RHBA-2013:1700 - Bug Fix Advisory

Topic

Updated iscsi-initiator-utils packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The iscsi-initiator-utils packages provide the server daemon for the iSCSI
protocol, as well as utilities used to manage the daemon. iSCSI (Internet Small
Computer System Interface) is a protocol for distributed disk access using SCSI
commands sent over Internet Protocol networks.

The iscsi-initiator-utils packages have been upgraded to upstream version
6.2.0.873, which provides a number of bug fixes and enhancements over the
previous version. (BZ#916007)

This update also fixes the following bugs:

• Previously, database errors could occur if multiple node records in different

formats were created for the same iSCSI target portal. Consequently, depending
on the file system dependent return order of the readdir syscall, an error
occasionally occurred causing an update operation to fail. To fix this bug,
multiple node records in different formats have been prevented from existing
simultaneously and detected at record creation time. Duplicate node entries no
longer exist in the iSCSI database, and updates to records do not result in
database errors. (BZ#884427)

• Prior to this update, a single unreachable target could previously block

rescans of others. Consequently, the iscsiadm utility could halt in the D state
and the rest of the targets could remain unscanned. To fix this bug, iscsiadm
has been made terminable and all the targets have been updated. Now, functioning
sessions will be rescanned properly without long delays. (BZ#983553)

• When VDMS (Virtual Desktop Server Manager) attempted to add a new record to

the iSCSI database, it failed with the following error:

iscsiadm: Error while adding record: no available memory.

Consequently, due to this error, the host became non-operational when connecting
to storage. An upstream patch has been applied and the /var/lib/iscsi file is
now successfully attached. (BZ#1001705)

In addition, this update adds the following enhancements:

• For the bnx2i hardware and potentially other offloading solutions

(complementary network technologies for delivering data originally targeted for
cellular networks), the iscsistart tool for passing along the VLAN tag from iBFT
(iSCSI Boot Firmware Table) to iface_rec (iscsi iface record name) has been
implemented to this package. (BZ#831003)

• With this update, support for managing Flash nodes from the open-iscsi utility

has been added to this package. (BZ#917600)

Users of iscsi-initiator-utils are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.

Solution

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