Follow the instructions in this procedure whenever the Oracle ZFS Storage Appliance NAS device maintenance you are performing might affect the device's availability to the cluster nodes.
Before You Begin
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical.
To perform this procedure, become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization.
If you have data services using NFS file systems from the Oracle ZFS Storage Appliance, bring the data services offline and disable the resources for the applications using those file systems. On each node, ensure that no existing processes are still using any of the NFS file systems from the device.
If you have a resource of type SUNW.ScalMountPoint managing the file system, disable that resource to achieve that.
If that resource is not configured, use the Oracle Solaris umount (1M) command. If the file system cannot be unmounted because it is still busy, check for applications or processes that are still on that file system, as explained in Step 1. You can also force the unmount by using the –f option with the umount command.
