Two or Four Disk Units

I'll preface my question by pointing out that last November, before I came
to work here, the company had two disk crashes. The disks were replaced.
If I run a WRKDSKSTS command, I see two [2] disk drives.

If I run system service tools, I see only two [2] disk drives.

UNLESS I print the Configuration report. Then I see four [4] disk units
listed.

DISK UNIT 6717-050 ? 68-0C8638C 1 L02
DD001



I *think* that the units with the '?' mark (sans The Mysterians) are the
units that crashed last November. Are these truly just phantoms that
someone forget/neglected to remove?



The reason for the question, aside from morbid curiosity, is that the system
is a Model 250, which is limited to four [4] disk units (sans an expansion
unit). I want to add two [2] more disk units (well, not me personally, I
get confused between Philips head and flathead screwdriver). My preference
would be two [2] 17 gb drives, mirrored. Not a great choice, but, since
they decided to defer my proposal for a Power 7 system, I need the space.



Thanks.
