Activate Remote Virtual Disk Mirroring Feature

Activate Remote Virtual Disk Mirroring Feature

This command creates the mirror repository virtual disk and activates the Remote Virtual Disk Mirroring feature. When you use this command, you can define the mirror repository virtual disk 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 mirror repository virtual disk.

Syntax (User-Defined Physical Disks)

activate storageArray feature=remoteMirror repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryPhysical Disks=(trayID1,slotID1 ... trayIDn,slotIDn) [enclosureLossProtect=(TRUE | FALSE)]

Syntax (User-Defined Disk Group)

activate storageArray feature=remoteMirror repositoryDiskGroup= DiskGroup Name [freeCapacityArea=freeCapacityIndexNumber]

Syntax (User-Defined Number of Physical Disks)

activate storageArray feature=remoteMirror repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDriveCount=numberOfPhysical Disks [driveType=(fibre | SATA | SAS | PATA) [enclosureLossProtect=(TRUE | FALSE)]

Parameters

Parameter Description

repositoryRAIDLevel
The RAID level for the repository virtual disk. Valid values are 1, 3, 5, or 6.

repositoryPhysical Disks
The physical disks for the repository virtual disk. Specify the enclosure ID and slot ID for each physical disk you assign to the virtual disk. Enclosure ID values are 0 to 99. Slot ID values are 1 to 32. Enclose the enclosure ID and slot ID values in parentheses.

repositoryDiskGroup
The name of the mirror repository disk group where the mirror repository virtual disk is located. (To determine the name of the disk groups n 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 remote virtual disk mirror repository virtual disks. Free capacity area 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.Use the show DiskGroup command to determine if free capacity area exists.

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

driveType
The type of physical disks that you want to use for the repository virtual disk. Valid physical disk types are fibre, SATA, SAS,or PATA. Use this parameter only when you use the repositoryDriveCount parameter. You need to use this parameter only when you have more than one type of physical disk in your storage array.

enclosureLossProtect
Specifies that enclosure loss protection will be enforced when creating the repository. To enforce enclosure loss protection, set this parameter to TRUE. The default setting is FALSE.

Notes

If the physical disks that you select for the repositoryPhysical Disks parameter are not compatible with other parameters (such as the repositoryRAIDLevel parameter), the script command returns an error, and Remote Virtual Disk Mirroring is not activated. The error returns the amount of space that is needed for the mirror 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 mirror repository virtual disks, the RAID controller module firmware returns an error message that provides the amount of space that is needed for the mirror repository virtual disks. The command does not try to activate Remote Virtual Disk Mirroring. 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.

Parameter	Description
`repositoryRAIDLevel`	The RAID level for the repository virtual disk. Valid values are 1, 3, 5, or 6.
`repositoryPhysical Disks`	The physical disks for the repository virtual disk. Specify the enclosure ID and slot ID for each physical disk you assign to the virtual disk. Enclosure ID values are 0 to 99. Slot ID values are 1 to 32. Enclose the enclosure ID and slot ID values in parentheses.
`repositoryDiskGroup`	The name of the mirror repository disk group where the mirror repository virtual disk is located. (To determine the name of the disk groups n 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 remote virtual disk mirror repository virtual disks. Free capacity area 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.`Use the `show DiskGroup` command to determine if free capacity area exists.
`repositoryDriveCount`	The number of unassigned physical disks that you want to use for the repository virtual disk.
`driveType`	The type of physical disks that you want to use for the repository virtual disk. Valid physical disk types are fibre, SATA, SAS,or PATA. Use this parameter only when you use the `repositoryDriveCount` parameter. You need to use this parameter only when you have more than one type of physical disk in your storage array.
`enclosureLossProtect`	Specifies that enclosure loss protection will be enforced when creating the repository. To enforce enclosure loss protection, set this parameter to TRUE. The default setting is FALSE.
