NAME sginfo - access mode page information for a SCSI (or ATAPI) device SYNOPSIS sginfo [OPTIONS] [DEVICE] [REPLACEMENT_PARAMETERS] DESCRIPTION sginfo is a port of the Linux scsiinfo program by Eric Youngdale. It uses SCSI generic (sg) devices; however in some cases the high level device name (i.e. sd, sr, st, osst, or hd) can also be used. The pri- mary role of this program is to access mode page information. If per- mitted, mode page information can be altered. In addition information from the INQUIRY and READ DEFECTS commands are also available. Those interested in SCSI mode pages may find the sdparm utility easier use, especially for changing parameters. Also the author considers this utility legacy so the mode pages are not being
