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.
When setting up your NAS device:
Create a volume on each Network Appliance NAS device for storing Oracle database files, namely:
Online redo log files
Archived redo log files
The directory that contains Oracle data files for the cluster
The Oracle home directory that is to be mounted on each node
Ensure that the volume is exported without the nosuid option.
If you boot devices in the wrong order, your nodes cannot find the quorum device. If a node should fail in this situation, your cluster might be unable to remain in service. If your cluster experiences these failures, you must either reboot the entire cluster or remove the NAS quorum device and add it again.
A cluster can use a NAS device for only a single quorum device.
You can configure other shared storage if you need additional quorum devices. Additional clusters using the same NAS device can use separate LUNs on that device as their quorum devices.
