The question of whether or not to RESET a down system is a touchy one. I've heard the mantra for years and could not begin to challenge it on technical grounds.
<Sidebar> Two hunters are out in the woods. One accidentally shoots the other. (Any resemblance to U.S. politicians past or present is coincidental.) The shooter calls Emergency in a panic. "Help! I just shot my friend. I think he's dead. What should I do?" "What you do next depends on whether he's really dead. Please make sure." [Pause. BANG!] "OK, I'm sure." <End Sidebar> The point: we've run one form of 'plex' or another for 15 years. We have never required operators to RESET a down system once a wait state is achieved after V XCF OFF. I can't deny the possibility of some comatose I/O operation miraculously coming to life after seconds or minutes of WAIT STATE. I can however attest to the inherent risk of an operator--or a distracted sysprog--going to the trouble of unlocking an LPAR in order to RESET...the wrong image. Until I have (sad) experience to the contrary, I'm inclined to play the published odds: once dead, dead for good. . .

Mark, does this apply to a basic sysplex, too? Or would Ken be safe having automation reply to it? <snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
