I have two Linux AS5 servers running in cluster mode with two HP procurve switches and MSA 1500 SAN, both the servers have one on-board LAN card.The clustering works well if there is no external uplink connected to procurve switches. The moment uplink is connected the cluster goes down and both the servers stop pinging each other. The SAN storage gets mounted on any of the server randomly. The cluster works well if I remove eth0 from the server configuration even if uplink is there. Is this any problem with linux distribution? -- regards Jasneet Singh Today is a gift, that is why it is called "The Present" -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
