Check volume parity
The check volume parity
command checks a volume for parity and media errors, and then writes the results of the check to a file.
Supported Arrays
This command applies to any individual storage array, including the E4000, E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.
Roles
To execute this command on an E4000, E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.
Syntax

[endingLBA=LBAvalue]
[verbose=(TRUE | FALSE)]
Parameters
Parameter | Description |
---|---|
|
The name of the specific volume for which you want to check parity. Enclose the volume name in square brackets ([ ]). If the volume name contains special characters or consists only of numbers, you must enclose the identifier in double quotation marks (" ") inside square brackets. |
|
The file path and the file name to which you want to save the parity error information. Enclose the file name in double quotation marks (" "). For example:
This command does not automatically append a file extension to the saved file. You must specify a file extension when entering the file name. |
|
The file path and the file name to which you want to save the media error information. Enclose the file name in double quotation marks (" "). For example:
This command does not automatically append a file extension to the saved file. You must specify a file extension when entering the file name. |
|
The priority that the parity check has relative to host I/O activity. Valid values are |
|
The starting logical block address. |
|
The ending logical block address. |
|
The setting to capture progress details, such as percent complete, and to show the information as the volume parity is being scanned. To capture progress details, set this parameter to |
Notes
The starting logical block address and the ending logical block address are useful for very large single-volume LUNs or namespaces. Running a volume parity check on a very large single volume LUN or namespace can take a long time. By defining the beginning address and ending address of the data blocks, you can reduce the time that a volume parity check takes to complete.
