l If you want to include the new disk in a virtual disk, see Virtual Disk Considerations for PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, PERC 5/E, PERC 5/i,

How to Avoid Removing the Wrong Disk
You can avoid removing the wrong disk by blinking the LED display on the disk that you want to remove. For information on blinking the LED display:
l See Blink and Unblink (Physical Disk) to blink the LED display on a physical disk.
l See Blink and Unblink (Virtual Disk) to blink the LED display on all physical disks included in a particular virtual disk.
If you have already removed the wrong disk, see Recovering from Removing the Wrong Physical Disk.
Replacing a Physical Disk Receiving SMART Alerts
SMART alerts are messages predicting that a disk may fail in the near future. If a physical disk is receiving SMART alerts, you should replace the disk. Use the
following procedures to replace a disk receiving SMART alerts.
If the disk is part of a redundant virtual 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 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 larger as the disk you are replacing. On some controllers, you may not be able to use
the additional disk space if you insert a larger disk. For more information, see Virtual Disk Considerations for PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di,
PERC 5/E, PERC 5/i, PERC 6/E, and PERC 6/I Controllers. After you complete this procedure, a rebuild is automatically initiated because the virtual disk is
redundant.
If the 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 larger than the original virtual disk. For controller-specific information
on creating virtual disks, see Virtual Disk Considerations for PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, PERC 5/E, PERC 5/i, PERC 6/E, and PERC 6/I
Controllers and Virtual Disk Considerations for CERC SATA1.5/6ch, and CERC SATA1.5/2s Controllers.
5. Restore the backed up data from the original virtual disk onto the newly created virtual disk.

CAUTION: To avoid potential data loss, you should 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.
