Property Definition Enable Global Hot Spare Enables the Global Hot Spare Protection Policy. Minimum Number of Disks Displays the minimum number of physical disks to be assigned as global hot spares for the controller. Severity Level Displays the severity level that you must assign to the generated alert, if the Global Hot Spare policy is violated.
l Considerations for RAID 10, RAID 50, and RAID 60—If you have created a RAID 10 or RAID 50 virtual disk that does not fully consume its member physical disks, then you cannot assign a dedicated hot spare to the RAID 10 or RAID 50 virtual disk. Storage Management does not allow you to create RAID 10 and RAID 50 virtual disks from partial physical disks. You therefore do not encounter this situation if you use Storage Management to create your virtual disks.
To ensure that the controller firmware always has a healthy physical disk as a global hot spare, do the following: l When removing a physical disk that is assigned as a global hot spare, unassign the hot spare before removal and reassign another physical disk as the global hot spare. l Immediately replace any physical disk that has failed or been removed. This ensures that a healthy disk resides in a slot that the controller firmware assumes is a hot spare.

Back to Contents Page Understanding RAID Concepts Dell OpenManage Server Administrator Storage Management User's Guide What Is RAID? Organizing Data Storage for Availability and Performance Choosing RAID Levels and Concatenation Comparing RAID Level and Concatenation Performance No-RAID Storage Management uses Redundant Array of Independent Disks (RAID) technology to provide Storage Management capability.
RAID provides different methods or RAID levels for organizing the disk storage. Some RAID levels maintain redundant data so that you can restore data after a disk failure. Different RAID levels may also entail an increase or decrease in the system's I/O (read and write) performance. Maintaining redundant data requires the use of additional physical disks. As more disks become involved, the likelihood of a disk failure increases.
l Concatenates n disks as one large virtual disk with a capacity of n disks. l Data fills up the first disk before it is written to the second disk. l No redundancy data is kept. When a disk fails, the large virtual disk fails. l No performance gain. l No redundancy.
l Number of Physical Disks per Virtual Disk l Maximum Number of Virtual Disks per Controller RAID Level 1 (Mirroring) RAID 1 is the simplest form of maintaining redundant data. In RAID 1, data is mirrored or duplicated on one or more physical disks. If a physical disk on one side of the mirror fails, then the data can be rebuilt using the physical disk on the other side of the mirror. Figure 3-3.
RAID 5 Characteristics: l Groups n disks as one large virtual disk with a capacity of (n-1) disks. l Redundant information (parity) is alternately stored on all disks. l When a disk fails, the virtual disk still works, but it is operating in a degraded state. The data is reconstructed from the surviving disks. l Better read performance, but slower write performance. l Redundancy for protection of data.
l The virtual disk remains functional with up to two disk failures. The data is reconstructed from the surviving disks. l Better read performance, but slower write performance. l Increased redundancy for protection of data. l Two disks per span are required for parity. RAID 6 is more expensive in terms of disk space.
l Number of Physical Disks per Virtual Disk l Maximum Number of Virtual Disks per Controller RAID Level 60 (Striping over RAID 6 sets) RAID 60 is striping over more than one span of physical disks that are configured as a RAID 6. For example, a RAID 6 disk group that is implemented with four physical disks and then continues on with a disk group of four more physical disks would be a RAID 60. Figure 3-7.
RAID 10 Characteristics: l Groups n disks as one large virtual disk with a capacity of (n/2) disks, where n is an even integer. l Mirror images of the data are striped across sets of physical disks. This level provides redundancy through mirroring. l When a disk fails, the virtual disk still works. The data is read from the surviving mirrored disk. l Improved read performance and write performance. l Redundancy for protection of data.

Common Troubleshooting Procedures This section describes commands and procedures that can be used in troubleshooting.
On SCSI controllers, use the Rescan controller task to update information for the controller and attached devices. This operation may take a few minutes if there are a number of devices attached to the controller. If the Rescan does not properly update the disk information, you may need to reboot your system.
Does my controller support this feature? See Supported Features If you do not have a suitable backup available, and if the failed disk is part of a virtual disk on a controller that supports the Online physical disk task, then you can attempt to retrieve data by selecting Online from the failed disk's drop-down task menu. The Online command attempts to force the failed disk back into a Online state. If you are able to force the disk into a Online state, you may be able to recover individual files.
l Virtual Disk Errors on Linux l Problems Associated With Using the Same Physical Disks for Both Redundant and Non-Redundant Virtual Disks A Rebuild Does Not Work A rebuild does not work in the following situations: l The virtual disk is non-redundant—For example, a RAID 0 virtual disk cannot be rebuilt because RAID 0 does not provide data redundancy.
A Virtual Disk of Minimum Size is Not Visible to Windows Disk Management If you create a virtual disk using the minimum allowable size in Storage Management, the virtual disk may not be visible to Windows Disk Management even after initialization. This occurs because Windows Disk Management is only able to recognize extremely small virtual disks if they are dynamic. It is generally advisable to create virtual disks of larger size when using Storage Management.

Virtual Disk Considerations for PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, PERC 5/E, PERC 5/i, PERC 6/E, and PERC 6/I Controllers In addition to the considerations described in this section, you should also be aware of the controller limitations described in Number of Physical Disks per Virtual Disk.
On some versions of the Linux operating system, the virtual disk size is limited to 1TB. Before creating a virtual disk that is larger than 1TB, you should make sure that your operating system supports this virtual disk size. The support provided by your operating system depends on the version of the operating system and any updates or modifications that you have implemented. In addition, you should investigate the capacity of your peripheral devices to support a virtual disk that is larger than 1TB.
Storage Management provides wizards to help you create a virtual disk: l The Create Virtual Disk Express Wizard calculates an appropriate virtual disk layout based on the available space and controller considerations. Using the Express Wizard, you can quickly create a virtual disk using recommended selections. For more information, see Create Virtual Disk Express Wizard (Step 1 of 2). l The Create Virtual Disk Advanced Wizard allows you to specify the read, write, and cache policy for the virtual disk.
CERC SATA1.5/2s N/A N/A N/A PERC 6/E, PERC 6/I, CERC 6/I, PERC H800 Adapter, PERC H700 Adapter, PERC H700 Integrated, and PERC H700 Modular RAID 0 RAID 1 Add a single disk RAID 0 RAID 0, RAID 5 Add at least one additional disk. RAID 0 RAID 6 RAID 6 requires a minimum of 4 disks. Reconfiguration from RAID 0 to RAID 6 requires at least 2 additional disks even when this exceeds the 4-disk minimum required by RAID 6.
What is a Virtual Disk Bad Block? Virtual disk bad blocks are due to bad blocks on one or more member physical disks. Read operation on the virtual disks having bad blocks may fail. Storage Management generates a critical alert (2387) to notify you of the bad blocks on the virtual disk. Virtual disk bad blocks are discovered when the controller performs any operation that requires scanning the disk.
Virtual Disk Properties The virtual disk properties can vary depending on the model of the controller. Virtual disk properties may include: Table 10-3. Virtual Disk Properties Property Definition Status These icons represent the severity or health of the storage component. Normal/OK Warning/Non-critical Critical/Fatal For more information, see Storage Component Severity. Name This property displays the virtual disk name.
SAS—Serial Attached SCSI SATA—Serial Advanced Technology Attachment (SATA) Media This property displays the media type of the physical disks present in the virtual disk. The possible values are: HDD—Hard Disk Drive. A HDD is a non-volatile storage device which stores digitally-encoded data on rapidly rotating platters with magnetic surfaces. SSD—Solid State Drive. An SSD is a data storage device that uses solid-state memory to store persistent data.
l Clear Virtual Disk Bad Blocks l Encrypt Virtual Disk Reconfigure Does my controller support this feature? See Supported Features. Use the Reconfigure task to change the virtual disks properties. For example, you can use this task to add physical disks or change the RAID level. For more information, see Virtual Disk Task: Reconfigure (Step 1 of 3). Format, Initialize, Slow and Fast Initialize Does my controller support this feature? See Supported Features.
Assign and Unassign Dedicated Hot Spare Does my controller support this feature? See Supported Features. Use the Assign Dedicated Hot Spare task to assign a disk as a backup for a single virtual disk. For more information, see Assign and Unassign Dedicated Hot Spare. Check Consistency Does my controller support this feature? See Supported Features. Use the Check Consistency task to verify the accuracy of the redundant (parity) information. This task only applies to redundant virtual disks.
Use the Rename task to change the virtual disk's name. For more information, see Virtual Disk Task: Rename. NOTE: On the CERC SATA1.5/2s controller, you cannot change the default name of a concatenated virtual disk. NOTE: Renaming a virtual disk generates alert 2159. On the CERC SATA1.5/6ch and CERC SATA1.5/2s controllers, alert 2159 displays the new virtual disk name. On the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4/IM, 4e/Si, and 4e/Di controllers, alert 2159 displays the original virtual disk name.
To Create a Virtual Disk Express Wizard: Step 1 of 2 1. 2. Click the radio button to select the correct RAID level. ¡ Depending on the controller, Concatenated enables you to combine the storage capacity of several disks or to create a virtual disk using only a single physical disk. For information on whether the controller supports a single physical disk or two or more when using Concatenated, see Number of Physical Disks per Virtual Disk.
Do the following: 1. Review the virtual disk attributes displayed in the Summary of Virtual Disk Attributes and the Selected Physical Disks sections of the screen. These sections display the selections you made using Create Virtual Disk Express Wizard (Step 1 of 2) and the physical disks that the Express Wizard selected. If you need to change a selection, click Go Back To Previous Page to return to Create Virtual Disk Express Wizard (Step 1 of 2).
Spans are not displayed on this screen. Select Continue to view the span grouping on the Summary screen (Create Virtual Disk Advanced Wizard (Step 4 of 4).) Storage Management calculates the optimum span composition in the following manner: ¡ Determining span calculation: - Calculating the number of disks that can be utilized from the selected disks.
NOTE: If you have selected the Create Encrypted Virtual Disk check box in Create Virtual Disk Advanced Wizard (Step 1 of 4), then only encrypted physical disks are displayed. Else, both encrypted as well as unencrypted physical disks are displayed. The following is an example of what might be displayed: Connector 0 The Connector section of the screen displays the controller's connectors and the disks attached to each connector. Select the disks to be included in the virtual disk.
It is recommended that you specify a unique name for each virtual disk. If you have virtual disks with the same name, it is hard to differentiate the alerts generated for these virtual disks. NOTE: The CERC SATA1.5/2s controller does not allow you to specify a name for concatenated virtual disks. The concatenated virtual disk is created with a default name. 2. The Size text box displays the default size of the virtual disk, depending upon the RAID configuration you selected.
Span Edit In the edit mode, you cannot alter the number of physical disks per span. If there are enough available physical disks, you can reduce or increase the number of spans. You can also alter the contents of a span by removing that span and selecting a new physical disk to comprise that span. To successfully create a virtual disk, a minimum of two spans must exist at all times. NOTE: If you click Span Edit, Intelligent Mirroring that is already been applied becomes invalid.
Does my controller support this feature? See Supported Features. This screen enables you to select the RAID level and size for the reconfigured virtual disk. If you clicked Expand Capacity in the previous step, this screen allows you to expand the capacity of the virtual disk. The Expand Capacity option appears only for PERC H700 and PERC H800 controllers with firmware 7.1 or above. To Reconfigure a Virtual Disk (Changing the RAID Level and Size): Step 2 of 3 1. 2.
Considerations for Concatenated to RAID 1 Reconfiguration on CERC SATA1.5/6ch Controllers When reconfiguring a concatenated virtual disk to a RAID 1 on a CERC SATA1.5/6ch controller, the reconfigured virtual disk may display the Resynching state. When reconfiguring from a concatenated virtual disk to a RAID 1, data is copied from the single concatenated disk to the RAID 1 mirror. The controller perceives this operation as similar to resynching a mirror, and therefore may display the Resynching state.
Formatting or Initializing a Disk To format or initialize a disk: 1. 2. Review the virtual disk that is destroyed by the Format or Initialize and make sure that vital data is not lost. Click Blink at the bottom of the screen to blink the physical disks included in the virtual disk.
3. Select the Virtual Disks object. 4. Select Delete from the Available Tasks drop-down menu. 5. Click Execute. Virtual Disk Task: Rename Does my controller support this feature?

1. Expand the Storage tree object to display the controller objects. 2. Expand a controller object. 3. Select the Virtual Disks object. 4. Select Change Policy from the Available Tasks drop-down menu. 5. Click Execute. Split Mirror Does my controller support this feature? See Supported Features. Use the Split Mirror task to separate mirrored data originally configured as a RAID 1, RAID 1-concatenated, or RAID 10 virtual disk.
NOTE: The Unmirror task is not supported on the CERC SATA1.5/2s controller. NOTE: On the CERC SATA1.5/6ch controllers, doing an Unmirror on a RAID 1-concatenated virtual disk results in a concatenated virtual disk that cannot be subjected to any further modification. You cannot reconfigure or add disks to the resulting concatenated virtual disk. If you do an Unmirror on a RAID 1 virtual disk, the resulting concatenated virtual disk can be reconfigured back to a RAID 1 virtual disk.
To locate this task in Storage Management: 1. Expand the Storage tree object to display the controller objects. 2. Expand a controller object. 3. Select the Virtual Disks object. 4.
