7.rmdev

rmdev -dl 从设备定义状态到预定义状态 或从设备有效状态到预定义状态 rmdev -l 从设备有效状态到自定义的定义状态 也可以使用cfgmgr

8./dev/cd0是cdrom设备

可以用mount -rv cdrfs /dev/cd0 /cdrom

9.设备号

通常在失败时显示在LED中

00 资源附加到处理器 01 资源附加到ISA 04 资源附加到PCI

AB -CD -EF -GH -->端口号 |

PP:物理分区:分配给卷组的物理分区大小

LP:逻辑分区:PP的指针,通过他可以将LV跨越不同的磁盘

LV:逻辑卷 PV:物理卷

VG:卷组:类似表空间

1.QUORUM

每个磁盘上都有一个及以上的VGDA(卷组描述区)

QUORUM也就是说一个卷组中的必须超过>=51%以上的VGDA有效才能使用卷组 通常可以不设置,对于做RAC,或者MIRROR不应该做

2.AIX规定 /dev/hd4 / /dev/hd2 /usr

/dev/hd9var /var /dev/hd3 /tmp

/dev/hd1 /home /proc /proc /dev/hd10opt /opt

/dev/hd6 /pagespace&dump device /dev/hd7 dump device /dev/hd8 /log /dev/hd5 bootlv

3./etc/filesystem 4.mount ... 5.lsfs

查看文件系统 6.lsvg

lsvg -l rootvg 查看卷组中的lv

-bash-2.05b$ lsvg -l rootvg rootvg:
