声明：交换机切换，在存储方面不需要做任何动作，要做的动作都在交换机和主机上。一：备份存储配置文件，导出二：备份交换机相关信息所用到命令如下：SwitchshowZoneshowConfiguploadCfgshow例如：SW4_CONFIG:admin>configuploadProtocol(scp,ftp,local)[ftp]:ftpUserName[user]:rootPassword:configUploadcomplete:Allconfigparametersareuploaded三：服务器备份相关信息1，DISK,，FCS，VG，PV，FS。如下图所示：2，HDLM软件里头的链路状态。如下所示：#./dlnkmgrview-sysHDLMVersion:05-80-/AServicePackVersion:LoadBalance:on(rr)SupportCluster:ElogLevel:3ElogFileSize(KB):9900NumberOfElogFiles:2TraceLevel:0TraceFileSize(KB):1000NumberOfTraceFiles:4PathHealthChecking:on(30)AutoFailback:offReservationStatus:on(2)IntermittentErrorMonitor:offHDLMManagerVerWakeupTimeAlive05-80-/A2010/11/1117:59:56HDLMAlertDriverVerWakeupTimeElogMemSizeAlive05-80-/A2010/11/1117:58:554000HDLMDriverVerWakeupTimeAlive05-80-/A2010/11/1117:58:54LicenseTypeExpirationPermanent-KAPL01001-ITheHDLMcommandcompletednormally.Operationname=view,complet9#./dlnkmgrview-luProduct:9500VSerialNumber:4951LUs:4iLUHDevNameDevicePathIDStatus0000dlmfdrv2hdisk8000004Onlinehdisk14000005Online0003dlmfdrv3hdisk10000006Onlinehdisk15000007Online0006dlmfdrv0hdisk6000000Onlinehdisk12000001Online0007dlmfdrv1hdisk7000002Onlinehdisk13000003OnlineKAPL01001-ITheHDLMcommandcompletednormally.Operationname=view,complet9#./dlnkmgrview-pathPaths:000008OnlinePaths:000008PathStatusIO-CountIO-ErrorsOnline317229790PathIDPathNameDskNamee00000008.11.0000000000021100.0006HITACHI.DF600F.4951000000108.1H.0000000000021100.0006HITACHI.DF600F.4951000000208.11.0000000000021100.0007HITACHI.DF600F.4951100000308.1H.0000000000021100.0007HITACHI.DF600F.4951100000408.1H.0000000000021100.0000HITACHI.DF600F.4951200000508.11.0000000000021100.0000HITACHI.DF600F.4951200000608.1H.0000000000021100.0003HITACHI.DF600F.4951300000708.11.0000000000021100.0003HITACHI.DF600F.49513四：新的交换机就位，光纤线标识。该过程要注意线的位置，标识清楚，在新的交换机上占用的端口号，回头要插入存储过来的光纤线，主机过来的光纤线，事先一定规划好，以免到时出乱。五：交换机切换下面分三种情况更换交换机，可以根据实际情况采取相应方式：（一）：在线更换交换机该方式不停应用，生产可以继续，但前提是一定要注意链
