1.137.1. RHBA-2011:0093: bug fix update
Updated sq3_utils packages that resolve an issue are now available.
The sg3_utils package contains 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.
These updated sq3_utils packages fix the following bug:
* 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.
In a separate issue, the rescan-scsi-bus.sh shell script did not always detect all LUNs due to a timing issue while checking the device's online status.
With this update, the rescan-scsi-bus.sh script detects all devices even if there is no device with LUN of "0", and the "rescan" command successfully receives the device's online status. ( BZ#529654
All users of sq3_utils are advised to upgrade to these updated packages, which resolve this issue.
