When you configure a Network Appliance NAS device, you must meet the following requirements.
Allow HTTP administrative access.
Sun Cluster uses the HTTP administrative access to support fencing. Sun Cluster automatically removes file system write permission for a node that has left the cluster, and grants file system write permission for a node that has just joined the cluster. These actions ensure that a node that departed the cluster can no longer modify data. You must have the administrator login and password. You need these items when you are configuring the device in the cluster.
Cluster nodes must be configured with Solaris Internet Protocol Multipathing (IPMP).
See IP Network Multipathing Administration Guide for details on configuring IPMP.
Ensure that the SUNWzlib package is available on your cluster.
The Network Appliance NAS device requires the SUNWzlib package to run on Sun Cluster. If you installed the End User Solaris Software Group on your cluster, you must add the SUNWzlib package using the pkgadd command.
# pkgadd SUNWzlib |
When exporting Network Appliance NAS directories for use with the cluster, you must use the form rw=nodename1;nodename2 to specify access to the directories. You make these entries in the exports file on the NAS device.
