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.
