| * CONTENTS |
| * Some SCSI commands are executed in many contexts and hence began |
| * to appear in several sg3_utils utilities. This files centralizes |
| * some of the low level command execution code. In most cases the |
| * interpretation of the command response is left to the each |
| * utility. |
| * One example is the SCSI INQUIRY command which is often required |
| * to identify and categorize (e.g. disk, tape or enclosure device) |
| * a SCSI target device. |
| * CHANGELOG |
| * v1.00 (20041018) |
| * fetch low level command execution code from other utilities |
| * v1.01 (20041026) |
| * fix "ll" read capacity calls, add sg_ll_report_luns |
