Q
It is recommended that a unique node description be specified for each switch.
This name should follow typical naming rules and use the characters a-z, A-Z,
0-9, and underscore. No spaces are allowed in the node description.
Additionally, names should not start with a digit.
For 9024FC switches, the node GUID can be found on a label on the bottom of
the switch. Alternately, the node GUIDs for switches in the fabric can be found
use a command such as:
saquery -t sw -o nodeguid
NOTE:
The above command will report all switch node GUIDs, including those
of internally-managed chassis such as the 9120 model. GUIDs for
internally-managed chassis cannot be specified for use in
-N
,
IBNODES
,
-L
, or
IBNODES_FILE
specified lists.
5.1.8.2
Explicit Switch names
When switches are explicitly specified via the
-N
option or the
IBNODES
environment variable, a space separated list of GUIDs (optionally with name)
may be supplied. For example:
-N '0x00066a00d9000138,i9k138 0x00066a00d9000139,i9k139'
5.1.9
Selection of local Ports (subnets)
Some of the fabric health commands (
fabric_analysis
,
all_analysis
)
permits a specific set of local HCA ports to be used for fabric analysis. The
default is to use the first active port. However, for IB management nodes
connected to more than 1 IB subnet, it is necessary to specify the local HCA and
port such that the desired subnet will be analyzed. When the non-default
behavior is desired, there are multiple ways to specify the local ports to use:
1. Small sets of ports can be easily specified on the command line via the
-p
option discussed below.
2. When multiple commands will be performed against the same small set of ports,
the environment variable
PORTS
can be used to specify a space separated lists
of ports.
3. For groups of ports that will be used often, a file may be created listing the ports.
The defauilt file is
/etc/sysconfig/iba/ports
that should list all local ports
connected to unique subnets. Such a file may then be specified via the
-t
command line option or the
PORTS_FILE
environment variable.
Within the tools the options that are considered in the following order, the first
item listed below that is specified is used for the given command.
