This article mainly introduces Redhat7 Udev how to bind order path equipment, the article is very detailed, has a certain reference value, interested friends must read it!

1. Get the disk UUID:

For disk in `ls / dev/sd* `

Do

Echo $disk

/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=$disk

Done

/ dev/sdb

two。 Generate rules file

Cat / etc/udev/rules.d/99-oracle-asmdevices.rules

3. Load rules Fil

Udevadm control-reload-rules

Udevadm trigger

4. The device information after binding is as follows:

Ls-l / dev/sd*

Brw-rw---- 1 grid asmadmin 8, 16 Aug 29 09:28 / dev/sdb

Brw-rw---- 1 grid asmadmin 8, 32 Aug 29 09:28 / dev/sdc
