模擬更換硬盤以及遷移lp及l(fā)v(筆記)

先介紹幾個命令第一個命令：migratelp命令用途在不同的物理卷上，將已分配的邏輯分區(qū)從一個物理分區(qū)移動到另一個物理分區(qū)。語法migratelpLVname/LPartnumber[/Copynumber]DestPV[/PPartNumber]描述migratelp將指定的邏輯卷LVname的邏輯分區(qū)LPartnumber移動到DestPV物理卷。如果目標(biāo)物理分區(qū)PPartNumber已指定，則使用指定的分區(qū)，否則使用邏輯卷的內(nèi)部區(qū)域策略來選擇目標(biāo)分區(qū)。在缺省情況下，遷移第一個有問題的鏡像副本。可以為Copynumber指定1、2或3的值來遷移一個特殊的鏡像副本。注：在并發(fā)卷組的情況下，必須考慮其他活動的并發(fā)節(jié)點上的分區(qū)使用情況，它是由lvmstat報告。migratelp命令不能遷移條帶化邏輯卷的分區(qū)。安全性要使用migratelp，必須具有root用戶權(quán)限。示例要將邏輯卷lv00的第一個邏輯分區(qū)移動到hdisk1，請輸入：migratelplv00/1hdisk1要將邏輯卷hd2的第三個邏輯分區(qū)的第二個鏡像副本移動到hdisk5，請輸入：migratelphd2/3/2hdisk5要將邏輯卷testlv的第25個邏輯分區(qū)的第三個鏡像副本移動到hdisk7，請輸入：migratelptestlv/25/3hdisk7/100第二個命令：migratepv[

-lLogicalVolume

]SourcePhysicalVolumeDestinationPhysicalVolume...描述migratepv命令將已分配的物理分區(qū)和它們包含的數(shù)據(jù)從SourcePhysicalVolume移到一個或多個其他物理分區(qū)。要限制傳送到特定的物理卷，請在DestinationPhysicalVolume參數(shù)中使用一個或多個物理卷的名稱；否則，卷組中的所有物理卷都可以傳送。所有的物理卷必須在相同的卷組中。指定的源物理卷不能包含在DestinationPhysicalVolume參數(shù)列表中。注:所有的“邏輯卷管理器”遷移函數(shù)都是通過創(chuàng)建涉及的邏輯卷的鏡像，然后重新同步邏輯卷來工作的。然后刪除原始的邏輯卷。如果migratepv命令用于移動包含主轉(zhuǎn)儲設(shè)備的邏輯卷，則在命令執(zhí)行過程中系統(tǒng)將不能夠訪問主轉(zhuǎn)儲設(shè)備。因此，在此執(zhí)行過程中的轉(zhuǎn)儲操作將失敗。要避免這一點，可以在使用sysdumpdev命令之前重新分配一個主轉(zhuǎn)儲設(shè)備，或者在使用migratepv之前確保有從轉(zhuǎn)儲設(shè)備。您可以使用基于Web的系統(tǒng)管理器（wsm）中的卷應(yīng)用程序來更改卷特征。您也可以使用“系統(tǒng)管理接口工具”（SMIT）smitmigratepv快速路徑來運行該命令。注:對于并發(fā)方式卷組，在SSA磁盤上增強并發(fā)方式是活動的或并發(fā)方式是活動的時，migratepv才可以使用。-i從標(biāo)準(zhǔn)輸入中讀取DestinationPhysicalVolume參數(shù)。-lLogicalVolume僅移動已分配到指定的邏輯卷和位于指定的源物理卷上的物理分區(qū)。示例要將物理分區(qū)從hdisk1移動到hdisk6和hdisk7上，請輸入：migratepvhdisk1hdisk6hdisk7將物理分區(qū)從一個物理卷移動到相同卷組內(nèi)的另外兩個物理卷上。要將邏輯卷lv02中的物理分區(qū)從hdisk1移動到hdisk6，請輸入：migratepv

-llv02hdisk1hdisk6只有將那些包含在lv02中的物理分區(qū)從一個物理卷移動到另一個物理卷。實驗嘗試#mklv-tjfs2-ylvbackrootvg1glvback#crfs-vjfs2-dlvback-Ayes-m/backcrfs:0506-909/backfilesystemalreadyexists.#rmfs/back#crfs-vjfs2-dlvback-Ayes-m/backFilesystemcreatedsuccessfully.1048340kilobytestotaldiskspace.NewFileSystemsizeis2097152#mount/back#lslvlvbackLOGICALVOLUME:lvbackVOLUMEGROUP:rootvgLVIDENTIFIER:00046f5f0000d6000000013bfbdc7312.11PERMISSION:read/writeVGSTATE:active/completeLVSTATE:opened/syncdTYPE:jfs2WRITEVERIFY:offMAXLPs:512PPSIZE:256megabyte(s)COPIES:1SCHEDPOLICY:parallelLPs:4PPs:4STALEPPs:0BBPOLICY:relocatableINTER-POLICY:minimumRELOCATABLE:yesINTRA-POLICY:middleUPPERBOUND:32MOUNTPOINT:/backLABEL:/backMIRRORWRITECONSISTENCY:on/ACTIVEEACHLPCOPYONASEPARATEPV?:yesSerializeIO?:NO#lsvg-lrootvgrootvg:LVNAMETYPELPsPPsPVsLVSTATEMOUNTPOINThd5boot122closed/syncdN/Ahd6paging242open/syncdN/Ahd8jfs2log122open/syncdN/Ahd4jfs2122open/syncd/hd2jfs26122open/syncd/usrhd9varjfs2122open/syncd/varhd3jfs2122open/syncd/tmphd1jfs2122open/syncd/homehd10optjfs2122open/syncd/optlg_dumplvsysdump441open/syncdN/Alvbackjfs2441open/syncd/backlv_archjfs2442open/syncd/arch#lspv-lhdisk1hdisk1:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch3300..03..00..00..00/archlg_dumplv4400..04..00..00..00N/Alvback4400..04..00..00..00/back#lspv-lhdisk9hdisk9:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch1100..01..00..00..00/arch#migratelplvback/1hdisk9migratelp:Mirrorcopy1oflogicalpartition1oflogicalvolumelvbackmigratedtophysicalpartition58ofhdisk9.#lspv-lhdisk9hdisk9:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch1100..01..00..00..00/archlvback1100..01..00..00..00/back#lspv-lhdisk1hdisk1:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch3300..03..00..00..00/archlg_dumplv4400..04..00..00..00N/Alvback3300..03..00..00..00/back#lslvlvbackLOGICALVOLUME:lvbackVOLUMEGROUP:rootvgLVIDENTIFIER:00046f5f0000d6000000013bfbdc7312.11PERMISSION:read/writeVGSTATE:active/completeLVSTATE:opened/syncdTYPE:jfs2WRITEVERIFY:offMAXLPs:512PPSIZE:256megabyte(s)COPIES:1SCHEDPOLICY:parallelLPs:4PPs:4STALEPPs:0BBPOLICY:relocatableINTER-POLICY:minimumRELOCATABLE:yesINTRA-POLICY:middleUPPERBOUND:32MOUNTPOINT:/backLABEL:/backMIRRORWRITECONSISTENCY:on/ACTIVE。EACHLPCOPYONASEPARATEPV?:yesSerializeIO?:NO可見將hdisk1上的邏輯卷lvback上第一個lp成功遷移到了hdisk9上，hdisk1上由原來4個lp變成了3個lp,hdisk9上多了個lp。再將其遷回。#migratelplvback/1hdisk1migratelp:Mirrorcopy1oflogicalpartition1oflogicalvolumelvbackmigratedtophysicalpartition117ofhdisk1.#lspv-lhdisk9hdisk9:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch1100..01..00..00..00/arch#lspv-lhdisk1hdisk1:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch3300..03..00..00..00/archlg_dumplv4400..04..00..00..00N/Alvback4400..04..00..00..00/back#做第二個命令的實驗，用migratepv遷移lv中的物理分區(qū)#migratepv-llvbackhdisk1hdisk9#lspv-lhdisk1hdisk1:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch3300..03..00..00..00/archlg_dumplv4400..04..00..00..00N/A#lspv-lhdisk9hdisk9:LVNAMELPsPPsDISTRIBUTIONMOUNTPOINThd10opt1100..00..01..00..00/opthd11100..00..01..00..00/homehd31100..00..01..00..00/tmphd9var1100..00..01..00..00/varhd51101..00..00..00..00N/Ahd26600..00..06..00..00/usrhd41100..00..01..00..00/hd81100..00..01..00..00N/Ahd62200..02..00..00..00N/Alv_arch1100..01..00..00..00/archlvback4400..04..00..00..00/back#開始模擬換盤，這里rootvg兩塊硬盤，插一塊硬盤，執(zhí)行cfgmgr命令，識別出硬盤。假設(shè)壞的是hdisk9，即未啟動盤或者說成不是系統(tǒng)盤，這個好換。#
