server and provides identity to the group, which is not associated with a
specific node and can be failed over to another node in the cluster. Users
access the groups using this virtual server. A virtual server can have
multiple file shares.
In the creation of a basic file share that is publicized to the network under a single
name, you must set it up to be dependent on the physical disk and network name
in the same disk group you are creating the file share in. The network name is
dependent on the IP address, so do not add that to the dependency list. You can
set the share permissions and advanced share resources also.
Users will access the cluster resources using \\<network_name>\<fileshare_name>.
Clustered file share creation example
An example of how to create a clustered file share follows. For this example,
assume that you are creating a file share in Disk Group 2.
1. Create the IP address resource:
a. Right-click Disk Group 2, and select New → Resource.
b. Enter an IP address name, for example ipaddr2, and change the resource
type to IP Address.
c. Select Run this resource in a separate Resource Monitor and click Next.
d. A list of possible owners appears, and both nodes should remain as
assigned. Click Next.
e. There are no resource dependencies on this panel, so click Next.
f. Enter your TCP/IP parameters. This will be the first virtual IP address. The
value in the Network field identifies to the system the network on which the
address is located. Click Finish to create the resource.
g. Right-click the resource and select Bring online.
2. Create the network-name resource:
a. Right-click Disk Group 2, and select New → Resource.
b. Enter the virtual server name to use (for example, NN2), select Network
Name as the resource type, and click Next.
c. Both nodes are possible owners. Click Next.
d. Add the IP address you created as a resource dependency in Step 1 and
click Next.
e. Type the virtual server name, NN2, into the Network Name Parameters field
and click Finish.
f. It takes a few moments to register the virtual server name with your name
server. After this completes, bring the resource online.
3. Create the CIFS or NFS file share resource:
a. Right-click Disk Group 2 and select New → Resource.
b. Enter a file share name (for example, FS2) and select either File Share or
NFS Share.
c. Both nodes are possible owners. Click Next.
d. Add the resource dependencies for the physical disk and network name that
the file share will use and click Next.
e. Enter the share name of FS2 and the path to the disk in this group, either
drive or subdirectory. You can then set:
v For CIFS shares properties:
– User Limit
– Permissions
