Single Instance Storage - HP X1000 System User's Manual

Script execution
You can configure ADLDS by executing the nfs-adam-config.js script that is located in the
c:\hpnas\components\ADLDS directory. Executing the script with no command line options will display
a help dialog. The following is a typical command line:
nfs-adam-config.js /passwd:<password file> /group:<group file> /
userpassword:<password>
where:
• <password file> = path to UNIX password file
• <group file> = path to UNIX group file
• <log file> = path to log file containing the results of the script execution
• <password> = the Windows password assigned to all imported users
Note that the script execution command line example is a single command; each / character represents
the beginning of a new parameter.
Verifying script execution
After the script is successfully executed, the users in the password file are listed as users on the storage
system and the groups are added. You can verify this with Server Manager:
1. Click Start, right click Computer, and then select Manage.
2. Expand the Configuration and Local Users and Groups nodes.
The imported users and groups are listed in the Users and Groups folders, respectively. If there are
errors, the log file (if specified) contains useful information to help debug problems. Note any error
messages when running the script. Any errors in importing users will be noted in the output.
NOTE:
When UNIX groups are imported, the associated UNIX users are not bound to the imported groups.
To include a user in an imported group, you must manually add the users to the group.
Shared access example
Because the imported users are now Windows users, access control for volumes (drives), folders, and
files can be controlled as if the users were local Windows users. Consider the scenario in which a
folder has subfolders that contain individual users' private files. In addition, a public folder exists for
everyone to read files from. Some users utilize NFS to access their data and some users utilize SMB
(CIFS) to access their files. To control access, create a share for the top level folder and allow everyone
full control access to the share (use the Everyone group). For each user folder, configure the security
settings to allow only that user read-write access. Some users will be imported users and some will
be native Windows users. For the public folder, enable all users read-only access.

Single Instance Storage

The Single Instance Storage (SIS) feature reduces the amount of space that is used to store data on a
volume. SIS does this by replacing duplicate files with logical links that point to a single copy of the
file in the SIS Common Store, which is a hidden folder that is located in the root directory of the
volume.
