快速检测多路径对应的DISK的脚本

该脚本为检测rac中disk多路径的情况，在添加磁盘进asm时候要格外小心，需要反复验证多路径对应磁盘，加错盘的情况时有发生，这脚本可以帮助DBA在添加磁盘时候判断对应lun的多路径的情况。

如果aix需要把sd改成rlv，把多路径的命令更换。

脚本为：

#!/bin/ksh
for disk in `ls /dev/sd*`
do
disk_short=`basename $disk`
wwid=`scsi_id -g -s /block/$disk_short`
if [ "$wwid" != "" ]
then
  echo -e "Disk:" $disk_short "\tWWID:" $wwid
fi
done

结果为：


Disk: sda       WWID: 3600601602b702d006218b7de8130e111
Disk: sdaa      WWID: 3600601602b702d000652b695c648e111
Disk: sdab      WWID: 3600601602b702d000752b695c648e111
Disk: sdac      WWID: 3600601602b702d007f2a73fbc648e111
Disk: sdad      WWID: 3600601602b702d007e2a73fbc648e111
Disk: sdae      WWID: 3600601602b702d006218b7de8130e111
Disk: sdaf      WWID: 3600601602b702d0036d7cf191241e111
Disk: sdag      WWID: 3600601602b702d0037d7cf191241e111
Disk: sdah      WWID: 3600601602b702d0038d7cf191241e111
