Synopsis
device-mapper-multipath enhancement update
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 packages provide tools to manage multipath
devices through the device-mapper multipath kernel module.
Enhancements included in this update are:
- Added multipath support on CCISS devices.
- Added implicit support for active-active failover (ALUA) functionality,
which will be available in upcoming EMC CLARiiON arrays.
- Added support for the mpath_prio_tpc priority callout. This allows
retrieval of priority paths from storage devices such as SAN, STK
OpenStorage D20, and Flexline 280.
- Added a "bindings_file" config file option. This allows the user to
configure where multipath will look for the user_friendly_names bindings file.
This update also fixes the following bugs:
- The multipathd init script contained several error code return commands;
some of these errors prevented the status command from being invoked. This
issue is now corrected by this update, and the status command now runs
correctly.
- When trying to identify paths and priority groups, devices that use the
dasdview command to do so would fail. This was caused by an upstream change
to dasd that replaced the "-f [device_name]" option with "[device_name]".
This change was not compatible with older versions of s390-tools (which
provides the dasdview utility). To fix this, the "-f [device_name]" option
is now enabled by default for all devices that use the dasdview command.
- Running multipath on a pSeries server connecting to a SAN environment
could result in an error. This was caused by an insufficient macro
definition of WWID_SIZE in multipath-tools-0.4.5.64/libmultipath/structs.h.
This update increases WWID_SIZE to 128, which fixes this problem.
- Multipath did not work with devices that had a UUID of more than 64
characters.
- When reading /etc/multipath.conf, multipath incorrectly processed
non-ascii characters. Now, multipath treats all non-ascii characters as
whitespace, except for those inside quoted strings.
All multipath users are advised to upgrade to these updated packages, which
resolve these issues and add these enhancements.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
