controller module. If you enter a value for the repository storage space that is too small for the
replication repository virtual disks, the firmware returns an error message that gives the amount of space
needed for the replication repository virtual disks. The command does not try to activate the Remote
Replication (legacy) premium feature. You can re-enter the command using the value from the error
message for the repository storage space value.
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 (legacy) 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 (Legacy) Premium Feature With User-Assigned Physical
Disks
Activating the Remote Replication (legacy) 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)
repositoryPhysicalDisks=(enclosureID1,slotID1 ...
enclosureIDn,slotIDn)
enclosureLossProtect=(TRUE | FALSE)
This example shows a command in which you assign the physical disks:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “activate storageArray feature=remoteReplication
repositoryRAIDLevel=5
repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);”
The command in this example creates a new replication repository virtual disk consisting of five physical
disks that form a new disk group. The new disk group has RAID Level 5.
