AIX: 查看未加入vg的hdisk容量比较常用的命令

如果一个硬盘(hdiskX/pv)已经加入了vg, 那么可以使用lsattr/lscfg等
命令来查看这个硬盘的大小,如:

# lspv
hdisk0          00c54456747d8617                    rootvg          active
hdisk1          00c544667b3e201f                    rootvg          active
...
hdisk13         none                                None

备注: 可以比较清晰的看到hdisk0的容量为300000MB.

但是对于hdisk13这种没有加入到任何vg中的磁盘这种方法就不管用了.

这时可以使用bootinfo -s hdiskX命令看看
# bootinfo -s hdisk13
51530

可以看到这个硬盘hdisk0的大小为50GB
