Cluster shared disks

I am trying to build test cluster setup to VMWare server. But when I create new partition to shared disk other node will see that partition only after I will reboot the server. This is also same thing if I will drop file to formated disk which is seen by both of the servers.

Here is my configuration for shared disks

diskLib.dataCacheMaxSize = "0"

scsi1.sharedBus = "virtual"

disk.locking = "false"

scsi1.present = "TRUE"

scsi1:0.mode = "persistent"

scsi1:1.present = "TRUE"

scsi1:1.fileName = "..\SHARED\lun2.vmdk"

scsi1:1.writeThrough = "FALSE"

scsi1:1.mode = "independent-persistent"

scsi1:1.deviceType = "disk"

scsi1:1.redo = ""

scsi1:2.present = "TRUE"

scsi1:2.fileName = "..\SHARED\lun3.vmdk"

scsi1:2.writeThrough = "FALSE"

scsi1:2.mode = "independent-persistent"

scsi1:2.deviceType = "disk"

scsi1:2.redo = ""

scsi1:3.present = "TRUE"

scsi1:3.fileName = "..\SHARED\lun4.vmdk"

scsi1:3.writeThrough = "FALSE"

scsi1:3.mode = "independent-persistent"

scsi1:3.deviceType = "disk"

scsi1:3.redo = ""

scsi1:4.present = "TRUE"

scsi1:4.fileName = "..\SHARED\lun5.vmdk"

scsi1:4.writeThrough = "FALSE"

scsi1:4.mode = "independent-persistent"

scsi1:4.deviceType = "disk"

scsi1:4.redo = ""
