IBM服务器系统盘更换后检查,IBM服务器更换rootvg故障磁盘操作指南
1 Rootvg做鏡像
1.1 Rootvg做鏡像要求
在安裝完操作系統(tǒng)，配完應(yīng)用后，我們一般要給rootvg做鏡像，做rootvg鏡像的硬盤(pán)必須和rootvg的硬盤(pán)空間大小相同，轉(zhuǎn)速相同的同一型號(hào)內(nèi)置SCSI硬盤(pán)。可通過(guò)下面這些命令來(lái)確認(rèn)：
lsdev -Cc disk 確定主機(jī)中有幾塊硬盤(pán)，有幾塊內(nèi)置硬盤(pán)

Device Type: block由上可知，hdisk0與hdisk1型號(hào)、大小一致，可以做rootvg鏡像。
#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 配制rootvg鏡像
首先將hdisk1硬盤(pán)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做鏡像
# 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(dǎo)分區(qū)
# bosboot -ad hdisk0
bosboot: Boot image is 15092 512 byte blocks.
# bosboot -ad hdisk1
bosboot: Boot image is 15092 512 byte blocks.
設(shè)定系統(tǒng)的引導(dǎo)順序?yàn)閔disk0、hdisk1
# bootlist -m normal hdisk0 hdisk1
# bootlist -m normal -o
hdisk0 blv=hd5 pathid=0
hdisk1 blv=hd5 pathid=0
設(shè)定Quorum為Disable.，這樣保證了一旦硬盤(pán)壞了一塊，rootvg還是能正常啟來(lái)。
# chvg -Qn rootvg
0516-1804 chvg: The quorum change takes effect immediately.
執(zhí)行l(wèi)svg命令確認(rèn)rootvg已做鏡像，可看到除了lg_dumplv之外所有其它LPs和PPs的對(duì)應(yīng)關(guān)系為1對(duì)2的關(guān)系。
# lsvg -l rootvg

2 更換rootvg中的故障盤(pán)
這里假設(shè)hdisk0硬盤(pán)故障，需要更換。
2.1 確定hdisk0硬盤(pán)故障
首先執(zhí)行errpt命令查看錯(cuò)誤日志,如果hdisk0損壞的話，會(huì)有很多hdisk0的報(bào)錯(cuò)。

做rootvg鏡像
# mirrorvg rootvg hdisk0
0516-306 getlvodm: Unable to find volume group root in the Device
Configuration Database.
0516-1200 mirrorvg: Failed to mirror the volume group.
創(chuàng)建引導(dǎo)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(dǎo)區(qū)引導(dǎo)順序
# bootlist -m normal hdisk0 hdisk1
查看引導(dǎo)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后，VG是否保持活動(dòng)；-n：保持活動(dòng)，默認(rèn)為：-y。
重新創(chuàng)建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:
