Details

Updated device-mapper-multipath packages that resolve an issue are now
available.

The device-mapper multipath packages provide tools to manage multipath
devices by issuing instructions to the device-mapper multipath kernel
module, and by managing the creation and removal of partitions for
device-mapper devices.

These updated packages provide the following enhancement:

* with updated firmware from Sun, and with Automatic Volume Transfer (AVT)
enabled, the Sun StorageTek 6540 storage arrays can be made to work with
multipath but device-mapper-multipath did not auto-configure them. With
this update the necessary information was added to multipath.conf.defaults
and hwtable and device-mapper-multipath now auto-configures Sun StorageTek
6540 storage arrays. (BZ#523392)

Note: this new functionality will not be available unless the kernel
update, RHSA-2009:1455, has also been installed. For details regarding this
see http://rhn.redhat.com/errata/RHSA-2009-1455.html.

In addition, these updated packages fix the following bug:

* the kpartx utility creates device maps from partition tables.
Device-mapper devices with minor numbers greater than 255 caused kpartx to
use the UUID from the wrong device when trying to create partitions. If the
device had pre-existing partitions, kpartx would fail to create the new
partitions. With this update, kpartx is now able to handle device-mapper
devices with minor numbers greater than 255. (BZ#528132)

Multi-path users, especially those using Sun StorageTek 6540 storage
arrays, should install these updated packages, which add this enhancement
and fix this bug.
