IBM伺服器更換rootvg故障磁碟操作指南
1 Rootvg做映象
1.1 Rootvg做映象要求
在安裝完作業系統，配完應用後，我們一般要給rootvg做映象，做rootvg映象的硬碟必須和rootvg的硬碟空間大小相同，轉速相同的同一型號內建SCSI硬碟。可透過下面這些命令來確認：
lsdev -Cc disk 確定主機中有幾塊硬碟，有幾塊內建硬碟
# lsdev -Cc disk [IBMP740-1:root:/]#lsdev -Cc disk hdisk0 Available 00-00-00 SAS Disk Drive hdisk1 Available 00-00-00 SAS Disk Drive hdisk2 Defined 07-00-02 EMC CLARiiON FCP LUNZ Disk hdisk3 Defined 07-00-02 EMC CLARiiON FCP LUNZ Disk hdisk4 Defined 05-00-02 EMC CLARiiON FCP LUNZ Disk hdisk5 Defined 05-00-02 EMC CLARiiON FCP LUNZ Disk hdisk6 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk7 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk8 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk9 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk10 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk11 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk12 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk13 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk14 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk15 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk16 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk17 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk18 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk19 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk20 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk21 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk22 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk23 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdiskpower0 Available 05-00-02 PowerPath Device hdiskpower1 Available 07-00-02 PowerPath Device hdiskpower2 Available 05-00-02 PowerPath Device
lspv 確定主機中那塊內建硬碟沒有被VG使用
# lspv hdisk0 0057908c7251c07a rootvg hdisk1 0057908cea9403a2 None hdisk2 005d03fc9859db6c datavg [IBMP740-1:root:/]# lspv hdisk0 00f7ac3dfb20ed5a None hdisk1 00f7ac3d60694e5e rootvg active hdisk10 none None hdisk11 none None hdisk12 none None hdisk13 none None hdisk16 none None hdisk17 none None hdisk18 none None hdisk19 none None hdisk20 none None hdisk21 none None hdisk22 none None hdisk23 none None
lsattr -El 確定hdisk0與hdisk1硬碟的大小一致

lscfg -vpl 確認硬碟的Part number或FRU Number號是否一樣，如一樣說明硬碟型號一樣。

Device Type: block由上可知，hdisk0與hdisk1型號、大小一致，可以做rootvg映象。
#一般基本上除了haview ，netwiew ( Tivoli)的包以外，所有的hacmp的包都要安裝。
1.2 配製rootvg映象
首先將hdisk1硬碟加入到rootvg中
# extendvg rootvg hdisk1
0516-014 linstallpv: The physical volume appears to belong to another
volume group.
005d027c00004c00
0516-631 extendvg: Warning, all data belonging to physical
volume hdisk1 will be destroyed.
extendvg: Do you wish to continue? y(es) n(o)? y
# lspv
hdisk0 0057908c7251c07a rootvg
hdisk1 0057908cea9403a2 rootvg
hdisk2 005d03fc9859db6c datavg
給rootvg做映象
# mirrorvg rootvg hdisk1
0516-1124 mirrorvg: Quorum requirement turned off, reboot system for this
to take effect for rootvg.
0516-1126 mirrorvg: rootvg successfully mirrored, user should perform
bosboot of system to initialize boot records. Then, user must modify
bootlist to include: hdisk0 hdisk1.
給hdisk0、hdisk1分別做引導分割槽
# bosboot -ad hdisk0 bosboot: Boot image is 15092 512 byte blocks. # bosboot -ad hdisk1 bosboot: Boot image is 15092 512 byte blocks.
設定系統的引導順序為hdisk0、hdisk1
# bootlist -m normal hdisk0 hdisk1 # bootlist -m normal -o hdisk0 blv=hd5 pathid=0 hdisk1 blv=hd5 pathid=0
設定Quorum為Disable.，這樣保證了一旦硬碟壞了一塊，rootvg還是能正常啟來。
# chvg -Qn rootvg 0516-1804 chvg: The quorum change takes effect immediately.
執行lsvg命令確認rootvg已做映象，可看到除了lg_dumplv之外所有其它LPs和PPs的對應關係為1對2的關係。

2 更換rootvg中的故障盤
這裡假設hdisk0硬碟故障，需要更換。
2.1 確定hdisk0硬碟故障
首先執行errpt命令檢視錯誤日誌,如果hdisk0損壞的話，會有很多hdisk0的報錯。

執行lsvg 確認映象丟失，可看到LPs和PPs的對應關係變為11對應。

執行lspv -l hdisk0命令會報錯，確認hdisk0硬碟故障。
2.2 更換hdisk0硬碟
首先將hdisk0硬碟從rootvg中unmirror
# unmirrorvg rootvg hdisk0
0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c '
as root user to clear the boot record and avoid a potential boot
off an old boot image that may reside on the disk from which this
logical volume is moved/removed.
0516-1132 unmirrorvg: Quorum requirement turned on, reboot system for this
to take effect for rootvg.
0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform
bosboot of system to reinitialize boot records. Then, user must modify
bootlist to just include: hdisk1.
執行chpv -c hdisk0命令清除掉boot記錄
# chpv -c hdisk0
0301-108 mkboot: Unable to read file blocks. Return code: -1
0516-1248 chpv: mkboot failure
# reducevg rootvg hdisk0
0516-016 ldeletepv: Cannot delete physical volume with allocated
partitions. Use either migratepv to move the partitions or
reducevg with the -d option to delete the partitions.
0516-884 reducevg: Unable to remove physical volume hdisk0.
這是因為 lg_dumplv在rootvg預設情況下沒有做映象的原因，只建立在hdisk0上,現在要修改主dump目錄為null（空目錄)
# lslv -l lg_dumplv lg_dumplv:N/A PV COPIES IN BAND DISTRIBUTION hdisk0 008:000:000 100% 000:008:000:000:000 # sysdumpdev -P -p /dev/sysdumpnull primary /dev/sysdumpnull secondary /dev/sysdumpnull copy directory /var/adm/ras forced copy flag TRUE always allow dump FALSE dump compression ON type of dump traditional
從rootvg中刪除hdisk0硬碟
# reducevg -d rootvg hdisk0
0516-914 rmlv: Warning, all data belonging to logical volume
lg_dumplv on physical volume hdisk0 will be destroyed.
rmlv: Do you wish to continue? y(es) n(o)? yes
rmlv: Logical volume lg_dumplv is removed.

2.3新增新硬碟到rootvg中,並做映象
拔出hdisk0故障硬碟，插入新硬碟。執行以下操作將新硬碟加入到rootvg中
# cfgmgr -v

建立引導映像
# bosboot -ad hdisk0 bosboot: Boot image is 53276 512 byte blocks. # bosboot -ad hdisk1 bosboot: Boot image is 53276 512 byte blocks.
改變引導區引導順序
# bootlist -m normal hdisk0 hdisk1
檢視引導順序
# bootlist -m normal -o hdisk0 blv=hd5 pathid=0 hdisk1 blv=hd5 pathid=0
# chvg -Qn rootvg 0516-1804 chvg: The quorum change takes effect immediately.
//-Q：確定卷組在丟失其物理卷的限額後，VG是否保持活動；-n：保持活動，預設為：-y。
重新建立dump
# mklv -t sysdump -y lg_dumplv rootvg 16 hdisk0 lg_dumplv
修改主dump device:
# sysdumpdev -Pp /dev/lg_dumplv primary /dev/lg_dumplv secondary /dev/sysdumpnull copy directory /var/adm/ras forced copy flag TRUE always allow dump FALSE dump compression ON type of dump traditional # lsvg -l rootvg rootvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT hd5 boot 1 2 2 closed/syncd N/A hd6 paging 33 66 2 open/syncd N/A hd8 jfs2log 1 2 2 open/syncd N/A hd4 jfs2 40 80 2 open/syncd / hd2 jfs2 10 20 2 open/syncd /usr hd9var jfs2 10 20 2 open/syncd /var hd3 jfs2 20 40 2 open/syncd /tmp hd1 jfs2 10 20 2 open/syncd /home hd10opt jfs2 196 392 2 open/syncd /opt hd11admin jfs2 10 20 2 open/syncd /admin fwdump jfs2 3 6 2 open/syncd /var/adm/ras/platform lg_dumplv sysdump 16 16 1 open/syncd N/A livedump jfs2 1 2 2 open/syncd /var/adm/ras/livedump fslv00 jfs2 40 80 2 closed/syncd /u01
