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.
SSPAdaptersWithAccess
Enter values here to identify the SSP adapters that you want to have access to a logical drive. The
values are processed only if either SSPState or LogicalDriveSSPState is set to Enable. Otherwise,
the values are ignored.
NOTE:
Be sure that every HBA in the system has access to the logical drives for which multi-path
will be used.
StripeSize
You can enter a numerical value for this option to specify the size of the data stripes (in kilobytes),
or you can leave this option blank and allow HP SSA to use a default value.
The valid stripe size values depend on the RAID level.
•
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 HP SSA version, the controller model,
and the controller firmware version.
◦
For RAID 0, RAID 1, or RAID 1+0, the default value is 128 KB.
◦
For RAID 5, the default value is usually 64 KB, but on some controller models it is 16 KB
or 128 KB.
◦
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, HP SSA 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
This option is a user-defined string used as the connection name for the specified HBA.
