更換交換機(jī)操作流程

聲明：交換機(jī)切換，在存儲(chǔ)方面不需要做任何動(dòng)作，要做的動(dòng)作都在交換機(jī)和主機(jī)上。一：備份存儲(chǔ)配置文件，導(dǎo)出二：備份交換機(jī)相關(guān)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：服務(wù)器備份相關(guān)信息1，DISK,，F(xiàn)CS，VG，PV，F(xiàn)S。如下圖所示：2，HDLM軟件里頭的鏈路狀態(tài)。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：新的交換機(jī)就位，光纖線標(biāo)識(shí)。該過(guò)程要注意線的位置，標(biāo)識(shí)清楚，在新的交換機(jī)上占用的端口號(hào)，回頭要插入存儲(chǔ)過(guò)來(lái)的光纖線，主機(jī)過(guò)來(lái)的光纖線，事先一定規(guī)劃好，以免到時(shí)出亂。五：交換機(jī)切換下面分三種情況更換交換機(jī)，可以根據(jù)實(shí)際情況采取相應(yīng)方式：（一）：在線更換交換機(jī)該方式不停應(yīng)用，生產(chǎn)可以繼續(xù)，但前提是一定要注意鏈路的冗余方式，至少2路，位于不同的交換機(jī)上。仔細(xì)核對(duì)主機(jī)里頭的HDLM軟件鏈路情況，刪除先要更換的交換機(jī)所在的鏈路。1，如下，在每臺(tái)主機(jī)上執(zhí)行如下命令。確保另一鏈路的正常運(yùn)行。FORAIXHDLMFORAIX2，此時(shí)系統(tǒng)單路運(yùn)行，在插拔光纖線的時(shí)候，一定要注意，不能將剩下的一路offline，否則，應(yīng)用會(huì)停，影響生產(chǎn)。3，更換一路的交換機(jī)，重新cfgmgr，識(shí)別鏈路正常后，更換另一路的交換機(jī)，方式如上。重新cfgmgr。識(shí)別新的硬件，硬盤。確保鏈路正常。驗(yàn)證應(yīng)用。（二）：離線更換交換機(jī)，主機(jī)不重啟1，停生產(chǎn)應(yīng)用2，varyoffvg3，刪除外接HDS的所有設(shè)備，兩路全部刪除掉命令如下：在每臺(tái)主機(jī)上執(zhí)行如下命令，刪除2個(gè)fscsi，一般是fscsi0和fscsi1，兩路全部刪除5.8HDLMFORAIX5.9以上HDLMFORAIX更換兩路的交換機(jī)，重新cfgmgr，識(shí)別新的硬件，硬盤。確保鏈路正常。（三）：離線更換交換機(jī)，主機(jī)重啟1，停生產(chǎn)應(yīng)用2，varyoffvg3，物理更換兩路的交換機(jī)4，主機(jī)重啟，自動(dòng)掃描新的硬件，確保兩路鏈路正常六：驗(yàn)證，起服務(wù)，測(cè)試數(shù)據(jù)驗(yàn)證五中的后兩種方式需要如下動(dòng)作，第一種方式不需要。varyonvg起應(yīng)用驗(yàn)證數(shù)據(jù)七：風(fēng)險(xiǎn)性評(píng)估，最優(yōu)方式選取在步驟五中，提到了三種方式更換交換機(jī)，就風(fēng)險(xiǎn)性方面，建議采用（二）離線更換交換機(jī)，主機(jī)不重啟，但如果主機(jī)數(shù)量較多，不能一一在主機(jī)執(zhí)行相關(guān)的HDLM命令，則可以采用（三）離線更換交換機(jī)，主機(jī)重啟，該方式徹底，一次性到位。不好處在于主機(jī)重啟會(huì)耽誤時(shí)間，有的主機(jī)重啟可能需要漫長(zhǎng)的等待時(shí)間，還可能重啟后報(bào)硬件錯(cuò)誤，這要注意。下面輸出實(shí)際操作中的命令解析，采用（二）離線更換交換機(jī)，主機(jī)不重啟，該情況為HDLM5.8forAIX系統(tǒng)下：僅供可以參考#lspvhdisk0005d0a1fhdisk10051eace80ae4a55rootvgactivehdisk20051eace88486bf5Nonehdisk3005d420de099d1d9Nonehdisk6noneNonehdisk7noneNonedlmfdrv00051eace292ce720datavgdlmfdrv10051eacedc82eeb0datavghdisk8noneNonedlmfdrv20051eace42322b8adatavghdisk10noneNonedlmfdrv30051eacee480c7d2datavghdisk12noneNonehdisk13noneNonehdisk14noneNonehdisk15noneNone#lsdev-Ccdiskdlmfdrv0AvailableHDLMDriverdlmfdrv1AvailableHDLMDriverdlmfdrv2AvailableHDLMDriverdlmfdrv3AvailableHDLMDriverhdisk0Available1S-08-00-8,016BitLVDSCSIDiskDrivehdisk1Available1S-08-00-9,016BitLVDSCSIDiskDrivehdisk2Available1S-08-00-10,016BitLVDSCSIDiskDrivehdisk3Available1S-08-00-11,016BitLVDSCSIDiskDrivehdisk4Defined1H-08-01OtherFCSCSIDiskDrivehdisk5Defined1H-08-01OtherFCSCSIDiskDrivehdisk6Available11-08-01OtherFCSCSIDiskDrivehdisk7Available11-08-01OtherFCSCSIDiskDrivehdisk8Available1H-08-01OtherFCSCSIDiskDrivehdisk9Defined11-08-01OtherFCSCSIDiskDrivehdisk10Available1H-08-01OtherFCSCSIDiskDrivehdisk11Defined11-08-01OtherFCSCSIDiskDrivehdisk12Available1H-08-01OtherFCSCSIDiskDrivehdisk13Available1H-08-01OtherFCSCSIDiskDrivehdisk14Available11-08-01OtherFCSCSIDiskDrivehdisk15Available11-08-01OtherFCSCSIDiskDrive#cd/usr/D*/bin#./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.Operat
