20 Creating RAID Using Lifecycle Controller
block of data when you write to the HDD. It returns these values on a read request. When you read or
write data to an HDD, the data is checked for errors.
Select this option to enable T10 Protection Information Capability on a virtual disk and select one of the
following types of T10 protection information capabilities:
 All — Indicates both T10 Protection Information capable and non-T10 protection information-
capable HDDs are selected.
 T10 PI Capable — Indicates that only T10 Protection Information Capable HDDs are selected.
 Non-T10 PI Capable — Indicates that only non-T10 Protection Information Capable HDDs are
selected.
2.16 Secure Virtual Disk
Select this option to secure the virtual disk with the controller security key. The secure virtual disk is
created only if the controller security key is created and the selected virtual disks are self-encryption–
capable drives (SEDs).
2.17 Assign a Hot-Spare HDD (if Available)
Use this option to assign hot-spare HDD to a virtual disk.
A hot-spare is an unused backup HDD that is used to rebuild data from a redundant virtual disk in case of a
HDD failure. A hot-spare can be used only with a redundant RAID level. Hot-spares also have requirements
for HDD size. The hot-spare must have the same or higher disk space than the smallest HDD included in
the virtual disk. If the RAID level and HDD availability do not meet these requirements, the Assign Hot-
spare option is disabled.
2.18 Hot-spare HDD
Select an HDD that will be used as a hot-spare. Only one dedicated hot-spare is supported in Lifecycle
Controller.
NOTE: RAID 0 does not provide data redundancy hence you cannot assign.
