A storage service group is thekey and the value of the key can either be 0 or 1.Set the value of the key to 1 to bring the service group onlinewhen the AlternateIo resource comes online and to take theservice group offline when the AlternateIo resource goes offline.Localize the StorageSG attribute of the AlternateIO resourcewith the list of storage service groups that are configured oneach node.AlternateIO altiores1(StorageSG @primary1 = { primary1-strsg1 = 1 }StorageSG @primary2 = { primary2-strsg1 = 1 })NetworkSG attributeThis attribute is a key value pair.
