Installing and configuring Multipath Multipath under Oracle Linux 6.9

1.Installing the Multipath tool

# yum–y Install Device-mapper Device-mapper-multipath

2. Set boot from boot

# Chkconfig MULTIPATHD on

3. Open Multipath

# mpathconf--enable

or use the full command: mpathconf--enable--find_multipaths y--with_multipathd y--with_chkconfig y

4. Open Service

# Service MULTIPATHD Restart

5. View Status

# MULTIPATH-LL

The following status indicates that the boot is healthy


6. create partition: Fdisk/dev/mapper/data01 or PARTED/DEV/MAPPER/DATA01

7 . View multi-Path generated DM disk

# ls-lrt/dev/mapper/

DATA01 is a disk; DATA01P1 is the partition I created

8, the system default is not DATA01 such a name, but similar to MPATHB such a name, you can modify the/etc/multipath.conf to customize the name

The value of the Wwid can be obtained by the MULTIPATH-LL command
