Type/Severity
Product Enhancement Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An enhanced device-mapper-multipath package is now available.
Description
The device-mapper-multipath package provides tools to manage multipath
devices by instructing the device-mapper multipath kernel module what to do.
Bugs fixed in this update include:
- device-mapper-multipath did not work correctly with GNBD devices
- multipath didn't correctly read /var/lib/multipath/bindings, so multiple
devices could be assigned the same user-friendly-name
- multipath -l an -ll occasionally showed incorrect information
- multipath devices were not being created correctly for luns with a minor
number of greater than 256
- multipath would fail on scsi devices with too large serial numbers.
- multipath devices were not being correctly configured for various IBM
storage devices.
Enhancements included in this update are:
- Improved autoconfiguration for HP and Hitachi storage devices
- device-mapper-multipath is now able to handle DASD devices
- ability to set and change the rr_min_io on a per-device basis
All users are advised to upgrade to these updated packages, which resolve
these issues and add these enhancements.
