需要在虚拟机中部署rac测试环境，创建虚拟机后无法查看到wwid

 
[root@db1 ~]# for i in `cat /proc/partitions |awk {'print $4'} |grep sd`; do echo "Device: $i WWID: `/usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/$i` "; done |sort -k4
Device: sda1 WWID:  
Device: sda2 WWID:  
Device: sda3 WWID:  
Device: sda4 WWID:  
Device: sda5 WWID:  
Device: sda6 WWID:  
Device: sda WWID:  
Device: sdf WWID:  
Device: sdc WWID:  
Device: sdd WWID:  
Device: sdb WWID:  
Device: sde WWID:  
Device: sdh WWID:  
Device: sdg WWID:  
Device: sdi WWID:

在虚拟机上增加参数

 

 

 增加disk.EnableUUID = "TRUE"后重启虚拟机

重启后查询正常显示了

[root@db1 ~]# for i in `cat /proc/partitions |awk {'print $4'} |grep sd`; do echo "Device: $i WWID: `/usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/$i` "; done |sort -k4
