   - Rcopy Get Modified Tracks - Enable or disables the calculation of modified tracks. Select TRUE or FALSE(default value) from the drop-down menu.
   - RDF Check R2 Not Writable - Verifies that the R2 devices are not writable by the host for the createpair operations other than createpair -invalidate [R1|R2]. Select ENABLE or DISABLE (default value) from the drop-down menu.
   - RDF Createpair Larger R2 - Select ENABLE(default value) or DISABLE from the drop-down menu.
   - RDF Read/Write Disable R2 - Enabling this option causes the R2 device to be set to read/write disabled, or not-ready, on the RA during establish, restore, failback, or createpair-establish operations. Select ENABLE or DISABLE (default value) from the drop-down menu.
   - SNAP Count Modified Tracks - Sets snap to return a count of the changed tracks, this option is ignored when the request is made remotely. Select TRUE or FALSE(default value) from the drop-down menu.
   - TimeFinder Count Modified Tracks - Sets TimeFinder to return a count of the changed tracks. This option is ignored when the request is made remotely. Select TRUE or FALSE(default value) from the drop-down menu.
   - Use Access ID - This option applies to Symmetrix Access Control. It specifies whether to use the access ID generated on client or server. Used only on the server side during client/server operations. Select CLIENT, the client access ID is used for every command performed. If a client access ID is not available the command fails. Select SERVER (default setting), the server access ID is used for every command performed. Select ANY, if the client access ID is available it is used for every command performed. If it is not available, and then the server access ID is used.
5. Click Save to save changes, click Reset to reset the values to their defaults.
6. Select Service Configuration from the left panel to view the services.

   The following properties display for Global Name Services:

   - Log Level - Specifies a severity-based control over logging volume. Select error, info, debug, verbose, or warning(default setting) from the drop-down menu.
   - Logfile Retention - Specifies the number of days logs are retained. Select the number of days, the default setting is 3 days.
   - GNS Device Poll Interval - Specifies how frequently storgnsd polls for changes that are made to groups from other hosts. The default value is 15 s.
   - GNS PPATH Poll Interval - Specifies how frequently storgnsd checks to see whether PowerPath or SRDF consistency group updates are necessary. The default value is 60 s.
   - GNS Remote Mirror - Specifies whether storgnsd should automatically mirror RDF1 and RDF2 type DG and CG group definitions for use on remote (SRDF) storage systems. Select enable or disable (default value) from the drop-down menu.
   - GNS Remote Array Update Interval - Specifies how frequently storgnsd should attempt to propagate device groups over to remote (SRDF) storage systems. The default value is 60 s.

   The following properties display for Remote Client/Server Services:

   - Log Level - Specifies a severity-based control over logging volume. Select error, info (default setting), debug, verbose, or warning from the drop-down menu.
   - Logfile Retention - Specifies the number of days logs are retained. Select the number of days, the default setting is 3 days.
   - Log Filter - Specifies category-based control over logging volume, by selecting which types of storsrvd numbered log messages are recorded in the storsrvd log files. Specifies category-based control over logging volume, by selecting which types of storsrvd numbered log messages are recorded in the storsrvd log files. Each log message that is issued by storsrvd is associated with a category, expressed by the filter names shown below. The numbered messages appear in the storsrvd log files. Numbered messages that are issued by storsrvd use a message identifier that precedes the message text: ANR0001I SYMAPI server ready to accept SECURE connections. The value to be specified for LOG_FILTER consists of a series of keywords that are shown below separated by a comma (,) or plus signs {+). SERVER: Records high-level events of the server: initialization, termination, and other events that are not directly related to a SYMAPI session. SESSION: Records arrival and termination of SYMAPI sessions. APIREQ: Records arrival and completion of SYMAPI function requests. CONTROLS: Records activity during execution of management requests from stordaemon or the system console in the z/OS environment. If LOG_FILTER specifies either SESSION+APIREQ, it is most useful to set LOG_LEVEL to info. There default for this option is SESSION+APIREQ.
   - Client certificate verification level - This option controls the verification of the client certificate by the server. Select MUSTVERIFY to indicates that the server only accepts communications from a version of the client that can send a certificate to be verified. Select NOVERIFY (default value) to indicate that the server does not verify the client certificate. Select VERIFY to indicate that the server verifies a client certificate if the version of the client can send a certificate. This option is ignored if secure communications are not established.
   - Maximum SYMAPI sessions to the server - This option takes precedence over the options file option SYMAPI_MAX_CLIENTS. This specifies the global high-water mark of all sessions that are allowed by the server, without respect to source host or user. When the next new session causes the current number of sessions to exceed this number, it is refused. Enter a value between 0 and 100, 100 is the default value.
   - Maximum SYMAPI sessions per user to the server - This option specifies the high-water mark for concurrent sessions from any specific user. When the next new session from the source user causes the current number of sessions from that user to exceed this number, the session is refused. When setting a numeric value, select MAX_SESSIONS. If it is set greater than MAX_SESSIONS, and then the maximum number of sessions for any specific user is restricted to MAX_SESSIONS. If the value is set to NOLIMIT(default value), and then user sessions are only restricted by the MAX_SESSIONS value.
   - Wildcards in Common Name - Specifies if wildcards are allowed in the Common Name in client certificates. Select ENABLE or DISABLE(default value) from the drop-down menu.
7. Click Save to save change, click Reset to reset the values to their defaults.
8. Select Symavoid from the left panel to view the services.
   Available Systems and Symavoid Systems are listed. Add systems from Available Systems to Symavoid Systems or from Symavoid Systems to Available Systems.
9. Select Nethost configuration from the left panel to view and configure the nethost.
   Enter Node Name and User.
10. Click Configure to update the Nethost List.
