AIX本地磁盘无法做mirror，平衡盘的资源分布，并更换快故障的磁盘
(1)通过errpt查看故障盘
root@zjswsky2:#errpt IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION DCB47997 0102015220 T H hdisk1 DISK OPERATION ERROR
(2)查看本地磁盘组成的rootvg信息
root@zjswsky2:#lsvg rootvg VOLUME GROUP: rootvg VG IDENTIFIER: 00fa515900004c0000000153abd03342 VG STATE: active PP SIZE: 512 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 1116 (571392 megabytes) MAX LVs: 256 FREE PPs: 148 (75776 megabytes) LVs: 16 USED PPs: 968 (495616 megabytes) OPEN LVs: 15 QUORUM: 1 (Disabled) TOTAL PVs: 2 VG DESCRIPTORS: 3 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 2 AUTO ON: no MAX PPs per VG: 32512 MAX PPs per PV: 1016 MAX PVs: 32 LTG size (Dynamic): 1024 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable PV RESTRICTION: none INFINITE RETRY: no DISK BLOCK SIZE: 512 CRITICAL VG: no FS SYNC OPTION: no
(3)查看系统各目录大小
root@zjswsky2:#df -g Filesystem GB blocks Free %Used Iused %Iused Mounted on /dev/hd4 10.00 3.22 68% 18036 3% / /dev/hd2 10.00 6.84 32% 48948 3% /usr /dev/hd9var 5.00 2.10 59% 6806 2% /var /dev/hd3 15.00 4.02 74% 404 1% /tmp /dev/hd1 10.00 6.57 35% 350 1% /home /dev/hd11admin 0.50 0.50 1% 5 1% /admin /proc - - - - - /proc /dev/hd10opt 5.00 4.79 5% 4073 1% /opt /dev/livedump 0.50 0.50 1% 4 1% /var/adm/ras/livedump /dev/lvogg 80.00 50.10 38% 3388 1% /goldengate /dev/lvu01 80.00 22.11 73% 2784979 35% /u01 /dev/saloglv 2.00 2.00 1% 6 1% /salog /dev/nbulv 10.00 3.51 65% 4377 1% /usr/openv
(4)查看各本地磁盘，hdisk0下的目录的pps
root@zjswsky2:#lspv -l hdisk0 hdisk0: LV NAME LPs PPs DISTRIBUTION MOUNT POINT livedump 1 1 00..01..00..00..00 /var/adm/ras/livedump lvogg 160 160 00..00..05..111..44 /goldengate hd11admin 1 1 00..00..01..00..00 /admin lg_dumplv 12 12 00..08..00..00..04 N/A nbulv 2 2 00..00..00..00..02 /usr/openv lvu01 160 160 102..00..00..00..58 /u01 hd8 1 1 00..00..01..00..00 N/A hd4 20 20 00..00..20..00..00 / hd5 1 1 01..00..00..00..00 N/A hd6 32 32 00..32..00..00..00 N/A hd10opt 10 10 00..00..10..00..00 /opt hd3 30 30 00..00..30..00..00 /tmp hd1 20 20 00..20..00..00..00 /home hd2 20 20 00..00..20..00..00 /usr hd9var 10 10 00..00..10..00..00 /var
(5)查看各本地磁盘，hdisk1下的目录的pps
root@zjswsky2:#lspv -l hdisk1 hdisk1: LV NAME LPs PPs DISTRIBUTION MOUNT POINT livedump 1 1 00..01..00..00..00 /var/adm/ras/livedump lvogg 160 160 00..00..05..111..44 /goldengate hd11admin 1 1 00..00..01..00..00 /admin nbulv 18 18 00..00..00..00..18 /usr/openv lvu01 160 160 111..49..00..00..00 /u01 saloglv 4 4 00..00..00..00..04 /salog hd8 1 1 00..00..01..00..00 N/A hd4 20 20 00..16..04..00..00 / hd5 1 1 01..00..00..00..00 N/A hd6 32 32 00..32..00..00..00 N/A hd10opt 10 10 00..00..10..00..00 /opt hd3 30 30 00..00..30..00..00 /tmp hd1 20 20 00..00..20..00..00 /home hd2 20 20 00..00..20..00..00 /usr hd9var 10 10 00..00..10..00..00 /var
(6)rootvg是否做镜像，PVs为2表示做镜像
root@zjswsky2:#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 32 64 2 open/syncd N/A hd8 jfs2log 1 2 2 open/syncd N/A hd4 jfs2 20 40 2 open/syncd / hd2 jfs2 20 40 2 open/syncd /usr hd9var jfs2 10 20 2 open/syncd /var hd3 jfs2 30 60 2 open/syncd /tmp hd1 jfs2 20 40 2 open/syncd /home hd10opt jfs2 10 20 2 open/syncd /opt hd11admin jfs2 1 2 2 open/syncd /admin lg_dumplv sysdump 12 12 1 open/syncd N/A livedump jfs2 1 2 2 open/syncd /var/adm/ras/livedump lvogg jfs2 160 320 2 open/syncd /goldengate lvu01 jfs2 160 320 2 open/syncd /u01 saloglv jfs2 4 4 1 open/syncd /salog nbulv jfs2 20 20 2 open/syncd /usr/openv
(6) /goldengate缩小10G
root@zjswsky2:#chfs -a size=-10G /goldengate Filesystem size changed to 146800640
(7) 查看df -g
root@zjswsky2:#df -g Filesystem GB blocks Free %Used Iused %Iused Mounted on /dev/hd4 10.00 3.22 68% 18036 3% / /dev/hd2 10.00 6.84 32% 48948 3% /usr /dev/hd9var 5.00 2.10 59% 6806 2% /var /dev/hd3 15.00 4.02 74% 404 1% /tmp /dev/hd1 10.00 6.57 35% 350 1% /home /dev/hd11admin 0.50 0.50 1% 5 1% /admin /proc - - - - - /proc /dev/hd10opt 5.00 4.79 5% 4073 1% /opt /dev/livedump 0.50 0.50 1% 4 1% /var/adm/ras/livedump /dev/lvogg 70.00 40.10 43% 3388 1% /goldengate /dev/lvu01 80.00 22.11 73% 2784980 35% /u01 /dev/saloglv 2.00 2.00 1% 6 1% /salog /dev/nbulv 10.00 3.51 65% 4377 1% /usr/openv
(5)查看各PPs信息
root@zjswsky2:#lsvg -p rootvg rootvg: PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION hdisk0 active 558 98 09..51..14..00..24 hdisk1 active 558 90 00..14..10..00..66
(6)尝试做mirror vg对本地磁盘做镜像，存储镜像没必要，存储本身做raid
