Activate Remote Replication Feature

  • NOTE: This command is used to activate both Remote Replication and Remote Replication (Legacy).

Description

This command creates the replication repository virtual disks and activates the Remote Replication and Remote Replication (legacy) premium features. When using this command, the replication repository virtual disk can be defined in one of three ways:
  • User-defined physical disks
  • User-defined disk group
  • User-defined number of physical disks
If you define a number of physical disks, the RAID controller module firmware selects which physical disks to use for the replication repository virtual disk.

Syntax

Parameters

Parameter

Description

repositoryRAIDLevel

The RAID level for the replication repository virtual disk. Valid values are 0 , 1 , 5 , or 6 .

repositoryPhysicalDisks

The physical disks for the replication repository virtual disk. For dense expansion enclosures, specify the enclosure ID value, the drawer ID value, and the slot ID value for each physical disk that you assign to the replication repository virtual disk. For non-dense expansion enclosures, specify the enclosure ID value and the slot ID value for each physical disk that you assign to the replication repository virtual disk. Enclosure ID values are 0 to 99 . Drawer ID values are 0 to 4 . Slot ID values are 0 to 31 . Enclose the enclosure ID values, the drawer ID values, and the slot ID values in parentheses.

repositoryDiskGroupUserLabel

The name that you want to give the new disk group in which the replication repository virtual disk is located. Enclose the disk group name in double quotation marks (" ").

repositoryDiskGroup

The name of the replication repository disk group where the replication repository virtual disk is located.

To determine the names of the disk groups in your storage array, run the show storageArray profile command.

freeCapacityArea

The index number of the free space in an existing disk group that you want to use to create the replication repository virtual disk. Free capacity is defined as the free capacity between existing virtual disks in a disk group. For example, a disk group might have the following areas: virtual disk 1, free capacity, virtual disk 2, free capacity, virtual disk 3, free capacity. To use the free capacity following virtual disk 2, you would specify:

freeCapacityArea=2

Run the show diskGroup command to determine if a free capacity area exists.

repositoryPhysicalDiskCount

The number of unassigned physical disks that you want to use for the replication repository virtual disk.

enclosureLossProtect

The setting to enforce enclosure loss protection when you create the replication repository virtual disk. To enforce enclosure loss protection, set this parameter to TRUE . The default value is FALSE .

drawerLossProtect

The setting to enforce drawer loss protection when you create the replication repository virtual disk. To enforce drawer loss protection, set this parameter to TRUE . The default value is FALSE .

dataAssurance

The setting to specify that a disk group, and the virtual disks within the disk group, has data assurance protection to make sure that the data maintains its integrity. When you use this parameter, only protected physical disks can be used for the disk group. These settings are valid:
  • none - The disk group does not have data assurance protection.
  • enabled - The disk group has data assurance protection. The disk group supports protected information and is formatted with protection information enabled.
    • NOTE: This option is only valid for enablement, if the drives support DA.

Notes

The repositoryPhysicalDisks parameter supports both dense expansion enclosures and non-dense expansion enclosures. A dense expansion enclosure has drawers that hold the physical disks. The drawers slide out of the expansion enclosure to provide access to the physical disks. A non-dense expansion enclosure does not have drawers. For a dense expansion enclosure, you must specify the identifier (ID) of the expansion enclosure, the ID of the drawer, and the ID of the slot in which a physical disk resides. For a non-dense expansion enclosure, you need only specify the ID of the expansion enclosure and the ID of the slot in which a physical disk resides. For a non-dense expansion enclosure, an alternative method for identifying a location for a physical disk is to specify the ID of the expansion enclosure, set the ID of the drawer to 0 , and specify the ID of the slot in which a physical disk resides.

If the physical disks that you select for the repositoryPhysicalDisks parameter are not compatible with other parameters (such as the repositoryRAIDLevel parameter), the script command returns an error, and Remote Replication (Legacy) is not activated. The error returns the amount of space that is needed for the replication repository virtual disk. You can then re-enter the command, and specify the appropriate amount of space.

If you enter a value for the repository storage space that is too small for the replication repository virtual disks, the RAID controller module firmware returns an error message that provides the amount of space that is needed for the replication repository virtual disks. The command does not try to activate Remote Replication (Legacy). You can re-enter the command by using the value from the error message for the repository storage space value.

When you assign the physical disks, if you set the enclosureLossProtect parameter to TRUE and have selected more than one physical disk from any one enclosure, the storage array returns an error. If you set the enclosureLossProtect parameter to FALSE , the storage array performs operations, but the disk group that you create might not have enclosure loss protection.

When the RAID controller module firmware assigns the physical disks, if you set the enclosureLossProtect parameter to TRUE , the storage array returns an error if the RAID controller module firmware cannot provide physical disks that result in the new disk group having enclosure loss protection. If you set the enclosureLossProtect parameter to FALSE , the storage array performs the operation even if it means that the disk group might not have enclosure loss protection.

The drawerLossProtect parameter defines if data on a virtual disk is accessible if a drawer fails. When you assign the physical disks, if you set the drawerLossProtect parameter to TRUE and select more than one physical disk from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter to FALSE , the storage array performs operations, but the disk group that you create might not have drawer loss protection.

You must set the enclosureLossProtect parameter and the drawerLossProtect parameter to the same value. Both of the parameters must be either TRUE or FALSE . If the enclosureLossProtect parameter and the drawerLossProtect parameter is set to different values, the storage array returns an error.
