User's Manual
Name
This property displays the name of the physical disk. The name is comprised of the connector number followed by the disk number.
Current State
This property displays the current state of the physical disk.
After Import
State
This property displays the after-import state of the physical disk. The physical disk can be imported in any of the following states.
Online — The physical disk will be part of the imported virtual disk and will function normally.
Offline — The physical disk will be offline after import to the virtual disk.
Foreign — The virtual disk containing the physical disk cannot be imported and the physical disk will remain in foreign state.
Rebuild — After import of virtual disk, the physical disk will rebuild.
Replacing — A Replace Member Disk task will be performed on the physical disk. For more information, see "Replace Member Disk" and
"Revertible Hot Spare."
Capacity
This property displays the full capacity of the disk.
Failure
Predicted
This property displays whether or not the physical disk has received a Self-Monitoring Analysis and Reporting Technology (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
For information on Alert Messages, see the Dell OpenManage Server Administrator Messages Reference Guide on the Dell Support website at
support.dell.com/manuals.
NOTE: On replacing a SMART error drive with a good drive on PERC4/IM controllers, it is necessary to perform a rescan operation on the
controller, for Storage Management to display the correct status of the newly inserted drive.
Progress
This property displays the progress of an operation 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.
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 actually
being used. This occurs when the used space is 0.005 GB or less. The algorithm for calculating the used disk space rounds off 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 off 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 Enclosure Management Module (EMM) on the enclosure.
