Display List of Spigots Reachable from the Interface Adapter(s)

nwmgr -S rdma [--class_instance

interface ...] -q topo

Displays the list of spigots reachable from the interface adapter(s). The list is displayed for each

local spigot. The list contains the network address and the node description as advertised in the

fabric for that spigot.

Reset the Adapter

nwmgr -r -S rdma -c interface [-f

]

While the reset is in progress, the data trafﬁc through the interface is interrupted. The command

automatically performs a Critical Resource Analysis to see if the interface is data-critical, i.e., any

other resource depends for its functionality on the availability of the interface. If so, the reset is not

performed. The reset can be forced, if the adapter is data-critical, by using the

--force option. It

is possible for an adapter to be system-critical, i.e., the health of the system depends on the availa-

bility of the adapter. In that case, the reset will not be performed even if the

--force

option is

speciﬁed.

Download trace or notrace version of Firmware onto Adapter

nwmgr --do -S rdma -c interface -A fw_type={trace|no_trace}

This command downloads the trace or notrace (performance) version of the ﬁrmware onto the

adapter. You must reset (with -r) the adapter for the version of the ﬁrmware to be activated.

Select the ﬁrmware type notrace (performance) unless directed by HP support.

Diagnose Link Connectivity

nwmgr --diag linkloop -S rdma -c interface -q dgid= destination_GID

, spigot=spigot_ID

[

--it number_of_packets]

This command performs a linkloop-like packet send to check connectivity to an adapter. The

--it

option speciﬁes how many test frames to send; the default is 3.

Perform Critical Resource Analysis on the Adapter

nwmgr --cra -S rdma -c interface

RETURN VALUES

0 The command returns 0 on success.
