HP-UX Host Administration and Management
This section describes the itutil and nettl tools, which are used to manage the HP-UX Host in the HP
Fabric Clustering System. In addition, there is a separate section describing the administration and
management of IPoIB. For information on managing the switch, refer to “Switch Administration and
Management” on page 59.

Using Itutil
Itutil is a tool used to manage the RDMA infrastructure which exposes the industry standard IT-API and
InfiniBand on HP-UX. itutil provides detailed information about HP Fabric Clustering System-configured
hosts, such as interface status and statistics and system connectivity. Commands are grouped into two major
categories: Administrative and Managing. Each command option is described in a task-based format,
providing commands and available options, syntax, and syntax and output examples. itutil is located in
/opt/rdma/bin directory.
Summary of Itutil Command Options
Optional parameters are available so you can filter itutil output. The following table describes the different
command options:
Table 5-1 Itutil Command Options
itutil Description
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.
-c Displays Reliable Connection details for specified interface adapters.
-d Allows for download of trace or performance firmware onto the adapter. The default firmware on
the adapter is performance.
-h Displays help screen.
-i 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.
-l Tests link-level connectivity of a remote port specified with a GID.
-n Sends the “count” number of link-loop packets to the GID specified in-l option.
-r Resets statistics for specified interface adapters.
-R Resets the adapter.
-s Displays device and transport specific statistics for specified interface adapters.
-t 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.
