A–FastFabric Configuration Files
Externally Managed Switch List File
IB0054607-01 A A-15
The GUID will be used to select the switch and on firmware update operations, the
node description will be written to the switch such that other FastFabric tools
(such as
iba_aquery and iba_report) can provide a more easily readable name
for the switch. The node description can also be updated as part of switch basic
configuration.
The hca:port may be used to specify which local port (subnet) to use to access the
switch. If this is omitted, all local ports specified will be checked for the switch and
the first port found to be able to access the switch will be used to access it. See
the FastFabric Command Line Interface Reference Guide for more information
about how to specify and hca:port value.
Files to be included may be specified using an
include directive followed by a file
name. File names specified should generally be absolute path names. If relative
path names are used, they will be searched for within the current directory then
/etc/sysconfig/iba.
Comments may be placed on any line. By using a
# to precede the comment. On
lines with chassis or include directives, the
# must be white-space separated from
any preceding GUID, name or included file name.
QLogic recommends 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 externally-managed 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 using a command such as:
iba_saquery -t sw -o nodeguid
FastFabric is topology aware when updating externally managed switch firmware
or resetting the switches. Switches furthest from the FastFabric node are updated
or reset first and then each switch, working toward the FastFabric node. This way
switches that are rebooted are not in the path between the FastFabric node and
others that are being rebooted.
NOTE:
The preceding command will report all switch node GUIDs, including those
of internally-managed chassis such as the QLogic 12000 or SilverStorm
9120. GUIDs for internally-managed chassis cannot be specified for use in
the ibnodes file.
