with the -i option or the transport type with the -t option, or both.

 

 

-c

Allows for download of trace or performance firmware onto the adapter. The default firmware on

 

the adapter is performance.

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.
