Configuring a Storage Array
53
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] or Serial Advanced
Technology Attachment [SATA])
• 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 will use 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 | SATA) raidLevel=(0 | 1 | 5 | 6) |
diskGroupWidth= numberOfPhysicalDisks |
diskGroupCount= numberOfDiskGroups |
virtualDisksPerGroupCount=
numberOfVirtualDisksPerGroup | hotSpareCount=
numberOfHotspares | segmentSize= segmentSizeValue ]
