Both of these options assume that your e-mail address is valid and that your
system is configured such that the e-mail can be sent. SysBack is sending the
e-mail via the AIX mail command. It is the customer’s responsibility to properly
configure their mail options. This might be useful when you would like and e-mail
sent to a particular Computer Operator each time a tape needs to be changed, or
simply for record keeping purposes.
Email Address For EOT on Write Operations.
Specify this option to force SysBack to execute the specified
script/program when the end of tape is reached (triggered by the sbwrite
and sbfwd commands). You must specify the fully qualified path to the
script/program and it must be present on the same physical machine as
where the tape drive / library is located. This option only applies to
backup operations.
Email Address For EOT on Read Operations.
Specify this option to force SysBack to execute the specified
script/program when the end of tape is reached (triggered by the sbread
command). You must specify the fully qualified path to the script /
program and assumes that it is present on the same physical machine as
where the tape drive or library is located. This option only applies to
restore operations.
Both of these options would be used in a situation whereby you did not have an
autoloading library, but instead a robotic library that requires special commands to
move the robot arm for picking up and moving tapes. You could write your own
script or program to manipulate the tapes when the end of volume is reached.
Three command line arguments will be passed to your program. You may take
advantage of them if you choose. They are:
v
$1 This argument represents the device that requires the tape change. The
value will be in the form of /dev/rmt0.
v
$2 This argument represents the hostname of the client whose data is being
backed up. It should be in the form of what is returned by running the“
hostname” command on that client
v
$3 This argument represents the value of the next tape to load. For
example, at the end of tape 1, this value would be “2” since the 2nd
volume that should loaded.
As an example configuration, let’s assume that when he backup’s “sbwrite”
command hits the end of tape of tape 1, and needs to span to tape 2, (assuming
that this is only a 2 tape backup), you would specify the program name in SMIT
like so:
PROGRAM_WRITE change_tape
Therefore, when the end of the first tape was reached on host sysback1, SysBack
would execute this command:
change_tape /dev/rmt0 sysback1 2
Where change_tape might be a shell script like this:
