AIX环境通过增加lv大小来增加ASM diskgroup 大小----非常规方法
先交代环境:
AIX 7.1
Oracle/ASM 11.2.0.3 单实例
今测试环境需要将ASM中flashdg的大小增大到35G(目前10G),diskgroup是基于在vg中以raw方式划分出来的lv创建的。
由于是测试环境仅通知AIX管理员,AIX管理员直接通过smit lv 增加fsflashdglv的pp个数,添加之后再操作系统中可以发现lv是增大了,但是flashdg1没有增大。下面来描述整个过程。
-----此为非常规方案,常规方案应该是新建lv后,以add disk的方式来增加flashdg的大小。
系统管理员增加fsflashdglv的大小后:
root@seven1:/.root>lsvg -l datavg
datavg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
fsoraapplv jfs2 280 280 1 open/syncd /oraapp
loglv00 jfs2log 1 1 1 open/syncd N/A
fsdatadglv raw 160 160 1 open/syncd N/A
fsdatadg1lv raw 240 240 2 open/syncd N/A
fsflashdglv raw 280 280 2 open/syncd N/A

发现flashdg并没有增大。
利用Oracle的kfed工具获取asmdisk的信息:
grid@seven1:/home/grid>kfod disk=all

disk header block显示此时asm diskgroup 中的lv确实是10G,并非35G。最后想是不是grid端还会有其他操作?
问了一圈朋友,没问出来,最后问了一个大神同事,他告诉我试试将disk resize。
反正是测试环境,试试呗:
SQL>alter diskgroup FLASHDG1 resize disk FLASHDG1_0000 size 35840M;
Diskgroup altered.
貌似可以了,赶紧看看:
grid@seven1:/home/grid>asmcmd lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name

Ok,此时flashdg1 认到35G了。
