Good morning, Just curious - are you not using a multipathing software? I'd be surprised if not... In that case you should not use the raw/physical devices in /dev/rdsk, but rather the pseudo-device the multipathing software creates for you. These you can tame a lot more easily, and partition them to your liking. For Solaris and EMC PowerPath for example (which I use a lot), you could create slice 4 (with proper alignment with the array) spanning pretty much all the disk, and assign this to ASM with a wildcard.
