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
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 HP SSA 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 strip of data at a time into cache memory during transformation. Available memory is the limiting factor.
The following strip sizes are available:
•
•
•
•
•
•
•
•
•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, HP SSA 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.)
Encryption support commands
The following commands have been added to HP SSA Scripting versions 1.60.0.0 and later to support data encryption features introduced with select Gen8+ controllers.
Encryption controller category
AllowPlainText
This command allows future plaintext volumes to be created when encryption is enabled. Existing volumes are not modified. To toggle this command, use Yes or No values.
AcceptEULA
The command Yes accepts the Encryption End User License Agreement. The EULA must be accepted before Encryption can be enabled.
ControllerPassword
This command sets the boot time controller password. Enter the password as the value.
