Chapter 4: Configuring a Storage Array 59
Example of the Auto Configuration Command
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “autoConfigure storageArray driveType=fibre

raidLevel=5 volumeGroupWidth=8 volumeGroupCount=3

volumesPerGroupCount=4 hotSpareCount=2

segmentSize=8 cacheReadPrefetch=TRUE;”
The command in this example creates a storage array configuration by using Fibre
Channel drives set to RAID Level 5. Three volume groups are created, and each
volume group consists of eight drives, which are configured into four volumes. The
storage array has two hot spares. The segment size for each volume is 8 KB. The
cache read prefetch is turned on, which causes additional data blocks to be written
into the cache.
Using the Create
Volume Command
Use the
create volume
command to create new storage array volumes in three
ways:

Create a new volume while simultaneously creating a new volume group to
which you assign the drives.

Create a new volume while simultaneously creating a new volume group to
which the storage management software assigns the drives.

Create a new volume in an existing volume group.
You must have unassigned drives in the volume group. You do not need to assign the
entire capacity of the volume group to a volume.
Creating Volumes with
User-Assigned Drives
When you create a new volume and assign the drives you want to use, the storage
management software creates a new volume group. The controller firmware assigns a
volume group number to the new volume group. The command has this form:
create volume drives=( trayID1, slotID1... trayIDn,
slotIDn )

raidLevel=(0 | 1 | 3 | 5 | 6) userLabel=” volumeName ”

[volumeGroup=[ volumeGroupName ]

capacity= volumeCapacity owner=(a | b)

cacheReadPrefetch=(TRUE | FALSE)

segmentSize= segmentSizeValue

trayLossProtect=(TRUE | FALSE)]
