Powering OnThis section explains how to turn on the ETERNUS DX.

To turn on the ETERNUS DX, perform the following procedure.

• Via the power switch

Press the Power switch to turn on the ETERNUS DX.

The following methods can be used to turn the power on by linking with the server.

• Power Synchronized Unit

Use the power synchronized unit to turn on the ETERNUS DX.

• Wake On LAN

Use the Wake On LAN function to turn on the power.

Before turning on the ETERNUS DX, make sure that the main line switches of the power distribution units andthe PSU switches on the power supply units of the ETERNUS DX are "ON". Do not turn the main line switches ofthe power distribution units and the PSU switches on the ETERNUS DX to the OFF position.

• After turning on the power of the ETERNUS DX, it takes approximately five minutes (or approximately 10minutes for a Unified configuration and approximately 20 minutes for a VLAN/Bonding maximum configu-ration) to reach the READY state (the READY LED turns on). If an error is detected in a component duringthe initial power-on diagnostics, it may take a maximum of 10 minutes (or a maximum of 11 minutes for aconfiguration in which the Deduplication/Compression function is enabled, approximately 40 minutes for aUnified configuration, and approximately 50 minutes for a VLAN/Bonding maximum configuration) for theETERNUS DX to reach the READY state. If a scheduled operation is being performed, make configurations bytaking the operation into consideration.

• Before turning the server on, check that the ETERNUS DX and the network devices that connect the ETER-NUS DX and the server are all in READY status.

If the server is turned on while any of these devices are not in READY status, the server may not be able torecognize the ETERNUS DX.

• To turn on the ETERNUS DX by linking with the server, the server must wait until the ETERNUS DX is in theREADY state.

• If the Auto Power function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX is automatical-ly turned on when power is supplied to the ETERNUS DX.

• If the Power Resume function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX is automat-ically turned on after the power is restored.

• After power-off, wait for about one minute before turning power on again.

• If the ETERNUS DX is not turned off normally due to problems such as a power failure, it takes approximate-ly five minutes (max.) longer to reach the READY state the next time the ETERNUS DX is turned on.




This section explains how to use the Power switch to turn on the ETERNUS DX.

For other procedures, refer to the related manuals.

1 Press the Power switch of the controller enclosure.


Power switch

The POWER LEDs on the controller enclosure and the drive enclosures are turned on.

2 After approximately five minutes (or approximately 10 minutes for a Unified configuration and approxi-mately 20 minutes for a VLAN/Bonding maximum configuration), check that the READY LED of the control-ler enclosure is lit up.


Drive enclosure

Powering OffThis section explains how to turn off the ETERNUS DX.

To turn off the ETERNUS DX, perform one of the procedures below.

• Via power switch

Press the Power switch to turn off the ETERNUS DX.

• Via ETERNUS Web GUI or ETERNUS CLI

Use ETERNUS Web GUI or ETERNUS CLI to turn off the ETERNUS DX.

The following methods can be used to turn off the power by linking with the server.

• Via the power synchronized unit

Use the power synchronized unit to turn off the ETERNUS DX.




• When turning off the ETERNUS DX, the power shuts off after the write data on the cache memory is writtenback to the drives. As a result, it may take approximately five minutes (or approximately 10 minutes in aUnified configuration and 20 minutes in a VLAN/Bonding maximum configuration) or a maximum of 10 mi-nutes (or approximately 40 minutes in a Unified configuration and 50 minutes in a VLAN/Bonding maxi-mum configuration) for the power supply to be completely turned off.

• Do not turn off the power of the ETERNUS DX and the network devices that connect the ETERNUS DX to aserver while the server is operating. This may result in the loss of data or prevent data from being saved inthe ETERNUS DX.

• When using a power synchronized unit for power control, turn off the power of the ETERNUS DX via the pow-er synchronized unit. When a power synchronized unit is connected, the power of the ETERNUS DX is auto-matically turned on because the power synchronization function is activated.

• To turn off the ETERNUS DX100 S4/DX200 S4, use the Power switch, a power synchronized unit, ETERNUSWeb GUI, or ETERNUS CLI. If any other method is used to turn off the ETERNUS DX, the replacement cycle forthe battery is shortened significantly because the battery continues to charge and discharge.

• After power-off, wait for about one minute before turning power on again.

This section explains how to use the Power switch to turn off the ETERNUS DX.

For other procedures, refer to the related manuals.

1 Press and hold the Power switch of the controller enclosure for four seconds or more.


Power switch

The READY LED on the controller enclosure is turned off.

Press the Power switch only once. If the Power switch is pressed again between the time of the READYLED turning off and the POWER LED turning off, the ETERNUS DX power may turn on.

2 The power of the ETERNUS DX is disconnected.

When the power is disconnected, the POWER LED of the controller enclosure and the POWER LEDs of thedrive enclosures are turned off.




Using the FUNCTION ButtonThis section explains how to use the FUNCTION button of the controller enclosure.

The following settings can be performed by using the FUNCTION button:

• Switching the Master CM to the other controller

For the two controllers in the ETERNUS DX, the controller through which the ETERNUS DX is set up and oper-ated is called the "Master CM", while the other controller is called the "Slave CM". The single-controller typeonly has a "Master CM" controller.

• Restoring the factory default settings (network environment settings and firewall settings) of the LAN ports

• Restoring the factory default user settings (user account, role, and RADIUS settings)

The following procedure explains how to use the FUNCTION button.

1 Remove the flange cover of the controller enclosure.

2 Change the status of the ETERNUS DX to maintenance status.

Use the pin to push down the FUNCTION button for three seconds.

The ETERNUS DX is in maintenance status when the MAINTENANCE LED is green.

2. Basic OperationUsing the FUNCTION Button



3 Use the FUNCTION button to change settings.

• Switching the Master CM to the other controller when two controllers are installed

Use the pin to push down the FUNCTION button twice within three seconds.

The MASTER LED for the controller that is set as the Master CM is green.

• Restoring the factory default settings of the LAN ports

Use the pin to push down the FUNCTION button three times within three seconds.

After the default settings of the LAN ports are restored, the MAINTENANCE LED blinks green a few times asecond for several seconds.

• Restoring the factory default user settings

(1) Remove all the LAN cables from the LAN ports (MNT ports and RMT ports) of all the controllers.

6. Maintenance

This chapter describes maintenance once the ETERNUS DX starts to be operated.

Periodic BackupIn case of an unexpected problems, important data should be regularly backed up.

Do

• We recommend that you backup important data regularly. If the ETERNUS DX fails andthe data has not been backed up, it may be lost.

Maintenance ServiceThis section explains the ETERNUS DX maintenance service.

When performing maintenance service, the maintenance engineer connects a PC used for maintenance to theETERNUS DX. Also, the maintenance engineer may require information that is necessary for performing main-tenance operations. If the maintenance engineer has any requirement, we ask that they be handled.

Maintenance Support PeriodThe standard maintenance support period for ETERNUS DX is five years from the date of purchase, or is definedin your service level agreement (SLA). Contact your sales representative for details if you prefer to extend theperiod.

Replacing BatteriesThe batteries of the ETERNUS DX100 S4/DX200 S4 are expendable components that need to be replaced periodi-cally.

Batteries can be replaced during regular maintenance free of charge. For customers without a maintenance con-tract, replacement requests (payment required) must be made.



■ Replacement Cycle for a Battery

If a battery is used at an average temperature of 25 °C, the battery can be used for the entire maintenance sup-port period (five years). The replacement cycle for a battery varies according to the customer's environment andusage.

Do

• The replacement cycle for a battery is shortened if the battery is used at high tempera-tures or the battery charges and discharges frequently.

■ Checking the Time to Replace the Battery

• If the time to replace the battery is near, contact your maintenance engineer to re-place the battery. If the battery is still used even after the replacement time haspassed, the performance of the ETERNUS DX100 S4/DX200 S4 degrades because theoperational state of the cache is changed to Write Through mode.

The time to replace the battery can be checked by using the following options.

If the time to replace the battery is near, contact your maintenance engineer.

• Check the time to replace the battery by using ETERNUS Web GUI or ETERNUS CLI.

• If the time to replace the battery is near, a notification is sent via an e-mail or an SNMP trap message.

- A notification is sent six months before the expiration date.

- A notification is sent everyday for a week before the expiration date.

To switch the Master CM, perform one of the following procedures.

- Using the FUNCTION button to switch the Master CM

Push down the FUNCTION button twice within three seconds during maintenance to switch the Master CM toanother controller.

- Using ETERNUS Web GUI to switch the Master CM

If the IP address for the Slave CM is specified, access to the Slave CM IP address via ETERNUS Web GUI toswitch the Master CM is performed.

• Have any network devices (such as LAN switch or router) failed? Are the network device settings invalid?

• Are the environment settings for the network service invalid?

• Is the IP address incorrect?

• Are the settings for the ETERNUS DX LAN ports (firewall) invalid?

If the problem is not resolved, follow the procedure below to restore the default values for the ETERNUS DXnetwork environment settings and the firewall settings.

Note that the settings (network environment settings and firewall settings) for all of the LAN ports are initial-ized after the following procedure is performed.

1 Remove the flange cover of the controller enclosure.




2 Change the status of the ETERNUS DX to maintenance status.


The ETERNUS DX is in maintenance status when the MAINTENANCE LED is green.

3 Use the pin to push down the FUNCTION button three times within three seconds.

After the default settings of the LAN ports are restored, the MAINTENANCE LED blinks green a few times asecond for several seconds.

4 Release maintenance status.


The MAINTENANCE LED turns off.

5 Access ETERNUS Web GUI or ETERNUS CLI by using the default IP address to perform the network environ-ment settings and the firewall settings.

Make sure to enable the firewall setting for the protocol that is used for each service.

• To use ETERNUS Web GUI, enable the http or https connection. If the connection is disabled, the ETER-NUS DX cannot connect to the network via GUI.

• To use ETERNUS CLI, enable the telnet or SSH connection. If the connection is disabled, the ETERNUSDX cannot connect to the network via CLI.

• To use the "ping" command for the ETERNUS DX, enable the ICMP connection. If the connection is disa-bled, the ETERNUS DX does not respond to the "ping" command.

• To use monitoring software, enable the Maintenance Secure connection. If the connection is disabled,the ETERNUS DX cannot connect to the network via monitoring software.

• To use the SNMP Manager, enable the SNMP connection. If the connection is disabled, the ETERNUSDX does not respond to SNMP access.

6 Check whether each service can connect to the ETERNUS DX.

If it cannot connect, contact your maintenance engineer.




■ When I/O Access Is Slow

Check the points that are shown below. When the cause is not identified, contact your maintenance engineer.

• Check the battery status of the ETERNUS DX100 S4/DX200 S4 by using ETERNUS Web GUI. If the battery chargerate is low or if the replacement time for a battery has passed, the performance of the ETERNUS DX degradesbecause the operational state of the cache is changed to Write Through mode.

If the replacement time for a battery has passed, contact your maintenance engineer.

• Check that the ambient temperature does not exceed the operating environment conditions.

If the ambient temperature exceeds the operating environment conditions, Nearline SAS disk performancemay be reduced.

• Click the icon of each part on the [Storage] screen of [Component] of ETERNUS Web GUI to check if an abnor-mality is detected in ETERNUS DX parts.

If an abnormality is detected, contact your maintenance engineer.

• Check the path status.

- If the ETERNUS Multipath Driver is used, start ETERNUS Multipath Manager.

If an abnormality is detected in a path, refer to the ETERNUS Multipath Driver manuals and follow the direc-tion given in the manuals.

- If the ETERNUS Multipath Driver is not used, check the path status by using the path management tool thateach software provides and handle any problems as required.

• Check the loading of the ETERNUS DX. If the load is out of balance because of operation content changing orfor other reasons, review the configuration and settings.

• Check the transfer rate of the FC port.

If the transfer rate for the ETERNUS DX is different from the server or the FC switch, set the same transfer rateas the server or FC switch.

• Check the number of command queues in the server.

When there are no problems in the process capacity of the server, adjust the number of command queues sothat the I/Os are issued for the appropriate number.

For details on the number of command queues, refer to "Configuration Guide -Server Connection-".

• Check the message log of the OS on the server that is connected and then take the appropriate actions.

• Check the status of the RAID group.

When rebuild/copyback or redundant copy is being performed in a RAID group with a "High" rebuild priority,the performance may be reduced until the operation is complete.

• Check the cache parameter settings of the volumes.

The performance may be reduced when multiple sequential read accesses simultaneously occur for volumesthat do not have the Force Prefetch mode enabled. Enable the Force Prefetch mode and specify the appropri-ate value for the Prefetch Limit.

This may be caused by accesses that are used for video distribution businesses.




■ When the Server Does Not Recognize the Volumes


• Check the status of the ETERNUS DX and other devices such as network devices connecting the server and theETERNUS DX, and ensure that there are no problems with the power supply.

• Check if an error occurs in a path by using a path management tool such as ETERNUS Multipath Manager. Re-fer to the relevant manuals and take the required actions.
