How to Remove an Oracle ZFS Storage Appliance NAS Device From a Cluster

Language:

Before You Begin

This procedure relies on the following assumptions:

Your cluster is operating.
You have prepared the cluster by performing the steps in How to Prepare the Cluster for Oracle ZFS Storage Appliance NAS Device Maintenance.
You have removed any device directories from the cluster by performing the steps in How to Remove Oracle ZFS Storage Appliance Directories and Projects and From a Cluster.

Note - When you remove the device from cluster configuration, the data on the device is not available to the cluster. Ensure that other shared storage in the cluster can continue to serve the data when the Oracle ZFS Storage Appliance NAS device is removed. When the device is removed, change the following items in the cluster configuration:

Change the NFS file system entries in the /etc/vfstab file for that device, and unconfigure any SUNW.ScalMountPoint resources.
Reconfigure applications or data services with dependencies on these file systems to use other storage devices, or remove them from the cluster.

You can also remove an Oracle ZFS Storage Appliance using the Oracle Solaris Cluster Manager GUI. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager in Oracle Solaris Cluster System Administration Guide .

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.

Remove the device.
- Perform this command from any cluster node:
```
# clnasdevice remove myfiler
```
  myfiler
  Enter the name of the Oracle ZFS Storage Appliance NAS device that you are removing.
  
  For more information about the clnasdevice command, see the clnasdevice(1CL) man page.
- If you want to remove a NAS device from a zone cluster but you need to issue the command from the global zone, use the clnasdevice command with the –Z option:
```
# clnasdevice remove -Z zcname myfiler
```
  zcname
  Enter the name of the zone cluster where the Oracle ZFS Storage Appliance NAS device is being removed.
Confirm that the device has been removed from the cluster.
- Perform this command from any cluster node:
```
# clnasdevice list
```
- If you want to check the NAS device for a zone cluster but you need to issue the command from the global zone, use the clnasdevice command with the –Z option:
```
# clnasdevice list -Z zcname
```
Note - You can also perform zone cluster-related commands inside the zone cluster by omitting the –Z option. For more information about the clnasdevice command, see the clnasdevice(1CL) man page.
