Systemd-udev-settle timing out

This document (7022681) is provided subject to the disclaimer at the end of this document.

Environment


SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2)

Situation

4 ibmvfc npiv devices assigned but only 3 paths show up instead of 4 in the multipath output.

Resolution

Increase timeout for the kernel command line parameter.
    rd.udev.event-timeout=300

Steps to add option:
1. Append option in the file /etc/default/grub
    GRUB_CMDLINE_LINUX_DEFAULT=   rd.udev.event-timeout=300
2. grub2-mkconfig -o /boot/grub2/grub.cfg
3. reboot

Cause

The default rd.udev.event-timeout=180 seconds and was causing a timing issue where systemd-udev-settle timed out.
