```

How to Display the Status of Clients

Select one of the following to display client status:
- Show the status of all clients:
```
#isnsadm list-node -v 
```
- Show the status of only the clients that are targets, that is, storage objects:
```
#isnsadm list-node -t
```

How to Remove a Client from a Discovery Domain

Use the “iSNS Server Management” RBAC profile to obtain the authorizations needed for managing the iSNS service.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

List the clients to identify the one you want to remove.

#isnsadm list-node -v
       iSCSI Name: iqn.1986-03.com.sun:01:000e0c9f10da.45173FEA.engr
          Alias: STK5320_NAS
          Type: Target
          Network Entity: SE5310
          Portal: 172.20.57.95:3260
              Portal Group: 1
          Portal: 172.20.56.95:3260
              Portal Group: 1
          DD Name: Research,Finance

The output shows the client's iSCSI name and the name of the discovery domains of which it is a member.

Remove the client from the discovery domain.

#isnsadm remove-node -d domain_name iSCSI_name

How to Remove a Discovery Domain from a Discovery Domain Set

```
Remove the discovery domain from the discovery domain set.
```
#isnsadm remove-dd set_name domain_name

How to Disable a Discovery Domain Set

Use the “iSNS Server Management” RBAC profile to obtain the authorizations needed for managing the iSNS service.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Deactivate a discovery domain set:

```
Verify that the state of the discovery domain set has changed to Disabled:
```
#isnsadm list-dd-set set_name
```

How to Remove a Discovery Domain Set

After you remove a discovery domain set, its discovery domains remain. A discovery domain must be a member of at least one discovery domain set.

Use the “iSNS Server Management” RBAC profile to obtain the authorizations needed for managing the iSNS service.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
List the discovery domain sets to identify the one you want to remove.
