Non cluster aware file sharing protocols

Services for Macintosh (SFM), File and Print Services for NetWare, HTTP file sharing protocols are

not cluster aware and will experience service interruption if installed on a clustered resource during

failover events of the resource. Service interruptions will be similar to those experienced during a

server outage. Data that has not been saved to disk prior to the outage will experience data loss. In

the case of SFM, it is not supported because SFM maintains state information in memory. Specifically,

the Macintosh volume index is located in paged pool memory. Using SFM in clustered mode is not

supported and may result in data loss similar in nature to a downed server should the resource it is

based on fails over to the opposing node.

Adding new storage to a cluster

Present the new storage to one node in the cluster. This can be accomplished through selective storage

presentation or through SAN zoning.

The tasks described below are used to add storage to a cluster. See the online help for clustering for

additional details.

Creating physical disk resources

A physical disk resource must reside within a cluster group. An existing cluster group can be used or

a new cluster group must be created. For information on creating disk resources, see the cluster online

help topic Physical Disk resource type.

NOTE:

• Physical disk resources usually do not have any dependencies set.

• In multi-node clusters it is necessary to specify the node to move the group to. When a cluster

group is moved to another node, all resources in that group are moved.

• When a physical disk resource is owned by a node, the disk appears as an unknown, unreadable

disk to all other cluster nodes. This is a normal condition. When the physical disk resource moves

to another node, the disk resource then becomes readable.

Creating file share resources

To create a file share resource, see two clustering online help topics:

• Create a cluster-managed file share

• Using a server cluster with large numbers of file shares

NOTE:

• A file share resource must reside in the same cluster group as the physical disk resource it will

reside on.

• The physical disk resource specified in this step must reside in the same cluster group as specified

in the beginning of this wizard.
