NOTE: Different controllers support different features. For this reason, the tasks displayed on the tasks drop-down
menu can vary depending on which controller is selected in the tree view. No Task Available is the only option in the
drop-down list box when no tasks can be performed because of controller or system configuration limitations.
Physical Disk Tasks
The following are the list of tasks that you can perform on a physical disk:
● Blinking And Unblinking A Physical Disk
●
Removing Dead Segments
● Assigning And Unassigning Global Hot Spare
● Preparing To Remove
● Setting Online And Offline
● Rebuilding Data
● Cancelling A Rebuild
● Performing A Clear Physical Disk And Cancel Clear
● Enabling Revertible Hot Spare
● Performing Cryptographic Erase
● Convert To RAID Capable Disk
● Convert To Non-RAID Disk
Blinking And Unblinking A Physical Disk
Does my controller support this feature? See Supported Features.
The Blink task allows you to find a disk within an enclosure by blinking one of the light-emitting diodes (LEDs) on the disk. You
can use this task to locate a failed disk.
On most controllers, the Blink task cancels once you select Unblink. Select Unblink to cancel the Blink task or to stop the
LED on the physical device that is blinking indefinitely.
NOTE:
The Blink and Unblink tasks are only supported for hotswap physical disks (disks that reside in a carrier). When
using an Broadcom PCIe U320 controller, the Blink and Unblink tasks apply to physical disks contained in carriers that
can be inserted into a server or an enclosure. If the physical disk is not contained in a carrier but is instead designed to be
connected with a SCSI cable (typically a ribbon cable), then the Blink and Unblink tasks are disabled.
Removing Dead Segments
Does my controller support this feature? See Supported Features.
The Remove Dead Segments task recovers disk space that is unusable. A dead or orphaned disk segment refers to an area of
a physical disk or physical device that is unusable for any of the following reasons:
● The dead segment is an area of the physical disk or physical device that is damaged.
● The dead segment is included in a virtual disk, but the virtual disk is no longer using this area of the physical disk or physical
device.
● The physical disk or physical device contains more than one virtual disk. In this case, disk space that is not included in one of
the virtual disks may be unusable.
● The dead segment resides on a physical disk or physical device that has been disconnected and then reconnected to the
controller.
Preparing To Remove
NOTE: Cryptographic Erase is not supported for NVMe devices connected to SWRAID controller.
