Dell PowerVault MD3420 - Manual (Page 47)

Method enclosureLossProtect= TRUE enclosureLossProtect=FALSE
group has enclosure loss
protection.
The enclosureLossProtect parameter is not valid when creating virtual disks on existing disk groups.
Using The Auto Configure Command
The autoConfigure storageArray command creates the disk groups on a storage array, the virtual
disks in the disk groups, and the hot spares for the storage array. When you use the autoConfigure
storageArray command, 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 disks
After defining these parameters, the MD Storage Manager automatically creates the disk groups, virtual
disks, and hot spares. The RAID controller modules assign disk group and virtual disk numbers as they are
created. After MD Storage Manager 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 storageArray
autoConfigure command. The show storageArray autoConfigure command returns a list of
parameter values that MD Storage Manager uses to create a storage array. Change any of the parameter
values by entering new values for the parameters when you run the autoConfigure storageArray
command. If you are satisfied with the parameter values that the show storageArray
autoConfiguration command returns, run the autoConfigure storageArray command without
new parameter values.
The following syntax is the general form of autoConfigure storageArray command:
autoConfigure storageArray [physicalDiskType=
(SAS) raidLevel=(0 | 1 | 5 | 6) | diskGroupWidth=
numberOfPhysicalDisks | diskGroupCount=
numberOfDiskGroups | virtualDisksPerGroupCount=
numberOfVirtualDisksPerGroup | hotSpareCount=
numberOfHotspares | segmentSize=segmentSizeValue]
NOTE: All parameters are optional. You can use one or all of the parameters as needed to define
your configuration.
When you use the autoConfigure storageArray command without specifying the number of disk
groups, the firmware determines how many virtual disks and disk groups to create. The firmware creates
one disk group and one virtual disk up to the maximum number that the storage array can support. When
you specify the number of disk groups, the firmware creates only that number of disk groups. When you
create more than one disk group, all of the disk groups have the same number of physical disks and the
same number of virtual disks.
• The diskGroupWidth parameter defines the number of unassigned physical disks wanted for each
new disk group.
