解決AIX下識別HDS磁盤陣列多路徑問題

./解決AIX下識別HDS磁盤陣列多路徑問題公司有臺日立HDSAMS2003磁盤陣列,基本還沒怎么使用,于是嘗試分配了4個500G的LUN給一臺測試服務(wù)器,都做了冗余,每塊盤都有4條路徑,分配好后在AIX識別出來了,但每塊盤都重復(fù)了4次。因?yàn)槭且郧笆褂玫亩际荌BM的陣列,沒發(fā)現(xiàn)過有這樣的問題,于是發(fā)貼求助新劃的磁盤陣列,lspv顯示重復(fù)了4次/club/thread-78460-1-1.html通過查詢資料確定了是多路徑的問題,需要用到HDLML軟件,印象中聽日立原廠的工程師提到過,于是聯(lián)系日立原廠工程師拿到了安裝介質(zhì)與license,并在指導(dǎo)下解決了問題,以下是我根據(jù)記錄的日志整理的步驟。1問題磁盤陣列使用的是日立HDSAMS2003,RAID之前就做好了,現(xiàn)在我分配了4個500G的LUN給一臺AIX服務(wù)器使用,但在AIX識別時居然重復(fù)了4次[test2:root:/]lspvhdisk000c48a56795bc09drootvgactivehdisk100c48a566bbc5382rootvgactivehdisk200c48a562bbcd401Nonehdisk300c48a562bbe131fNonehdisk400c48a562bbe139bNonehdisk500c48a562bbe1422Nonehdisk600c48a562bbcd401Nonehdisk700c48a562bbe131fNonehdisk800c48a562bbe139bNonehdisk900c48a562bbe1422Nonehdisk1000c48a562bbcd401Nonehdisk1100c48a562bbe131fNonehdisk1200c48a562bbe139bNonehdisk1300c48a562bbe1422Nonehdisk1400c48a562bbcd401Nonehdisk1500c48a562bbe131fNonehdisk1600c48a562bbe139bNonehdisk1700c48a562bbe1422None[test2:root:/]lspathEnabledhdisk0sas0Enabledhdisk1sas0Availableses0sas0Availableses1sas0[test2:root:/]lsdev-Ccdiskhdisk0Available03-08-00SASDiskDrivehdisk1Available03-08-00SASDiskDrivehdisk2Available02-01-02OtherFCSCSIDiskDrivehdisk3Available02-01-02OtherFCSCSIDiskDrivehdisk4Available02-01-02OtherFCSCSIDiskDrivehdisk5Available02-01-02OtherFCSCSIDiskDrivehdisk6Available02-01-02OtherFCSCSIDiskDrivehdisk7Available02-01-02OtherFCSCSIDiskDrivehdisk8Available02-01-02OtherFCSCSIDiskDrivehdisk9Available02-01-02OtherFCSCSIDiskDrivehdisk10Available06-01-02OtherFCSCSIDiskDrivehdisk11Available06-01-02OtherFCSCSIDiskDrivehdisk12Available06-01-02OtherFCSCSIDiskDrivehdisk13Available06-01-02OtherFCSCSIDiskDrivehdisk14Available06-01-02OtherFCSCSIDiskDrivehdisk15Available06-01-02OtherFCSCSIDiskDrivehdisk16Available06-01-02OtherFCSCSIDiskDrivehdisk17Available06-01-02OtherFCSCSIDiskDrive2解決過程2.1license上傳license文件HDSHDLMAIX.plk到/var/tmp,并改名為hdlm_license[test2:root:/]cd/var/tmp[test2:root:/var/tmp]ls.oracledpid2.logoradiag_oraclesnmpdv3.logHDSHDLMAIX.plkhostmibd.logslp_srvreg.locksnmpmibd.logaixmibd.loginstallpbx-2228732-031811161323.logsnmpd.log[test2:root:/var/tmp]mv"HDSHDLMAIX.plk"hdlm_license[test2:root:/var/tmp]ls.oraclehdlm_licenseoradiag_oraclesnmpdv3.logaixmibd.loghostmibd.logslp_srvreg.locksnmpmibd.logdpid2.loginstallpbx-2228732-031811161323.logsnmpd.log2.2上傳HDLM軟件鏡像文件并加載鏡HDLM軟件為一個ISO鏡像文件,包含各個平臺的HDLM軟件,還從來沒在AIX系統(tǒng)中加載過ISO文件,于是馬上上網(wǎng)查詢,終于找到了一個最簡單的辦法mountISO鏡像：#loopmount-idlmglm_072001.iso-o"-Vcdrfs-oro"-m/mntunmountISO鏡像：#fuser-cuk/mnt#unmount/mnt2.3安裝ODM[test2:root:/var/tmp]cd/mnt[test2:root:/mnt]lsAutorun.infHDLM_AIXHDLM_SolarisHDLM_WindowsPSPindex.htmlrr_movedContents_list.txtHDLM_LinuxHDLM_VMwareHGLMhcmdslicense2installux.sh[test2:root:/mnt]cdHDLM_AIX[test2:root:/mnt/HDLM_AIX]ls.tocAIX_ODMDLManager.mpio.bffhdlmtoolnetmdm_sample[test2:root:/mnt/HDLM_AIX]cdAIX_ODM[test2:root:/mnt/HDLM_AIX/AIX_ODM]lsHTC_ODMXP_ODMreadme.txt[test2:root:/mnt/HDLM_AIX/AIX_ODM]cdHTC*[test2:root:/mnt/HDLM_AIX/AIX_ODM/HTC_ODM]lsHTCODM3.tarHTC_readme.txt[test2:root:/mnt/HDLM_AIX/AIX_ODM/HTC_ODM]mkdir/tmp/hdlm[test2:root:/mnt/HDLM_AIX/AIX_ODM/HTC_ODM]cp*.tar/tmp/hdlm[test2:root:/mnt/HDLM_AIX/AIX_ODM/HTC_ODM]cd/tmp/hdlm[test2:root:/tmp/hdlm]lsHTCODM3.tar[test2:root:/tmp/hdlm]tarxBpf*[test2:root:/tmp/hdlm]lsHTCODM3.tarHTC_FC_ODM_5001IHTC_FC_ODM_5005UHTC_FC_ODM_50521UHTC_FC_ODM_50522UHTC_FC_ODM_50523U[test2:root:/tmp/hdlm]smittyinstallp通過以上步驟即完成了ODM的安裝[test2:root:/tmp/hdlm]lslpp-l|grep-idlm[test2:root:/tmp/hdlm]lslpp-l|grep-ihitachiHitachi.aix.support.rteCOMMITTEDAIXSupportforHitachiDisk2.4安裝HDLM[test2:root:/tmp/hdlm]cd/mnt[test2:root:/mnt]lsAutorun.infHDLM_AIXHDLM_SolarisHDLM_WindowsPSPindex.htmlrr_movedContents_list.txtHDLM_LinuxHDLM_VMwareHGLMhcmdslicense2installux.sh[test2:root:/mnt]cdHDLM_AIX[test2:root:/mnt/HDLM_AIX]smittyinstallp通過以上步驟即完成HDLM的安裝[test2:root:/mnt/HDLM_AIX]lslpp-l|grep-idlmDLManager.mpio.rteCOMMITTEDDynamicLinkManagerDLManager.mpio.rteCOMMITTEDDynamicLinkManager2.5重新識別磁盤[test2:root:/mnt/HDLM_AIX]cfgmgr[test2:root:/mnt/HDLM_AIX]lsdev-Ccdiskhdisk0Available03-08-00SASDiskDrivehdisk1Available03-08-00SASDiskDrivehdisk2Available02-01-02OtherFCSCSIDiskDrivehdisk3Available02-01-02OtherFCSCSIDiskDrivehdisk4Available02-01-02OtherFCSCSIDiskDrivehdisk5Available02-01-02OtherFCSCSIDiskDrivehdisk6Available02-01-02OtherFCSCSIDiskDrivehdisk7Available02-01-02OtherFCSCSIDiskDrivehdisk8Available02-01-02OtherFCSCSIDiskDrivehdisk9Available02-01-02OtherFCSCSIDiskDrivehdisk10Available06-01-02OtherFCSCSIDiskDrivehdisk11Available06-01-02OtherFCSCSIDiskDrivehdisk12Available06-01-02OtherFCSCSIDiskDrivehdisk13Available06-01-02OtherFCSCSIDiskDrivehdisk14Available06-01-02OtherFCSCSIDiskDrivehdisk15Available06-01-02OtherFCSCSIDiskDrivehdisk16Available06-01-02OtherFCSCSIDiskDrivehdisk17Available06-01-02OtherFCSCSIDiskDrivehdisk18Available02-01-02HitachiDiskArray<Fibre>hdisk19Available02-01-02HitachiDiskArray<Fibre>hdisk20Available02-01-02HitachiDiskArray<Fibre>hdisk21Available02-01-02HitachiDiskArray<Fibre>可以看到hdisk18至h
