signify that the pathname was shortened. If the DETAIL or LOG options are specified
with these commands, the complete OSS pathname is displayed. Pathnames wrap to
the next line if necessary.
AutoSYNC synchronizes the following OSS disk files:

Directories

Regular files

Symbolic links

Hard links
Unlike an empty Guardian file system subvolume, an empty directory is synchronized.
To protect the destination file set from loss of integrity in case of system or component
outages, AutoSYNC performs the following steps when synchronizing a file or
directory:
1. The file or directory is first created with the destination filename plus a temporary
name extension ZASYnnnn where nnnn is a number.
2. Data is written to the file.
3. When the synchronization of the file has completed, the old destination file or
directory is deleted and the new destination file or directory is renamed to its final
name without the temporary name extension.
If a synchronization fails, AutoSYNC deletes the temporary file or directory and the old
file or directory remains in place.
Source File Set
The source file set must describe only local files. If the source file set contains a
system name (for example /E/PARIS), the system name must be the local Expand
node name.
Guardian files cannot be synchronized with their OSS pathname, that is using the /G
directory. Use the regular Guardian naming when synchronizing Guardian files.
Destination File Set
The destination file set may be either on the local system or a remote system; specify a
remote destination file set with the Expand identifier and the system name (/E/PARIS)
followed by the absolute pathname.
Unlike Guardian file sets, OSS file sets cannot specify the destination system as back
slash asterisk (\*). Specifying /E/* as the destination system for OSS files is not
supported.
