Example 2
This example creates a new volume by using the
create volume
command with
user-defined drives in the storage array.
Show “Create RAID3 Volume 2 on existing Volume Group
2”;
//This command creates the volume group and the
initial volume on that group.
//Note: For volume groups that use all available
capacity, the last volume

on the volume group is created using all remaining
capacity by omitting the

capacity=volume creation parameter
create volume RAIDLevel=3 userLabel=”2” drives=[0,1
0,6 1,7 1,3 2,3 2,6]

owner=B segmentSize=16 capacity=2GB;
show “Setting additional attributes for voluem 7”’

//Configuration settings that cannot be set during
volume creation

set volume [“7”] cacheFlushModifier=10;

set volume [“7”] cacheWithoutBatteryEnabled=false;

set volume [“7”] mirrorEnabled=true;

set volume [“7”] readCacheEnabled=true;

set volume [“7”] writeCacheEnabled=true;

set volume [“7”] mediaScanEnabled=false;

set volume [“7”] redundantCheckEnabled=false;

set volume [“7”] modificationPriority=high;
The command in this example, like the
create volume
command in the previous
example, creates a new volume. The significant difference between these two
examples is that this example shows how you can define specific drives to include in
the volume. Use the
show storageArray profile
command to find out what
drives are available in a storage array.
The
create volume
command takes this form:
create volume raidLevel=(0 | 1 | 3 | 5 | 6)
userLabel= volumeName

drives=(trayID1,slotID1... trayIDn , slotIDn )

[capacity= volumeCapacity | owner=(a | b) |

cacheReadPrefetch=(TRUE | FALSE) |

segmentSize= segmentSizeValue ]

[trayLossProtect=(TRUE | FALSE)]
