HP Array Configuration Utility 89
You can enter a numerical value for this option to specify the size of the data strips (in kilobytes), or you can
leave this option blank and allow ACU to use a default value.
Strip sizes available for a RAID level vary based on the controller and the controller firmware level. The
maximum strip size changes dynamically and is reduced for arrays with a large number of data drives or
with smaller controller cache sizes. (The controller must be able to read an entire stripe of data at a time into
cache memory during transformation. Available memory is the limiting factor.
The following strip sizes are available:

The default strip size value depends on the action mode:
•
In Configure action mode, the default value is determined by the RAID level that you specified earlier in
the script.
•
In Reconfigure action mode, the default value for this option is the strip size that is already configured
for the logical drive. If you enter a value that is different from the existing strip size, ACU attempts to
migrate the logical drive to the strip size that you specify. (If you intend to migrate the logical drive, back
up all data before starting the migration procedure.)
HBA category
The HBA category has the following options:
•
ConnectionName (on page
89
)
•
HBA_WW_ID (on page
89
)
•
HostMode (on page
90
)
ConnectionName
This option is a user-defined string used as the connection name for the specified HBA.
The string can consist of:
•
A maximum of 16 characters
•
Embedded space characters but cannot end with a space character
•
Any of the following characters: a–z, A–Z, 0–9, !, @, #, *, (, ), -, _, +, :, ., /, and [space]
HBA_WW_ID
This option specifies which HBA, based on its assigned WWN, is modified by the configuration changes.
