AIX：从LVM中回收磁盘
在AIX上，回收LVM中的磁盘会经历这么几个阶段：
1. 停掉目标上的应用与服务
2. 文件系统：取消挂载
3. VG：删除LV
4. VG：删除PV
5. PV：删除PV
6. 回收磁盘
——————————————————————
首先，确认要移动的是那些LV
然后[……]

AIX：0516-792 /usr/sbin/extendvg: Unable to extend volume group.
该错误是在AIX上扩展LVM的时候发生的，具体场景如下。
我们从另一台终止服务的AIX分区上，将LUN划分到了目标分区后，重新扫描设备，得到了新的PV：【hdisk31】

AIX：【Machine Serial Number】以及巡检信息查询
需求如题，具体实现如下：
服务器型号：

1 2 3 |
root@AIX_Me:/ # prtconf | grep "System Model" System Model: IBM,9117-MMA root@AIX_Me:/ # |
服务器序列号：

操作系统版本：

AIX：文件大小限制（fsize）
在AIX中，用户对文件系统的资源使用是有默认限制的。
该值默认是：1 GB
如下：

fsize，就是用户对文件系统的使用大小限制。
–> -1，表示无限制
–> 2097151，限制：1G = 1024 MB[……]
AIX – error：chfs: 0506-932 Can not extend a JFS file system with nbpi = 4096
今天，AIX扩容的时候遇到了如题所示的报错，具体如下：

1 2 3 4 |
root@AIX-ME:/ # chfs -a size=+800G /dev/ora_backup chfs: 0506-932 Can not extend a JFS file system with nbpi = 4096 and frag = 4096 past 134217728 (512 byte blocks). root@AIX-ME:/ # |
看看这个时候的LV状态：
|
1 2 3 |
root@AIX-ME:/ # lsvg -l datavg | grep backup ora_backup jfs 1 1 1 closed/syncd /oracle_backup root@AIX-ME:/ # |
可以按照这种方式重新创建LV：
