Dell™OpenManage™ServerAdministratorStorageManagementUser'sGuide
Physical disks reside within an enclosure or are attached to the controller. On a RAID controller, physical disks are used to create virtual disks.
Add a New Disk to Your System
1. Install or attach the new physical disk (or disks). Refer to the documentation that came with the disk for more information.
2. Do one of the following depending on the controller technology. See "RAID Controller Technology: SCSI, SATA, ATA, and SAS" for more information.
For SCSI, SATA, and ATA Controllers
a. Select the controller to which the disk is attached and click the Information/Configuration tab. b. Execute the Rescan task.
The new disk should be displayed in the tree view after the rescan. If the new disk is not displayed, restart the computer.
For SAS Controllers
a. Check the Alert Log for an alert verifying that the system has identified the new disk. You may receive alert "2052" or "2294." b. Refresh the display by clicking Refresh or by changing screens.
The new physical disk should be displayed in the tree view after refreshing the display. If the new disk is not displayed, restart the computer.
Related Information
l See "Replacing a Failed Disk" if you are replacing a disk that is part of a virtual disk. l See "Virtual Disk Considerations for PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, CERC ATA100/4ch, PERC 5/E, PERC 5/i, PERC 6/E, and
PERC 6/I Controllers" or "Virtual Disk Considerations for PERC 3/Si, 3/Di, CERC SATA1.5/6ch, and CERC SATA1.5/2s controllers" if you are intending to
include the new disk in a virtual disk.
How to Avoid Removing the Wrong Disk
You can avoid removing the wrong disk by blinking the LED display on the disk that you intend to remove. See the following sections for information on blinking the LED display:
l See "Blink and Unblink (Physical Disk)" to blink the LED display on a physical disk. l See "Blink and Unblink (Virtual Disk)" to blink the LED display on all physical disks included in a particular virtual disk.
If you have already removed the wrong disk, see "Recovering from Removing the Wrong Physical Disk."
Replacing a Physical Disk Receiving SMART Alerts
SMART alerts are messages predicting that a disk may fail in the near future. If a physical disk is receiving SMART alerts, you should replace the disk. Use the following procedures to replace a disk receiving SMART alerts.

Physical Disk Properties and Tasks
NOTE: Clicking the Refresh button in the right pane refreshes only the right pane. To view the new physical disk in the left pane tree view, click the
system name displayed at the top of the left pane, or select View --> Refresh from the browser's menu bar.
If the disk is part of a redundant virtual disk:
1. Select the redundant virtual disk that includes the physical disk that is receiving SMART alerts and perform the Check Consistency task. See "Check
Consistency" for more information.
2. Select the disk that is receiving SMART alerts and execute the Offline task.
3. Manually remove the disk.
4. Insert a new disk. Make sure that the new disk is the same size or larger as the disk you are replacing. (On some controllers, you may not be able to use the additional disk space if you insert a larger disk. See "Virtual Disk Considerations for PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si,
4e/Di, CERC ATA100/4ch, PERC 5/E, PERC 5/i, PERC 6/E, and PERC 6/I Controllers" for more information.) After you complete this procedure, a rebuild is
automatically initiated because the virtual disk is redundant.
If the disk is not part of a redundant virtual disk:
1. Back up data from the virtual disk.
2. Delete the virtual disk.
3. Replace the disk that is receiving SMART alerts.
4. Create a new virtual disk. Make sure that the new virtual disk is the same size or larger than the original virtual disk. For controller-specific information on creating virtual disks, see "Virtual Disk Considerations for PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, CERC ATA100/4ch, PERC 5/E,
PERC 5/i, PERC 6/E, and PERC 6/I Controllers" and "Virtual Disk Considerations for PERC 3/Si, 3/Di, CERC SATA1.5/6ch, and CERC SATA1.5/2s controllers."
5. Restore the backed up data from the original virtual disk onto the newly created virtual disk.

Physical Disk Properties and Tasks
Use this window to view information about physical disks and execute physical disk tasks.
Physical Disk Properties
The following table describes properties that may be displayed for physical disks depending on the controller.
CAUTION: To avoid potential data loss, you should perform a check consistency before removing a physical disk that is receiving SMART alerts.
The check consistency verifies that all data is accessible within the redundant virtual disk and uses the redundancy to repair any bad blocks that may be present. In some circumstances, failure to perform a check consistency can result in data loss. This may occur, for example, if the physical disk receiving SMART alerts has bad disk blocks and you do not perform a check consistency before removing the disk.
Property
Definition
Status
These icons represent the severity or health of the storage component.
Normal/OK
Warning/Non-critical
Critical/Fatal
See "Storage Component Severity" for more information.
Name
This property displays the name of the physical disk. The name is comprised of the connector number followed by the disk number.
State
This property displays the current state of the physical disk.
Ready — The physical disk is functioning normally. If the disk is attached to a RAID controller, Ready state indicates that the disk is available to be used by a virtual disk. When the physical disk is used in a virtual disk, the state changes to Online.
Online — The physical disk is part of a virtual disk and is functioning normally. See "Online and Offline" for more information.
Degraded — The physical disk has encountered a failure and is operating in a degraded state.
Failed — The physical disk has encountered a failure and is no longer functioning. This state is also displayed when a physical disk that is part of a redundant virtual disk has been taken offline or deactivated. See "Online and Offline" for more information.
Offline — The physical disk has failed or contains dead segments. Check to see whether the "Remove Dead Segments" task appears on the physical disk drop-down menu. If it does, perform a "Rescan Controller" and then do a "Remove Dead Segments" for the physical disk. If the "Remove Dead Segments" task is not displayed, then the physical disk cannot be recovered. See "Considerations for PERC 3/Si, 3/Di, CERC
SATA1.5/6ch, and CERC SATA1.5/2s Controllers When Physical Disks are Shared by Redundant and Nonredundant Virtual Disks" for related
information.
On the PERC 5/E controller, the Offline state indicates that the disk is included in a virtual disk, but it is not receiving I/O. This may occur when a user has set the disk to Offline. See "Online and Offline" for more information.
Rebuilding — Data from a redundant virtual disk is currently being rebuilt onto the physical disk.
Incompatible — The physical disk is not suitable for a rebuild. The physical disk may be too small or it may be using an incompatible technology. For example, you cannot rebuild a SAS disk with a SATA disk or a SATA disk with a SAS disk.
Removed — The physical disk has been removed. This state only applies to physical disks that are part of a virtual disk.
Clear — The Clear task is being performed on the physical disk. A physical disk may also display the Clear state if the physical disk is a member of a virtual disk that is being slow initialized. For more information, see "Clear Physical Disk and Cancel Clear" and "Format and
Initialize; Slow and Fast Initialize."
SMART Alert Detected — A SMART alert (predictive failure) has been detected on the physical disk. The physical disk may fail and should be replaced. This state applies to physical disks attached to non-RAID controllers.
Unknown — The physical disk has failed or is in an unusable state. In some cases the physical disk can be returned to a usable state by performing an "Initialize" task. If the "Initialize" task does not appear on the physical disk drop-down menu, then this disk cannot be recovered.
Foreign — The physical disk has been moved from another controller and contains all or some portion of a virtual disk (foreign configuration). A physical disk that has lost communication with the controller due to a power loss, faulty cable or other failure event may also display the Foreign state. See "Foreign Configuration Operations" for more information.
Unsupported — The physical disk is using an unsupported technology. The physical disk cannot be managed by Storage Management.
Replacing — A Replace Member Disk task is being performed on the physical disk. For more information, see "Replace Member Disk" and "Revertible Hot Spare."
NOTE: You can cancel the copying of data at any time during the execution of this task.
Capacity
This property displays the full capacity of the disk.
Failure Predicted
This property displays whether or not the physical disk has received a SMART alert and is therefore predicted to fail. For more information on SMART predictive failure analysis, see "Monitoring Disk Reliability on RAID Controllers." For information on replacing the physical disk, see "Replacing a Physical Disk Receiving SMART Alerts."
You may also want to review the Alert Log to see whether the physical disk has generated alerts pertaining to a SMART predictive failure. These alerts can assist you in identifying the cause of the SMART alert. The following alerts may be generated in response to a SMART alert:
"2094"
"2106"
"2107"
"2108"
"2109"
"2110"
"2111"
Progress
This property displays how close to completion an operation is that is being performed on the physical disk. For example, if the physical disk is being rebuilt, then a value of 52% indicates that the rebuild is 52% complete.
This property is only displayed when an operation is being performed on the physical disk.
Physical Disk Tasks
Do the following to execute a physical disk task:
1. Expand the Storage tree object to display the controller objects.
2. Expand a controller object.
3. Expand a Connector object.
4. Expand the enclosure or Backplane object.
5. Select the Physical Disks object.
6. Select the Information/Configuration subtab.
7. Select a task from the Available Tasks drop-down menu.
8. Click Execute.
Physical Disk Drop-down Menu Tasks:
l "Blink and Unblink (Physical Disk)" l "Remove Dead Segments" l "Assign and Unassign Global Hot Spare"
Bus Protocol
This property displays the technology that the physical disk is using. Possible values are:
SCSI — Small Computer System Interface
SAS — Serial Attached SCSI
SATA — Serial Advanced Technology Attachment (SATA)
Media
This property displays the media type of the physical 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.
Unknown—Storage Management is unable to determine the media type of the physical disk.
Used RAID Disk Space
This property displays how much of the physical disk space is being used by the virtual disks on the controller. This property is Not Applicable for physical disks attached to non-RAID controllers.
In certain circumstances, the Used RAID Disk Space displays a value of zero (0) even though a portion of the physical disk is being used. This occurs when the used space is 0.005 GB or less. The algorithm for calculating the used disk space rounds a figure of 0.005 GB or less to
0. Used disk space that is between 0.006 GB and 0.009 GB is rounded up to 0.01 GB.
Available RAID Disk Space
This property displays the amount of available space on the disk. This property is Not Applicable for physical disks attached to non-RAID controllers.
Hot Spare
This property indicates whether the disk has been assigned as a hot spare. This property is Not Applicable for physical disks attached to non-RAID controllers.
Vendor ID
This property displays the disk's hardware vendor.
Product ID
This property displays the disk's product ID.
Revision
This property displays the disk's revision number.
Serial No.
This property displays the disk's serial number.
Negotiated Speed
This property displays the speed of data transfer that the disk negotiated while spinning up and upon initial communication with the controller. This speed is dependent on the speed of the disk, the capable speed of the controller, the current speed of the controller on that connector, and the speed of the EMM (Enclosure Management Module) on the enclosure.
Capable Speed
