You should be familiar with the size requirements and other considerations associated with hot spares. See the following sections for more information:

l "Protecting Your Virtual Disk with a Hot Spare"

l "Considerations for Hot Spares on PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, CERC ATA100/4ch, PERC 5/E, PERC 5/i, PERC 6/E, PERC

6/I, and CERC 6/I Controllers"

l "Considerations for Hot Spares on PERC 3/Si, 3/Di, CERC SATA1.5/6ch, S100, and S300 Controllers"

l "Global Hot Spare Considerations on a SAS 6/iR"

Online and Offline



Does my controller support this feature? See "Supported Features."

The Online and Offline tasks only apply to physical disks that are included in a redundant virtual disk and attached to a PERC 3/SC, 3/DC, 3/QC,4/SC, 4/DC,

4e/Si, 4e/Di, 4e/DC, 4/Di, or CERC ATA100/4ch controller.

Use the Offline task to deactivate a disk before removing it. Use the Online task to reactivate an offline disk. In some cases, you may want to use the Online

task on a failed disk in an attempt to recover data from the disk. See "Using the Physical Disk Online Command on Select Controllers" for more information.



To online or offline the physical disk:



1. Review the physical disk that will be made online or offline. When making a physical disk offline, be aware that there can be data loss. Back up your

data, if necessary. If you want to blink the physical disk, click the Blink button.



2. Click Online or Offline when ready or click Go Back to Previous Page.



To locate this task in Storage Management:



1. Expand the Storage tree object to display the controller objects.



2. Expand a controller object.



3. Expand a Connector object.



4. Expand the enclosure or Backplane object.



5. Select the Physical Disks object.



6. Select Online or Offline from the Available Tasks drop-down menu of the physical disk you want to make online or offline.



7. Click Execute.

Clear Physical Disk and Cancel Clear



Does my controller support this feature? See "Supported Features."

Use the clear physical disk task to erase data residing on a physical disk. The Clear task applies to physical disks that are in Ready state and that contain data

or that are in Clear state.



NOTE: When deleting virtual disks, all assigned global hot spares may be automatically unassigned when the last virtual disk associated with the

controller is deleted.

CAUTION: The SAS 6/iR controller enables you to assign two physical disks as global hot spare. Assigning a physical disk as a global hot spare on

a SAS 6/iR controller is likely to cause data loss from the physical disk. If the system or boot partition resides on the physical disks, it may be

destroyed. You should only assign physical disks that do not contain critical data. For more information about global hot spares and the SAS 6/iR,

see "Global Hot Spare Considerations on a SAS 6/iR."

NOTE: The Online and Offline tasks are not supported on the PERC 4/IM controller or the PERC 3/Si, 3/Di, CERC SATA1.5/6ch, and CERC SATA1.5/2s

controllers.

NOTE: A physical disk may display the Clear state if it is a member of a virtual disk that is being slow initialized. Performing a Cancel Clear task on the

physical disk causes the Slow Initialize task to be cancelled for the entire virtual disk. See "Format and Initialize; Slow and Fast Initialize" and

"Considerations for Slow Initialize" for more information.
