The only use made of VM's stand-alone dump that I can recall in my 33 years 
with VM was to take a dump of a TPF system. PSW Restart always worked when we 
needed to force a dump. We simply had to teach the operators the sequence Store 
Status, System Reset, PSW Restart. They often substituted System Reset Clear.

I have been doing VM for over 22 years and have NEVER done a stand-alone
dump.

We were asked to update our stand-alone dump procedures. We don't use 
stand-alone dump very often, and the list of tape drives to use had
gotten 
badly out of date.

We discovered that z/OS can take a stand-alone dump to disk.  We get
more 
involved in DASD address changes than in tape address changes (we have
to 
move the data), so we would find it easier to keep a list of DASD 
addresses up-to-date. We run "lights-out" data centers, so operations 
would prefer not to have to mount a tape half-way across the country.

Is there some way to take a stand-alone dump to DASD for VM? If not,
would 
this be worth a SHARE requirement?

z/OS apparantly requires stand-alone dumps more often that VM. When a
z/OS 
system fails, it "varies itself out of the plex" -- at which point our 
operations is instructed to take a stand-alone dump. 

I'm not sure when we really need a VM stand-alone dump. Usually a PSW 
restaret will get us a dump. How often do you use stand-alone dumps?
