P4300 G2 complete meltdown when switch comes online

[Jim Silvia]

I had a similar problem. The switch wasn't showing any errors. But performance was horrible and the storage manager kept going down. This was for a new install.

Look at the logs for each node. Hardware->Log Files. There's a hist.ifconfig.log - download that check for any interface errors.

Once we found this we saw a large # of errors that the NSM nic was reporting that wasn't seen on the switch. We moved the CAT5 to new gigabit ports on the same switch (module 4208) and the newer module resolved the problem. No more errors and great performance.
