Useful to quickly check cabling and hardware setup. Zeroconf tool that scans SAS devices and resolves associated enclosures. `- 1 x end_device - enclosure io1-jbod1-1 QCT sas_devices | `- 1 x end_device - enclosure io1-jbod1-0 QCT Use -v, -vv or -vvv and -addr to display more details. By default, sas_discover tries to fold common devices (like disks).

This command also supports SES-2 nicknames as seen in the example below ( io1-sassw1 is the nickname of a SAS switch and io1-jbod1-0 is the nickname of a JBOD SIM). Sas_counters reports SAS/SES/SD I/O and phy error counters and provides SAS topology information in an output suitable for Carbon/Graphite. While sasutils gets most of the system data from sysfs (/sys), sg_ses (available in sg3_utils or sg3-utils)Īnd smp_discover (available in smp_utils or smp-utils) are required for some SES features to work. sasutils command-line toolsĪlso, two “zeroconf” udev scripts for use in udev rules that create friendly device aliases using SES-2 subenclosure nicknames.
