The freeCapacityArea parameter defines the free capacity area to use for the virtual disk. If a disk group hasseveral free capacity areas, you can use this parameter to identify which free capacity area to use for virtual diskcreation. You do not have to assign the entire capacity of the physical disks to the virtual disk. Assign any unused spaceto another virtual disk at another time.The userLabel, capacity, owner, and segmentSize parameters are the same as in the previous versions ofthe create virtualDisk command.Enclosure Loss ProtectionThe enclosureLossProtect parameter is a boolean switch that turns enclosure loss protection on or off. To workproperly, each physical disk in a virtual disk group must be in a separate enclosure. Enclosure loss protection is setunder the following conditions:• You assign the physical disks.• The RAID controller module assigns the physical disks.The following table shows possible results for the enclosureLossProtect parameter. The results depend onwhether you assign the physical disks or the RAID controller module assigns the physical disks.Method enclosureLossProtect= TRUE enclosureLossProtect=FALSEYou assign the physical disks. If you select more than one physicaldisk from any one enclosure, thestorage array returns an error.The storage array performs theoperation, but the created disk groupdoes not have enclosure lossprotection.The RAID controller module firmwareassigns the physical disks.The storage array posts an error if theRAID controller module firmwarecannot provide physical disks toensure that the new disk group hasenclosure loss protection.The storage array performs theoperation even if it means that thedisk group might not have enclosureloss protection.The enclosureLossProtect parameter is not valid when creating virtual disks on existing disk groups.Using The Auto Configure CommandThe autoConfigure storageArray command creates the disk groups on a storage array, the virtual disks in thedisk groups, and the hot spares for the storage array. When you use the autoConfigure storageArraycommand, define the following parameters:• Type of physical disks (Serial Attached SCSI [SAS])• RAID level• Number of physical disks in a disk group• Number of disk groups• Number of virtual disks in each disk group• Number of hot spares• Size of each segment on the physical disksAfter defining these parameters, the MD Storage Manager automatically creates the disk groups, virtual disks, and hotspares. The RAID controller modules assign disk group and virtual disk numbers as they are created. After MD StorageManager creates the initial configuration, you can use the set virtualDisk command to define virtual disk labels.Before running the autoConfigure storageArray command, run the show storageArrayautoConfigure command. The show storageArray autoConfigure command returns a list of parameter38
