HP StorageWorks Clustered File System 3.1.1 for Linux Installation Guide (May 2006)

Chapter 4: Install HP Clustered File System 30
System Management Console can display the switch ports used by the
SAN. (The preceding window shows the text that appears for
FibreChannel switch-based fencing.)
To configure SAN switches, you will need to specify the hostnames or
IP addresses of the FibreChannel switches that are directly connected
to the nodes in the cluster. Click Add, and then specify the hostname
or IP address of the first FC switch. Repeat this procedure to specify
the remaining FC switches, including cascading switches.
2. SNMP Community String. The default SNMP community string for
Clustered File System is private. If you want to use a custom
community string, enter the appropriate value here. The SNMP
community string must be set to the same value on Clustered File
System and on the SAN switches configured above.
3. Membership Partitions. Clustered File System uses a set of
membership partitions to control access to the SAN and to store the
device naming database, which includes the global device names that
Clustered File System assigns to the SAN disks placed under its
control.
You will need to select the LUNs or disk partitions that should be used
as membership partitions.
NOTE: LUNs must already be partitioned as described in Chapter 2,
under step “6. Create LUNs or Disk Partitions for Membership
Partitions” on page 17.
Clustered File System can use either one or three membership
partitions. To ensure that a membership partition is always
available, we strongly recommend that you select three partitions.
