Summary

Thank you for everybody who replied !

Martin hepworth answered:
Solaris 7 only recognises this much of IDE drives. You need to upgrade
to SOlaris 8 to solve this...

Peter Stokes answered:
According to previous posts U10 can only support 32Gb disks, anything higher
and it goes back to a default size. Have not seen any work around, so please
let me know if you find one. I believe it has to do with the boot rom.

Sunmanager answered:
I think this was on the list last week and it was determined that Sun does
not offer or guarantee support for over 25gb or some size limitation
thereabouts on the Ultra 10.
