A command-line tool providing detailed info on connected SCSI devices and hosts on Linux systems.
What is Lsscsi?
lsscsi is a command-line utility for Linux that is used to list information about SCSI devices connected to the system. It provides more detailed information than simply listing block devices. lsscsi is often used by system administrators or storage engineers to troubleshoot issues with SCSI devices or busses.
Some key features and information provided by lsscsi includes:
Listing the SCSI host number, channel, ID, and LUN for connected devices
The type of SCSI device (disk, tape, CD-ROM, etc)
The model name and serial number of devices
The transport protocol used (SCSI, SAS, SATA, USB)
Advanced information like negotiation settings or port speed
lsssi can list devices that may not have any filesystems created on them yet. This allows discovery of hardware that is not yet partitioned. It provides more info than lsblk because it reports directly on the SCSI device layer. Overall, lsscsi is a simple but powerful tool for system admins and engineers to troubleshoot Linux SCSI subsystems.
