Set Background Initialization Rate
Does my controller support this feature? See "Supported Features."
The Set Background Initialization Rate task changes the amount of system resources dedicated to the background initialization task. See "Background
Initialization on PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di Controllers" for more information on the background initialization task.
The background initialization rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated to running the
background initialization task. At 0%, the background initialization will have the lowest priority for the controller, will take the most time to complete, and will
be the setting with the least impact to system performance. A background initialization rate of 0% does not mean that the background initialization is stopped
or paused.
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.
Capable Speed
This property displays the highest possible speed with which the device can transfer data.
Manufacture Day
This property displays the day of the month on which the physical disk was manufactured.
Manufacture
Week
This property displays the week of the year during which the physical disk was manufactured.
Manufacture
Year
This property displays the year in which the physical disk was manufactured.
SAS Address
This property displays the SAS address of the physical disk. The SAS address is unique to each SAS disk.
After Import
Status
This property displays what the status of the physical disk would be after the foreign configuration has been imported. Possible values
are:
l Foreign
l Online
l Offline
l Replaced
l Rebuild
