Chapter 14. Storage now correctly interprets multiple word device descriptions

The script, found in the sg3_utils package, previously misinterpreted SCSI device types that were described using more than one word, such as Medium Changer or Optical Device. Consequently, when the script was run on systems that had such device types attached, the script printed multiple misleading error messages. With this update, device types described with multiple words are handled correctly, and the proper device type description is returned to the user without any errors. (BZ#1210438) no longer removes /dev/null

When running the script, due to incorrect syntax in redirecting output to the /dev/null device file while executing the /bin/rm utility, the redirection did not happen but /dev/null was instead interpreted as a file to be removed. As a consequence, running with the --update option removed /dev/null during execution. This bug has been fixed, and /dev/null is no longer removed by (BZ#1245302)

Additional result codes are now recognized by sg_persist

Previously, some SCSI hosts could return result codes which were not recognized by sg_persist, causing it to output an error message claiming the result code is invalid. This update adds additional return codes, such as DID_NEXUS_FAILURE, and the problem no longer occurs. (BZ#886611)

iSCSI boot works correctly in Multi Function mode

Due to incorrect handling of Multi Function mode when dealing with the bnx2x driver, booting iSCSI from Storage Area Network (SAN) did not work correctly for some Host Bus Adapters (HBAs). The underlying source code has been fixed, and iSCSI boot now works correctly in Multi Function mode. (BZ#1276545)
