Blink and Unblink (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 may want to use this task to
locate a failed disk.
On most controllers, the Blink task automatically cancels after a short duration such as 30 or 60 seconds. If you need to cancel the Blink task or if the physical
disk continues to blink indefinitely, use the Unblink task.
Remove Dead Segments
Does my controller support this feature? See "Supported Features."
The Remove Dead Segments task recovers disk space that is currently unusable. A dead or orphaned disk segment refers to an area of a physical disk that is
unusable for any of the following reasons:
l The dead segment is an area of the physical disk that is damaged.
l The dead segment is included in a virtual disk, but the virtual disk is no longer using this area of the physical disk.
l The physical disk contains more than one virtual disk. In this case, disk space that is not included in one of the virtual disks may be unusable.
l The dead segment resides on a physical disk that has been disconnected from and then reconnected to the controller.
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. If no tasks can be performed because of controller or system configuration limitations, then the Tasks drop-down
menu displays No Task Available.
NOTE: The Blink and Unblink tasks are only supported for hotswap physical disks (disks that reside in a carrier). When using an Ultra SCSI, Ultra2 SCSI,
Ultra160 SCSI, LSI 1020, LSI 1030, or LSI PCI-e 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.
