This article mainly shows you "Oracle in asm before how to use udev to bind shared storage", the content is easy to understand, clear, hope to help you solve doubts, the following let Xiaobian lead you to study and learn "Oracle in asm before the use of udev binding shared storage" this article.

1. Use fdisk-l to query the disk on the host under root users. This time, about 4 2T disks are assigned to the host. Due to the influence of multi-path, you can see 8 disks, so you can ignore them and use 4 of them.

# fdisk-l | grep Disk

two。 Edit / etc/udev/rules.d/99-oracle-asmdevices.rules file

# more 99-oracle-asmdevices.rules

# ASM_DISKS

KERNEL== "sddlma [a Murd]", OWNER= "grid", GROUP= "asmadmin", MODE= "0660"

3. Restart udev

/ sbin/start_dev

4. View the bound shared storage

[root@DC8VFJNK2-R730 dev] # ls-l sddlmaa

Brw-rw---- 1 grid asmadmin 251, 0 Oct 12 15:37 sddlmaa

[root@DC8VFJNK2-R730 dev] # ls-l sddlmab

Brw-rw---- 1 grid asmadmin 251, 16 Oct 12 15:37 sddlmab

[root@DC8VFJNK2-R730 dev] # ls-l sddlmac

Brw-rw---- 1 grid asmadmin 251, 32 Oct 12 15:37 sddlmac

[root@DC8VFJNK2-R730 dev] # ls-l sddlmad

Brw-rw---- 1 grid asmadmin 251, 48 Oct 12 15:37 sddlmad
