Storageworks Issue

[Niceguy3321]

About a month ago, I updated all firmware and drivers for my two different clusters

fast forward to now, i had a strange glitch

i thought it was a power outage that took everything offline, but found out that wasn't the case

both clusters didn't reboot, or anything, but both storage controllers (port 1 and port 2) of two different clusters both went offline at the same time in about the same fashion

was this caused by a bad UPS, or a bad switch\ports?


checking the event log shows me  private interface (cross over heart beat) went down -> then public interface -> slot 1 storage controller -> slot 2 storage controller

After rebooting both clusters, everything came online fine.

I am extremely bothered by this.  Everything was stable for about a month, and then the clusters both puke for no reason at all.

So, back to my original question:  What do you think caused this?  Bad network switch\ports, bad UPS, or bad drivers?

The curve ball for me is that no other servers show that there network interfaces were disconnected during the above times.

 
Thanks in advance for you help!

Cluster 1 is a file cluster:  Storageworks msa 500 g1, and two DL 380 g3's.
Cluster 2 is an exchange cluster:  Storageworks msa 500 g2, and two DL 380 g4's.

Both are running Windows 2003 server enterprise, sp2.

Hey, does these events indicate a problem with the connection to the MSA500 G1s? What kind of connection do you have to them? Just a SCSI cable from each server?
