|
# This is the configuration file for table driven failover support.
|
|
# The entries within this file consist of a single line per
|
|
# failover grouping. These lines describe up to four paths to
|
|
# each device. Obviously, these paths should reference the
|
|
# same device! Some sanity checking is performed, but the
|
|
# software is not foolproof in this area. (If it was foolproof,
|
|
# the configuration file would be unnecessary!) It is recommended
|
|
# that all paths to a device be listed.
|
|
#
|
|
# The format of each line consists of a group name followed by
|
|
# up to four device names from the "/dev/scsi" directory. If
|
|
# it's not in "/dev/scsi", it cannot be configured. But, this
|
|
# implementation assumes that if a device is not present, its
|
|
# path has failed. Consequently, no error messages will be
|
|
# generated for missing paths. This means that you may have a
|
|
# a failover group that consists of a single primary path with
|
|
# no alternates.
|
|
#
|
|
# Additionally, there is a configuration directive available that
|
|
# will cause the program to emit debug information. Placing
|
|
# "#verbose" at the start of a line, without the quotes, will
|
|
# enable the debug output. The debug output is displayed for
|
|
# all subsequent configuration directives. Once enabled, the
|
|
# debug output cannot be disabled.
|
|
#
|
|
# Lines that begin with a "#" are considered comment lines.
|
|
# A "#" anywhere within a line signals the beginning of a comment.
|
|
# White space must separate the last parameter of a line and the #.
|
|
# Blank lines are also considered a comment.
|
|
#
|
|
# --> Lines that begin with 'sc' will be skipped as it's likely a
|
|
# --> configuration error.
|
|
#
|
|
# Sample configuration. (Remember to omit the "#" the start of
|
|
# the line.)

|
# One word of caution. The switch to an alternate path is
|
|
# choreographed by XLV. XLV is a requirement for failover to
|
|
# function.
|
|
#
|
|
# Notes:
|
|
#
|
|
# It is not possible to change the primary device of a group after
|
|
# the initial configuration by reordering the entries on the line
|
|
# and running /etc/init.d/failover start. To change the primary,
|
|
# scsifo may be used to switch to the next available path.
|
|
#
|
|
# It is not possible to remove the primary of a group by deleting
|
|
# the entry from the group and running /etc/init.d/failover start.
|
|
# A reboot is necessary.
|
|
#
|
|
# To remove the "DOWN" displayed by hinv for the failed path,
|
|
# fix the path and reprobe the bus using scsiha -p #.
