    Before turning the server on, check that the ETERNUS DX storage systems and LAN switches are all "Ready". If the server is turned on and they are not "Ready", the server will not be able to recognize the ETERNUS DX storage systems.

  • Page 13: Chapter 4 Checking The Server Information

    Chapter 4 Checking the Server Information The server information registered in the ETERNUS DX should be checked. A variety of commands are used to check the following server information. iSCSI initiator name • Execute the following command: iscsiutil -l The iSCSI initiator name is displayed in the "Initiator Name" column.

  • Page 14: Chapter 5 Setting Up The Eternus Dx

    Setting Up the ETERNUS DX Set up the ETERNUS DX storage systems using ETERNUS Web GUI or ETERNUSmgr. ETERNUS DX setup can be performed independently of server setup. For details on how to perform these set- tings, refer to the following manuals.

  • Page 15: Chapter 6 Installing The Iscsi Software Initiator And Setting Up The Server

    The "iSCSI Software Initiator" package is downloaded. In the "Document" field, click the "Installation Instructions" link. Install the iSCSI Software Initiator according to the displayed installation procedure.

    Name (iqn) or IEEE EUI-64 (eui) format may be used. To set the iSCSI Initiator name, execute the "iscsiutil" command as follows: # iscsiutil [iscsi-device-file] -i -N <initiator-name> FUJITSU Storage ETERNUS DX Configuration Guide -Server Connection- (iSCSI) for HP-UX Copyright 2014 FUJITSU LIMITED P3AM-3402-14ENZ0...

    # iscsiutil -t authmethod CHAP None The above command sets CHAP authentication to operate according to the ETERNUS DX setting. The CHAP authentication method is selected if the ETERNUS DX uses CHAP for its responses, otherwise CHAP authentication is not performed.

  • Page 19: Server Settings When Chap Authentication Is Used

    6.2.4 Server Settings when CHAP Authentication is Used To use CHAP authentication, the following items must be set for the iSCSI ports of the ETERNUS DX and for the iSCSI Initiators. When setting the iSCSI port parameters for the ETERNUS DX, specify the "-I" option and input the IP address.

  • Page 20: Server Settings When Bidirectional Chap Authentication Is Used

    Specify the IP address or hostname of the Network Access Server (NAS). This is the server that is to connect to the ETERNUS DX via the iSCSI interface. The specified IP address or hostname must be for a LAN card that is able to com- municate with the RADIUS server.

    FUJITSU ETERNUS_DXL When the ETERNUS DX storage systems are connected for the first time, the device file (for exam- ple, /dev/dsk/c4t0d0) sometimes may not be created. If this happens, use the "insf" command to create the device file. Specify the hardware path name as follows, and execute.

  • Page 24: Chapter 8 Setting The Multipaths

    Confirm that the PV-Links paths have identical target IDs. • When set correctly, the device files for all paths that connect to a given ETERNUS DX LUN should all be the same after the "t" part of the name (e.g. "/dev/dsk/c4t0d0" g"0d0").
