I don't think we've ever had to take one. The PSW restart dump has worked here. We had to do one of those when we had a sick DS8000. I guess if the dump space had been on that device, then SA would have been useful.
It would, however, take an act of god to ship an actual tape out of the datacenter. We would have to load that back to DASD anyway.

We don't use stand-alone dump very often, and the list of tape drives to use had gotte= n badly out of date.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, woul= d this be worth a SHARE requirement? z/OS apparantly requires stand-alone dumps more often that VM. When a z/O= S 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?
