metatool was created as a knee-jerk reaction to Veritas creating the old VxVA (tin can style) GUI. VxVA worked quite well and metatool has never been a brilliant tool.
Anybody with any experience/sense would be better to ignore metatool and stick with the command line - it really is not difficult.
It is not in with the more recent versions so get used to the command line.
The man pages are all pretty will documented with good examples.
That is because metatool was removed. You really don't need it.
iostat and format will tell you about the disks but they will not give you details regarding the state of the metadevices. Just stick with metastat and metastat -p.
