Setting Up the iSNS Administrative Settings

This section provides the procedures for changing the default administrative settings of the iSNS service and for starting the iSNS daemon. If you change a setting after the iSNS server has been started, you need to refresh the iSNS server. If you change the data store location, you need to restart the iSNS server.

The following tasks are described in this section:

• How to Install the iSNS Server Package

• How to Set Notifications for Changes in Server State

• How to Set the Number of Retries for Client Inquiries

• How to Specify the Data Store Location

For more details about these operations, see the isns(1M) man page.

How to Install the iSNS Server Package

Install the iSNS server package and start the iSNS service.

1. Become an administrator.
2. Install the iSNS server package.

   # pkg install service/storage/isns

3. Enable the iSNS service.

   # svcadm enable isns_server

4. Verify that the service is running.

   # svcs svc:/network/isns_server:default
   STATE          STIME    FMRI
   online         16:10:49 svc:/network/isns_server:default

How to Set Notifications for Changes in Server State

By default, all clients are notified when the iSNS server is not available. To disable these notifications, change the Management_SCNs_Enabled property.

1. Use the following profiles to obtain the authorizations needed for managing the iSNS service:

   • solaris.isnsmgr.write

   • solaris.smf.manage.isns

   • solaris.smf.value.isns

   For more information about roles, see Chapter 3, Assigning Rights in Oracle Solaris, in Securing Users and Processes in Oracle Solaris 11.2 .

2. Use the svccfg command to disable the property:

   # svccfg -s svc:/network/isns_server setprop config/Management_SCN_Enabled=false

3. Reload the server configuration:

   # svcadm refresh svc:/network/isns_server

How to Set the Number of Retries for Client Inquiries

The default number of retries is 3. If the server does not get a response to three inquiries, it registers that client as unavailable. To change the number of retries, change the value of the ESI Retry Threshold property.

1. Use the following profiles to obtain the authorizations needed for managing the iSNS service:

   • solaris.isnsmgr.write

   • solaris.smf.manage.isns

   • solaris.smf.value.isns

   For more information about roles, see Chapter 3, Assigning Rights in Oracle Solaris, in Securing Users and Processes in Oracle Solaris 11.2 .

2. Use the svccfg command to change the property to, for example, 6 retries:

   # svccfg -s svc:/network/isns_server setprop config/ESI_retry_threshold_count=6

3. Reload the server configuration:

   # svcadm refresh svc:/network/isns_server

How to Specify the Data Store Location

The default location and name for the file that contains the client data is /etc/isns/isnsdata.xml If you have a complex network environment that includes one or more backup iSNS servers, the data store must reside in a common location so that all servers can use it. Use the data_store_location property to specify the new location. You can also change the name of the file.

1. Use the following profiles to obtain the authorizations needed for managing the iSNS service:

   • solaris.isnsmgr.write

   • solaris.smf.manage.isns

   • solaris.smf.value.isns

   For more information about roles, see Chapter 3, Assigning Rights in Oracle Solaris, in Securing Users and Processes in Oracle Solaris 11.2 .

2. Use the svccfg command to change the location to, for example, /etc/isns2/isns_data.xml:

   # svccfg -s svc:/network/isns_server setprop config/data_store_location="/etc/isns2/isns_data.xml"

3. If you change the data store location after the server has been enabled, you must restart the server:

   # svcadm restart svc:/network/isns_server
