The SUSE Linux Enterprise Server host requires configuration changes to run failover. The failover solution uses DM-MP.
Before you begin
- You have installed the required packages on your system.
- For Red Hat (RHEL) hosts, verify the packages are installed by running rpm -q device-mapper-multipath
- For SLES hosts, verify the packages are installed by running rpm -q multipath-tools
About this task
By default, DM-MP is disabled in RHEL and SLES. Complete the following steps to enable DM-MP components on the host.
Procedure
- Add the NVMe E-Series device entry to the devices section of the /etc/multipath.conf file, as shown in the following example:
devices {
device {
vendor "NVME"
product "NetApp E-Series*"
path_grouping_policy group_by_prio
failback immediate
no_path_retry 30
}
}
- Configure multipathd to start at system boot.
# systemctl enable multipathd
- Start multipathd if it is not currently running.
# systemctl start multipathd
- Verify the status of multipathd to make sure it is active and running:
# systemctl status multipathd
