DiskSuite 4.2.1 work with Solaris 2.7?

I understand that DiskSuite is supposed to come (unbundled) with Solaris 2.7, however I can’t seem to spot it in either my 5/98 or 11/99 versions. I do have DiskSuite 4.2.1 on a Sol 8 CD, but anyone here know if that would that run on my Solaris 2.7 (11/99) system? Or if you can tell me the package name of it to add in 2.7 that would be great.

Thanks!
David
