Hi Jorge, Sounds like an exciting project!
Regarding quorum server: this is optional; if you have any shared storage between the two nodes you may be able to use that for quorum device instead. A quorum server would be a third machine outside the cluster, and it can act as quorum server to many client clusters. If you can get access to a third machine on the same network you could install quorum server software on it. If other students in the class are doing this same project they could share the same quorum server. Or, one of your nodes could serve quorum to them and one of their nodes could serve quorum to you. Regarding VNIC's: if the only network interface card(s) on each node are for connection to the public network(s) then you can configure virtual network interface cards right on top of them for the private network (also called private interconnect or private transport.) If you happen to have unused physical NIC's you can use them for the private net. You can choose to have scinstall create VNIC's for you by running Custom mode. The smallest hardware configuration would be one NIC and you tell scinstall you only want one private net rather than the standard two, and have scinstall configure a private VNIC on top of the public NIC. Regarding each node not finding the other: please send the output of these commands from each node: # uname -a # ifconfig -a # dladm show-phys # dladm show-vnic # ping <other-node> # svcs -xv # svcs -a | grep cluster # svcs -a | grep rpc/sc hth, --emk Jorge Ruiz Aquino wrote: > Hi Everyone, > I`m attending a class in college about Operating Systems, and as a project we > have to make a cluster with OpenSolaris to test a big application and to show > that is faster in a cluster than a single computer.
