It provides power to the RAID controller module in the event of a power outage.
Page 35: Storage Array Thermal Shutdown
Storage Array Thermal Shutdown The system automatically shuts down when system temperature exceeds the safe threshold. The battery backup unit protects against data loss by providing power to offload cache to non-volatile memory in the event of power loss. It is not necessary to shut down any MD1200 Series expansion enclosures attached to the storage array when thermal shutdown occurs.
Page 36: Cache Functions And Features
Cache Functions and Features Cache Mirroring Cache mirroring function copies accepted host-write data from the primary controller to the partner controller. This action ensures that host-write data is safely mirrored to the partner controller before successful completion status is returned to the host. If a controller fails, the surviving controller safely retains all mirrored data.
Page 37: Planning: Md3200 Series Storage
Planning: MD3200 Series Storage Array Terms and Concepts This chapter explains the terms and concepts used for configuration and operation of the MD3200 Series storage arrays. Physical Disks, Virtual Disks, and Disk Groups Physical disks in your storage array provide the physical storage capacity for your data.
Page 38: Physical Disks
Physical Disks Only Dell supported 6.0-Gbps SAS physical disks are supported in the storage array. If the storage array detects unsupported physical disks, it marks the disk as unsupported and the physical disk becomes unavailable for all operations. NOTE: The MD3200 Series storage array must contain at least two physical disks for proper operation.
Page 39: Self-Monitoring Analysis And Reporting Technology
Table 4-1. RAID Controller Physical Disk States Status Mode Pending Assigned, Failure Unassigned, Hot Spare in use, or Hot Spare standby Offline Not applicable The physical disk has either been spun Identify Assigned, Unassigned, Hot Spare in use, or Hot Spare standby If a disk drive rebuild fails because of a source drive failure or because the drive is too small, the MDSM reports a failure of the physical disk even...
Page 40: Virtual Disk States
3 Provide host server access. 4 Create mappings to associate the virtual disks with the host servers. NOTE: Host server access must be created before mapping virtual disks. Disk groups are always created in the unconfigured capacity of a storage array. Unconfigured capacity is the available physical disk space not already assigned in the storage array.
Page 41: Raid Level Usage
Using multiple physical disks has the following advantages over using a single physical disk: • Placing data on multiple physical disks (striping) allows input/output (I/O) operations to occur simultaneously and improve performance. • Storing redundant data on multiple physical disks using mirroring or parity supports reconstruction of lost data if an error occurs, even if that error is the failure of a physical disk.
Page 42 RAID 1 RAID 1 uses disk mirroring so that data written to one physical disk is simultaneously written to another physical disk. This RAID level offers fast performance, the best data availability, and the highest disk overhead. RAID 1 is recommended for small databases or other applications that do not require large capacity.
Page 43: Segment Size
Segment Size Disk striping enables data to be written across multiple physical disks. Disk striping enhances performance because striped disks are accessed simultaneously. The segment size or stripe element size specifies the size of data in a stripe written to a single disk. The MD3200 Series array supports stripe element sizes of 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, and 512 KB.
Page 44: Consistency Check
Consistency Check A consistency check verifies the correctness of data in a redundant array (RAID levels 1, 5, 6, and 10). For example, in a system with parity, checking consistency involves computing the data on one physical disk and comparing the results to the contents of the parity physical disk.
Page 45: Virtual Disk Operations Limit
Virtual Disk Operations Limit The maximum number of active, concurrent virtual disk processes per RAID controller module installed in the storage array is four. This limit is applied to the following virtual disk processes: • Background initialization • Foreground initialization •...
Page 46: Virtual Disk Capacity Expansion
Dynamic segment size migration enables the segment size of a given virtual disk to be changed. A default segment size is set when the virtual disk is created, based on such factors as the RAID level and expected usage. You can change the default value (128 KB) if segment size usage does not match your needs.
Page 47: Disk Group Defragmentation
Disk Group Defragmentation Defragmenting consolidates the free capacity in the disk group into one contiguous area. Defragmentation does not change the way in which the data is stored on the virtual disks. Disk Group Operations Limit The maximum number of active, concurrent disk group processes per installed RAID controller module is one.
Page 48: Virtual Disk Migration And Disk Roaming
• Segment size migration • Disk group expansion • Disk group defragmentation The priority of each of these operations can be changed to address performance requirements of the environment in which the operations are to be executed. NOTE: Setting a high priority level impacts storage array performance. It is not advisable to set priority levels at the maximum level.
Page 49 the MD3200 Series storage array does not recognize the migrating metadata and that data is lost. In this case, the MD3200 Series storage array initializes the physical disks and marks them as unconfigured capacity. NOTE: Only disk groups and associated virtual disks with all member physical disks present can be migrated from one storage array to another.
Page 50: Disk Roaming
• Migrating virtual disks to a storage array with no existing physical disks— Turn off the destination storage array, when migrating disk groups or a complete set of physical disks from a storage array to another storage array that has no existing physical disks. After the destination storage array is turned on and has successfully recognized the newly migrated physical disks, migration operations can continue.
Page 51: Host Server-To-Virtual Disk Mapping
Host Server-to-Virtual Disk Mapping The host server attached to a storage array accesses various virtual disks on the storage array through its host ports. Specific virtual disk-to-LUN mappings to an individual host server can be defined. In addition, the host server can be part of a host group that shares access to one or more virtual disks.
Page 52: Snapshot Repository Virtual Disk
For more information on mapping the snapshot virtual disk to the secondary node, see the Dell PowerVault MD3200 and MD3220 Storage Arrays With Microsoft Windows Server Failover Clusters on support.dell.com/manuals. Planning: MD3200 Series Storage Array Terms and Concepts...
Page 53: Virtual Disk Copy
Virtual Disk Copy Virtual disk copy is a premium feature to: • Back up data • Copy data from disk groups that use smaller-capacity physical disks to disk groups using greater capacity physical disks • Restore snapshot virtual disk data to the source virtual disk. Virtual disk copy generates a full copy of data from the source virtual disk to the target virtual disk in a storage array and can be performed either online or offline.
Page 54: Virtual Disk Recovery
Virtual Disk Recovery You can use the Edit host server-to-virtual disk mappings feature to recover data from the backup virtual disk. This functionality enables you to unmap the original source virtual disk from its host server, then map the backup virtual disk to the same host server.
Page 55: Preferred And Alternate Controllers And Paths
The multi-path software identifies the existence of multiple paths to a virtual disk and establishes a preferred path to that disk. If any component in the preferred path fails, the multi-path software automatically re-routes I/O requests to the alternate path so that the storage array continues to operate without interruption.
Page 56: Load Balancing
Ownership can later be modified to balance workload according to actual usage. If virtual disk ownership is not manually balanced, it is possible for one controller to have the majority of the work, while the other controller is idle. Limit the number of virtual disks in a disk group. If multiple virtual disks are in a disk group, consider: •...
Page 57: Monitoring Md3200 Series System Performance
• Least path weight with subset (Windows operating systems only)—The least queue depth with subset policy is also known as the least I/Os or least requests policy. This policy routes the next I/O request to a data path that has the least outstanding I/O requests queued. For this policy, an I/O request is simply a command in the queue.

The Hot Spare Physical Disk Options window is displayed. 4 Select the appropriate option, you can select: • View/change current hot spare coverage—to review hot spare coverage and to assign or unassign hot spare physical disks, if necessary.
Page 116: Global Hot Spares
A hot spare is an idle, powered-on, stand-by physical disk ready for immediate use in case of disk failure. If a hot spare is defined in an enclosure in which a redundant virtual disk experiences a physical disk failure, a rebuild of the degraded virtual disk is automatically initiated by the RAID controller modules.
Page 117: Enclosure Loss Protection
If there are secure disk groups and security capable disk groups in the storage array, the hot spare physical disk must match the security capability of the disk group. For example, a non-security capable physical disk cannot be used as a hot spare for a secure disk group. NOTE: For a security capable disk group, security capable hot spare physical disks are preferred.

Page 225: Management: Firmware Inventory
Management: Firmware Inventory A storage array is made up of many components, which may include RAID controller modules, physical disks, and enclosure management modules (EMMs). Each of these components contains firmware. Some versions of firmware are dependent on other versions of firmware. To capture information about all of the firmware versions in the storage array, view the firmware inventory.

Page 227: Management: System Interfaces
Management: System Interfaces Microsoft Services Virtual Disk Service The Microsoft Virtual Disk Service (VDS) is a component of the Windows operating system. The VDS component utilizes third-party vendor specific software modules, known as providers, to access and configure third-party storage resources, such as MD3200i storage arrays. The VDS component exposes a set of application programming interfaces (APIs) that provides a single interface for managing disks and other storage hardware.
Page 228 VSS attaches to the service and uses it to coordinate the creation of snapshot virtual disks on the storage array. VSS-initiated snapshot virtual disks can be triggered through backup tools, known as requestors. The VSS Provider Configuration Tool offers the following configuration options: •...
Page 229: Troubleshooting: Your Storage
At least two physical disks must be installed in the array. Device Health Conditions When you open the Enterprise Management Window (EMW), the Dell PowerVault Modular Disk Storage Management software (MDSM) establishes communication with each managed storage array and determines the current storage array status.
Page 230 To launch the AMW, perform one of these actions: • On the Devices tab, in either the Tree view or the Table view, double-click a storage array. Alternatively, you can right-click a storage array and select Manage Storage Array from the pop-up menu. On the Setup tab, select Manage a Storage Array.
Page 231 In the Table view, every managed storage array is listed once, regardless of the number of attachments it has in the Tree view. After the storage array is contacted by MDSM, an icon representing its hardware status is displayed. Hardware status can be Optimal, Needs Attention, or Fixing. If, however, all of the network management connections from the storage management station to the storage array shown in the Tree view are Unresponsive, the storage array status is represented as Unresponsive.
Page 232: Storage Array Support Data
Table 18-3. Additional Status Icons Status Icon Adding a Storage Array Adding a Storage Array OK Adding a Storage Array Error NOTE: MDSM may take a few minutes to update a status change to Unresponsive or from Unresponsive. A status change from or to Unresponsive depends on the network link to the storage array.

Page 234: Collecting The Physical Disk Data
Collecting the Physical Disk Data You can use the Collect Physical Disk Data option to collect log sense data from all the physical disks on your storage array. Log sense data consists of statistical information that is maintained by each of the physical disks in your storage array.
Page 235: Recovery Guru
The event log shows two types of event views: • Summary view—Shows an event summary in a table form. • Detail view—Shows details about a selected event. To view the event log: 1 In the AMW, select Advanced Troubleshooting View Event Log. The Event Log is displayed.
Page 236: Storage Array Profile
You can detect a problem using the following indicators: • Non-Optimal status icons • Alert notification messages that are sent to the appropriate destinations • Hardware indicator lights The status icons return to Optimal status as problems are resolved. Storage Array Profile The storage array profile provides a description of all of the components and properties of the storage array.
Page 237 4 To search the storage array profile: Click Type the term that you want to search for in the Find text box. If the term is located on the current tab, the term is highlighted in the storage array profile information. NOTE: The search is limited to the current tab.
Page 238: Viewing The Logical Associations
Viewing the Logical Associations You can use the Associated Logical Elements option to view the logical associations among different virtual disks in a storage array. To view the associations for source virtual disks, snapshot virtual disks, and snapshot repository virtual disks: 1 In the AMW, select the Logical tab or in the Topology pane of the Mappings tab.
Page 239: Finding Nodes
Finding Nodes You can use the Find option to search for a particular node on the Logical tab, the Physical tab, or the Mappings tab of the AMW. The search may be based on a particular node name, the RAID level, virtual disk capacity, or specific free capacity nodes.
Page 240: Using Go To
6 To search for all nodes based on their virtual disk capacity, perform these steps: Select Find all virtual disks with capacity. Type the capacity in the GB box. Specify that the capacity to be matched is less than, equal to, or greater than the capacity entered in the GB box.
Page 241: Recovering From An Unresponsive Storage Array Condition
1 On the Logical tab of the AMW, select one of these virtual disks, and go to the indicated step: • Snapshot virtual disk—Go to step 2. • Snapshot repository virtual disk—Go to step 3. • Source virtual disk—Go to step 4. •...
Page 242 To recover from an unresponsive storage array: 1 Check the Tree View in the EMW to see if all storage arrays are unresponsive. 2 If any storage arrays are unresponsive, check the storage management station network connection to make sure that it can reach the network. 3 Ensure that the RAID controller modules are installed and that there is power to the storage array.
Page 243 12 For an in-band managed storage array, make sure that the host is network accessible by using the ping command to verify that the host can be reached. Type one of these commands, and press <Enter>. • ping <host-name> • ping <RAID controller module-IP-address>...
Page 244: Locating A Physical Disk
22 Determine if there is an excessive amount of network traffic to one or more RAID controller modules. This problem is self-correcting because the EMW software periodically retries to establish communication with the RAID controller modules in the storage array. If the storage array was unresponsive and a subsequent try to connect to the storage array succeeds, the storage array becomes responsive.
Page 245: Locating An Expansion Enclosure
4 When you have located the physical disks, click OK. The LEDs stop blinking. If any other blink operations (Blink Disk Group, Blink Storage Array, Blink Physical Disk Ports, or Blink Expansion Enclosure) are currently being invoked from another storage management station, these LEDs also stop blinking.

Blink Physical Disk) are currently being invoked from another storage management station, these LEDs also stop blinking. 5 In the rare case that the LEDs on the expansion enclosure do not stop blinking, from the AMW, select Storage Array Blink Stop All Indications.
Page 247: Smrepassist Utility
You can also use this utility to resolve duplicate signature problems for snapshot virtual disks. From a command prompt window on a host running Windows, navigate to: C:\Program Files\Dell\MD Storage Manager\util and run the following command: SMrepassist -f <filesystem-identifier> where -f flushes all the memory-resident data for the file system indicated by <filesystem-identifier>, and <filesystem-identifier>...
Page 248: Unidentified Devices
Unidentified Devices An unidentified node or device occurs when MDSM cannot access a new storage array. Causes for this error include network connection problems, the storage array is turned off, or the storage array does not exist. NOTE: Before beginning any recovery procedure, make sure that the host context agent software is installed and running.
Page 249 Make sure that the network can access the host by using the ping command in the following syntax: ping <host-name-or-IP-address-of-the-host>. If the network can access the host, continue to step c. If the network cannot access the host, go to step d. Remove the host with the unresponsive status from the MDSM, and add that host again.
Page 250 If this problem exists, see support.dell.com. 6 Look to see if there is too much network traffic to one or more controllers. This problem corrects itself because the MDSM tries to re-establish communication with the controllers in the storage array at regular times.
