Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

■ Coordinator disks cannot be the special devices that array vendors use. For
example, you cannot use EMC gatekeeper devices as coordinator disks.
CP server requirements
Storage Foundation Cluster File System 5.1SP1 clusters (application clusters)
support CP servers which are hosted on the following VCS and SFHA versions:
■ VCS 5.1 or 5.1SP1 single-node cluster
CP server requires LLT and GAB to be configured on the single-node VCS
cluster that hosts CP server. This requirement also applies to any single-node
application cluster that uses server-based fencing.
■ SFHA 5.1 or 5.1SP1 cluster
Warning: Before you upgrade CP server nodes to use VCS or SFHA 5.1SP1, you
must upgrade all the application clusters that use this CP server to version 5.1SP1.
Application clusters at version 5.1 cannot communicate with CP server that runs
VCS or SFHA 5.1 SP1.
Make sure that you meet the basic hardware requirements for the VCS/SFHA
cluster to host the CP server.
See the Veritas Cluster Server Installation Guide or the Veritas Storage Foundation
High Availability Installation Guide.
Note: While Symantec recommends at least three coordination points for fencing,
a single CP server as coordination point is a supported server-based fencing
configuration. Such single CP server fencing configuration requires that the
coordination point be a highly available CP server that is hosted on an SFHA
cluster.
Make sure you meet the following additional CP server requirements which are
covered in this section before you install and configure CP server:
■ Hardware requirements
■ Operating system requirements
■ Networking requirements (and recommendations)
■ Security requirements
Table 3-1 lists additional requirements for hosting the CP server.
