 Power 5 p570 problem when service processor fails We have had problems when we have lost a service processor on a p570. When it is replaced the codes don't match those in the VPD (? - I think it is that) and we cascade the failure to other components. Basically, it has taken the engineers from IBM and their partner nearly three weeks to get our fairly new machine working again! We were even told to use a bent paper clip to perform a reset! Is anyone else having similar problems with these machines? It does seem like this would be a design rather than a "one off" flaw that would lead to this, but if it is a design flaw I would expect other users to experience it!

This is the first time I've heard of this issue with a power 5 box. I did have a power 4 box (p620) have multiple problems when it arrived a few months ago. It is fixed and no issues now. The box was not yet in production when the problems happened, so it wasn't as big an issue as it could have been if the box was already in production. Mike |

A couple of months ago we lost the service processor on a p5-590. One of the first occurrences worldwide, according to IBM. It took them two days to figure it out. This model has *two* SPs, one primary and one backup, but automatic failover is not yet implemented, so they need to be physically swapped to bring the machine back online (which is what IBM did). Failover will be implemented in firmware SF235, which is not yet available for the p5-590. Dmitri |

| Re: Power 5 p570 problem when service processor fails We've had problems, but nothing unusual. Service Processor problems are nasty, something as simple as a loose SvP cable can cause lots of random and bizarre issues. After out initial setup issues similar to yours it has worked flawlessly (2x570's in house). This system wasn't in production was it? I've never had a 'critical' system get left broken for more than the time it took parts to get couriered in. But yes, that's not a good way to get introduced to the 570.

SP died and after replacement it was discovered that all the VPD was inoperative too. Thanks god, it was not a production system. Roman. |

I am working as a system engineer at one Russian IT company. Last 6 month we have sold about ten pSeries machines to our customers. None of them had such problems. The only thing we had was memory deconfiguration due to predictive error. It was not a failure, but a system guess that memory will fail soon. So it is good point as well, because if memory fails during data transaction it can be a big problem. But in our case we have just replaced a module. |
