RE: Model 170 DASD

On the 270's, I know it was model/feature dependent. I had a 270-2248 and
concurrent maintenance was not an option. Needed to be up one model/feature
as I recall.

I know on an old 270 I was responsible for, the drive cage supporting
concurrent maint was optional...

The PDF linked to above mentions:
"Small green lights are lit on the front of your system unit when the 2740
disk unit controller is installed. The 2740 disk unit controller enables you
to concurrently replace a disk unit in your system unit."

Yes, I've done the concurrent maintenance approach a couple of times
on my 170. Is that what you meant? You have to be quick, though.
