Q
1. Small sets of chassis can .be easily specified on the command line via the
-H
option discussed below
2. When multiple commands will be performed against the same small set of
chassis, the environment variable
CHASSIS
can be used to specify a space
separated lists of chassis.
3. For groups of chassis which will be used often, a file may be created listing the
chassis. The defauilt file is
/etc/sysconfig/iba/chassis
which should
list all chassis in the cluster. Such a file may then be specified via the
-F
command line option or the
CHASSIS_FILE
environment variable.
Within the tools the options are considered in the following order, the first item
listed below that is specified is used for the given command.
1.
-H
option
2.
CHASSIS
environment variable
3.
-F
option
4.
CHASSIS_FILE
environment variable
5.
/etc/sysconfig/iba/chassis
file
For example if the
-H
option is used and the
CHASSIS_FILE
environment
variable is also exported, the command will operate only on chassis specified
via the
-H
option.
5.1.7.1
Chassis List Files
The
-F
option or the
CHASSIS_FILE
environment variable may be used to
provide the name of a file containing the list of SilverStorm IB chassis to operate
on. The default is
/etc/sysconfig/iba/chassis
. In some fabrics it may
be useful to create multiple files in
/etc/sysconfig/iba
representing
different subsets of the fabric the user may operate from. For example:
/etc/sysconfig/iba/chassis-core
: list of core switching chassis
/etc/sysconfig/iba/chassis-edge
: list of edge switching chassis
/etc/sysconfig/iba/esm_chassis
: list of chassis running an SM
/etc/sysconfig/iba/chassis
: list of all chassis
If a relative path is specified for the
-F
option or
CHASSIS_FILE
, the current
directory will be checked first, followed by
/etc/sysconfig/iba/
.
