Replacing a drive
Guidelines
The drives are hot swappable.
If you are using the drives to create a RAID, follow these restrictions and guidelines:
· To avoid degraded RAID performance or RAID creation failures, make sure all drives in the RAID are the same type (HDDs or SSDs) and have the same connector type (SAS or SATA).
· For efficient use of storage, use drives that have the same capacity to build a RAID. If the drives have different capacities, the lowest capacity is used across all drives in the RAID.
· Back up drive data before replacement.
· If the installed drive contains RAID information, you must clear the information before configuring RAIDs. As a best practice, install drives that do not contain RAID information.
Prerequisites
Identify the position of the drive to be replaced.
Identify the RAID array information of the drive to be replaced.
Procedure
1. Remove the security bezel, if any. For more information, see "Removing the security bezel."
