Dear All. "Greetings for the Day !!!" I have two HP DL380 G4 PROLIANT servers configured with HP MSA500 storage and RHEL 3 installed in both the servers. Is there any software inbuilt in REDHAT to configure cluster in RHEL 3. If so please tell me in detail to configure the Cluster in Fail over mode. Thanks in advance !!!! With regards, Piyoo.
