Determining Your Firmware Version

To determine if your software is first generation or second generation, perform the following steps:
1
Connect to the system using the Dell™ PowerVault™ MD Storage Manager.
2
Select the
3
Click Note the firmware version:
If it is 06.xx.xx.xx, it is first generation. If it is 07.xx.xx.xx, it is second generation.

tab.
.

Important Information Before Upgrading Your Firmware

Prior to performing the firmware upgrade, perform a complete backup of the data, and use the Gather Support Information tool to save the system configuration. This recommendation applies whenever you make changes to your configuration.

Performance Affected after Upgrading to Second Generation Firmware

After 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. You can adjust the day and time of the day of future learn cycles using MD Storage Manager (click To ol s and select Change Battery Settings).
Information Update 5

Virtual Disk Copy Operation on SATA Disks

A 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 2008

Load 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 support.dell.com/manuals. The following options are supported by MD3000:
Least Path Weight
Least Queue Depth

Installing Linux Operating System

During 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 Cycle

In 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 weeks
6 Information Update
The next scheduled learn cycle can be seen under To ol sChange Battery Settings in the MD Storage Manager. The learn cycle can be postponed by up
to seven days at a time through the GUI. You 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 support.dell.com/manuals.

Creating Host to Virtual Disk Mappings

You 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 Information

To 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=sizetobeadded
For more information, see the Command Line Interface Guide at support.dell.com/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 support.dell.com/manuals.
Information Update 7

Storage Manager for SANs

Unable to Assign LUNs to Windows 2008 Server

The 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:
1

Array Password Reset Using Microsoft Windows Server 2008

To 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.
8 Information Update
Complete the following steps to reset the password to an MD3000 array if your system is running the Windows Server 2008 operating system:
1
Obtain a terminal application capable of COM port connections.
2
Configure the application to use the communication settings as described on page 23 of the
Guide
.

Change Disk
NOTE: Dell recommends backing up the disk group before modifying the
RAID level.
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 5 requires a minimum of 3 disks 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 Requirements

Successful RAID Level Migration (RLM) requires that the appropriate number of 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 Capacity

The unit Gigabyte (GB) is often used to refer to calculation of both 109bytes
30
and 2 using 2 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 (10
bytes. The MD Storage Manager calculates hard disk capacity in GB

) of space per hard disk for meta-data usage.

Configuration File Write Error

Using 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 Storage Manager 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.
10 Information Update

Limitations of NTFS-Formatted Disks

The 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 Size
Cluster size Maximum NTFS Volume Size (bytes RAW)
512 2,199,023,255,040 (2TB)
1,024 4,398,046,510,080 (4TB)
2,048 8,796,093,020,160 (8TB)
4,096 17,592,186,040,320 (16TB)
8,192 35,184,372,080,640 (32TB)
16,384 70,368,744,161,280 (64TB)
32,768 140,737,488,322,560 (128TB)
65,536 281,474,976,645,120 (256TB)
As seen in Table 1-1, you will need to modify cluster size to format certain virtual disks. To 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.

Password Reset Procedure

The password reset procedure differs slightly between the first generation and second generation controllers. Please see the latest version of the Dell PowerVault MD3000 RAID Controller Password Reset on support.dell.com for details on the password reset procedures.
