Removing and replacing fans This section describes how to remove and replace fans.

Fan overview This topic provides information to assist in servicing the fan FRU. Each storage processor s six dual counter-rotating fan modules (fan) in a 5+1 redundancy configuration. The six fans pull air into the system from the front of the enclosure, past the disk drives, through holes in the midplane and into the storage processor, through the fans, then across the U and other system board components, through holes in the I/O Risers, then across the I/O boards and power supplies, then the air exits out the back of the system The six fans are located in the storage processor and the system must be powered down and the storage processor removed for service. The system can run indefinitely with a single fan failed. A storage processor will be automatically powered down within two minutes of determining that there is an ambient air over-temp condition or multifan failures. 12



Fan modules are removed by squeezing the two retaining tabs together towards the center of the fan and pulling the fan upward

Identify the failed fan The following figure shows the orientation of the six fans at the front of the chassis.

Procedure 1. The SP fault LED, at the upper left rear of the chassis, is lit amber if there is a fan failure. 2. Use the alerts show current (or alerts show current-detailed) command that will include messages indicating fan loss or fan failure. # alerts show current Alert Id Alert Time ----------------------51 Tue May 17 22:15:34 2016 -----------------------

I/O modules This section describes how to remove and replace the I/O modules.

I/O module overview Several I/O modules can be used. This topic explains how and why the I/O modules are used. I/O modules are form-factor I/O adapters that provide high speed, low latency I/O solutions to the PCI express bus. I/O modules provide host and DAE interface options for the system. All I/O modules share common design features: l

I/O modules may be x4 or x8 gen1, gen2, or gen 3 PCI Express compatible

l

Each I/O module has a bi-color green and amber LED to indicate normal and faulted status, respectively

l

Power consumption for a single wide I/O module does not exceed 35 Watts.

I/O modules insert into the I/O risers from the rear of the SP module. A slot that does not contain an I/O module must have a filler installed in its empty slot. The filler is plastic with a metal face plate, and retains electromagnetic radiation inside the device. This is required for EMI compliance and better airflow impedance for system cooling.

2.5" disk drives This section describes how to remove and replace 2.5" disk drives. The drive slot/locations are marked on the chassis 0-1, but the DD OS software still references the slots as 13-14. It is important to identify the proper drive between the location called out in the FRU, and the location as specified in the software.

2.5" Disk Drive Overview The rear of the enclosure s up to two 2.5" SAS SSD drive carriers that slide into 2.5"drive bays. The rear of the enclosure s up to two 2.5" SAS SSD drive carriers that slide into 2.5" drive bays. For AIO configurations, these drive slots must use 1 SSD and the expanded configuration must use 2 SSDs. For DLH configurations, these slots are never populated with drives. The SAS SSD carrier has a lever mechanism that aligns and secures the drive in place. The lever is secured by a slide latch. When the slide latch is slid down, the latch handle pop up and is lifted up to release the SAS SSD carrier. To secure the latch handle, push it down and move the slide latch up to capture the handle. For all configurations that do not populate all the rear 2.5" drive slots with 2.5" drive carriers, 2.5" drive fillers must be installed. The plastic 2.5" drive filler slides into the 2.5" drive bays. The filler is simply pushed into the drive slot where it snaps into place. Depressing the top filler latch and providing a firm pull of the filler removes it from the slot.

50



Identifying a failed disk drive The 2.5" SSDs are inserted vertically in the back of the chassis, in slots labeled 0 and 1.

Each drive has a status LED and a marker LED.

1. Status LED 2. Marker LED Procedure 1. Use the disk show state command to display the status of all disk drives. # disk show state 2. Locate the failed disk in the system. A steady amber LED light on a disk drive indicates that the disk has faulted.

Installing a 3.5" disk drive Note

If you are replacing more than one disk, replace one disk at a time so the system does not attempt to simultaneously rebuild multiple drives. To install a disk: Procedure 1. Attach an ESD wristband to your wrist and the enclosure in which you are installing the disk. 2. Insert the disk in the slot as follows: a. With the disk's latch fully open, gently push the disk into the slot. (1) The latch begins to rotate to the right when its tabs meet the enclosure. b. Push the handle inward to engage the latch (2).

the replacement 3.5" drive The system reports the state of a replacement disk drive depending on the history of the disk. Use the disk show state command to display the state of all disk drives. A replacement disk drive that is inserted into the system is recognized as a failed disk drive and is noted as failed when first installed. An auto-spare process should change the status to spare in a few minutes. Procedure 1. Use the following command to check that the disk drive is recognized by the Data Domain system. In the command display, the disk State should be spare or reconstructing. # disk show state Enclosure Disk 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ----------------------------------------------------1 s . . . .

3. Generate an auto when the disk drive replacement is completed. Issue the following command from the command line interface: # auto send

Chassis A replacement chassis includes only the metal shell and midplane. It will be necessary to move the following parts from the old chassis to the new chassis: l

Bezel

l

Solid state drives (SSD)

l

Hard disk drives (HDD)

l

Storage processor (SP) module, moved as a unit, which includes: n

Fan assemblies

n

Air duct

n

Memory DIMMs and memory risers

n

Power supplies

n

Standard and optional SAS, Ethernet, and Fibre Channel (FC) I/O modules, depending on the system model

l

NVRAM module

l

Blank fillers for empty I/O module slots

Preliminary and troubleshooting steps The chassis replacement procedure includes a series of commands that rediscover the data stored on the external shelves. Procedure 1. Before replacing the chassis, it is beneficial to run the following commands and save the output on the Data Domain system that is to be replaced. Use this information to that the procedure has completed successfully: # # # # # # # # # #

58

storage show all disk show state disk show hardware system show ports disk multipath status filesys show space enclosure show topology vtl show config vtl group show all enclosure show power supply



Note l

When you run these commands before and after the chassis replacement, the output should be the same. Save this information in case any configuration problems are found after the procedure has completed.

l

See the Data Domain Operating System Command Reference Guide for detailed information about these commands.

Chassis replacement procedure Note l

Only trained and qualified service engineer should be allowed to install or replace this equipment.

l

Before removing the chassis, label all cables attached to the chassis so that the cables can be reconnected correctly after the chassis replacement.

l


Data Domain recommends putting the current chassis and the new chassis on an ESDfree work surface that is large enough for the new and old systems to be side-by-side on a table or counter top to ensure the correct placement of all components in the new chassis. CAUTION

If it is necessary to replace both the chassis and the SP module, do not replace at the same time. Important configuration information can be lost. In this instance, you must do a serial swap in which the SP module is replaced first, the system is booted, the system is brought down, and then the chassis is replaced.

Shut down and disconnect the system Procedure 1. Stop the system using the system poweroff command to allow the proper shut down of the file system and other system components. Note

The system poweroff command completes when the front blue LED turns off. For help connecting to a system using a laptop computer and terminal emulator, see the document FE Toolkit Inventory and Common Procedures for FRU Tasks at https://.emc.com. 2. Label each of the cables as to their connection location. Taking a photograph for reference is also helpful for re-connecting the cables. 3. Disengage the wire clips, then disconnect both AC power cords from the rear of the system. Chassis replacement procedure

Powering off an unresponsive system Follow these instructions if it is not possible to power off the system using the system poweroff command, for example, if the system becomes unresponsive. Procedure 1. Locate the recessed power button on the back of the management , indicated by two facing triangles. 2. Using a ballpoint pen or the end of a paperclip, press and hold the button for ten seconds.

Chassis replacement This procedure describes how to replace a chassis. Procedure 1. Remove the CMA, if applicable. 2. Remove the SP. 3. Loosen the two captive screws that attach the node to the front of the cabinet. 4. Pull the chassis from the cabinet and move it to the work area. 5. Install the SP into the chassis. 6. Remove the disk drives from the current chassis and install them into the new chassis. 7. Move the serial number pull-out tag as follows: a. Grasp the edge of the serial number pull-out tag, located in the upper left hand front of the current chassis. b. Pull out on the tag. Some force may be needed to remove the tag. c. Insert the tag into the new chassis. 8. Install the chassis into the cabinet as follows: a. From the front of the cabinet, align the rear of the chassis with the lip of each installed rail. b. Carefully slide the chassis all the way into the cabinet. c. Attach the chassis to the cabinet using two screws. 9. If applicable, install the CMA. 10. Reconnect the cables.

the system and perform a system headswap Procedure 1. If configuration details were captured before the procedure (see Preliminary and troubleshooting steps on page 58), confirm that the new system configuration is complete and accurate. 2. Run the disk rescan command to discover the disks. a. If all of the disks are not listed, perform another rescan. b. If all of the disks are still not listed, reboot the system. 3. Check the disk status by entering: 60

l

The data storage is foreign storage and that there is a complete set of foreign storage available.

4. After ing that the disks are visible by the replacement system as foreign devices, enter: # system headswap

5.

Note

This command might take 30 minutes or longer to complete, depending on the number of shelves and the amount of data on the shelves. After it completes, the system should reboot automatically. again as sys. 6. After the filesystem is up and running, the health of the file system by entering these two commands: # filesys status Note

If the output of this command shows that the filesystem is down, attempt to enable the filesystem using the filesys enable command before entering the filesys show space command.

# filesys show space

7. If the host name of the system changes after the headswap procedure, modify the following as applicable: a. For systems using CIFS: Re- the CIFS domain by issuing the command: # cifs set authentication active-directory domainname

b. For systems with the Replication feature: Use the replication modify commands to update the hostname. the system and perform a system headswap

8. If needed, the functionality of the I/O modules. For specific information, refer to the Data Domain DD6300, DD6800, and DD9300 Field Replacement Unit Guide . 9.

Note

The information is retained in the management module registries and IPMI IDs are in the BMC. You might have to work with the customer to get the new MAC addresses on the network. Enter the ipmi list command to the IPMI s. # ipmi list Name Id -----------ipmi2 3 ipmi1 2 -----------Total s: 2

Privilege ------------ -------------

10. Enter the ipmi change command to change the of an IPMI if needed: # ipmi change ipmi1

11. Because the system disks and Fibre Channel I/O modules are moved from the old chassis to the new chassis, no changes are required for drive mappings or access groups. If such changes are required, however, use the details captured in Preliminary and troubleshooting steps on page 58 to confirm FC I/O configuration. Refer also to the Data Domain System Controller Upgrade Guide for more information.

Bring HA back online For HA systems, bring the HA configuration back online. Procedure 1. Run the ha online command on the standby node to bring the HA configuration back online. 2. For HA systems that were failed over to the standby node before the component replacement, optionally fail the system back to the original active node. Run the ha status command to that the HA pair can failover and the ha failover on the current active node to restore the original active node.
