更換SSA RAID陣列中硬盤的步驟.doc

建了RAID的磁盤陣列在使用過程中可能會發(fā)生硬盤出現(xiàn)故障需要更換的情況，本文介紹了安全更換硬盤而不破壞數(shù)據(jù)的詳細步驟。1. 首先需要從RAID定義中邏輯上刪除故障硬盤。執(zhí)行下面的命令：# smit ssaraid- Change Member Disks in an SSA RAID Array- Remove a Disk from an SSA RAID Array2. 屏幕顯示出如下的陣列列表：Change Member Disks in an SSA RAID ArrayMove cursor to desired item and press Enter.Remove a Disk From an SSA RAID ArrayAdd a Disk to an SSA RAID ArraySwap Members of an SSA RAID Array-SSA RAID Array Move cursor to desired item and press Enter. Use arrow keys to scroll. hdisk6 -6010337B163E30K good -2.3GB -RAID-5 array hdisk5 -09523173A02137K good -2.3GB -RAID-5 array F1=Help -F2=Refresh -F3=Cancel F8=Image -F10=Exit -Enter=Do /=Find - n=Find Next -選擇要刪除的硬盤所在的陣列的名稱，在本例中選擇 hdisk6。3. 屏幕顯示如下的信息：Remove a Disk From an SSA RAID ArrayType or select values in entry fields.Press Enter AFTER making all desired changes.-Entry FieldsSSA RAID Manager -ssa1SSA RAID Array -hdisk6Connection Address / Array Name -6010337B163E30K* Disk to Remove -+F1=Help -F2=Refresh -F3=Cancel -F4=ListF5=Reset -F6=Command -F7=Edit -F8=Image F9=Shell -F10=Exit -Enter=Do 按下F4鍵，列出屬于該RAID陣列中的硬盤。 4. 硬盤列表顯示如下：Remove a Disk From an SSA RAID ArrayType or select values in entry fields.Press Enter AFTER making all desired changes.-Entry FieldsSSA RAID Manager -ssa1SSA RAID Array -hdisk6Connection Address / Array Name -6010337B163E30K* Disk to Remove -+-Disk to Remove Move cursor to desired item and press Enter.

You will see a prompt displayed nextto the drive listing when service is set.例:-pdisk0 -AC503429 -00-03-P -1GB SSA C Physical Disk Drive-pdisk1 -AC510D98 -00-03-P -1GB SSA C Physical Disk Drive-pdisk2 -AC510D91 -00-03-P -1GB SSA C Physical Disk Drive-pdisk3 -AC510D96 -00-03-P -1GB SSA C Physical Disk Drive-pdisk4 -AC50374D -00-03-P -1GB SSA C Physical Disk Drive pdisk5 -AC510D91 -00-03-P -1GB SSA C Physical Disk Drive-pdisk6 -AC510DBB -00-03-P -1GB SSA C Physical Disk Drive-pdisk7 -AC510D99 -00-03-P -1GB SSA C Physical Disk Drive6. 物理上拿掉故障硬盤。若不確定是那一塊，可以看到故障硬盤的電源燈旁的黃色檢查燈是亮的。7. 物理上安裝好替換的硬盤。8. 按照步驟5的方法將硬盤從維護模式設(shè)置回普通模式。 9. 邏輯上從系統(tǒng)中刪除舊的硬盤信息，再將新更換的硬盤配置起來：# rmdev -dl pdisk* (其中，pdisk* 為具體的硬盤號，本例中為pdisk5。) # cfgmgr10. 下面需要將新更換的硬盤設(shè)置為陣列的候選盤：# smitty ssaraid- Change/Show Use of an SSA Physical Disk- - 選擇正確的 SSA Raid卡。從列表中選擇正確的硬盤 (屏幕顯示如下)-SSA Physical Disk Move cursor to desired item and press Enter. Use arrow keys to scroll. # SSA physical disks that are members of arrays. pdisk4 -0004AC50374D00D member -n/a -1.1GB -Physical pdisk7 -0004AC510D9900D member -n/a -1.1GB -Physical # # SSA physical disks that are AIX system disks. pdisk5 -0004AC510D9300D system n/a -1.1GB Physical F1=Help - F2=Refresh -F3=Cancel F8=Image -F10=Exit -Enter=Do /=Find -n=Find Next -Make sure the Current Use Parameter is set to Array Candidate Disk onthe next screen (listed below).
