SANtricity 11.8 Commands ( CA08871-194 ~ 196 )

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 Series

This command applies to any individual storage system, including the HB2100/HB2200/HB2300, HB5100/HB5200, AB6100 and AB3100 series, as long as all SMcli packages are installed.

Roles

To execute this command on an HB2100/HB2200/HB2300, HB5100/HB5200, AB6100, or AB3100 storage system, you must have the Storage Admin role.

Syntax

check volume [volumeName] parity
[parityErrorFile=filename]
[mediaErrorFile=filename]
[priority=(highest | high | medium | low | lowest)]
[startingLBA=LBAvalue]
[endingLBA=LBAvalue]
[verbose=(TRUE | FALSE)]

Parameters

Parameter Description

volume

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.

parityErrorFile

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:

file="C:\Program Files\CLI\logs\parerr.txt"

This command does not automatically append a file extension to the saved file. You must specify a file extension when entering the file name.

mediaErrorFile

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:

file="C:\Program Files\CLI\logs\mederr.txt"

This command does not automatically append a file extension to the saved file. You must specify a file extension when entering the file name.

priority

The priority that the parity check has relative to host I/O activity. Valid values are highest, high, medium, low, or lowest.The lowest priority rate benefits system performance, but the parity check takes longer. The highest priority rate benefits the parity check, but system performance might be compromised.

startingLBA

The starting logical block address.

endingLBA

The ending logical block address.

verbose

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 TRUE. To prevent capturing progress details, set this parameter to FALSE.

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.
