RHBA-2013:0457 - Bug Fix Advisory

Topic

Updated fcoe-target-utils packages that fix multiple bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The fcoe-target-utils packages provide a command-line interface for configuring
FCoE LUNs (Fibre Channel over Ethernet Logical Unit Numbers) and backstores.

This update fixes the following bugs:

• Prior to this update, stopping the fcoe-target daemon did not not stop the

target session when rebooting. This update improves the fcoe-target script and
the fcoe-target daemon can now properly shut down the kernel target. (BZ#819698)

• Prior to this update, a delay in the FCoE interface initialization sometimes

resulted in the target configuration not being loaded for that interface. This
update permits target configuration for absent interfaces, allowing target and
interface configuration in any order. (BZ#824227)

• Prior to this update, specifying a nonexistent backing file when creating a

backstore resulted in the unhelpful Python error "ValueError: No such path".
This update reports the error in a more helpful way. (BZ#837730)

• Prior to this update, attempting to remove a storage object in a backstore

resulted in a Python error. This update fixes the problem and storage objects
can now be removed as expected. (BZ#837992)

• Prior to this update, attempting to redirect the output of targetcli resulted

in a Python error. This update allows targetcli to be successfully redirected.
(BZ#838442)

• Due to a regression, creating a backstore resulted in a Python error. This

update allows backstore creation without error. (BZ#846670)

This update also adds the following enhancements:

• Prior to this update, backstore size listing abbreviations did not clearly

specify between power of 10 (for example Gigabyte) and power of 2 (Gibibyte).
This update lists backstore sizes using power-of-2 sizes and labels them as
such. (BZ#828096)

• The caching characteristics of backstores are now exposed via the SCSI Write

Cache Enable (WCE) bit to initiators, instead of being set opaquely via the
"buffered-mode" backstore setting. The default setting for WCE is "on".
(BZ#828681)

All users of fcoe-target-utils are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.
