First partition the two disks using format as you usually would. Make a very small (just a 5 megabytes or so) partition on the beginning of each disk for the DiskSuite metadevice state database, and a very large partition to contain the actual data.

Use the metadb command to create the metadevice state database on the two small parititions. See the man page for details.

Once you have done that you can create a striped or concatenated metadevice using metainit, e.g. for striped you might use metainit d1 1 2 /dev/dsk/c1t2d0s1 /dev/dsk/c1t3d0s1 (presuming you used slice 0 for your metadb and slice 1 for data).

Then you can create your filesystem on /dev/md/rdsk/d1 as you normally would.

Hopefully that should be enough to get you started.

would it be metainit d1 1 2 /dev/dsk/c1t2d0s1 /dev/dsk/c1t3d0s1

OR

metainit d1 2 1 /dev/dsk/c1t2d0s1 1 /dev/dsk/c1t3d0s1

The first would give you a 'striped' device... i.e. 1 stripe with 2 columns.

The second would give youa 'concatenated' device.... i.e. 2 stripes with 1 column. Of course a 1 column stripe isn't a stripe at all, but that's the way DiskSuite deals with it.
