Updated sg3_utils packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The sg3_utils packages contain a collection of tools for SCSI devices that use the Linux SCSI generic (sg) interface. It includes utilities for database copying based on "dd" syntax and semantics (the "sg_dd", "sgp_dd" and "sgm_dd" commands), INQUIRY data checking and associated pages ("sg_inq"), mode and log page checking ("sg_modes" and "sg_logs"), disk spinning ("sg_start") and self-tests ("sg_senddiag"), as well as other utilities. It also contains the rescan-scsi-bus.sh script.
When scanning for iSCSI devices, if no device existed with a Logical Unit Number (LUN) of "0", then the rescan-scsi-bus.sh shell script failed to detect any other devices as well. With this update, the rescan-scsi-bus.sh script detects all iSCSI devices even if there is no device with LUN of "0".
All users of sg3_utils are advised to upgrade to these updated packages, which fix this bug.
