General Information on setting up your DS300 for network connection

DS300 Setup

The following sections provide general information on setting up your DS300 for connection to the network using the Command Line Interface (CLI).

 

DS300 factory defaults

 

The factory default settings for the DS300 are as follows.

 

  Hostname: DS300

  Domain Name: ibm.com

  Timezone[GMT]: GMT-5

  New Administrator password: passw0rd (the o in password is the number 0)

  Default Gateway: 0.0.0.0

  DNS servers: NO

  Use DHCP: NO

  Management i/f IP address: 192.168.70.12X 

  Management i/f IP netmask: 255.255.0.0

  Management i/f broadcast address: 192.168.255.255

 

Management port (ETH0) IP setup

 

The factory default IP address for the management port for Controller A is 192.168.70.123 (ETH0[A]). The management port for Controller B defaults to 192.168.70.124 (ETH0[B]).  If you want to change these addresses, establish a Telnet session to the respective management port. Once connected, the CLI prompt will appear. For additional information on the CLI see Using the CLI.

 

Alternately the CLI can be run from a terminal session by connecting to the left most serial port jack. Use serial cable FRU PN 13N1792 (not supplied). The terminal settings are as follows:

Baud Rate:115,200

            Data Bits: 8

            Parity: None

            Stop Bits: 1

Flow Control: Off

 

Note: You need to be in administrator mode to change the IP addresses. Default PW is PASSW0RD (zero – not an O)

 

CLI example to set up a new IP address for the management port

 

Make sure you are in administrator mode.  To check the current settings of the port (ETH0[A]) do the following:

 

DS300[A]> ad     (log in as administrator)

DS300[A]# interface manage eth0[A] info

 

----[ Interface 'eth0[A]' ]-------------------------------------------------------

            Services:  management

    Alternative name:  eth0[A]

              Status:  Enabled

         MAC address:  00:00:D1:DD:B6:8C

          DHCP DISABLED

          IP address:  192.168.70.123

             Netmask:  255.255.0.0

           Broadcast:  10.1.0.255

                 MTU:  1500

               Speed:  AUTO

 

Note: Make sure the Status is “Enabled” and DHCP is disabled to set static addresses.

 

To set up a new address:

 

DS300[A]# interface manage eth0[A] ip 192.168.100.54

Please wait.

Interface values are now:

          IP address:  192.168.100.54

   Broadcast address:  192.168.255.255

             Netmask:  255.255.255.0

 

The IP address for the management station has been changed to 192.168.100.54. If you want to make this address permanent, save the configuration.

 

DS300[A]> administrator  (if not already in ad mode)

DS300[A]#  save

 

After the next enclosure reboot (or power cycle) the new IP addresses will be permanent.

 

Important: Do not assign the iSCSI ports to the same subnet as the management interface (except for RL model).  In addition, each iSCSI port needs to be on a different subnet.

 

Setting up iSCSI port  IP addresses

 

To set iSCSI port IP addresses, perform the following general steps:

 

1.      Connect the management port to a system.

Note: Ensure that the system NIC is set up with the same subnet as the management port and that the NIC link speed and that of the management port are the same.

2.      Start a Telnet session to connect to the controller management port and to access the Command Line Interface (CLI).  Refer to the following figure for port identification.

 

3.      From the CLI prompt, set the IP addresses as shown in the following example.

Note:  The IP addresses given are samples.

 

DS300[A]# administrator

DS300[A]# interface info

----[ Interface 'eth2' ]-------------------------------------------------------

            Services:  iscsi

    Alternative name:  eth2

              Status:  Enabled

         MAC address:  00:00:D1:DD:B2:66

          DHCP DISABLED

          IP address:  xxx.xxx.xxx.xxx

             Netmask:  255.255.255.0

           Broadcast:  10.1.0.255

                 MTU:  1500

 

Note: Make sure that the Status is Enabled and that DHCP is disabled to set static addresses.

Note: Failover requires that the iSCSI port IP address be static. Do not enable DHCP if you have a failover configuration

 

 

DS300[A]# interface manage eth2 ip 191.1.9.2

Please wait.

Interface values are now:

          IP address:  191.1.9.2

   Broadcast address:  10.1.0.255

             Netmask:  255.255.255.0

 

DS300[A]# interface manage eth3 ip 181.1.8.4

Please wait.

Interface values are now:

          IP address:  181.1.8.4

   Broadcast address:  10.1.0.255

             Netmask:  255.255.255.0

 

 

  1. To verify that the IP addresses have been successfully set up and that the IP stack is operational, use the interface list command from a CLI prompt, as shown in the following example. This command shows the settings of the ports. Verify that the addresses are set correctly. Now perform the Diagnostic Verification.

 

 

DS300[A]# interface list

eth0[A]             192.168.100.54   management

eth2             191.1.9.2        iscsi

            eth3             181.1.8.4        iscsi

 

Diagnostic verification

 

IP Stack verification

 

Note: When running the following test, do not connect any cables to the iSCSI ports.

 

Use the commands shown in the following example to verify that the IP addresses for the management ports are set correctly.

 

 

DS300[A]# diag ping 191.1.9.2 count 4 interface eth0[A] [pinging from eth0[A] to eth2]

Crossport connection test

 

Perform the crossport test to verify the ETH ports functionality. Connect an Ethernet cable (straight through) from ETH2 to ETH3. If you are accessing the CLI via the serial port you can also connect ETH0[X] to the other ports.

 

Syntax

 

diag connection <from> <to>

 

'from' and 'to' are the interfaces (i.e. eth0[A], eth2, eth3) and must be specified. The same interface may be used as 'from' and 'to'.

 

The test either reports success or failure.

 

IP connection verification

 

To check that the IP addresses have been successfully set up and that there is an active connection do the following:

 

  1. Connect a HOST NIC to the port and perform a ping to the IP address you set up.

 

 

If the DS300 has a second controller, repeat the procedure shown above.

After you have set up and verified the IP addresses, continue with the PD maps.

Note: In a dual controller enclosure, it is recommended that a single Telnet session be active to only one controller. The management of both controllers can take place through that single connection. You can log on to a controller from the current controller session by doing a “Controller Set”. See Using the CLI – Controller Commands.
