn asking some help about oracle issue or SAS issue...
If you need more
feel free to ask
Best regards
