DESCRIPTION

     The sasinfo utility is a command line  interface  that  col-

     lects  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.


SUB-COMMANDS

     The following subcommands are supported by sasinfo.


     hba


         Lists information for the HBA referenced by  the  speci-

         fied  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  dev-

         ice, 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 speci-

         fied, 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  Manage-

         ment 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 speci-

         fied. This option is used only with the hba-port subcom-

         mand.
