sdparm 0.91

sdparm is a command line utility designed to get and set SCSI disk parameters (cf hdparm for ATA disks). More generally it gets and sets mode page information on SCSI devices or devices that use a SCSI command set (e.g. CD/DVD drives (any transport) and SCSI tape drives). It also can list device identification descriptors from VPD pages.

This utility overlaps in functionality somewhat with blktool by Jeff Garzik.

sdparm 0.90 was the original version released. ChangeLog for sdparm-0.91 [20050506]
- if lk 2.4 detected, map primary SCSI node to sg node for ease of use
- add support for '--inquiry' (VPD pages, defaults to device identification)
- decode format and rigid disk mode pages (sbc2) [both pages are obsolete but common]
