See Hardware Protection.
PS6610 Hardware Owner's Manual 1 Basic Storage Array Information • Use telnet or SSH to connect to a functioning IP address assigned to a network interface on the array. Do not connect to the group IP address. • Use the null modem cable, shipped with the array, to connect the serial port on the active control module (ACT LED is green) to a console or a computer running a terminal emulator.
PS6610 Hardware Owner's Manual 1 Basic Storage Array Information 5. After performing array maintenance, you can turn on power to the array. When the array restart completes, the member and volumes will be set online.
2 Drive Maintenance You can replace a failed drive while the array remains running. Supported Drives and Drive Types Depending on your configuration, your array supports either 42 or 84 of the 2.5-inch and 3.5-inch SAS nad NL-SAS drives in internal drive bays. SSD drives are also supported in a hybrid configuration. Drives are connected to the midplanes and backplane through drive carriers and are hot-swappable. Drives are supplied in a carrier that is keyed to fit into a specific array model.
PS6610 Hardware Owner's Manual • • • • • • 2 Drive Maintenance Protect drives from electrostatic discharge. Wear an electrostatic wrist strap when handling a drive. See Hardware Protection on page 6. Store drives properly. Store replacement drives in the packaging in which they were shipped. Do not stack drives or place anything on top of a drive. Handle drives carefully. Hold a drive only by the plastic part of the carrier or the handle. Do not drop, jolt, or force a drive into a slot.
PS6610 Hardware Owner's Manual 2 Drive Maintenance Array Behavior When a Drive Fails The PS6610 firmware uses a copy-to-spare operation to replace failing drives. This operation can, in many cases, improve the performance of the drive replacement process by avoiding a full RAID rebuild, which provides better reliability. Note: If a drive fails, replace it. Do not reinstall it in the array. If a replacement drive is not available, keep the failed drive in the array until it can be replaced.
PS6610 Hardware Owner's Manual 2 Drive Maintenance Table 7: Drive LED States Item 1 Description Drive status indicator (LED) Indicator States • Off — Drive OK • Amber — Drive failed • Blinking — Drive identification Installing and Removing Disk Drives The proper insertion and seating of hard drives in the chassis drawers is critical to the operation of the array. For proper cooling, do not remove a failed drive until it can be replaced with another.
PS6610 Hardware Owner's Manual 2 Drive Maintenance Figure 8: Inserting a Drive in the Drive Bay Figure 9: Securing a Drive in the Drive Bay 4. Verify that the new drive is operational by examining the LED on top of the DDIC. (An amber LED indicates that the drive is working properly.) In addition, you can examine the GUI group member Disks tab and the CLI member select show disks command output to check the status of all drives in the system.
PS6610 Hardware Owner's Manual 2 Drive Maintenance Remove Disk Drives Note: Removing a drive is easier if you work from the side of the open drawer. 1. Using two hands, apply firm downward pressure to the top surface of the drive carrier. 2. While maintaining downward pressure, use one finger to press the release button on the center of the carrier and push it in the direction of the arrow (callout 1 in Figure 10). The drive latch opens and the drive will emerge partway from the array.
3 Control Module Maintenance The control modules in a PS Series array contain the PS Series firmware, which provides the Group Manager GUI, the command-line interface (CLI), and all the array and storage management functions and features. Ideally, an array has two control modules (which must be of the same type) to avoid a single point of failure for the array. The PS6610 array includes two hot-swappable Type 18 control modules. One functioning control module is required for array operation.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Dual Controller Configuration A dual control module configuration eliminates a single point of failure in the array. If the active control module fails, the secondary control module takes over automatically with no interruption of service. This automatic transition gives you time to replace the failed control module while your volumes and data remain accessible.
PS6610 Hardware Owner's Manual • 3 Control Module Maintenance Above the release latch is a column of three LEDs that indicate the status of the entire control module. See Table 9.
PS6610 Hardware Owner's Manual LED Name ERR PWR 3 Control Module Maintenance State Off Description Normal operation or no power Steady red Array is starting up, in error condition, in Standby mode, or returning from Standby mode. Blinking red Array is entering power standby mode because the Standby On/Off button was pressed. Off On (steady green) No power Power/OK Identify Control Module Failures You can identify a failure in a control module by: • LEDs on the control module itself.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Control module failover occurs automatically, and if iSCSI initiators reconnect to the group IP address, application I/O can continue without user intervention. Control Module Firmware Maintenance Each control module has a microSD card running the array firmware. You should run the latest firmware version to take advantage of new product features and enhancements.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Figure 13: Standby Button Location Enable the Standby Feature To use the standby button, a group administrator must enable the feature in the Group Manager GUI or CLI. Enabling the use of the button applies groupwide; that is, it allows you to press the button to shut down any member (array) that has the standby button (PS4100, PS4110, PS6100, PS6110, PS6210, and PS6610 array models).
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Using the Standby On/Off button on one member does not affect any other group members, with the exception of the group lead member. When the group lead member is in standby mode, it takes a few minutes for the group lead to fail over to another member. You must press the standby button on each member to restore power to the member that is in standby mode.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance 1. Shut down the system with a full shutdown, as described in Shutting Down and Restarting an Array on page 6. 2. Replace the control module, as described in Replacing the Secondary Control Module on page 21. 3. Remove and swap the battery from the existing control module to the replacement control module, as described in Battery Replacement on page 27. 4. Use the restart command to make the active control module secondary. 5.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Figure 14: Removing a Control Module 3. Place the control module on a flat surface where it will be protected from electrostatic discharge. To avoid damage, do not place anything on top of the control module. 4. If you are replacing a failed control module, remove the microSD card from the failed control module and install it in the replacement control module.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Figure 15: Correct Control Module Orientation 1. Attach an electrostatic wrist strap or similar protective device. See Hardware Protection on page 6. 2. Pull up on the orange release tab (callout 2 in Figure 16) and swing the lever out. 3. Slide the control module (callout 1 in Figure 16) into the chassis until it is even with the installed controller. The lever should swing smoothly until it is in the locked position.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance If two control modules are installed in the array, but only one is shown in the GUI (or CLI), make sure that you have allowed enough time (minimum of 5 minutes) for the two control modules to boot and synchronize. When synchronization completes, a message appears on the serial console (if connected), and the ACT LED on the secondary module is illuminated amber.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Caution: To reduce the risk of losing or damaging the microSD card, do not remove it until you are ready to install it in the replacement control module. 1. Firmly push the card into its housing to release the spring mechanism (see Figure 17). The microSD card will become partially ejected from the housing. 2. Gently pull the card straight out of the housing. 3.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Figure 18: Inserting the MicroSD Card 3. Install the control module in the array. See Install a Control Module on page 23. 4. Ensure the control module is operational. See Interpreting Control Module LEDs on page 16. Battery Replacement This section describes the steps that must be followed when replacing the battery in a PS Series array control module. Note: Many repairs must be done only by a certified service technician.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Note: If the screw falls inside the control module, you might have to return the control module to Dell for servicing. 4. Using the screw tab as a handle, swing the battery cover up and to the left and lay it upside down on the control module (Figure 20). The battery cover will be heavier than expected because the battery is attached to the cover. Figure 20: Removing the Battery Cover 5.
PS6610 Hardware Owner's Manual 3 Control Module Maintenance Insert the New Battery 1. Attach the new battery unit to the connector, and gently wiggle and push the connector in place to seat it. You do not need to depress the retention clip to insert the connector. When the connector is fully seated, you should hear the retention clip click into place. 2. Place the new battery unit in the chassis by reversing the procedure from step 5 for removing the battery.
4 Maintain Power Supply Units The array supports two hot-swappable power supply units. The array is capable of operating with one power supply temporarily, but both power supplies are required to maintain long-term reliability of the array. About Power Supplies The PS Series array receives power from two power supply units (PSUs). The array can run on one supply while the other is in a failed state. Each unit has a 2800W power supply that requires 200-240VAC high AC line power source.

Hold the power supply unit so that the orange release latch is on the upper left (callout 1 in Figure 24. 2. Slide the power supply unit into the chassis until it is fully seated and the release latch clicks into place, as illustrated in Figure 24.
PS6610 Hardware Owner's Manual 4 Maintain Power Supply Units Figure 24: Inserting a Power Supply 3. Ensure the power switch is in the OFF position. 4. Connect the power cable to the power supply and cooling module and plug the cable into a power outlet. Note: The AC LED lights up when the power cable is connected, even if the switches on the power supply are off. 5. Secure the power cable using the hook-and-loop fastener strap, as shown in Figure 25. 6. Turn on the power switch on the power supply unit.
5 Maintain Fan Modules The PS6610 array contains five cooling fan modules. The array is capable of operating with one failed fan module; however all five cooling modules are required to maintain long-term cooling and reliability of the array. Remove a Cooling Fan Module Although an array can operate with only four working fan modules, you should replace the failed fan unit as soon as possible. For proper array cooling, do not remove the failed fan unit until you are ready to replace it.
PS6610 Hardware Owner's Manual 5 Maintain Fan Modules Install a Cooling Fan Module Caution: Do not allow the array to operate for more than 2 minutes without a fan module in place to maintain proper cooling of the array. How to Install a Cooling Fan Module Wear electrostatic protection when handling a cooling module. See Hardware Protection on page 6. To insert a cooling module: 1. Hold the cooling modules so that the orange tab is in the upper right (callout 2 in Figure 27). 2.
6 Advanced Networking Options In addition to connecting all the Ethernet ports (of the same type) on both control modules to network switches, you can also optionally connect the management port to a separate network switch. Configuring a management port enables you to separate management traffic (creating and managing the group, members, volumes, replication, and so on) from the iSCSI data traffic (I/O between applications and volumes, and between replication partners).
