RHBA-2016:0138 - Bug Fix Advisory

Topic

Updated sg3_utils packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The sg3_utils packages provide command-line utilities for devices that use the
Small Computer System Interface (SCSI) command sets.

This update fixes the following bugs:

• The rescan-scsi-bus.sh tool misinterpreted SCSI device types that were

described using more than one word, for example, "Medium Changer" or "Optical
Device". Consequently, when the script was run on systems that had such device
types attached, the script printed multiple misleading error messages. With this
update, device types described with multiple words are handled correctly, and
the proper device type description is returned to the user without any errors.
(BZ#1291579)

• When running the rescan-scsi-bus.sh script, due to incorrect syntax in

redirecting output to the /dev/null device file while executing the /bin/rm
utility, the redirection did not happen but /dev/null was instead interpreted as
a file to be removed. As a consequence, running rescan-scsi-bus.sh with the
"--update" option removed /dev/null during execution. This bug has been fixed,
and /dev/null is no longer removed by rescan-scsi-bus.sh. (BZ#1300338)

Users of sg3_utils are advised to upgrade to these updated packages, which fix
these bugs.
