AIX连存储

本文参照一位前辈的文档，做了一些补充，对aix连存储做了如下笔记。

 

由于演练需要，生产系统中做importvg和exportvg这类管理工作。 大致命令如下

首先在原系统umount fs, varyoffvg。

 

root@aixbk/:>lsvg -l datavg:   (查看挂载vg下的文件系统)
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
670bak_lv           jfs2       1000  1000  1    open/syncd    /app
loglv04             jfs2log    1     1     1    open/syncd    N/A

 

root@aixbk/:>lsvg -p datavg      
datavg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk107          active            8143        7142        1629..628..1628..169

root@aixbk/:>df -k
Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on
/dev/hd4          1048576    969532    8%     2304     1% /
/dev/hd2          2293760    947968   59%    27876     5% /usr
/dev/hd9var        131072     98676   25%      483     2% /var
/dev/hd3          1114112   1017744    9%      126     1% /tmp
/dev/hd1          8388608   1652208   81%    27609     2% /home
/proc                   -         -    -         -     -  /proc
/dev/hd10opt       655360    202908   70%     3202     2% /opt
/dev/670bak_lv   262144000 119481344   55%    82909     1% /app

 

root@aixbk/:>umount /app           （>lsfs下看所有需mount文件）

 

root@aixbk/:>varyoffvg datavg 

 

root@aixbk/:>exportvg datavg

 

 

接下来在另一点上操作

 

# importvg -y 'datavg' hdisk3
0516-022 : Illegal parameter or structure value.
0516-780 importvg: Unable to import volume group from hdisk3.

# lspv
hdisk0          00ce7f5a91dbe2d9                    rootvg          active
hdisk1          00cdc94bdce1d31e                    None
hdisk2          none                                None
hdisk3          none                                None

发现hdisk3的pvid还是none

 

# chdev -l hdisk3 -a pv=yes
hdisk3 changed

# lspv
hdisk0          00ce7f5a91dbe2d9                    rootvg          active
hdisk1          00cdc94bdce1d31e                    None
hdisk2          none                                None
hdisk3          003adc7c7f56a3e8                    None

# importvg -y 'datavg' hdisk3
datavg

# lsvg -l datavg     (查看datavg挂载文件)
datavg:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
670bak_lv           jfs2       1000  1000  1    closed/syncd  /app
loglv04             jfs2log    1     1     1    closed/syncd  N/A

# lsvg -p datavg     （查看datavg磁盘的情况）
datavg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk3            active            8143        7142        1629..628..1628..162
8..1629

# mount /app

# df -k       （查看aix挂载的情况）
Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on

至此，完成了。
