78 Management Applications for PERC Cards
Physical Disk Actions
Table 5-6 describes the actions you can perform on physical disks.
For procedures that can be used to perform the actions, see "Physical Disk
Management" on page 81.
Rebuild
Select Rebuild to rebuild one or more failed physical disks. For information
on performing a physical disk rebuild, see "Performing a Manual Rebuild of an
Individual Physical Disk" on page 85.
Several of the controller configuration settings and the virtual disk settings
affect the actual rate of rebuild. The factors include the rebuild rate setting,
virtual disk stripe size, virtual disk read policy, virtual disk write policy, and the
amount of workload placed on the storage subsystem. For information on
getting the best rebuild performance from your RAID controller, see the
documentation at support.dell.com/manuals.
Table 5-6. Physical Disk Actions
Action Description
Rebuild Regenerates all data to a replacement disk in a redundant
virtual disk (RAID level 1, 5, 6, 10, 50, or 60) after a disk
failure. A disk rebuild normally occurs without interrupting
normal operations on the affected virtual disk.
Replace Member Replaces the disk in the virtual disk with another disk that can
be selected.
LED Blinking Indicates when physical disks are being used to create a virtual
disk. You can choose to start or stop the LED blinking.
Force Online Changes the state of the selected physical disk to online.
Force Offline Changes the state of the selected physical disk so that it is no
longer part of a virtual disk.
Make Global HS Designates the selected physical disk as a global hot spare.
A global hot spare is part of a pool for all virtual disks
controlled by the controller.
Designates the selected physical disk as a global hot spare.
Remove HS Removes a dedicated hot spare from its disk group or a global
hot spare from the global pool of hot spares.
