For RAID 0, RAID 1, or RAID 1+0 arrays, you can enter any of the stripe size values listed in the

sample script.

For RAID 5 arrays, the maximum stripe size in most cases is 256 KB, but old controller models are

often limited to 64 KB.

For RAID 6 arrays, the maximum stripe size is either 64 KB or 256 KB, depending on the controller.

The default stripe 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 some cases, it also depends on the ACU version, the controller model, and the
controller firmware version).

o

For RAID 0, RAID 1, or RAID 1+0, the default value is 128 KB.

o

For RAID 5, the default value is usually 64 KB, but on some controller models it is 16 KB or 128
KB.

o

For RAID 6, the default value is usually 16 KB, but on some controller models it is 64 KB or 128
KB.

In Reconfigure action mode, the default value for this option is the stripe size that is already
configured for the logical drive. If you enter a value that is different from the existing stripe size,

ACU attempts to migrate the logical drive to the stripe 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

52

)

HBA_WW_ID (on page

52

)

HostMode (on page

52

)

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.

HostMode

This option specifies the HostMode for a selected HBA. Setting the Host Mode optimizes the storage array
for the selected operating system. The available host modes for an HBA are device-specific. Not all
modes are available on all devices. Not all HBAs support a HostMode.
The following operating system options might be available:
