4.3.1 Disk array ETERNUS8000, ETERNUS6000, ETERNUS4000, ETERNUS3000, ETERNUS2000, ETERNUS DX60/DX80, ETERNUS VD800, GR


4.3.1.1 Setting

To manage the ETERNUS8000 series, the ETERNUS6000 series, the ETERNUS4000 series, the ETERNUS3000 series, ETERNUS2000 series, ETERNUS DX60/DX80 and GR series with this software, set up devices while keeping in mind the points listed below. Read the term "ETERNUS VD800 disk array unit" in this manual as "ETERNUS3000 series".

See

For settings details, refer to the ETERNUSmgr/GRmgr User's Guides supplied with ETERNUSmgr/GRmgr of each device, such as the "ETERNUSmgr User's Guide," "GR710/GR720/GR730 GRmgr User's Guide," and "GR740 GRmgr User's Guide".

For the GR820 or GR840, GRmgr must be purchased separately.

  1. root password setting

    Set the root password for logging in to ETERNUSmgr/GRmgr.

  2. Community setting in SNMP (Agent) environment settings

    This software communicates with the GR/ETERNUS product by using "public" for the Community name at an initial value. Therefore, the Community name setting on the GR/ETERNUS product side must be either of the ones explained below a and b. Note that the Community name can be changed. For information on changing the Community name, see below c and "SNMP_COMMUNITY_NAME_FOR_IP" parameter in sanma.conf at "Appendix C Customization".

    1. Any Community is not set. (initial)
      "Public" (Access: read Only, address: all hosts, and view: all Object) is set by an initial value.

    2. Specify "public" for the Community name explicitly.
      In this case, specify either the IP address of the administrative server on which Manager is installed or 0.0.0.0 (to receive messages from all hosts) as the IP address.

    3. Specify other than "public" for the Community name explicitly.
      The administrative server is specified with the Community name and the administrative server's IP address. However, when the manager is running in a cluster system, the manager communicates with ETERNUS/GR by using the physical IP address of the cluster system, therefore the Community setup are described by the same number as the physical IP addresses.

      Example

      "ssc" is the specified Community name for SNMP communication with the operation management server (IP Address: 10.10.10.10):

      community ssc 10.10.10.10

      "ssccom" is the specified Community name for SNMP communication with the operation management server operating as a cluster system operation (physical IP_A: 10.10.10.11, physical IP_B: 10.10.10.12):

      community ssccom 10.10.10.11
community ssccom 10.10.10.12

  3. Trap setting in SNMP Agent Configuration Setting

    Since the manager's SNMP Trap receiving module has not judged this Community name, all SNMP Traps sent to the administrative server can be received. Even in an environment where the Community name is specified other than "public", it is not necessary to change this community name in trap setting. The Community name of the trap destination is recommended to be set as "public", not same as the Community name of SNMP Community under the consideration of security.

    If the maximum number of SNMP Trap transmission places of the ETERNUS/GR is already registered, no new IP address can be added. Therefore, make sure that the number of SNMP Trap transmission places is less than the maximum number.

  4. Device name setting (SysName) in SNMP (Agent) environment settings

    Register a nickname for storage management. This software uses this value as SysName.

  5. Network environment settings (excluding the GR740, GR820, GR840)

    If the administrative server resides outside the location indicated by the IP address, subnet mask, gateway, and subnet, the subnet of the opration management server must be registered as the destination network address.

    Point

    When an administration server is in a cluster:

    If you specify the IP address of an administration server as a destination network address, specify both physical IP address of each node on administration servers in a cluster and IP address taken over.

  6. Logoff

    After completing definition of the settings with ETERNUSmgr/GRmgr, be sure to log off from ETERNUSmgr/GRmgr. In the ETERNUS8000, ETERNUS6000, ETERNUS4000 and ETERNUS3000 series, ETERNUS2000 series, ETERNUS DX60/DX80, or in GR710/720, the registration of devices in this software and use of the Storage Volume Configuration Navigator device setup function are only possible when not logged onto ETERNUSmgr/GRmgr.

Note

Access paths can be set from this software even while a user is logged in to ETERNUSmgr(ETERNUS6000, ETERNUS4000 models 80 and 100, ETERNUS3000)/GRmgr. If a change to access path settings is made simultaneously from both ETERNUSmgr/GRmgr and this software, configuration information of the device may be destroyed. Therefore, when changing access path settings from this software, make sure that no setting change operation is in progress on the ETERNUSmgr/GRmgr side.

Information

For this software, the host access control function of ETERNUS disk array devices and GR series devices is called "host affinity function", and zone numbers are called "AffinityGroup numbers". Defining them with more global names such as these makes it possible to address future multivendor device management needs. For definitions of other names, see "A.1 Notational Conventions of Window Elements and Abbreviations".


To use this software to set the server node and storage access path (the SAN environment containing the Fibre Channel switch), refer to "6.3.3.1 Preparations". The following settings must also be configured in the device.

RAID settings

RAID group/LogicalVolume setup is executed using Storage Volume Configuration Navigator or ETERNUSmgr/GRmgr. For storage devices not supported by Storage Volume Configuration Navigator, execute the setup using ETERNUSmgr/GRmgr.
For details about Storage Volume Configuration Navigator, refer to "11.1.5 Operation procedure".

Affinity Group/Zone settings for storage

AffinityGroup/Zone is created in the storage device using Storage Volume Configuration Navigator or ETERNUSmgr/GRmgr. For storage devices not supported by Storage Volume Configuration Navigator, create AffinityGroup/Zone using ETERNUSmgr/GRmgr.
For details about Storage Volume Configuration Navigator, refer to "11.1.5 Operation procedure".

4.3.1.2 Problem-handling (FAQ)

Unable to detect ETERNUS8000, ETERNUS6000, ETERNUS4000, ETERNUS3000, ETERNUS2000, ETERNUS DX60/DX80, or GR series

  • This software uses SNMP communication to find devices. Therefore, a storage device whose SNMP function is inactive cannot be detected. The storage device's SNMP function must be started.
    Press the <Set> button in the ETERNUSmgr/GRmgr SNMP environment setting window. The SNMP function is started by once pressing the <Set> button. Therefore, if the <Set> button is not pressed at all, the SNMP function remains inactive.

  • If the server running the manager is not defined as a destination server on the server running SNMP trap transmission, auto-detection may not work. If this is the case, check the SNMP trap transmission settings and make sure the server running the manager is defined.

  • If the SNMP community name is changed and Manager is in the cluster environment, settings on the storage device side may be incorrect. See "Changing SNMP community name" given below.

  • Check the network environment, access authorization and communication mode settings referring to section "4.3.1.1 Setting" for details. Make sure that one communication mode is not set to "Auto Negotiation" while the other is set to "Full (full duplex)"

Unable to detect GR740, GR820, GR840

  • Check whether GRG (GRGateway) is active on the maintenance PC. If it is inactive, execute GRG.exe. Also, register GRG.exe in the Startup menu.

  • If the SNMP community name is changed and Manager is in the cluster environment, the settings on the storage device side may be incorrect. See "Changing SNMP community name" given below.

Changing SNMP community name

This software implements SNMP communication using the community name public by default. If "Set SNMP Agent Environment"-"Set Community" is not set at all for ETERNUS and GR storage devices, "public" (access: readOnly, address: all hosts, view: all objects) has been set as the initial value. If at least one community is set, this software communicates with only the specified community settings.
When the SNMP community name for the ETERNUS and GR storage devices is to be changed, storage device settings are required.
See "2. Community setting in SNMP (Agent) environment setting" in "4.3.1.1 Setting".

Timeout occurs in communication.

Check the communication settings and make sure that one communication mode is not set to "Auto Negotiation" while the other is set to "Full (full duplex)".
