sdparm is a command line utility designed to get and set SCSI device parameters (cf hdparm for ATA disks). The parameters are held in mode pages. Apart from SCSI devices (e.g. disks, tapes and enclosures) sdparm can be used on any device that uses a SCSI command set. Virtually all CD/DVD drives use the SCSI MMC set irrespective of the transport. sdparm also can decode VPD pages including the device identification page. Commands to start and stop the media; load and unload removable media and some other housekeeping functions are supported. sdparm supports both the lk 2.4 and 2.6 series. This version fixes a problem that appeared in version 0.98: A Request Sense command was added to clear down any pending Unit Attention conditions but libata doesn't support Request Sense. This version expands the exit status values which are the same as those found in the recently released sg3_utils version 1.21 .
