IBM Hub/Switch Installation Manual page 455

For DFS, this file consists of a number of lines that describe the aggregates and the filesets that
reside on that aggregate. Each aggregate is described by a line that begins in the first column. After
the line for each aggregate are the lines that describe the filesets that reside on that aggregate. Fileset
lines begin with a TAB character. Any line that begins in column one is treated as the definition for
an aggregate.
An aggregate configuration line contains the following information:
path media fsid option migratePolicy purgePolicy stageType
and the format for a fileset configuration line is:
<TAB> ftname global local ftid gateway port
For XFS, each filesystem is listed on a single line beginning in column one. The format of this line is:
name global media option migratePolicy purgePolicy MPQueueSize \
ftid gateway port

Following is a description of the parameters for a DFS aggregate:
Path specifies the path name where DFS mounts the aggregate. Typically, this is /opt/dcelocal/var/
dfs/aggrs/aggrname, where aggrname is the name of the aggregate.
Media specifies the device file for the aggregate. Typically, this is /dev/aggrname, where aggrname
is the name of the aggregate.
