Bug Fix Advisory scsi-target-utils bug fix and enhancement update

Advisory: RHBA-2011:1049-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2011-07-21
Last updated on: 2011-07-21
Affected Products: RHEL Cluster-Storage (v. 5 server)

Details

An updated scsi-target-utils package that fixes multiple bugs and adds one
enhancement is now available for Red Hat Enterprise Linux 5.

The SCSI target package contains the daemon and tools to setup iSCSI and iSER
targets.

This update fixes the following bugs:

* Prior to this update, there was a bug in the "tgt-setup-lun" command that
caused a target to be deleted if an invalid Logical Unit Number (LUN) was added.
The problem has been resolved in this update so that "tgt-setup-lun" now works
as expected and the target is not deleted. (BZ#695867)

* Prior to this update, there was a bug in the iscsid and tgtd daemons that
caused the system log to be filled with the "iscsid: semop down failed" and
"tgtd: semop up failed" error messages while starting and stopping the
respective services in a particular order. The bug has been fixed in this update
so that no error messages from iscsid and tgtd are now written in the system
log. (BZ#676804)

* Prior to this update, there was a problem with using very large (more than 2TB
in size) hard disks with iSCSI. As a result, the iSCSI initiator failed with
"very big device. try to use READ CAPACITY(16)" and "unsupported sector size"
error messages. This bug has been fixed in this update so that using such hard
disks with iSCSI now works as expected. (BZ#674394)

* Prior to this update, the iSCSI initiator on Windows Server 2003 was not able
to use Logical Unit Numbers (LUNs) provided by the tgtd daemon on Linux. It did
not recognize simultaneous Linux SCSI Target Framework (STGT) LUNs provided by
the same STGT target. This bug has been fixed in this update so that the iSCSI
initiator is now able to use the LUNs as expected. (BZ#560534)

As well, this update adds the following enhancement:

* This update adds support for a read-only target by setting the "--params
readonly=1" option with the "tgtadm" command, or by setting the "readonly 1" and
"allow-in-use yes" options in the /etc/tgt/targets.conf file. (BZ#695870)

All users requiring scsi-target-utils should upgrade to this updated package,
which fixes these bugs and adds this enhancement.
