HP Array Configuration Utility  88 

•

 

For an existing logical drive, the default setting is the existing setting. 

Logical drive performance is likely to decrease with MaxBoot enabled. 

 

ShrinkSize 

In Reconfigure mode, this option specifies the resulting size of the logical drive (in MB) to be reduced. 

ShrinkSize

 is not valid in Configure mode. 

 

Size 

This parameter specifies the size of the logical drive. 
Use the following values to set the size: 

•

 

N

—The size in MB 

•

 

MAX

—Uses all available unused space in the array for the logical drive. This value is the default. 

•

 

MAXMBR

—Creates the largest size of volume supportable by a 32-bit MBR (2TiB) 

In Reconfigure mode, the default setting is the existing size of the logical drive. If you enter a larger value, 

ACU extends the logical drive to the new size if there is unused drive capacity on the same array, as long as 

the operating system supports logical drive extension. You cannot reduce the size of the logical drive. 

  

 

CAUTION:

  Back up all data before extending a logical drive. 

  

 

SizeBlocks 

This option specifies the size of the logical drive in 512-byte blocks. Use this option to set an exact size 

without rounding. 
When ACU Scripting captures a configuration, it reports volume sizes rounded down to the nearest MB. 

When the capture is played back, the size is reduced to fit within the already rounded MB size. This option 
prevents the loss of volume size over successive generations of captures. 
However, if the size does not fit the geometry of the array, caused by different disks or RAID levels, the size 

will be rounded down to fit the geometry. 

 

StripeSize 

Beginning with ACU, ACU CLI, and ACU Scripting v8.55, the term 

stripe size

 has been replaced by 

strip 

size

. This labeling change does not affect functionality. 

When distributing data across multiple physical drives (striping), the 

strip size

 is the amount of data that is 

written to each physical drive. The 

full stripe size

 refers to the combined size of all the strips across all 

physical drives, excluding parity-only drives. 
For more information, see the option for StripSize (on page 

88

).
