8.196. scsi-target-utils

Updated scsi-target-utils packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The scsi-target-utils packages contain a daemon and tools to setup Small Computer System Interface (SCSI) targets. Currently, software Internet SCSI (iSCSI) and iSCSI Extensions for RDMA (iSER) targets are supported.

Bug Fixes

BZ#910638
Previously, the tgtadm utility did not check for the presence of the libaio library to enable the asynchronous I/O types of backend storage. Consequently, attempts to add a new iSCSI target device with the "tgtadm --bstype aio" command failed with an "invalid request" error message. This update adds libaio as a runtime dependency. Now, using the "--bstype aio" option with the tgtadm utility no longer fails and attempts to add a new logical unit work as expected.
BZ#813636
Prior to this update, when interruptions were occurring in the network, then reconnection of the TCP protocol did not work properly. As a consequence, memory leaks occurred in the tgtd daemon under these circumstances. This bug has been fixed and the TCP reconnection now works correctly in the described scenario.
BZ#865739
Previously, the tgtd daemon did not report its exported targets properly if configured to report them to an Internet Storage Name Service (iSNS) server. Consequently, running the "iscsiadm -m discoverydb -t isns" command failed. This bug has been fixed and tgtd now reports its exported targets correctly in the described scenario.
BZ#922270
Previously, it was not possible to supply command-line parameters to the tgtd daemon. With this update, it is possible to set the TGTD_OPTIONS variable containing the parameters and use it in the /etc/sysconfig/tgtd file.
Users of scsi-target-utils are advised to upgrade to these updated packages, which fix these bugs. All running scsi-target-utils services must be restarted for the update to take effect.
