To manage the ETERNUS DX series, ETERNUS AF All-Flash Arrays, and ETERNUS DX200F 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.
This product can be used for SNMP communication with the ETERNUS Disk storage system using SNMPv1 or SNMPv3.
When using SNMPv3, start from step 2.
SNMP (agent) environment setting when using SNMPv1
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 Web Console.
In addition, for storage devices other than the ETERNUS DX60 S2, 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, storage devices other than the ETERNUS DX60 S2 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. (*1)
Specify other than "public" for the Community name explicitly. (*1)
*1: Select either of the following methods as an SNMP manager when the Community name is set:
Specify the Management Server or select it.
Select this when permitting access from just the Management Server only.
When the Management Server is running in a clustered system, the Management Server communicates with the ETERNUS Disk storage system by using the physical IP address of the clustered system. For this reason, add only the number of physical IP addresses as an SNMP manager.
Specify "0.0.0.0" or keep it unselected.
Select this when permitting access from all the SNMP managers.
Example
"ssc" Is Specified Community Name for SNMP Communication with Management Server (IP Address: 192.0.2.10):
community ssc 192.0.2.10
"ssccom" Is Specified Community Name for SNMP Communication with Management Server Operating as Clustered System Operation (Physical IP_A: 192.0.2.11, Physical IP_B: 192.0.2.12):
community ssccom 192.0.2.11 community ssccom 192.0.2.12
SNMP (agent) environment setting when using SNMPv3
The SNMP user information to be used in SNMP communications with this product is specified when registering the ETERNUS Disk storage system. Because of this, you must set the user for accessing the device side SNMP agent in advance using the "Setup SNMP User" screen of ETERNUS Web GUI.
In addition, set the MIB view for the user that was set at this time from "ViewALL". Refer to the storage device manuals for details on the set method.
When operating the Management Server in a clustered system, you must add the same number of physical addresses in order to communicate with the ETERNUS Disk storage system using the physical IP address of the clustered system.
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.
For the SNMP (agent) environment settings, SNMPv3 Traps can be sent by specifying the name of the user specified in step 2.
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 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 (for storage devices other than the ETERNUS DX60 S2)
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 (for storage devices other than the ETERNUS DX60 S2)
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 Web Console to make it match with the change in settings made on the device side.
SSL Certificate generation or registration (for storage devices other than the ETERNUS DX60 S2)
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 ETERNUS Web GUI after completing the setup in ETERNUS Web GUI.
You must be logged off from ETERNUS Web GUI in order to perform registration of the device to this product.
ETERNUS Web GUI network settings (for the ETERNUS DX60 S2 only)
Under the ETERNUS Web GUI Global Settings tab, click Setup Network Environment in the Network Settings and check the settings for the following items:
Check that "Enable" is specified for Maintenance connections.
Check that "Disable" is specified for Maintenance-Secure connections.
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".
