DESCRIPTION

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.

SUBCOMMANDS

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.

OPTIONS

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.
