2.2.2InstallingClusterServices
ThisscenariocoversatwonodeWindows2008R2Cluster.Theproceduresassumethatyou
arefamiliarwithWindows2008Cluster.Therefore,theyfocusonspecificrequirementsfor
attachingtoXIV.
FormoreinformationaboutinstallingaWindows2008Cluster,see:
http://technet.microsoft.com/en-us/windowsserver/bb310558.aspx
Toinstallthecluster,completethesesteps:
1. OntheXIVsystemmainGUI,selectHostsandClusters.Createaclusterandputboth
nodesintotheclusterasdepictedinFigure 2-28.

Inthisexample,anXIVclusternamedclu_solmanwascreatedandbothnodeswere
placedinit.
2. MapalltheLUNstotheclusterasshowninFigure 2-29.

AllLUNsaremappedtotheXIVcluster,butnottotheindividualnodes.
3. Setupacluster-specificconfigurationthatincludesthefollowingcharacteristics:

4. OnNode1,scanfornewdisks.Then,initialize,partition,andformatthemwithNTFS.The
followingrequirementsareforsharedclusterdisks:
Thesedisksmustbebasicdisks.
ForWindows2008,youmustdecidewhethertheyareMasterBootRecord(MBR)
disksorGUIDPartitionTable(GPT)disks.
