At my previous company, the only time I had seen the 3K crash was when
it lost LDEV 1. I know of no major system that really tolerates losing
the drive(s) that contain the OS, at least not for long.

Here, we have seen a party who must remain nameless crash our 3Ks by:
using a file transfer that does stuff it shouldn't; copying all data the
data group to another group (in spite of having archive utilities
available) with a third party utility, consuming all available space,
leaving a corrupt NM KSAM file, then trying to purge that file; and a
few other interesting things. Suffice it to say that I regard these
events as abnormal in the extreme; it's the hardware that I expect to
see go bad.
