Changing Raid Protection Types - Lenovo px4-300d User Manual

Changing RAID Protection Types

You can change the RAID protection of existing Storage Pools. You can also set the RAID protection type
when you add drives to your px4-300d Network Storage and
can be changed only when the Storage Pool is in a normal (healthy) state. If you are unfamiliar with RAID
protection, it is recommended that you do not change this setting.
Most changes to protection type will delete all data on the Storage Pool. You can make the
following protection type changes without deleting data:
Expanding a RAID 5 configuration by adding one or more drives.
●
Migrating from RAID 1 with two disks to a RAID 5 configuration with three or more disks.
●
Migrating from JBOD with one disk to RAID 1 with two disks.
●
To change the RAID type, expand the Information section of a Storage Pool on the Drive Management
page, and choose a value from the Protection drop-down menu:
Mirror (RAID 1)
●
Mirror Stripe (RAID 10)
●
Parity (RAID 5)
●
None (RAID 0)
●
For additional explanation on these RAID types, refer to
Note that the displayed available capacity changes as you select different RAID types from the Protection
drop-down menu. RAID array capacity is based on drive use, which differs for some RAID types.
Click Apply to change the RAID protection.
Click Cancel to retain your previous RAID configuration.
