Checking RAID-1 Mirror Status in OS X El Capitan (now that DiskUtility is toast for RAID)

With the release of OS X El Capitan, Apple has removed RAID functionality and destroyed useful features and added wanton bugs in Disk Utility. Accordingly, MPG recommends that users of DiskUtility RAID turn to SoftRAID.

While MPG strongly recommends SoftRAID for RAID at this point, there are ways to work with RAID at the command line. The most basic of these, particularly useful for checking RAID-1 mirror status, is to list the current status*.

* Creating and manipulating RAID volumes via command line is not for the faint-hearted, particularly when there are many disks present -- one typo and *poof* goes the wrong volume. Use SoftRAID.
