When you use a Network Appliance NAS device, the following are always required:
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
You must have the administrator login and password. You need these items when you are configuring the device in the cluster.
When exporting 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.
