Setup Network Environment

This function sets up an the environment for the storage system to communicate with an external network.

Configuration is required for each MNT, RMT and FST port.

• MNT port

  The MNT port is used for general communication between the storage system and the external hosts.

  For the ETERNUS DX60 S5/DX100 S5/DX200 S5 and the ETERNUS AF150 S3/AF250 S3, this port is also used for maintenance of the storage system.

• RMT port

  The RMT port is used when the line must be separated from the MNT port.

  This port must be configured for the ETERNUS DX500 S5/DX600 S5/DX900 S5, the ETERNUS DX8100 S4/DX8900 S4, and the ETERNUS AF650 S3.

• FST port

  The FST port is used for maintenance of the storage system.

  This port must be configured for the ETERNUS DX500 S5/DX600 S5/DX900 S5, the ETERNUS DX8100 S4/DX8900 S4, and the ETERNUS AF650 S3.

MNT ports or RMT ports support "IPv4" and "IPv6". Click the [IPv4 Settings] Tab or [IPv6 Settings] Tab to set the network environment. FST ports only support "IPv4". Specify "Interface" in the [IPv4 Settings] Tab.

[IPv4 Settings] Tab

In this screen, configure the network environment for IPv4.

Up to 16 addresses are displayed.

Function Button

[Add Allowable IP Address] Screen

In this screen, input the information of the remote storage systems for which network access will be allowed.

Allowable IP Address Settings

IPv6 Address Notation

Since the IPv6 address is 128-bit and extremely long, this address is displayed using "xxxx", which describes 16-bit in hexadecimals as being one block that is separated by colons (":").

xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

   • Use 0 - ffff (FFFF) (hexadecimal, alphanumeric characters) for inputting an IPv6 address

   • The current setting is displayed with 0 - ffff (hexadecimal, "a" - "f" are lowercase letters)

   • Up to 128-bit

   • The first 64-bit (prefix) of the link local address is fixed to "fe80::"

The following three abbreviation methods are available for IPv6 addresses:

(1) Omission of the first "0" of a block that follows consecutive zeros.

[Example] 2001:1000:0120:0000:0000:0123:0000:0000

      ↓

      2001:1000:120:0000:0000:123:0000:0000

(2) Replacement of "0000" blocks with "0".

[Example] 2001:1000:120:0000:0000:123:0000:0000

      ↓

      2001:1000:120:0:0:123:0:0

(3) Replacement of a block with consecutive zeros by "::" is performed only once.

[Example] 2001:1000:120:0:0:123:0:0

      ↓

      2001:1000:120::123:0:0 is OK

      2001:1000:120::123:: is not allowed (Replacement of a block with consecutive zeros by "::" is allowed only once.)

Available IPv6 Address

Supplementary Information

• When accessing of the storage system from a different subnetwork is not allowed

  Specify "IP Address" and "Subnet Mask" of the storage system.

  Only accessing from the same subnetwork is allowed.

• When accessing of the storage system from a different subnetwork is allowed

  Specify "Gateway" and "Allowable IP Address ("IP Address" (or "Network Address") and "Subnet Mask")".

  [Example] Allowable IP Address (for IPv4)

  • When accessing of the storage system from a specific client outside the subnetwork is allowed, specify "IP Address" and "Subnet Mask".

       IP Address: 10.20.30.40

       Subnet Mask: 255.255.255.255

  • When accessing of the storage system from a specific subnetwork outside the subnetwork is allowed, specify "Network Address" and "Subnet Mask".

       IP Address: 10.20.30.0

       Subnet Mask: 255.255.255.0

  For IPv6, "IP Address" corresponds to "Connect IP Address", and "Subnet Mask" corresponds to "Length of Subnet Prefix".

In this screen, configure the network environment for each port.

When Using IPv4

1. Select which port that the network environment is to be set for, and click [Setup Network Environment] in [Action].

2. Specify the parameters.

3. To allow access from a different subnetwork to the storage system, click the [Add] button.

   → The [Add Allowable IP Address] Screen appears.

4. Input the IP address and the subnet mask, and then click the [OK] button.

   → Returns to the [Setup Network Environment] screen.

5. Repeat Step 3 and Step 4 when registering multiple allowable IP addresses.

6. After registering the allowable IP address is complete, click the [Set] button.

   → A confirmation screen appears.

   Caution

   • When specifying the IP address or the subnet mask, note the following:

     • IP addresses must be specified with the IPv4 format.

     • The IP address of the RMT port must be in a different subnetwork from the MNT port.

     • Specify the IP address of the Slave CM when connecting to the Slave CM. The IP address of the Slave CM must be in the same subnetwork as the Master CM.

     • Specify the IP address of "Gateway" when allowing access from outside of the subnetwork. The IP address must be in the same subnetwork as the port.

     • For "Allowable IP Address", specify the IP address or the network address that is allowed to access to the storage system. These settings are not required for access from the network address (same subnetwork) which the storage system belongs to.

     • For "DNS", specify different IP addresses for the MNT port and RMT port.

   • Click the [Clear] button to delete setting parameters. Note that the parameters cannot be deleted if no other ports are available.

7. Click the [OK] button.

   → The network environment settings starts.

8. Click the [Done] button to return to the [Network] screen.

   Caution

   • Storage system management operation cannot be continued if the IP address of the storage system has been changed. Logging in again with the new IP address is required.

When Using IPv6

1. Select which port that the network environment is to be set for, and click [Setup Network Environment] in [Action].

2. Specify the parameters.

   Note

   • Click the [Automatic discovery] button to automatically obtain "Master IP Link Local Address", "Master Connect IP Address", "Slave IP Link Local Address", "Slave Connect IP Address", "Length of Subnet Prefix", and "Gateway". Input the IPv6 address of the DNS server if required.

3. To allow access from a different subnetwork to the storage system, click the [Add] button.

   → The [Add Allowable IP Address] Screen appears.

4. Input "Connect IP Address" and "Length of Subnet Prefix", and click the [OK] button.

   → Returns to the [Setup Network Environment] screen.

5. Repeat Step 3 and Step 4 when registering multiple allowable IP addresses.

6. After registering the allowable IP address is complete, click the [Set] button.

   → A confirmation screen appears.

   Caution

   • Note the following points when specifying an IP address:

     • IP addresses must be specified with the IPv6 format. Refer to "IPv6 Address Notation" for details.

     • The connect IP address of the RMT port must be in a different subnetwork from the MNT port.

     • Specify the connect IP address of the Slave CM when connecting to the Slave CM. The IP address of the Slave CM must be in the same subnetwork as the Master CM.

     • Specify the IP address of "Gateway" when allowing access from outside of the subnetwork. The IP address must be in the same subnetwork as the port.

     • For "Allowable IP Address", specify the IP address or the network address that is allowed to access to the storage system. These settings are not required for access from the network address (same subnetwork) which the storage system belongs to.

     • For "DNS", specify different IP addresses for the MNT port and RMT port.

   • Click the [Clear] button to delete setting parameters. Note that the parameters cannot be deleted if no other ports are available.

7. Click the [OK] button.

   → The network environment settings starts.
