使用Udev管理asmdisk执行/sbin/scsi_id不显示UUID

文章来自：Itpub-warehouse客栈

不知道啥原因,死活显示不了UUID,执行结果是啥也不显示:

[root@udev ~]# /sbin/scsi_id -g -u -s /dev/sdc
[root@udev ~]# 
[root@udev ~]#

VMware的版本是：VMware-workstation-full-10.0.3-1895310

OS的版本是：CentOS 6.5

没有uuid貌似没法配置udev rules文件,不过在一个哥们的帮助下最后通过这样的方式实现的,通过udevinfo命令获取分区的信息,可以利用分区中的这2项信息    SYSFS{start}=="63"和SYSFS{size}=="16771797"来代替uuid唯一标识这个设备:

[root@udev ~]#  udevinfo -a -p /sys/block/sdc/sdc1  #若此处提示bash: udevinfo: command not found则需要手动使用yum install udev命令安装udev
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

于是我创建的udev rules文件内容如下:

[root@udev rules.d]# pwd
/etc/udev/rules.d
