SC10 bus controller failure
We had an issue with a customer regarding an SC10. Basically they have two SC10s mirrored against each other. Once, one SC10 started beeping and it was reporting a failed bus controller. We removed the bus controller and reinstalled the same one and everything worked fine surprisingly! until a few days ago. It had been working without problems for like 1-2 months. It is exhibiting the same problem now.
Is there a known issue regarding this? Any other comments/help?
Thanks in advance,
Vince

Re: SC10 bus controller failure
The configuration is as follows.
There're 4 SCSI HBAs in the system and 2 HBA are connected directly to each BCC of SC10#1 and the other 2 HBAs are to each BCC of SC10#2.
Both SC10s are configured for full bus operation.
Our plan was to have SC10s mirrored against each other but we encounted the almost same problem as you described.
We replaced BCCs in an attempt to isolate the problem but failed.
Later, we took a close look at SC10 manual and decided to have SC10s configured as split-bus configuration.
Since then, the problem was disappeared.
I hope this helps,

Re: SC10 bus controller failure
We went on site today and restarted the SC10 and worked fine again!! Now, we exchanged the "faulty" bus controller with one from the other SC10. If the same one fails, then it's the bus controller which is bad, if the other (i.e. the one in which the "faulty" SC10 was) fails, it means that the problem is more awry.
Any more comments and help are welcome. I promise I will assign points when the case is solved.
Thanks,
Vince

Re: SC10 bus controller failure
The same BCC failed again, i.e. the one which we put at the top. We are going to replace it.
Thanks to everyone who participated in this thread. Case Closed.
