ETERNUS SF XL-DATA/MV V13 User's Guide

3.1.1 Starting the Daemon

Start the XL-DATA/MV daemon (mftfd) by executing the following command with super-user privileges.

/usr/mftf/lib/mftfd [-t] [-m] -start device name

Option

-t

The option for specifying the output of a completion message.
When a data transfer of the XL-DATA/MV daemon completes successfully or completes with a warning in the UNIX server, the console displays a completion message.
Note that this message refers only to the data transfer on the UNIX server. This message does not appear when the data transfer process is complete on the client.
If the "-t" option is omitted, this message is not output.

-m

The option for specifying the output of an error message.
In the event of an error in the UNIX server, the console displays an error message.
If the "-m" option is omitted, an error in the UNIX server does not send a console message to its client system.
An error message is also output if the error could not be sent to the client system.

-start

This option starts the XL-DATA/MV daemon (mftfd) using the device name specified in the following parameter.

device name

This option specifies the device name of the data transfer volume used by XL-DATA/MV.
Use a device name that allows the viewing of the entire logical unit initialized by the mftfdvini command of the UNIX server.

The following is an example of starting the XL-DATA/MV daemon (mftfd) on a Solaris server with the settings for host-adapter-id=1, target-id=2, and logical unit=3.
The partition that can view the entire logical unit is s2 for Solaris.

/usr/mftf/lib/mftfd -start /dev/rdsk/c1t2d3s2

The following is an example of starting the XL-DATA/MV daemon (mftfd) on an HP-UX server with the settings for host-adapter-id=1, target-id=2, and logical unit=3.

/usr/mftf/lib/mftfd -start /dev/rdsk/c1t2d3

The following is an example of starting the XL-DATA/MV daemon (mftfd) on a Linux server with /dev/raw/raw2 bound to /dev/sd2 by the raw command.

/usr/mftf/lib/mftfd -start /dev/raw/raw2

• Multiple device names cannot be specified.
  To use multiple devices, multiple daemons must be executed.
• For each mftf daemon that starts, a lock file called "lock_(device name)" (e.g., lock_c1t2d3s2 for Solaris) is created in the following directory. If these files are deleted, the XL-DATA/MV daemon (mftfd) may not run properly.

For Solaris servers	:	"/var/opt/FJSVmftf"
For HP-UX servers	:	"var/opt/FHPmftf"
For Linux servers	:	"var/opt/FJSVmftf"

• To commence data transfers, create a user registration file in advance.
• If its system and corresponding logical units are not properly defined as the server system of the XL-DATA/MV during device initialization, the daemon will not start.
• When starting the daemon on a Linux server, the device to be used (/dev/sda, etc.) must be bound to the character device (/dev/raw/raw1, etc.) with the raw command.

The mftfd command has the following additional options:

/usr/mftf/lib/mftfd { -h | -v }

-h : Displays the use of the mftfd command.
-v : Displays the version.

How To Confirm that the Daemon Started

Please confirm that the message of "KJU1001" is outputted to the console displays.

Auto-Start

[For Solaris]

To auto-start the XL-DATA/MV daemon (mftfd) at server startup, make the changes according to the example script created in the following file:

/etc/init.d/mftf

Also, the following files are created during the installation as symbolic links of this file.

/etc/rc2.d/S89mftf
/etc/rc0.d/K48mftf
/etc/rc1.d/K48mftf

[For HP-UX]

To auto-start the XL-DATA/MV daemon (mftfd) at server startup, make the changes according to the example script created in the following file:

/sbin/init.d/mftf

Also, the following files are created during the installation as symbolic links of this file.

/sbin/rc2.d/S734mftf
/sbin/rc1.d/K266mftf

[For Linux]

To automatically start the XL-DATA/MV daemon (mftfd) with the server startup, make the changes according to the example script created in the below file.
When doing so, perform the binding of the device to use and the character device with the raw command before running the following shell script or before starting the daemon in the following shell script.

/etc/rc.d/init.d/mftfd

Also, the following files are created during the installation as symbolic links of this file.

/etc/rc.d/rc0.d/K00mftfd
/etc/rc.d/rc1.d/K00mftfd
/etc/rc.d/rc3.d/S99mftfd
/etc/rc.d/rc5.d/S99mftfd
/etc/rc.d/rc6.d/K00mftfd
