Formatting the Memory Array

Note: 

The array is formatted to 65% usable capacity at the factory and can 

be used without change.

To change the format of the Memory Array:

1.

Log into the Memory Array.

2.

At the root CLI prompt, type:

Where:

Higher usable percentages provide more usable capacity where needed. Lower 
usable percentages increase system write performance, endurance, and 
reliability. For advice on selecting a good usable percentage, consult with HP 
Customer Support.

format flash-capacity

 [

<value>

]

value

Specifies the percentage of usable flash capacity. Valid values 
are:

•

50

 

•

65

 

•

78

 

•

84

 

•

87

 

•

 — Not recommended for high performance or high reliability 

systems.

Default is 65%.
