a MP card reset question

hi,my 8420 console can not response,so i want to reset the MP. but i found that the 1000baseT NIC on the MP card is configured to transmit heartbeat message in the cluster environment(2rp820+mcsg).so my question is that:when i reset the mp card, the 1000baseT NIC will be shortly disabled or not? if it is disabled,i think,the heartbeat message will be interrupted,and it will affect the cluster which i can not afford.

thank you !

Re: a MP card reset question

I'm not going to answer your question directly but will say that if you have only one heartbeat LAN then your cluster is a disaster waiting to happen. If your cluster can't survive the failure/reset/replacement (on the fly) of any one component then you've done it wrong. The failure of a heartbeat LAN should be an expected, tolerated event and should not trigger a package/node failover.
If it ain't broke, I can fix that.

Re: a MP card reset question

resetting the MP should not necessarily affect the system LAN port, but care should be taken

"my 8420 console can not response"

What does this mean? Can you connect to the MP? Can you get a response from the MP and no results from the console?

Maybe a running process is "blocking" the console. Check this.

The MP resides on the same board like the core LAN and SCSI - a reset should not affect other components (do not pull the card!).

Hope this helps!
