Setting Up the ETERNUS DX

2.1 Common Settings

This section explains the settings required for all server OSes, regardless of the connection configuration.

See the "ETERNUS Web GUI User's Guide" for details of how to set up and operate ETERNUS Web GUI.

2.1.1 Setting the To-server Connection Type (Setting the SAS Port Parameters)

For each connection configuration, set the indicated items only. All other parameters should be left on their

default values.

Table 2.1 SAS port parameter settings

Parameter Solaris OS, Windows®, Linux, VMware ESX

Reset Scope I_T_L (Default value)

Release Reservation if Chip is Reset Disable (Default value)

2.1.2 Creating the Server Accessible LUN Groups (Setting the LUN Groups)

Create LUN groups (Affinity Group) for the server to access. Refer to "Connectivity (Basic Information)" in

"ETERNUS Web GUI User's Guide" for details, and set the LUN groups.

When the server OS is Windows®, Linux, or VMware ESX, assign SCSI LUN numbers starting from LUN0 in

ascending order.

The server cannot recognize the ETERNUS DX LUNs unless they are assigned in this order.

This restriction does not apply when the server is running a Solaris OS.

2.1.3 Setting the Host Responses

The host response parameters for the ETERNUS DX must be set to match the way the server processes the

responses to requests from the ETERNUS DX. Setting of the host response must be done before connecting

the ETERNUS DX to the server.

Set the parameters that are described below for each OS.

Retain the default values for all of the parameters that are not described below.

Since "Windows EMPD", "Linux EMPD", "Solaris EMPD", or "Others" cannot be selected after applying the

latest firmware, select "Default" for the Host Response setting.

Note that these items are displayed as the existing setting, but do not need to be changed.

2.1.4 Setting the CA Port Groups

Create new SAS port groups and register the ports as members of the groups. A SAS port group is a group of

SAS-CA type ports that are connected to the specified host group. Configure the host affinity setting for each

SAS port group.

2.1.5 Registering the SAS Addresses of the Accessing SAS Cards (Setting SAS Host)

same time, set the host response registered in "2.1.3 Setting the Host Responses" (page 9) to accept these

SAS hosts (SAS addresses).

Registering the SAS hosts (SAS addresses) and setting up Host Affinities as described elsewhere, allows limits

to be set on which servers are allowed to access which ETERNUS DX storage systems.

When a server-side SAS card is replaced, the SAS address of the replacement SAS card must be re-regis-

tered to the ETERNUS DX.

1Connect the SAS card that is installed in the server to the ETERNUS DX with the SAS cable.

2Turn on the ETERNUS DX.

3Turn on the server, and start the OS.

4Acquire the SAS address of HBA from each port in the [SAS Host] screen of ETERNUS Web GUI.

5Register the Host Response in which the acquired SAS address is registered to the ETERNUS DX.

2.1.6 Allocating LUN Groups (Setting the Host Affinity)

Allocate the relationship between registered SAS hosts (SAS addresses), CA port groups, and LUN groups us-

ing the Host Affinity setting function to specify which LUNs to be accessed. This sets access restrictions to the

ETERNUS DX from each server.

Refer to "Connectivity (Basic Information)" in "ETERNUS Web GUI User's Guide" for details, and set the LUN

groups.

If the one-to-one relationship between the SAS addresses and SAS cards cannot be determined, the Host

Affinity may not be set correctly.

In this case, trying various settings may be necessary until the server is able to recognize the ETERNUS DX

logical disks.
