vxverify
vxverify is a command that determines if there are any differences between plexes of mirrored volumes. This command compares the volumes on a block by block basis. Blocks that do not match are reported in the output.
Note:
For RAID-5 volumes, vxverify also checks the integrity of the parity of the volumes.
Typing the following sequence brings up a description of its syntax:
vxverify -?
vxverify [-v] [-p] [-m <f|x>] [-d <n|all>] <DynamicDiskGroupName> <Volume Name>[[offset] length]
The following attributes apply:
-v | Enables verbose output. This specifies that in addition to any blocks that do not match, the output includes the mirror volume name, block number, and number of blocks being compared. |
-p | Enables the utility to process a partial plex for debugging purposes. |
-m | Used to specify the mode that should be used to compare the volumes on a block by block basis. |
f|x | Determines the mode for comparing the mirrored volumes.
|
-d | Enables the utility to dump mismatched blocks. |
n|all | Specifies the number of mismatched blocks to dump.
|
<DynamicDiskGroupName> | Specifies the dynamic disk group of the volume. Note: The name of the disk group is case-sensitive. |
<Volume Name> | Specifies the volume to process. |
offset | Specifies the offset for comparison. Offset is specified as a number of blocks. |
length | Specifies the length for comparison. Length is specified as a number of blocks. Note: If no length is specified, then the entire volume is compared. |
Example
vxverify -g Accounting test
This command performs a comparison of the volume test of the disk group Accounting and its mirrors.
