RHEA-2018:1402 - Product Enhancement Advisory

Topic

An updated python-rtslib package that fixes two bugs and adds one enhancement is now available for Red Hat Enterprise Linux 7.

Description

The python-rtslib package provides a Python library to configure the kernel target subsystem, using the configfs file system.

This update fixes the following bugs:

• Previously, the targetcli utility removed storage objects under certain conditions. This happened when the volume hosting the storage objects was down and the user restored target configuration with the command "targetcli restoreconfig". With this update, configuration is now saved at a block granularity, and, as a result, the described problem no longer occurs. (BZ#1566103)
• Previously, the "targetcli saveconfig" command did not save the max_data_area_mb control string. As a consequence, the property was lost when restarting the target service or rebooting the node. With this update, the property is saved and restored correctly. (BZ#1566106)

In addition, this update adds the following enhancement:

• This update enables the Asymmetric Logical Unit Access (ALUA) feature for the pscsi and tcmu back ends if the kernel supports it. The "targetcli list" command is now able to list ALUA groups. (BZ#1566099)

Users of python-rtslib are advised to upgrade to this updated package, which fixes these bugs and adds this enhancement.

Solution

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