This command checks a logical drive for parity and media errors and writes the results of the check to a file.
check logicalDrive [logicalDriveName] parity [parityErrorFile=filename] [mediaErrorFile=filename] [priority=(highest | high | medium | low | lowest)] [startingLBA=LBAvalue] [endingLBA=LBAvalue] [verbose=(TRUE | FALSE)]
Parameter | Description |
---|---|
logicalDrive | The name of the specific logical drive for which you want to check parity. Enclose the logical drive name in square brackets ([ ]). If the logical drive name has special characters, you also must enclose the logical drive name in double quotation marks (“ ”). |
parityErrorFile | The name of the file in which you want to save the parity error information. Enclose the file name in double quotation marks (“ ”). |
mediaErrorFile | The name of the file in which you want to save the media error information. Enclose the file name in double quotation marks (“ ”). |
priority |
The priority that the parity check has relative to host I/O activity. Valid values are highest, high, medium, low, or lowest. |
startingLBA | The starting logical block address. Use integer values. |
endingLBA | The ending logical block address. Use integer values. |
verbose |
The setting to capture progress details, such as percent complete, and to show the information as the logical drive parity is being repaired. To capture progress details, set this parameter to TRUE. To prevent capturing progress details, set this parameter to FALSE. |
The starting logical block address and the ending logical block address are useful for very large single-logical drive LUNs. Running a logical drive parity check on a very large single logical drive LUN can take a long time. By defining the beginning address and ending address of the data blocks, you can reduce the time that a logical drive parity check takes to complete.
