Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:




After changing the IP address and FQDN of the device server, Smarts Network Configuration Manager (Smarts NCM) cut-through is not working

Error message in java console logs for Smarts NCM environment:

ERROR com.powerup.configmgr.deviceservice.Tunnel  - Couldnt connect to 127.0.0.1:37108 through tunnel server x.x.x.x:11965
zebedee.ZBDNetworkException: cant connect to x.x.x.x:11965: java.net.ConnectException: Connection refused: connect

Environment

VMware Smart Assurance - NCM

Resolution

to resolve the issue, an update to the infradb must be made.

On the application server, do the following:

[root@lab94as cgi-bin]# . /etc/voyence.conf
[root@lab94as cgi-bin]# ./cflist.cgi > file.txt
[root@lab94as cgi-bin]# cp file.txt 6-16-2017_infradb.txt <<this is your backup copy, use the current date in the file name to easily identify.
[root@lab94as cgi-bin]# vi file.txt <<modify this file

Search for the device server IP or hostname (old name). You should see an entry similar to the following:

POP 1000 "ncm94.smrtsupport.local" NetList= RsrcList= DevList=1001,1002,1003,1004,1005,1006,1007,1008,1009,1010,1011,1012,1013,1014,1015,1016,1017,1018,1019,1020,1021,1022,1023,1024,1026,1027,1028,1029,1030,1031,1032,1033,1034,1036,1038,1039,1040,1041,1106,1044,1045 EmsList= : ADDR="10.241.215.98" AGE_DAYS=730 CLEANUP_DAYS=90 AD_ENABLE=0 AD_ARPCACHE=0 AD_DFLTROUTE=0 AD_AUTO_RESOURCE=0 AD_DEFAULT_POLL=0 SNMP_TIMEOUT=500

Using vi commands, edit the hostname and IP address values. Save the file and quit.

[root@lab94as cgi-bin]# ./cfwrite.cgi < file.txt
Status: 200 Success.

These changes will be replicated to the infradb files on each DS.

Next, log into the controldb:

[root@lab94as cgi-bin]# su - pgdba
-bash-4.1$ psql voyencedb voyence
Password for user voyence: <enter password>

To see the attached device servers, use the following statement:

voyencedb=# select * from cm_device_server;
                 device_server_id                  |   device_server_name    | device_server_idx | version
---------------------------------------------------+-------------------------+-------------------+---------
 \012\361\327y\357\011\345?4!\333\272M\001\000\000 | ncm94.smrtsupport.local |              1000 |       0
(1 row)

To modify the entry, use the following statement:

update cm_device_server SET device_server_name='<new_ds_fqdn>' WHERE device_server_idx= POP IDX ;

In this example, 

update cm_device_server SET device_server_name='ncm94NewDS.smrtsupport.local' WHERE device_server_idx= 1000 ;

voyencedb=# select * from cm_device_server;
                 device_server_id                  |   device_server_name    | device_server_idx | version
---------------------------------------------------+-------------------------+-------------------+---------
 \012\361\327y\357\011\345?4!\333\272M\001\000\000 | ncm94NewDS.smrtsupport.local |              1000 |       0
(1 row)
