Dell PowerVault MD3260i - Manual (Page 131)

Parameter Description
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.
Notes
• If the physical disks selected 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. The command can then be re-entered with the appropriate amount of space
specified.
• 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 provides the amount of space that is needed
for the replication repository virtual disks. The command does not try to activate Remote Replication (legacy).
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 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. Either both the parameters must be TRUE or
both must be FALSE. If the enclosureLossProtect parameter and the drawerLossProtect
parameter are set to different values, the storage array returns an error.
