Celerra Network Server Command Reference Manual
The nas Commands
-xtend <fs_name> <volume_name>
Adds the specified volume to the mounted file system.
-xtend <fs_name> size=<integer>[T|G|M|%]
Adds the volume as specified by its desired size to the file system.
Enter an integer within the range of 1 to 1024, then specify T for
terabytes, G for gigabytes (default), M for megabytes, or enter an
integer representing the percentage of a file system’s size followed by
the percent sign. The extended volume added to the file system by
the system will have a size equal to or greater than the total size
specified.
CAUTION
!
When executing this command, to reduce time consumption,
extends should be performed incrementally, using like volumes.
[pool=<pool>]
Applies the specified storage pool rule set to the volume that
has been added to the mounted file system.
Note: The storage pool is a rule set that contains automatically
created volumes and defines the type of disk volumes used and how
they are aggregated.
[storage=<system_name>]
Specifies the storage system on which the checkpoint resides.
If a storage system is not specified, the default storage system
is the one on which the file system resides. If the file system
spans multiple storage systems, the default is to use all the
storage systems on which the file system resides. Use
nas_storage -list
to obtain attached storage system names.
[-option <options>]
Specifies the following comma-separated option(s):
slice= {y|n}
Specifies whether the disk volumes used by the file system may
be shared with other file systems using a slice. The slice=y option
allows the file system to share disk volumes with other file
systems. The slice=n option gives the new file system exclusive
access to the disk volumes it uses, and is relevant when using
TimeFinder/FS.
