Guidelines To Replace A Physical Disk Or Physical
Device
A replacement disk may not be the same model as the physical disks or devices in the storage enclosure. Use the following guidelines when replacing a disk:
• A drive within an array must be replaced with a drive of equal or greater capacity.
• Consider the bus speed while replacing a drive. Replacing drives with equal or greater bus speeds within the same array is supported.
You can use both 3 GB and 6 GB drives in the same array. However, it is not recommended to replace a 6 GB drive with a 3 GB drive.
Although it is fully functional, the performance could be impacted. Replacing 3 GB drives with 6 GB drives is supported. This occurs more frequently as legacy parts are depleted and warranty service is required.
• Consider the Revolutions Per Minute (RPM) while replacing a drive. Replacing drives with equal or greater spindle speeds within the same array is supported. You can use both 10000 rpm and 15000 rpm drives in the same enclosure. However, it is not recommended to replace a 15000 rpm drive with a 10000 rpm drive. Although it is fully functional, the performance could be impacted. Replacing
10000 rpm drives with 15000 rpm drives is supported. This scenario occurs while replacing parts from service inventory due to part unavailability.
• SAS and SATA drives on the same backplane but not within the same virtual disk.
• Solid-State Drives (SSD) and Hard-Disk Drives (HDD) on the same backplane but not within the same virtual disk.
NOTE: Except for combining SSD, SAS, and SATA drives, only upgrades are supported.
Adding A New Disk To The System
1. Install or attach the new physical disk (or disks) or physical devices. For more information on installing or attaching, see the documentation that came with the disk.
2. Perform the following steps:
For SATA Controllers
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Select the controller to which the disk is attached and click Information/Configuration on the controller Properties page.
3. Select Rescan from the Controller Tasks .
4. Click Execute .
Physical Disks Or Physical Devices 103
The new disk is displayed in the tree view after the rescan. If the new disk is not displayed, restart the system.
For SAS Controllers
1. Check the alert log for an alert verifying that the system has identified the new disk. You may receive alert 2052 or 2294. For information on alert messages, see the Server Administrator Messages Reference Guide.
2. Refresh the display by clicking Refresh ( ) or by changing pages.
NOTE: Clicking the Refresh button in the right pane refreshes only the right pane. To view the new physical disk in the left pane tree view, click the system name displayed at the top of the left pane, or click View > Refresh on the browser.
The new physical disk or physical device is displayed in the tree view after refreshing the display. If the new disk is not displayed, restart the computer.

Replacing A Physical Disk Receiving SMART Alerts
Self Monitoring, Analysis and Reporting Technology (SMART) alerts are messages predicting that a disk may fail soon. If a physical disk is receiving SMART alerts replace the disk. Use the following procedures to replace a disk receiving SMART alerts:
Disk Is Part Of A Redundant Virtual Disk
CAUTION: To avoid potential data loss, perform a check consistency before removing a physical disk that is receiving
SMART alerts. The check consistency verifies that all data is accessible within the redundant virtual disk and uses the redundancy to repair any bad blocks that may be present. In some circumstances, failure to perform a check consistency can result in data loss. This may occur, for example, if the physical disk receiving SMART alerts has bad disk blocks and you do not perform a check consistency before removing the disk.
1. Select the redundant virtual disk that includes the physical disk that is receiving SMART alerts and perform the Check Consistency task. For more information, see
Performing A Check Consistency
2. Select the disk that is receiving SMART alerts and execute the Offline task.
3. Manually remove the disk.
4. Insert a new disk. Make sure that the new disk is the same size or greater in size than the disk you are replacing. On some controllers, you may not be able to use the additional disk space if you insert a disk with a greater disk space than the one you are replacing. For
rebuild is automatically initiated because the virtual disk is redundant.
Disk Is Not Part Of A Redundant Virtual Disk
1. Back up data from the virtual disk.
2. Delete the virtual disk.
3. Replace the disk that is receiving SMART alerts.
4. Create a new virtual disk. Make sure that the new virtual disk is the same size or greater in size than the original virtual disk. For
and
For PERC S100, S110, And S300 Controllers
.
5. Restore the backed up data from the original virtual disk onto the newly created virtual disk.

Blinking And Unblinking A Physical Disk
Does my controller support this feature? See
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 automatically cancels after a short duration such as 30–60 seconds. 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 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.
Removing Dead Segments
Does my controller support this feature? See
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
Does my controller support this feature? See
Use the Prepare to Remove task to spin down a physical disk or physical device so that it can be safely removed from an enclosure or backplane. It is recommended that you perform this task before removing a disk or device to prevent data loss.
This task causes the LED on the disk to blink. You can safely remove the disk or device by following the conditions listed below:
• Wait for about 30 seconds to allow the disk to spin down.
• Wait until you notice the initial blink pattern has changed into a different pattern or the lights have stopped blinking.
A physical disk or physical device is no longer in ready state performing. Removing the physical disk or device from the enclosure or backplane and replacing it causes the physical disk or device to spin up and return to Ready state.
In some cases, a rescan is required for the controller to recognize configuration changes such as the removal of a disk or device.
NOTE: This procedure is not available for physical disks or devices that have been assigned as a hot spare or physical disk or devices that are part of a virtual disk. In addition, this procedure is only supported for hotswap physical disks or devices (disks that reside in a carrier.)

Does my controller support this feature? See
Select the Rebuild task to reconstruct data when a physical disk in a redundant virtual disk fails.
NOTE: Rebuilding a disk may take several hours.

Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk
Physical Disks Or Physical Devices 109
Canceling A Rebuild
Does my controller support this feature? See
Select the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a Degraded state.
The failure of an additional physical disk can cause the virtual disk to fail and may result in data loss. It is recommended that you rebuild the failed physical disk as soon as possible.
NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, reinitiate the rebuild on the same physical disk in order to restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare does not cause the newly assigned hot spare to rebuild the data. Reinitiate the rebuild on the physical disk that was the original hot spare.
Assigning And Unassigning Global Hot Spare
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.
Does my controller support this feature? See
A global hot spare is an unused backup disk that is part of the disk group. Hot spares remain in standby mode. When a physical disk that is used in a virtual disk fails, the assigned hot spare is activated to replace the failed physical disk without interrupting the system or requiring your intervention. When a hot spare is activated, it rebuilds the data for all redundant virtual disks that were using the failed physical disk.
You can change the hot spare assignment by unassigning a disk and choosing another disk as needed. You can also assign more than one physical disk as a global hot spare.
NOTE: On SAS 6/iR controllers, you cannot assign physical disks that have boot partitions, as hot spares.
NOTE: On PERC S100 and S300 controllers, if there is free space available on the global hot spare, it continues to function as a spare even after replacing a failed physical disk.
Global hot spares must be assigned and unassigned manually. They are not assigned to specific virtual disks. If you want to assign a hot spare to a virtual disk (it replaces any physical disk that fails in the virtual disk), then use the Assign and Unassign Dedicated Hot
Spare .
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. When the last virtual disk of a disk group is deleted, all assigned dedicated hot spares automatically become global hot spares.
NOTE: For PERC H310, H700, H710, H710P, H800, H810, H330, H730, H730P, H830, and PERC FD33xD/FD33xS controllers, if any of the drives you selected are in the Spun Down state, the following message is displayed: The current physical drive is in the spun down state. Executing this task on this drive takes additional time, because the drive needs to spun up.
You should be familiar with the size requirements and other considerations associated with hot spares.

Enabling Revertible Hot Spare
Does my controller support this feature? See
Select the Revertible Hot Spare task to copy data back from a hot spare to a physical disk.
If the physical disk in a virtual disk fails, the data on the failed disk is copied to the assigned hot spare. If you replace the failed disk with a new physical disk and if you have enabled the Revertible Hot Spare task, the data is copied from the hot spare to the new disk.
You can also use the Revertible Hot Spare task to copy data from a physical disk to the hot spare on a predictive failure event.
If Revertible Hot Spare is enabled and the physical disk is SMART-enabled, the controller firmware automatically starts copying data from the SMART-enabled disk in the virtual disk to the hot spare.
NOTE: To use the Revertible Hot Spare task, ensure that you have assigned a hot spare to the virtual disk.
NOTE: If the disk is not SMART-enabled or if the Auto Replace on Predictive Failure option is disabled, the failed disk is not replaced automatically.
