Updated device-mapper-multipath packages that fix one bug are now available for Red Hat Enterprise Linux 6 Extended Update Support.
The device-mapper-multipath packages provide tools to manage multipath devices using the device-mapper multipath kernel module.
If the multipath device was deleted while a path was being checked, multipathd did not abort the path check and terminated unexpectedly when trying to access the multipath device information. The multipathd daemon now aborts any path checks when the multipath device is removed and the problem no longer occurs.
All users of device-mapper-multipath are advised to upgrade to these updated packages, which fix this bug.
