Recurring syntax elements

Recurring syntax elements are a general category of parameters and options that you can use in the script commands. The following table lists the conventions used in the recurring syntax elements.

Convention	Definition
a \| b	Alternative ("a" or "b")
italicized-words	Needs user input to fulfill a parameter (a response to a variable)
[ ... ] (square brackets)	Zero or one occurrence (square brackets are also used as a delimiter for some command parameters)
{ ... } (curly braces)	Zero or more occurrences
(a \| b \| c)	Choose only one of the alternatives

The following table lists the recurring syntax parameters and the values that you can use with the recurring syntax parameters.

¹For tray loss protection to work, your configuration must adhere to the following guidelines:

Level	Criteria for Shelf Loss Protection	Minimum number of shelves required
Pool	The pool contains no more than two drives in a single shelf.	6
RAID 6	The volume group contains no more than two drives in a single shelf.	3
RAID 3 or RAID 5	Each drive in the volume group is located in a separate shelf.	3
RAID 1	Each drive in a RAID 1 pair must be located in a separate shelf.	2
RAID 0	Cannot achieve Shelf Loss Protection.	Not applicable

²For drawer loss protection to work, your configuration must adhere to the following guidelines:

Level	Criteria for drawer loss protection	Minimum number of drawers required
Pool	The pool includes drives from all five drawers and there are an equal number of drives in each drawer. A 60-drive shelf can achieve Drawer Loss Protection when the pool contains 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 drives.	5
RAID 6	The volume group contains no more than two drives in a single drawer.	3
RAID 3 or RAID 5	Each drive in the volume group is located in a separate drawer.	3
RAID 1	Each drive in a mirrored pair must be located in a separate drawer.	2
RAID 0	Cannot achieve Drawer Loss Protection.	Not applicable

If you have a storage array configuration in which a volume group spans several trays, you must make sure that the setting for drawer loss protection works with the setting for tray loss protection. You can have drawer loss protection without tray loss protection. You cannot have tray loss protection without drawer loss protection. If the trayLossProtect parameter and the drawerLossProtect parameter are not set to the same value, the storage array returns an error message and a storage array configuration will not be created.

³ To determine if a free capacity area exists, run the show volumeGroup command.

⁴ The default drive (drive type) is SAS.

The driveType parameter is not required if only one type of drive is in the storage array. If you use the driveType parameter, you also must use the hotSpareCount parameter and the volumeGroupWidth parameter.

⁵ The dataAssurance parameter relates to the Data Assurance (DA) feature.

The Data Assurance (DA) feature increases data integrity across the storage system. DA enables the storage array to check for errors that might occur when data is moved between the controllers and drives. When this feature is enabled, the storage array appends error-checking codes (also known as cyclic redundancy checks or CRCs) to each block of data in the volume. After a data block is moved, the storage array uses these CRC codes to determine if any errors occurred during transmission. Potentially corrupted data is not written to disk.

Note

When all the required hardware and the I/O interface is DA-capable, you can set the dataAssurance parameter to enabled and then use DA with certain operations. For example, you can create a volume group that includes DA-capable drives, and then create a volume within that volume group that is DA-enabled. Other operations that use a DA-enabled volume have options to support the DA feature.

⁶ The volumesPerGroupCount parameter is the number of equal-capacity volumes per volume group.

⁷ The securityType parameter enables you to specify the security setting for a volume group that you are creating. All of the volumes are also set to the security setting that you choose. Available options for setting the security setting include:

none – The volume group is not secure.
capable – The volume group is security capable, but security has not been enabled.
enabled – The volume group is security enabled.

Note

A storage array security key must already be created for the storage array if you want to set securityType=enabled. (To create a storage array security key, use the create storageArray securityKey command.)
