说明
sginfo accesses mode page information for SCSI and ATAPI devices. It can display and modify SCSI mode pages which control various device behaviors such as caching, error recovery, and power management. Each SCSI device maintains four sets of values for mode pages: current (active values), default (manufacturer's settings), saved (values retained across power cycles), and changeable (mask of modifiable fields). The primary use case is reading and modifying device configuration through mode pages. Mode pages can be displayed in raw hexadecimal or decoded format, and modified values can be written back to the device.
