This recommendation applies whenever you make changes to your configuration.Performance Affected after Upgrading to Second Generation FirmwareAfter upgrading to second generation firmware, you may experience a temporary performance impact. This impact is caused by the second generation firmware, which adds smart-battery functionality to the MD3000. In order to accurately measure battery parameters, the batteries are taken through a “learn cycle” and the system’s write cache is disabled for the duration of the learn cycle. The first learn cycle starts soon after the firmware upgrade is completed and takes around 15 hours to complete. During this time, you may experience a temporary performance slowdown for certain kinds of file operations as the write cache is disabled. Once the learn cycle is complete, the write cache is automatically enabled.Future learn cycles are scheduled for every 13 weeks. Y ou can adjust the day and time of the day of future learn cycles using MD Storage Manager (click Tools and select Change Battery Settings).Information Update5Virtual Disk Copy Operation on SATA DisksA virtual disk copy operation may take much longer when a new copy is created on SATA disks. To improve the performance, first create the virtual disk. After the virtual disk is initialized, start the virtual disk copy operation. Load Balancing in Microsoft Windows Server 2008Load balancing in Microsoft® Windows Server® 2008 is provided by the MPIO driver under the MPIO tab. For information about accessing the MPIO tab, see the Installation Guide at /manuals. The following options are supported by MD3000:•Least Path Weight•Least Queue DepthInstalling Linux Operating SystemDuring a Linux operating system installation, the installer lists all the volumes that are discovered from MD3000, including virtual disks that are mapped to the host and Universal Xport. If the operating system needs to be installed on an MD3000 virtual disk, you must ensure that you select the appropriate virtual disk. The array does not respond if you select the Universal Xport disk(s) for installation.Battery Learn CycleIn second generation firmware systems, the cache offload battery undergoes a learn cycle once in every 13 weeks to ensure that the battery is in a good state. The learn cycle performs a complete discharge of the battery followed by a complete recharge. During this cycle, the system cache is disabled on all virtual disks in the system. There may be a temporary impact on the performance of the system when the battery undergoes a learn cycle. A learn cycle takes place under the following situations:•First time upgrade from first generation firmware to second generation firmware•Once in every 13 weeks6Information UpdateThe next scheduled learn cycle can be seen under Tools→Change Battery Settings in the MD Storage Manager. The learn cycle can be postponed by up to seven days at a time through the GUI. Y ou can also use the following SMcli command to postpone a learn cycle: set storageArray learnCycleDate daysToNextLearnCycle=[x]For more information, see the Command Line Interface Guide at /manuals.Creating Host to Virtual Disk MappingsY ou can create Host-to-Virtual Disk mappings to a host group or to a single host. If you have created the mapping to a host that is part of a host group, the mapped host alone will have access to the virtual disk. Additional Disk Group and Virtual Disk Expansion InformationTo expand disks groups or virtual disks, you can use the MD Storage Manager or the command line interface. It is only possible to add one disk at a time or two in the case of RAID10 to expand the disk group.To expand the virtual disk using the command line interface, type: set virtualDisk [VDname] addCapacity=sizetobeaddedFor more information, see the Command Line Interface Guide at /manuals.During disk group and virtual disk expansion operations, you have complete access to the virtual disks and disk group redundancy is maintained at all times. The impact on the performance is minimal during the operation.For more information, see the User's Guide at /manuals.Information Update7Storage Manager for SANsUnable to Assign LUNs to Windows 2008 ServerThe Windows Server 2008 Storage Manager for SANs utility can be used to create and manage virtual disks in the MD3000 from the host server. If the host server contains SAS 5/i HBAs, the SAS 5/i ports must be disabled in the Storage Manager for SANs utility to prevent issues with assigning virtual disks (LUNs) to the host server.Perform the following steps:1Click LUN Management.2Click Manage Server Connection.3Select the host server.4In the Fiber Channel Ports tab, disable all the SAS 5/i ports and leave the SAS5/e ports enabled.There are 8 SAS 5/i ports per SAS 5/i HBA in the host server. The HBA Port WWN has the following format: xx:xx:xx:xx:xx:xx:xx:00 toxx:xx:xx:xx:xx:xx:xx:07.NOTE: SAS 5/e HBAs have two ports with HBA Port WWN as follows:yy:yy:yy:yy:yy:yy:yy:00 and yy:yy:yy:yy:yy:yy:yy:04Array Password Reset Using Microsoft Windows Server 2008To reset a lost or forgotten password on an MD3000 array, a command must be issued via the serial port on either controller in the array to clear the existing password. This task is accomplished through COM port connection from a server, workstation or laptop to a controller on the MD3000 array.On most Windows operating systems, the HyperTerminal application is used to establish the COM port connection to the serial port on the controller. However, HyperTerminal is not available on Windows Server 2008 systems.8Information UpdateComplete the following steps to reset the password to an MD3000 array if your system is running the Windows Server 2008 operating system:1Obtain a terminal application capable of COM port connections.2Configure the application to use the communication settings as described on page 23 of the Dell PowerVault Modular Disk Storage Manager User’s Guide.3Proceed with the password reset procedure described on page 24 of the User’s Guide.Modular Disk Storage ManagerThe following updates apply to the Modular Disk Storage Manager(MD Storage Manager):•When the MD Storage Manager is installed on Red Hat® Enterprise Linux® systems or SUSE® Linux Enterprise Servers, or when theMD Storage Manager is running on SUSE Linux Enterprise Servers,Japanese and Simplified Chinese are not supported.Physical Disk MigrationCold power-up migration of physical disk s from one MD3000 duplex configuration to another MD3000 duplex configuration is supported only when all physical disk s are moved from one system to another. No other migrations, including partial physical disk migration and RAID controller module migration, are supported.RAID LevelChange Disk Group RAID LevelFollow these instructions to change the RAID level of a disk group as needed: 1In MD Storage Manager, click the Modify tab and click Change Disk Group RAID Level.2Select the disk group that you want to modify.3Select the new RAID level from the drop-down menu.4Click Change to start the process.Information Update910Information UpdateNOTE: Dell recommends backing up the disk group before modifying the RAIDlevel.NOTE: The number of disks in the disk group should meet its RAID level criteria. RAID1 and RAID10 require an even number of disks. On the MD3000, RAID 5requires a minimum of 3disks and RAID 6 requires a minimum of 5 disks. You may need to add free capacity to the disk group before changing the RAID level.RAID Level Migration RequirementsSuccessful RAID Level Migration (RLM) requires that the appropriate number of physical disk s are present in your disk group. To perform RLM from a RAID 1 or RAID 10 to an odd-number of physical disks (five or more) in RAID 5, first add an even number of disks to the RAID 1 or RAID 10, convert to RAID 5, then add another physical disk to make the count odd.Under-Reported Disk CapacityThe unit Gigabyte (GB) is often used to refer to calculation of both 109bytes and 230 bytes. The MD Storage Manager calculates hard disk capacity in GB using 230 bytes as compared to 109 that is used by hard disk manufacturers, and therefore displays a smaller capacity than reported by the hard drive vendor. There is no actual loss of available data capacity, and the MD3000 only reserves 512 MB (106) of space per hard disk for meta-data usage.Configuration File Write ErrorUsing the MD Storage Manager with Microsoft Windows Server 2008 or Microsoft Windows Vista can result in a Configuration File Write Error . The MD Storage Manager will be unable to save any changes to the configuration files. This error is seen when the application is run as a user without Local Administrator privileges. MD Storage Manager requires Local Administrator privileges for full functionality.Workaround: This error can be bypassed by running the MD StorageManager with local administrator privileges. This can be set by right-clicking the shortcut and clicking Run as Administrator . This setting can be made permanent by modifying the shortcut properties and enabling Always run as administrator .Limitations of NTFS-Formatted DisksThe following error may occur when formatting virtual disks larger than 2TB using the NTFS protocol:The format operation did not complete because the cluster count is higher than expected.This error is caused by the limitations of NTFS-formatted disks based on cluster size.Table 1-1.Limitations of NTFS-Formatted Disks Based on Cluster SizeCluster size Maximum NTFS Volume Size (bytes RAW)5122,199,023,255,040 (2TB)1,0244,398,046,510,080 (4TB)2,0488,796,093,020,160 (8TB)4,09617,592,186,040,320 (16TB)8,19235,184,372,080,640 (32TB)16,38470,368,744,161,280 (64TB)32,768140,737,488,322,560 (128TB)65,536281,474,976,645,120 (256TB)As seen in T able1-1, you will need to modify cluster size to format certain virtual disks. T o expand existing virtual disks beyond the limits, back up the data on any existing virtual disks and reformat the virtual disk with the new cluster size. Please refer to Microsoft KB302873 and KB814594 for additional information.
