Re-Create Remote Replication Repository Virtual Disk

Description

NOTE: This command is valid only with Fibre Channel storage arrays.

This command creates a new Remote Replication repository virtual disk (also called a replication repository virtual disk) by using the parameters defined for a previous replication repository virtual disk. The underlying requirement is that you have previously created a replication repository virtual disk. 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 choose to define a number of physical disks, the RAID controller module firmware chooses which physical disks to use for the replication repository virtual disk.

Syntax

User-Defined Physical Disks

recreate storageArray replicationRepository repositoryRAIDLevel=(1 | 5 | 6) repositoryPhysicalDisks=(enclosureID1,drawerID1,slotID1
                                 ... enclosureIDN,drawerIDN,slotIDN) [enclosureLossProtect=(TRUE | FALSE)][dataAssurance=(none | enabled)]

User-Defined Disk Group

recreate storageArray replicationRepository
                                 repositoryDiskGroup=
                                 diskGroupName
                                    
                                 [freeCapacityArea=
                                 freeCapacityIndexNumber]

User-Defined Number of Drives

recreate storageArray replicationRepository 
                                 repositoryRAIDLevel=(1 | 5 | 6) repositoryPhysicalDiskCount=numberOfPhysicalDisks [physicalDiskType=(SAS)] 
                                 [enclosureLossProtect=(TRUE | FALSE)] 
                                 [dataAssurance=(none | enabled)]

Parameters

Parameter	Description
`repositoryRAIDLevel`	The RAID level for the replication repository virtual disk. Valid values are `1`, `5`, or `6`.
`repositoryPhysicalDisks`	The physical disks for the replication repository virtual disk. Specify the enclosure ID and slot ID for each physical disk that you assign to the replication repository virtual disk. Enclosure ID values are `0` to `99`. Slot ID values are `1` to `32`. Enclose the enclosure ID values and the slot ID values in parentheses.
`repositoryDiskGroup`	The name of the disk group where the replication repository virtual disk is located.
`freeCapacityArea`	The index number of the free space in an existing disk group that you want to use to re-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`.
physicalDiskType	The type of physical disk that you want to use for the replication repository virtual disk. You cannot mix physical disk types. You must use this parameter when you have more than one type of physical disk in your storage array. Valid physical disk types are : SAS If you do not specify a physical disk type, the command defaults to SAS.
dataAssurance	The setting to specify that a disk pool 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 pool. These settings are valid: none – The disk pool does not have data assurance protection. enabled – The disk pool has data assurance protection. The disk pool supports protected information and is formatted with protection information enabled. The default value is none. NOTE: This option is only valid for enablement, if the physical disks supports DA.

Notes

If a value is entered 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 indicates the amount of space needed for the replication repository virtual disks. The command does not try to change the replication repository virtual disk. The command can be re-entered 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 replication repository virtual disk having enclosure loss protection. If you set the enclosureLossProtect parameter to FALSE, the storage array performs the operation even if it means that the replication repository virtual disk might not have enclosure loss protection.
