Last time I used ODS it was limited to using the normal partition maps ie 8 per disk, which was one reason we opted for veritas. A interesting hybrid I've seen at sites is ODS for the "key" file systems (root, var etc ), and veritas for the rest. In this way, if your system gets itself into a major twist, the main file systems are still in stock standard file system format and can be booted without the need of either ODS or veritas.
