Displaying the List of End-Nodes Description: This parameter displays the list of end-nodes
that are reachable for all specified adapters (i.e. the Topology of the cluster). If an adapter is not
specified using the -i parameter, the -T command displays the topology information for every
HP Fabric interface configured on the host.
Syntax: itutil -T [-i interface name|-t transport type]
Example: itutil -T
Testing Link-level Connectivity This option is similar to the linkloop command for LAN
interfaces. If the -n option is not specified, the default value for “count” is 1. Setting the count
to 0 will result in itutil sending packets indefinitely until an interrupt signal is received.
Description: This parameter tests link-level connectivity with the remote port specified with the
GID (Global Identifier) for transport type IB.
NOTE: The GID of an adapter port is displayed using either the itutil or itutil -i
commands as the “Primary Network Address”.
Syntax: itutil [-n count]-l GID interface_name spigot_id
Syntax Example: itutil -l fe80::2:c901:8a0:8a11 ib0 1
Output Example:
Testing connectivity to Network Address 0x<fe80::2:c901:8a0:8a11>
from IA "ib0", spigot id "1"
Linkloop Succeeded.
Testing Link-level Connectivity with a Specified Number of Packets This option is similar to the
linkloop command for LAN interfaces. If the -n option is not specified, the default value for
“count” is 1. Setting the count to 0 will result in itutil sending packets indefinitely until an
interrupt signal is received.
Description: The -n parameter sends a specified “count” number of linkloop packets to the GID
specified in the -l parameter.
Syntax: itutil [-n count]-lGID interface_name spigot_id
Syntax Example: itutil -n 5 -l fe80::2:c901:8a0:8a11 ib0 1
Output Example:
Testing connectivity to Network Address 0x<fe80::2:c901:8a0:8a11>
from IA "ib0", spigot id "1"
Linkloop Succeeded.
