2.4.1.1 mftfdvini command

Syntax

mftfdvini

device name   [ -i initialization configuration file ]   [ -f ]  { [ -L ] | [ -M ] }

Description

The mftfdvini command initializes the disk as a V11 formatted data transfer volume.
This command is only available to the root.
A confirmation prompt is always displayed when executing this command. Select [Yes] to initialize or [No] to abort the initialization.

After setting the information (e.g., the server system name and client system name) required for initialization to The Initialization Configuration File, execute this command to read the file and initialize the data transfer volume.

---



Executing this command deletes all data on the target disk.
Before executing the command, check the disk for any important data.

---

Option

device name

Specify the full path name for the character device name of the data transfer volume.  (required)

For Solaris	:	Specify the special file name (e.g., /dev/rdsk/c1t1d2s2) with the partition number "s2," which refers to the entire volume.
For HP-UX	:	Specify the character device file name (e.g., /dev/rdsk/c1t1d2).
For Linux	:	Specify the character device file name (e.g. /dev/raw/raw2) whose block device name was bound by the raw command.

-i initialization configuration file

Specify the name of the file under the /etc/mftf/ini directory used for storing the initialization information (e.g., the client system name or server system name) set to the data transfer volume during initialization.
If omitted, the following file is used as The Initialization Configuration File during the initialization.

/etc/mftf/ini/mftfdvini.conf

-f

Specify this to force initialization even when the data transfer volume is in use.
When executing this option during a data transfer, the integrity of the data being transferred cannot be guaranteed.

-L

Specifies 16 partitions per client area on the data transfer volume.
This cannot be specified with -M at the same time. If neither -L nor -M is specified, the number of partitions is 16.

-M

Specifies 10 partitions per client area on the data transfer volume.
This cannot be specified with -L at the same time. If neither -L nor -M is specified, the number of partitions is 16.

---



The number of partitions per client area on the data transfer volume is specified by the -L and -M options for the mftfdvini command.
The value to specify varies depending on the size of the disk to use for the data transfer volume and the multiprocessing level of transfers.
Refer to "Supported Disks and Logical Units" for more information.

---

Return Values

0 is returned when successful.
Otherwise an error message is output and -1 is returned.

Example of Usage

When using the "/etc/mftf/ini/mftfdvini.conf" file for The Initialization Configuration File and initializing the "/dev/rdsk/c1t2d3s2" disk as the XL-DATA/MV data transfer volume:

mftfdvini   /dev/rdsk/c1t2d3s2

When using the "/etc/mftf/ini/mftfdvini_20010630" file for the initialization configuration file and forcing the initialization of the "/dev/rdsk/c1t2d3s2" disk as the XL-DATA/MV data transfer volume:

mftfdvini   /dev/rdsk/c1t2d3s2   -i mftfdvini_20010630   -f

Sample Initialization Configuration File

Data transfers between UNIX servers

When issuing a data transfer request between a UNIX server (node = unix01) and another UNIX server (node = unix02)
(the intermediate disk is "/dev/rdsk/c1t2d3s2" from the unix01 server and "/dev/rdsk/c2t2d3s2" from the unix02 server.)

1. Set the following initialization information to The Initialization Configuration File (mftfdvini.conf) under the "/etc/mftf/ini" directory of unix01

<Client System>
# unix01 -- unix02 declaration
    CLNAME=unix01
    <Server System>
        SVNAME=unix02
        PATH=/dev/rdsk/c2t2d3s2
    </Server System>
</Client System>
# unix02 -- unix01 declaration
<Client System>
    CLNAME=unix02
    <Server System>
        SVNAME=unix01
        PATH=/dev/rdsk/c1t2d3s2
    </Server System>
</Client System>




2. Perform the initialization by executing the mftfdvini command from the unix01 server as shown below:

mftfdvini   /dev/rdsk/c1t2d3s2

Data transfers between a UNIX server and an IA server

When issuing a data transfer request between a UNIX server (node = unix01) and an IA server (computer name = WIN01)
(the intermediate disk is "/dev/rdsk/c1t2d3s2" from the unix01 server and "PHYSICALDRIVE2" from the WIN01 server.)

1. Set the following initialization information to The Initialization Configuration File (mftfdvini.conf) under the "/etc/mftf/ini" directory of unix01.

<Client System>
# unix01 -- WIN01 declaration
    CLNAME=unix01
    <Server System>
        SVNAME=WIN01
        DRIVE=PHYSICALDRIVE2
    </Server System>
</Client System>
<Client System>
# WIN01 -- unix01 declaration
    CLNAME=WIN01
    <Server System>
        SVNAME=unix01
        PATH=/dev/rdsk/c1t2d3s2
    </Server System>
</Client System>





2. Perform the initialization by executing the mftfdvini command from the unix01 server as shown below.

mftfdvini   /dev/rdsk/c1t2d3s2




---



If the physical drive name is uncertain, omit the "DRIVE=" line in The Initialization Configuration File (mftfdvini.conf), execute the mftfdvini command, then execute the mftfdvadd command after checking the physical drive name displayed on the Disk Utility.

---

Data transfers between a UNIX server and a Linux server

When issuing a data transfer request between a UNIX server (node = unix01) and a Linux server (node = Linux02):
(When "/dev/rdsk/c1t2d3s2" from the standpoint of the unix01 server and "/dev/sda2" from the standpoint of the linux02 server is bound to "/dev/raw/raw2" by the raw command for the intermediate disk to be used)

1. Set the following initialization information to The Initialization Configuration File (mftfdvini.conf) under the "/etc/mftf/ini" directory of unix01 server:

<Client System>
# unix01 -- linux02 declaration
    CLNAME=unix01
    <Server System>
        SVNAME=linux02
        PATH=/dev/raw/raw2
    </Server System>
</Client System>
# linux02 -- unix01 declaration
<Client System>
    CLNAME=linux02
    <Server System>
        SVNAME=unix01
        PATH=/dev/rdsk/c1t2d3s2
    </Server System>
</Client System>





2. Execute the mftfdvini command from the unix01 server as shown below:

mftfdvini /dev/rdsk/c1t2d3s2
