Summary of Itutil Command Options
Optional parameters are available so you can filter itutil output. The following table describes
the different command options:
Table 6-1 Itutil Command Options
Descriptionitutil
Displays basic details about all interfaces on a given host. To filter results, specify an interface name
with the -i option or the transport type with the -t option, or both.
Displays Reliable Connection details for specified interface adapters.-c
Allows for download of trace or performance firmware onto the adapter. The default firmware on
the adapter is performance.
-d
Displays help screen.-h
Restricts all subsequent options to a single interface. Use this command alone or in combination
with options -s, -r, -c or -T to filter your itutil results.
-i
Tests link-level connectivity of a remote port specified with a GID.-l
Sends the “count” number of link-loop packets to the GID specified in-l option.-n
Resets statistics for specified interface adapters.-r
Resets the adapter.-R
Displays device and transport specific statistics for specified interface adapters.-s
Displays only adapters with the designated transport type. The only supported transport type is
IB.
-t
Displays list of end-nodes that are reachable from specified interface adapters.-T
Itutil Syntax
The following syntax must be used with itutil command options:
/opt/rdma/bin/itutil -d switch_fw interface_name spigot_id
/opt/rdma/bin/itutil [-srcT] [-i interface_name][-t transport_type]
/opt/rdma/bin/itutil -d trace/notrace interface_name
/opt/rdma/bin/itutil [-n count] -l GID interface_name spigot_id
/opt/rdma/bin/itutil –R interface_name
NOTE: For a 448262-B21 Mezzanine card to work in DDR mode on a 410398-B21 switch blade,
the 410398-B21 switch blade's firmware level must be 1.0.0; if the firmware level is lower than
1.0.0, the 448262-B21 Mezzanine card only works in SDR mode.
Should the level of firmware on the 410398-B21 switch blade be too low to allow the 448262
Mezzanine card to work in DDR mode, the command /opt/rdma/bin/itutil -d
switch_fw interface_name spigot_id is used to upgrade switch firmware on the
410398-B21 HP switch blade. You can perform the upgrade from one of the HP-UX blade systems
connected to the switch.
The (interface_name, spigot_id) pair identifies the Mezzanine card that is connected to
the switch blade.
