发现硬盘:
# lsdev -Cc disk
hdisk0 Available 08-08-00-4,0 16 Bit LVD SCSI Disk Drive hdisk1 Available 08-08-00-5,0 16 Bit LVD SCSI Disk Drive |
# lspv
hdisk0 00ce898aff3e9f74 rootvg active hdisk1 none None |
重新扫描硬盘：
# cfgmgr –v
查看PV容量是否一致：
# prtconf | grep disk
hdisk0 active 546 445 109..105..13..109..109 + hdisk0 U787A.001.DPM1TZX-P1-T10-L4-L0 16 Bit LVD SCSI Disk Drive (73400 MB) + hdisk1 U787A.001.DPM1TZX-P1-T10-L5-L0 16 Bit LVD SCSI Disk Drive (73400 MB) |
检查PV是否为AIX支持的引导设备（返回值为1说明可以作为引导设备，如返回其他值则此盘不是候选）
# bootinfo -B hdisk
1 |
激活PV，则赋值pvid
# chdev -l hdisk1 -a pv=yes
hdisk1 changed |
# lspv
hdisk0 00ce898aff3e9f74 rootvg active hdisk1 00ce898ab8144cd9 None active hdisk2 none None hdisk3 00ce898a00606e9c None |
把hdisk1加入rootvg
# extendvg rootvg hdisk1（此hdisk1已加入其它卷）
0516-1398 extendvg: The physical volume hdisk1, appears to belong to another volume group. Use the force option to add this physical volume to a volume group. 0516-792 extendvg: Unable to extend volume group. |
强行把hdisk1加入rootvg
# extendvg -f rootvg hdisk1
# lspv
hdisk0 00ce898aff3e9f74 rootvg active hdisk1 00ce898ab8144cd9 rootvg active hdisk2 none None hdisk3 00ce898a00606e9c None |
单镜像，关闭QUORUM,先查看QUORUM的状态：
# lsvg rootvg
VOLUME GROUP: rootvg VG IDENTIFIER: 00ce898a00004c00000001420d0ddd10 VG STATE: active PP SIZE: 128 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 1092 (139776 megabytes) MAX LVs: 256 FREE PPs: 991 (126848 megabytes) LVs: 9 USED PPs: 101 (12928 megabytes) OPEN LVs: 8 QUORUM: 2 (Enabled) TOTAL PVs: 2 VG DESCRIPTORS: 3 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 2 AUTO ON: yes MAX PPs per VG: 32512 MAX PPs per PV: 1016 MAX PVs: 32 LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable |
关闭QUORUM：
# chvg -Qn rootvg
0516-1804 chvg: The quorum change takes effect immediately. |
查看状态：
# lsvg rootvg

建立rootvg所有的lv的镜像-卷组镜像(先查看，1个LPs对应1个PPs,执行命令后，查看1个LPs对应2个PPs)
# lsvg -l rootvg
rootvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT hd5 boot 1 1 1 closed/syncd N/A hd6 paging 4 4 1 open/syncd N/A hd8 jfs2log 1 1 1 open/syncd N/A hd4 jfs2 1 1 1 open/syncd / hd2 jfs2 27 27 1 open/syncd /usr hd9var jfs2 1 1 1 open/syncd /var hd3 jfs2 64 64 1 open/syncd /tmp hd1 jfs2 1 1 1 open/syncd /home hd10opt jfs2 1 1 1 open/syncd /opt |
# mirrorvg -s rootvg

做镜像同步：
# syncvg -v rootvg
在两块盘上创建引导信息，
# lslv -l hd5
hd5:N/A PV COPIES IN BAND DISTRIBUTION hdisk0 001:000:000 100% 001:000:000:000:000 hdisk1 001:000:000 100% 001:000:000:000:000 |
# bosboot -a
bosboot: Boot p_w_picpath is 37849 512 byte blocks. |
# bosboot -ad /dev/hdisk0
bosboot: Boot p_w_picpath is 37849 512 byte blocks. |
# bosboot -ad /dev/hdisk1
bosboot: Boot p_w_picpath is 37849 512 byte blocks. |
更新引导设备顺序，实现单机bos容错，系统从hdisk0进行引导，当hdisk0不可用时将从hdisk1进行引导，以提供单机容错。
# bootlist -m normal –o
hdisk0 blv=hd5 |
# bootlist -m normal hdisk0 hdisk1
# bootlist -m normal –o
hdisk0 blv=hd5 hdisk1 blv=hd5 |
重启系统
# sync
# shutdown -Fr
如果前面步骤执行了quorum关闭的操作，必须重新启动系统之后quorum才会生效。
引导过程检查
# bootinfo -b
