| Option | Description |

Compares all files and their extended attribute names. |

Compares files with all or some tag names specified in the |

Specifies the directory where the primary file system is mounted. |

|
Specifies the directory where the standby file system is mounted. |
The acfsutil repl compare command verifies all or part of the primary mount point has been replicated to the standby mount point. The standby mount point must be mounted locally for comparison. Best results are obtained when the primary file system is changing as little as possible.
The -a option is typically used when no tag names were specified during the acfsutil repl init operation. The -a option compares all files on the primary file system against those on the standby file system. The -a option also tests for extra files on the standby file system that do not exist on the primary.
The -t option is used when tags were specified during the acfsutil repl init operation. The -t operation locates all file names on the primary file system with the specified tag names and compares them to the corresponding files on the standby. The -t option takes as arguments either all option or a comma-delimited list of tag names. If the -t option is used with all, then all tag names supplied during the acfsutil repl init operation are selected. Otherwise, any specified tag names must exactly match a tag name supplied during the acfsutil repl init operation. The -t option also tests for extra files on the standby file system that do not have an associated tag name that was specified during the acfsutil repl init operation. You can use the acfsutil repl info -c option to determine which tags were specified during the acfsutil repl init operation.
If neither the -a nor -t option is provided, a primary to standby file comparison is done without testing tag names nor extended attributes.
If NFS is used to mount the standby file system locally, the standby cannot be checked for matching tag names and extended attributes due to limitations in the NFS protocol.
