Faulty controller or peripheral hardware (such as cables, disk drives, etc.) will not cause this utility to hang. It will exit with the appropriate return value. If an operation fails, clear the fault condition by whatever means necessary and retry the operation. DISABLEIR The DISABLEIR command turns off IR functionality on a SAS controller, by setting the MPI_IOUNITPAGE1_DISABLE_IR bit in the IO Unit 1 MPT Configuration Page. - Page 49 The sasflash.efi utility and firmware images are included on the IPF Offline Diagnostics and Utilities CD, version 0803 and later. To update the adapter firmware offline, follow the procedures provided with the sasflash utility. CAUTION: If you have updated the adapter firmware using sasflash, booting a disk with an older version of SerialSCSI-00 (including Ignite-UX) might download an older version of the firmware and EFI driver to all HBAs controlled by SerialSCSI-00 in the system.
