RHBA-2012:1599 - Bug Fix Advisory

Topic

Updated device-mapper-multipath packages that fix one bug are now available for
Red Hat Enterprise Linux 5.

Description

The device-mapper-multipath packages provide tools to manage multipath devices
using the device-mapper multipath kernel module.

This update fixes the following bug:

• If the initrd RAM disk was not rebuilt when a new storage device was added to

the system, the new device could be assigned a user_friendly_names value that
collided with a value already assigned to another device. Consequently, the
original device then stopped working correctly. Now, the multipathd daemon
accepts the "-B" option, which makes the user_friendly_names bindings file
read-only. When initrd calls multipath with the "-B" option, devices without a
binding to a user_friendly_names use their World Wide Identifier (WWID) instead,
thus fixing this bug. (BZ#858010)

All users of device-mapper-multipath are advised to upgrade to these updated
packages, which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
