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/.
