Dell PowerVault MD3620f Command Line Interface Manual page 102

The RAID level that you choose for the replication repository virtual disk has
these constraints:
• RAID Level 0 – You cannot use RAID Level 0.
• RAID Level 1 – The number of physical disks must be an even number. If
you select an odd number of physical disks, the RAID controller module
firmware returns an error.
• RAID Level 5 – You must have a minimum of three physical disks in the
disk group.
• RAID Level 6 – You must have a minimum of five physical disks in the disk
group.
To activate the Remote Replication premium feature, use this command:
activate storageArray feature=remoteReplication
The activate storageArray feature=remoteReplication
command provides three methods for defining the physical disks for your
replication repository virtual disk:
• You define each physical disk for the replication repository virtual disk by
its enclosure ID and its slot ID.
• You define a disk group in which the replication repository virtual disk
resides. You can optionally define the capacity of the replication repository
virtual disk.
• You define the number of physical disks, but not specific physical disks, for
the replication repository virtual disk.
Activating the Remote Replication Premium Feature with User-Assigned Physical
Disks
Activating the Remote Replication premium feature by assigning the physical
disks provides flexibility in defining your configuration by letting you choose
from the available physical disks in your storage array. Choosing the physical
disks for your remote replication automatically creates a new disk group. You
can specify which physical disks to use and the RAID level for the new disk
group.
The command takes this form:
activate storageArray feature=remoteReplication
repositoryRAIDLevel=(1 | 5 | 6)
