1. Demand

Oracle Linux 6.7 uses udev as asm

/dev/sdb /dev/asm-diskb/dev/sdc /dev/asm-diskc/dev/sdd /dev/asm-diskd/dev/sde /dev/asm-diske/dev/sdf /dev/asm-diskf

2, fault phenomenon

Oracle Linux 6.7 under vmware vshpere5.1, using scsi_id-related commands, no uuid can be seen

3. Treatment method

a. Add records to/etc/scsi_id.config

[root@dfyl rules.d]# echo "options=--whitelisted --replace-whitespace" >> /etc/scsi_id.config

b. Connect via vcenter, then Home-Inventory-Datastore and Datastore Cluster, locate the corresponding storage media, then right-click Datastore Browser

With the VM shutdown, add disk.EnableUUID="TRUE" to the VM file, restart the host, rerun the udev.sh script, and then run the start_udev command

udev.sh (configure udev device mapping and generate udev rule file)

#!/ bin/bashfor i in b c d e f;do echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"">>/etc/udev/rules.d/80-asm.rulesdone

5. Start udev equipment

[root@dfyl rules.d]# start_udevStarting udev: [ OK ]

6. View the corresponding relationship

[root@dfyl rules.d]# ll /dev/asm-disk*brw-rw----. 1 grid asmadmin 8, 16 Apr 12 14:51 /dev/asm-diskbbrw-rw----. 1 grid asmadmin 8, 32 Apr 12 14:51 /dev/asm-diskcbrw-rw----. 1 grid asmadmin 8, 48 Apr 12 14:51 /dev/asm-diskdbrw-rw----. 1 grid asmadmin 8, 64 Apr 12 14:51 /dev/asm-diskebrw-rw----. 1 grid asmadmin 8, 80 Apr 12 14:51 /dev/asm-diskf
