                     [metachk: sanity-check your RAID]

                       Which platforms are supported?

metachk is designed to check Solstice DiskSuite configurations, and is thus
only available for Solaris 2.x (aka SunOS 5) and later releases.

I know that DiskSuite 1.0 is available for SunOS 4, but it is a different
beast on that platform and would require a different approach, so SunOS 4
is not supported.

  ------------------------------------------------------------------------

Tested Configurations

metachk has been tested on every working combination of
Solaris 2.4, 2.5, 2.5.1,
2.6, 7, 8 and 9 with DiskSuite 2.0.1, 3.0, 4.0, 4.1, 4.2 and 4.2.1,
with all possible types of RAID metadevice, including shared disksets.
It even does the right thing if DiskSuite is not installed!

However...

metachk currently does not recognise "soft-partitions" (introduced with
DiskSuite 4.2.1 on Solaris 8): metadevices made up of soft-partitions
are not fully checked.

metachk currently does not recognise "MPxIO"-style device-names on Solaris 9:
metadevices made up from such components are not fully checked.
