Chapter 4 Managing Clients and Users 59
Mounting a Volume on a Client
A user who is logged in to a client computer can’t mount a SAN volume. A SAN
administrator must use Xsan Admin to mount the volume on the client computer.
To mount an Xsan volume on a client:
1 Open Xsan Admin, select the volume in the SAN Components list, and click Clients.
2 Select the client computer in the list.
3 Click Mount Read & Write.
To prevent the client from modifying the volume, click Mount Read Only after you click
Mount Read & Write.
You only need to mount an Xsan volume on a client once. The volume remains
mounted, even if the user logs out or the client computer is restarted, until you
unmount it or the user on the client unmounts it.
From the Command Line
You can also mount a volume on a client using the
mount command in Terminal. For
more information, see the mount man page or “Mounting an Xsan Volume” on
page 95.
Controlling Client and User Access
You can control access to information on SAN volumes at several levels:
• You can restrict user access to folders on a volume by specifying owner, group, and
general access permissions (folder level).
• You can unmount a SAN volume from selected client computers (volume level).
• You can restrict a client computer to read-only access to a volume (volume level).
• You can remove a client from a SAN (SAN level).
Controlling Access to Folders on Volumes
To restrict user access to specific folders on a SAN volume, assign access permissions to
the folder.
To assign folder access permissions:
1 Make sure the volume is started and mounted on the controller.
To start a volume, select it and click Start Volume. To mount it, select the volume, click
Clients, select the controller, and click Mount Read & Write.
2 In Xsan Admin, select the volume that contains the folder, and click Affinities.
Volumes are listed in the SAN Components list under the SAN to which they belong.
3 Select the folder in the list and specify permissions at the bottom of the window.
4 Click Save.
