Chapter 2. Installing the storage subsystem This chapter provides the information about installing the storage subsystem into a rack cabinet. Before you begin the installation, review the safety information in “Safety” on page xi and “Handling static-sensitive devices” on page 19. “Installation overview” on page 18 provides an overview of the entire DS3200 installation process. Read this overview before you begin the installation.
If an item is missing or damaged, contact your IBM marketing representative or authorized reseller. Instructions for installing the DS3200 in a rack cabinet are provided in the Rack Installation Instructions. To connect your DS3200 to other devices, use the following options, which must be purchased separately: v IBM IM SAS cable v IBM 3M SAS cable v Host bus adapters (HBAs) in the hosts Installation overview CAUTION: >18 kg (39.7 lb) or or 18-32 kg (39.7-70.
Attention Before you power-on the storage subsystem, it must contain at least four drives. If at least four drives are not installed in each attached storage expansion enclosure and in the DS3200 storage subsystem, when you power-on the DS3200 and its attached storage expansion enclosures, your standard storage partition key might be lost and you must regenerate it, using instructions at http://www.ibm.com/storage/fasttkeys/.
v While the device is still in its static-protective package, touch it to an unpainted metal part of the system unit for at least 2 seconds. This drains static electricity from the package and from your body. v Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on your system unit cover or on a metal surface.
v Rack power jumper cords that come with the DS3200 v Rack-mounting hardware that comes with the DS3200 v SAS cables (1-meter or 3-meter) Preparing the site This section lists the floor space requirements and weight information for the DS3200. For information about interface cables and connections, see Chapter 3, “Cabling the storage subsystem,” on page 23.
22 System Storage DS3200 Storage Subsystem: Installation, User’s, and Maintenance Guide
Chapter 3. Cabling the storage subsystem After the storage subsystem is installed in its permanent location, you must cable it to hosts, drives, and other external devices, depending on your hardware configuration. SAS controller connectors Figure 13 shows controller A, the host ports, and the drive expansion port at the rear of a single-controller DS3200 storage subsystem. Controller A Host port 1 Drive expansion port Figure 13.
Enclosure ID settings The controller automatically sets the enclosure ID number. You can change the setting through the storage management software, if necessary. Both controller enclosure ID numbers are identical under normal operating conditions. The allowable range of enclosure ID settings is 0 through 99. However, for best results, do not set the enclosure ID to 00 or any number less than 80. The DS3200 enclosure ID is normally set to a value of 85 at the factory.
Attention: To avoid damage to the SAS cables, consider the following precautions: v When you route the cable along a folding cable-management arm, leave enough slack in the cable. v Route the cable away from places where it can be damaged by other devices in the rack cabinet. v Do not put excess weight on the cable at the connection point. Make sure that the cable is well supported. To connect a mini-SAS cable, insert the mini-SAS connector into a mini-SAS port. Make sure that it locks into place.
To remove a mini-SAS cable, complete the following steps: 1. Put one finger into the hole on the blue plastic tab on the mini-SAS connector and gently pull on the tab to release the locking mechanism. Blue plastic tab Figure 17. Removing a mini-SAS cable 2. As you pull on the tab, pull out the connector to remove it from the port. Connecting storage expansion enclosures to the DS3200 Attention Before you power-on the storage subsystem, it must contain at least four drives.
System Storage DS3000 Support CD. Incorrect drive migration might cause loss of configuration and other storage subsystem problems. Contact your IBM technical-support representative for additional information. Redundant drive channel pair Each RAID controller on the DS3200 has a drive expansion channel that contains an x4 SAS port. The storage expansion enclosures that are connected to this connector form a drive channel.
Overview of steps to connect storage expansion enclosures to a storage subsystem To connect storage expansion enclosures to the storage subsystem, complete the following steps: 1. Follow the instructions in the Installation, User's, and Maintenance Guide for your storage expansion enclosure and the Rack Installation Instructions to set up and mount the storage expansion enclosures. 2.
One single-controller DS3200 and one or more storage expansion enclosures To cable one single-controller DS3200 to one or more single-ESM storage expansion enclosures, connect them as shown in Figure 19. DS3200 RAID controller A SAS cable EXP3000 To DS3200 RAID controller A SAS cable EXP3000 SAS cable EXP3000 Figure 19.

Connect the other end of the SAS cable to the In port on the left ESM in the storage expansion enclosure. 7. Connect one end of a second SAS cable to the Drive expansion port on Controller B in the DS3200 storage subsystem. 8.
Upgrading a single-controller to a dual-controller when there is no attached EXP3000 enclosure If you are upgrading a single-controller DS3200 storage subsystem to a dual-controller DS3200 storage subsystem and there are no EXP3000 storage expansion enclosures attached to the DS3200 storage subsystem, see “Installing a controller” on page 64.
Important: 1. To minimize security risks, do not connect the DS3200 to a public LAN or public subnet. Use a local private network for the DS3200 and the management station Ethernet connectors. 2. For proper EMI shielding, always use quality braided and shielded serial cables.
Connect an Ethernet cable from the management station to the Ethernet connector on controller A on the rear of the storage subsystem. For a dual-controller storage subsystem, you can connect a second Ethernet cable from the management station to the Ethernet connector on controller B. Figure 23 shows the locations of the Ethernet management connectors on the DS3200 storage subsystem. Controller A Ethernet connector Controller B Ethernet connector Figure 23.
Host-agent (in-band) management method This method requires that host-agent software be installed on the host server. The host-agent software enables the DS3000 Storage Manager client program to manage the DS3200 storage subsystem by using the same connections between the host server and the storage subsystem. You must install at least one management station and a software agent host. The management station can be the host or a workstation on the Ethernet network.
Host computer SAS I/O path Controller Controller Storage subsystems Ethernet Management station (one or more) Figure 25. Direct (out-of-band) managed storage subsystems Installing the storage subsystem configuration Using the information from the previous sections, install the host systems and host bus adapters (HBAs). Notes: 1. See the documentation that comes with the HBAs for installation requirements and procedures. 2. Use the correct HBA device driver.
To connect a SAS host bus adapter (HBA) to the DS3200 storage subsystem, complete the following steps: 1. Connect a SAS cable from the DS3200 RAID controller host port to the SAS HBA that is in the host. Figure 13 on page 23 shows the location of the DS3200 host ports. 2. Create a redundant host connection: v If the DS3200 is a single-controller storage subsystem, connect a SAS cable from the second SAS HBA to another host port on the DS3200 RAID controller.
The following illustration shows a direct-attached SAS connection to dual HBAs in a single-host (redundant host connection). Host system with dual host adapters DS3200 Figure 27.

Chapter 4. Operating the storage subsystem This chapter describes operating procedures for the DS3200. To ensure optimal operation of the storage subsystem, see “Best practices guidelines” on page 6. Performing the DS3000 Health Check process The DS3000 Health Check process is a sequence of suggested actions that were developed by IBM to help you verify and maintain the optimal performance of the DS3200 storage configuration.
4. Use the Storage Subsystem Profile or DS3000 Profile to make sure that the following functions are enabled: v For all DS3000 models, enable Media Scan both at the controller level and at the LUN level. v For all DS3000 models, enable the read/write cache. In addition, use the Storage Subsystem Profile to make sure that cache is matched between the controllers.
The following procedure addresses two situations: v The entire storage subsystem has been shut down (the main circuit breakers for the rack cabinet are off). v Some storage expansion enclosures are being powered-on while others remain online (the main circuit breakers for the rack cabinet are on). You might encounter this if you are adding a storage expansion enclosure to increase storage capacity. Attention: 1.
each storage enclosure powers-on, the green and amber LEDs on the front and rear of the storage expansion enclosure turn on and off intermittently. The cache battery backup self-test might take up to an additional 15 minutes to be completed. During this time, the LEDs on the front and rear of the storage subsystem might flash intermittently. 6. Determine the status of all storage subsystems and components in the configuration by completing the following steps: a.
Before any planned system shutdown or after any system additions, removals, or modifications (including firmware updates, logical drive creations, storage partitioning definitions, hardware changes, and so on), save the storage subsystem profile as explained in the DS3000 Storage Manager guide for the operating system. Save the profile in a location other than the logical drives that are created for the DS3200.
For example, the recovery procedure for a PFA flag (impending drive failure) on a drive varies depending on the drive status (hot spare, unassigned, RAID level, current logical drive status, and so on). Depending on the circumstances, a PFA flag on a drive can indicate a high risk of data loss (if the drive is in a RAID 0 volume) or a minimal risk (if the drive is unassigned). Only the DS3000 Storage Manager software can identify the risk level and provide the necessary recovery procedures.
Attention: Failure to observe the limitations, prerequisites, sequences, and dependencies in the readme file might result in a loss of data access. Unless the readme file contains special requirements for the sequence in which you upgrade firmware, perform firmware upgrades in the following sequence: 1. ESM firmware for the storage expansion enclosures 2. Controller firmware 3. Controller NVSRAM 4.
Checking the LEDs The LEDs indicate the status of the storage subsystem and components. Green LEDs indicate a normal operating status; amber LEDs (needs attention) indicate a possible failure; a blue LED on a component indicates that it is safe to remove that component. The DS3200 also has a blue system locator LED that is lit when the menu function is selected in the Subsystem Management window, causing the Locate command to be sent to the DS3200.
Front LEDs This section describes the primary LEDs and controls on the front of the DS3200 storage subsystem. Hard disk drive activity LED Hard disk drive status LED Power-on LED System Storage System locator LED Overtemperature LED System error LED Figure 35. Front LEDs and controls Power-on LED (green) When this green LED is lit, it indicates that the power supply is turned on and is supplying both 5-volt and 12-volt dc power to the DS3200.
If the optional SAS host port adapter is installed in the RAID controller, the host port adapter contains two additional SAS host connectors with LEDs. SAS link up SAS link service action SAS link service action SAS link up Figure 37. Host port adapter LEDs SAS link service action (amber) When this LED is lit, it indicates a problem with the SAS link that requires service action. The normal condition of this LED is off.
Turning off the storage subsystem The DS3200 is designed to run continuously. After you turn it on, do not turn it off. Turn off the power only in the following situations: v Instructions in a hardware or software procedure require that you turn off the power. v An IBM technical-support representative instructs you to turn off the power. v A power outage or emergency situation occurs, see “Restoring power after an unexpected shutdown” on page 57.
Power-off overview Review the following information before you continue with the power-off procedure: Turn off the power to each device according to the following shutdown sequence: 1. Turn off power to the host before the storage subsystem. If the host must stay powered-on to support a network, see the operating-system documentation for information about disconnecting the storage subsystem logical drives from the host before the storage subsystem is powered-off. 2.
c. When the recovery procedure is completed, click Recheck in the Recovery Guru. This action runs the Recovery Guru again to make sure that the problem is corrected. d. If the problem has not been corrected, contact your IBM technical-support representative. Do not turn off power until all problems are corrected. 5. Check the cache active LED, and make sure that it is off. If the cache active LED is lit, the cache contains data. Wait for the data to clear from cache memory before you turn off the power. 6.
v Yes: Do not continue with this procedure. Contact your IBM technical-support representative for assistance. Depending on the current service agreements, you might have to return the equipment to the factory or local service center for repair. v No: Go to step 2. Attention: To avoid potential data loss, make sure that the storage subsystem and storage expansion enclosure power switches are turned off before you reset circuit breakers in the rack cabinet.
v v v v v An unusually high room temperature Fan failures in the power-supply units Defective circuitry in a power supply Blocked air vents Failures in other devices in the configuration or rack cabinet If a fan failure causes overheating, the system-error LED and overtemperature LEDs on the storage subsystem are lit. The fault LED on the power supply might also be lit. “Checking the LEDs” on page 52 shows the location of the LEDs on the DS3200.
v No: Go to step 6. 6. Turn off both power switches on the DS3200 (see Figure 33 on page 47) and then power-off all connected storage expansion enclosures. Wait 1 minute and then turn on power to all connected storage expansion enclosures. While a storage expansion enclosure powers-on, the LEDs on the front and the rear of the enclosure flash intermittently. Depending on your configuration, the storage expansion enclosure can take between 20 seconds and several minutes to power-on. 7.
Cache memory Cache memory is memory on the RAID controller that is used for intermediate storage of read and write data on the DS3200 RAID controllers. Using cache memory can increase system performance. The data for a read operation from the host might be in the cache memory from a previous operation (thus eliminating the need to access the drive itself), and a write operation is completed when it is written to the cache, rather than to the drives.
If the battery fails the learn-cycle test, the battery fault LED is lit, indicating a battery fault, and a Defect Battery error message is displayed in the event log. In the Storage Manager software, if the battery age timer indicates that the battery is 2 years old, but the battery is not reported as failed, do not call your IBM technical-support representative to replace the battery. Instead, reset the battery age by using the procedure that is described in the Storage Manager software online help.
Chapter 5. Replacing components This chapter contains information about replacing the storage subsystem components. It also contains information about installing an optional SAS host port adapter in a RAID controller. Attention: Always replace a failed component as soon as possible. The Recovery Guru in the DS3000 Storage Manager software identifies failed components. Service action allowed LED Each controller and power supply has a blue service action allowed LED.
3. Disconnect all attached interface cables from the failed controller. Be sure to label each cable so that you can reconnect it correctly. 4. Remove the controller from the chassis. Handle Guide pin Notch Figure 38. Removing a controller a. On the left side of the controller, press the orange release tab to the right just enough to release the handle; then, rotate the handle upward. b. Slowly pull the handle away from the chassis to remove the controller from the bay, as shown in Figure 38. c.
4. Start the command-line interface; then, enter the following command to change controller A from simplex (single-controller) mode to duplex (dual-controller) mode: Smcli ctlr_A_IP_address -c "set storageSubsystem redundancyMode=duplex;" 5. Shut down the storage subsystem, and then start it again (see “Turning on the storage subsystem” on page 46). If controller A was successfully converted to duplex mode, the subsystem reports an alternate controller missing error message.
12. Make sure that all storage expansion enclosure connections with each other have been completed (see the dual-controller topologies in “DS3200 storage subsystem drive cabling topologies” on page 28); then, connect the SAS drive expansion cable from the right ESM in the last storage expansion enclosure in the chain to the drive expansion port on controller B of the DS3200. 13. Wait up to 5 to 10 minutes for the DS3000 Storage Manager software to report the drives and the redundant drive path. 14.
5. Is the service action allowed LED lit? v Yes: Go to step 6. v No: Another component might require attention before you can remove the controller. Use the Recovery Guru in the DS3000 Subsystem Management window to identify and correct any additional failures. If there are none, proceed with step 6 to replace the controller.

Attention Before you power-on the storage subsystem, it must contain at least four drives. If at least four drives are not installed in each attached storage expansion enclosure and in the DS3200 storage subsystem, when you power-on the DS3200 and its attached storage expansion enclosures, your standard storage partition key might be lost and you must regenerate it, using instructions at http://www.ibm.com/storage/fasttkeys/.
Removing a hard disk drive To remove a hot-swap hard disk drive, complete the following steps. Note: The hard disk drive comes installed in a drive tray. Do not attempt to detach the drive from the tray. 1. Use Table 9 on page 110 to record the location and identify the hard disk drives. Record this information so that you can replace the hard disk drives in the same bays from which you removed them. 2. Read the safety information that begins on page xi and “Best practices guidelines” on page 6.
Installing a hard disk drive Except during the DS3200 storage subsystem initial power-on, you can add hard disk drives while the storage subsystem is turned on and running. To install hot-swap hard disk drives in the storage subsystem, complete the following steps. Attention: After you remove a drive, wait 70 seconds to allow the drive to spin down before you replace or reseat the drive. Failure to do so might cause unpredictable results. Note: The hard disk drive comes with a tray already attached.
This includes transmission problems between the host controllers and the drives. This section explains how to replace a failed hard disk drive. Note: If you want to remove a hard disk drive that is not in a failed or bypass state, always use the Storage Manager software either to place the drive in a failed state or to place the array that is associated with the drive (or drives) in an offline state before you remove the drive from the storage subsystem.
8. Make sure that the drive is shown in the DS3000 Storage Manager Subsystem Management window. Note: If you are replacing more than one hard disk drive, replace only one drive at a time. Replacing multiple drives This section provides guidelines for upgrading the drives in the storage subsystem.
v Which method most closely matches the recommended drive upgrade procedure that is provided in the operating-system or storage-management software documentation. v Which RAID level is used on the affected drives (RAID 0 requires you to replace all the drives at the same time). v How much downtime is acceptable as you swap the drives. v The number of drives in an array. Replacing drives one at a time is better suited to arrays that consist of three to five drives.
Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling static-sensitive devices, see “Handling static-sensitive devices” on page 19. 4. Unpack the new drives. Set the drives on a dry, level surface away from magnetic fields. Save the packing material and documentation in case you have to return the drives. 5. Complete the following steps: a.
enclosures, turn on the power-supply switches on the rear of the storage subsystem. You must turn on both power-supply switches to take advantage of the redundant power supplies. 10. Check the green drive activity LEDs and the amber drive fault LEDs above the new drives. Make sure that the drive activity LEDs are lit and the drive fault LEDs are off. Note: The drive fault LEDs might flash intermittently while the drives spin up. v If a drive activity LED is off, the drive might not be installed correctly.
Set the drives on a dry, level surface away from magnetic fields. Save the packing material and documentation in case you have to return the drives. 5. Use the DS3000 Storage Manager software to make sure that the array that was defined using these drives is in Optimal (not Degraded) state before you manually fail the first drive that you want to replace. If the array is in a Degraded state, use the recovery procedures to bring the array into the optimal state.
9. When reconstruction is finished on the new drive, repeat step 5 on page 81 through step 8 on page 81 for each additional drive that you want to install. 10. Use the DS3000 Storage Manager software to configure the additional space on the new drives.
