mgmthost below for example) and include the hosts file previously created, one
entry per line. Such as:

page 5-3.
4. (All) "Verify Hosts via Ethernet ping" will ping each selected host over the
management network. If all hosts were found, continue to the next step. If
some hosts were not found, abort out of the menu and review the following for
those hosts which were not found:
Is the host powered on and booted
❥
Is the host connected to management network
❥
Is the host management network IP address and network settings consistent
❥
with DNS or /etc/hosts
Is the Management node connected to the management network
❥
Are the Management node IP address and network settings correct
❥
Is the management network itself up (switches, routers, etc)
❥
Is the correct set of hosts listed in the hosts file (the previous step may be
❥
repeated to review and edit the file as needed)
5. (All) "Summary of Fabric Components" will provide a brief summary of the
counts of components in the fabric including how many switch chips, hosts, and
links are in the fabric. It will also indicate if any 1x links were found (which could
indicate a poorly seated or bad cable). Review the results against the expected
configuration of the cluster.
NOTE:
If components are missing or 1x links are found, they should be corrected.
Subsequent steps will aid in locating any 1x links.
6. (Host) If desired "Show Status of Host IB Ports" will allow the state and symbol
error counts of all ports to be manually reviewed.
Instead it is recommended to run:
iba_report -i 10 -o errors -o slowlinks
on the IB Management node. This will check all the ports in the fabric for any
links which have high error rates or are running at a lower speed than expected.
Any such identified links should be diagnosed and corrected.

The link count includes some internal links within the switch boxes. This
means that the count displayed will be greater than the actual number of
cables.
