sasinfo [-?]
The sasinfo utility is a command line interface that collects administrative information on Serial Attached SCSI-2 (SAS-2) host bus adapter (HBA) that supports the Storage Management HBA API (SM-HBA). The utility reports attributes of HBA ports and of expander devices and SCSI target devices that might be connected to those HBA ports.
sasinfo is implemented as a set of subcommands, described below.
The following subcommands are supported by sasinfo.
hba
Lists information for the HBA referenced by the specified HBA_name. If HBA_name is not specified, all HBAs on the host will be listed.
hba-port
Lists information for the HBA port referenced by the specified HBA_port_Name. If HBA_port_Name is not specified, all HBA ports on the host will be listed. Note that HBA ports can be dynamically configured/unconfigured so that the number of HBA ports on an HBA can change as connections to target devices are established. With no connections to a storage device, no HBA port is configured.
expander
Lists hierarchical view of the expander referenced by the specified Expander_SAS_Addr. If no argument is specified, all expanders that are visible across all HBA ports on the host will be listed.
target-port
Lists information for those target ports referenced by Target_port_SAS_Addr address. If no argument is specified, all target ports that are visible on the host will be listed.
logical-unit | lu
Lists the logical unit referenced by the specified device_path. If device_path is not specified, all SAS logical units will be listed, including the SAS Management Protocol (SMP) target port.
The following options are supported.
-?, --help
Displays usage information
-a, --hba HBA_Name
Retrieve HBA port information from the HBA_Name of an HBA on the host. The -a option can only be used with the hba-port subcommand.
-l, --phy-linkstat
Lists the link error statistics information for the phys on the HBA port referenced by the specified HBA_port_Name or all HBA ports if no HBA port is specified. This option is used only with the hba-port subcommand.
-p HBA_port_SAS_Addr, --port HBA_port_SAS_Addr
Retrieve remote port information from the HBA_port_SAS_Addr of the local HBA port on the host. The -p option can be used only with the expander subcommand.
-s, --scsi
Lists SCSI attributes for target ports that are requested for display. This option is only used for the target-port subcommand.
-v, --verbose
Display details on hardware information, such as SAS address, topology device, and so forth, based on which subcommand is invoked.
-V, --version
Displays the version information.
-y, --phy
Lists the phy information on the HBA port specified by HBA_port_Name or all HBA ports if no HBA port is specified. This option is used only with the hba-port subcommand.
