ClusterService is a group that "belongs" to the cluster itself. In most instances you will find it that way you describe. It also is a great place for the notifier resource. Normally it is not required. When using Global Clustering (connecting 2 or more clusters for wide area failover), the Wide Area Connector process is in the group along with its IP and NIC resource.
CS has special properties above and beyond normal SGs. It cannot be frozen, is never autodisabled, and it can failover to a frozen system. I am not sure why you would put a NIC proxy in it. Perhaps you plan to put in the NIC and have other SGs use proxies to it. If so, you will not need the Phantom resource normally in a NIC only SG. The IP and web will bring the SG online so the Phantom is only required when the only resource is a NIC (since NIC is not able to bring a SG online by itself). ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of i man Sent: Wednesday, June 25, 2008 8:09 AM To: email@example.com Subject: [Veritas-ha] ClusterService Group Hi, I know Cluster service group hosts vcsweb and webip agent but can somebody exactly explain what the use of Cluster service group. Would I be ble to shut this down for some maintenance operations/testing without affecting other service groups and vcs in whole ? Whats the affect on the system by shutdown of CSG ? I'm also planning to put an nic proxy group in clusterservice gorup , I hope this would not be a bad idea as currently only have vcsweb and webip. Ciao
