Check Virtual Disk Consistency

Description

This command checks a virtual disk for consistency and media errors, and writes the results of the check to a file.

Syntax

check virtualDisk [
                                 virtualDiskName]
                                 consistency [consistencyErrorFile=
                                 filename]
                                 [mediaErrorFile=
                                 filename]
                                 [priority=(highest | high | medium | low | lowest)]
                                 [startingLBA=
                                 LBAvalue] [endingLBA=
                                 LBAvalue]
                                 [verbose=(TRUE | FALSE)]

Parameters

Parameter	Description
`virtualDisk`	Name of the specific virtual disk to check consistency. You must put brackets ([ ]) around the virtual disk name. If the virtual disk name has special characters, you must also put quotation marks (" ") around the virtual disk name.
`consistencyErrorFile`	Name of the file in which to save the consistency error information. You must put quotation marks (" ") around the file name.
`mediaErrorFile`	Name of the file in which to save the media error information. You must put quotation marks (" ") around the file name.
`priority`	Specifies the priority that the consistency check has relative to host I/O activity. Valid entries 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`	Captures progress details, such as percent complete, and shows the information while virtual disk consistency is being repaired. To capture progress details, set this parameter to `TRUE`. To prevent capturing progress details, set this parameter to `FALSE`.

NOTE: The starting logical block address and the ending logical block address are useful for very large single-virtual disk LUNs. Running a virtual disk consistency check on a very large single-virtual disk 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 virtual disk consistency check takes to complete.
For a large virtual disk, you can set the priority to high without affecting the I/O.

If you observe a consistency mismatch MEL event, do not use startingLBA and endingLBA unless advised by Dell Support.
