Look at the invoice when the box was purchased or placed on maintenance. On an individual drive, on the DS6800 you might look for a log file for when that dasd was last created. Lots of log files there.
But there is no date, that I'm aware of, on the header, vtoc, allocation map, etc. If you have a performance monitor, with history being kept, you might find some indication there. Same goes for a security product. Perhaps a comment in the IOCP deck. Other than that, find the old grey hair person that was there when it was installed <G>.
