To manage the ETERNUS DX series with this software, set up devices while keeping in mind the points listed below.
See
Refer to the ETERNUS Web GUI manual supplied with the respective device for settings details.
Community setting in SNMP (Agent) environment settings
This product communicates with an ETERNUS Disk storage system using SNMP. The SNMP Community name that this product uses for SNMP communication is specified when the ETERNUS Disk storage system is registered. If the SNMP Community name setting is default, this product communicates with the ETERNUS Disk storage system by "Community name: public". Therefore, the Community name on the ETERNUS Disk storage system side should be set to either of the following step a and b. Also, the Community name can be changed to other than "public". When using other than the default Community name, follow step c below for the device and set the Community name for this product from the Web Console.
In addition, for ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series, set "ViewALL" in the MIB view to the Community name.
Community is not set. (default)
Many devices have "public" (Access: read Only, address: all hosts, and view: all Object) set as the default SNMP Community access.
However, the ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series have no default SNMP Community access. Access must be explicitly enabled. Enable access by following either step b or step c below.
Specify "public" for the Community name explicitly.
In this case, specify either the IP address of the Management Server on which Manager is installed or 0.0.0.0 (to receive messages from all hosts) as the IP address.
Specify other than "public" for the Community name explicitly.
Add the Community name and specify the Management Server's IP address. However, when the manager is running in a clustered system, the manager communicates with ETERNUS by using the physical IP address of the clustered system. Therefore the Community setup is described by the same number as the physical IP addresses.
Example
"ssc" Is Specified Community Name for SNMP Communication with Management Server (IP Address: 10.10.10.10):
community ssc 10.10.10.10
"ssccom" Is Specified Community Name for SNMP Communication with Management Server Operating as Clustered 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
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 Management Server can be received. Even in an environment where the Community name is specified other than default, 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.
In the ETERNUS Disk Storage system, if the number of the SNMP Trap transmission destination is set to the maximum number of register, no new IP address can be added. Therefore, make sure that the number of SNMP Trap transmission destination is less than the maximum number.
Device name setting (SysName) in SNMP (Agent) environment settings
Register a nickname for storage management. This software uses this value as SysName.
When changing the device name while AdvancedCopy Manager CCM is in use, refer to "Changing Registered Information for ETERNUS Disk Storage System" in the ETERNUS SF AdvancedCopy Manager Operation Guide for Copy Control Module to change the registered information.
Network environment settings
If the Management Server resides outside the location indicated by the IP address, subnet mask, gateway, and subnet, the subnet of the Management Server must be registered as the destination network address.
Point
When Management Server Is in Cluster:
If you specify the IP address of the Management Server as a destination network address, specify both physical IP address of each node on the Management Server in a cluster and IP address taken over.
Generation of SSH server key (ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series only)
Execute the generation of the SSH server key needed for the SSH communication between this software and the devices.
The bit number of the SSH server keys is arbitrary.
Creation of Software role account (ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series only)
Create an account for this software to manage a device.
Note the following restrictions about the account.
The root user cannot be used it to manage this software.
The account should be a software role.
Select Software as the user level when creating the account
Specify this account information when you register a device in this product.
If the user name and password are changed on the device side after having been registered to this product, the device information cannot be properly collected nor configured from this product.
Change the device management account information in the Web Console to make it match with the change in settings made on the device side.
SSL Certificate generation or registration (ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series only)
This product uses an HTTPS connection to manage the storage devices (default).
In order to be able to use a HTTPS connection with the storage devices, choose one of the following settings:
Create Self-signed SSL Certificate Setting
Register SSL Certificate Setting
Logoff
Be sure to log off from the ETERNUS Web GUI after completing the setup in the ETERNUS Web GUI.
You must be logged off from the ETERNUS Web GUI in order to perform registration of the device to this product.

Information
For this software, the host access control function of ETERNUS Disk storage system is called "host affinity function", and zone numbers are called "AffinityGroup numbers".
To use this software to set the server node and storage access path (the SAN environment containing the Fibre Channel switch), refer to "6.2.3.1 Preparations". The following settings must also be configured in the device.
The following settings can be set up from this product, so it is not necessary to perform setup from the device side.
RAID Settings
Storage's AffinityGroup/Zone Settings
Connection Configuration Settings
Host Interface Settings
HostWWN Definition
HostWWN-AffinityGroup/Zone Definition
To set the date-time for the device, perform the procedure shown below. If the date-time is set during performance monitoring, briefly stop performance monitoring and then restart it.
Stop performance monitoring of the device for which date-time is set.
Set date-time for the device.
After the date-time settings are complete, restart performance monitoring of the device.
To change the configuration for the device, the device configuration information kept by performance management must be updated. Update the configuration information according to the procedure in "7.2.9 Updating Configuration Information".
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.
This software may be unable to automatically detect the device if SNMP Trap transmissions are set to a specific server but a server which has Manager operating on it is not set as the SNMP Trap transmission destination. Check the settings for the SNMP Trap transmission destination.
If the SNMP Community name is changed and Manager is in the cluster environment, settings on the storage device side may be incorrect. Refer to "Changing SNMP Community Name" given below.
Check that there are no problems with the settings for the storage device and its network environment. This includes network environment settings, access permission settings, transmission mode settings, and so on. Refer to the section "4.3.1.1 Setting" for network settings. For transmission mode settings, if transmission mode on one side of the connection is "Auto Negotiation" and "FULL (full duplex)" on the other, transmissions may being unable to be sent or slow down, so make sure that the transmission mode is set correctly.
The name of the SNMP Community used for SNMP transmission is specified when registering the ETERNUS Disk Storage system. If the SNMP Community settings are at their defaults, 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 Disk Storage system other than ETERNUS DX80 S2/DX90 S2, DX100 S3/DX200 S3, DX400 S2 series, DX500 S3/DX600 S3 and DX8000 S2 series, "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 storage devices is to be changed, storage device settings are required.
Refer to step 1 "Community setting in SNMP (Agent) environment setting" in "4.3.1.1 Setting".
Check that there are no problems with the settings for transmission mode in the storage device and its network environment. For transmission mode settings, if transmission mode on one side of the connection is "Auto Negotiation" and "FULL (full duplex)" on the other, transmissions may being unable to be sent or slow down, so make sure that the transmission mode is set correctly.
When the device is under the maintenance, the status displayed with this software might be different from an actual status of the device.
If the redundant copy function was running on ETERNUS DX60/DX60 S2/DX80/DX90, the overall status on the ETERNUS Web GUI is "Error", but "Warning" is displayed by this software.
