RHBA-2010:0721 - Bug Fix Advisory

Topic

An updated iscsi-initiator-utils package that fixes a bug is now available.

Description

The iscsi-initiator-utils package provides the server daemon for the iSCSI
protocol, as well as the utility programs used to manage it. iSCSI is a protocol
for distributed disk access using SCSI commands sent over Internet Protocol
networks.

This updated iscsi-initiator-utils package fixes the following bug:

• Previously, iscsiadm did not contain a discovery mode with an update option.

This prevented vdsm to discover targets with CHAP (Challenge-Handshake
Authentication Protocol) authentication. This update adds a iscsiadm discoverydb
mode ('iscsiadm -m discoverydb') which fixes this issue and can be used to
create, store and edit discovery records. (BZ#604649)

• Previously, iscsid shared the 'semarg' structure between multiple devices and

thus caused a deadlock to occur when logging was initiated. With this update,
each process is assigned its own structure and deadlocks no longer occurs during
the logging process. (BZ#632094)

All users of iscsi-initiator-utils are advised to upgrade to this updated
package, which resolves this issue.
