Hi all, We had a power supply fall over recently (but we have redundancies setup, so the power supply above took over), but if I hadn't been looking for the manual in the back of the library I wouldn't have seen the lights or fans off. How long can these power supplies last when feeding two drives? How do you any of you guys know if you have a power failure in your 3584? Is it normal for library units to not report these kinds of failures?
By virtue of host connection, libraries may send error information to the OS error handler, for logging in that OS's error log. The 3584 manual UltraScalable Tape Library Planning and Operator Guide describes the opportunity to use SNMPTRAP to monitor your library. The Redpaper at http://www.redbooks.ibm.com/redpapers/pdfs/ redp3822.pdf talks of using TapeAlert to get hardware problem alerts. A surprising number of large sites do not monitor their hardware, though outages can be very impacting. If any List member sites do not yet, by all means embark upon implementing that missing link in availability assurance. It's not that difficult, and having that further awareness of what's going on is very reassuring. Richard Sims
