This article explains how to modify the NSIP on a SDX VPX instance.

Background

User has already provisioned a VPX instance with NSIP on SDX and later decides to change the NSIP of the instance. To do this, the user had chosen “config ns” utility on instance and successfully modified and verified accessing through SSH. However, with this change, SDX SVM was not able to communicate with instance and the status was shown in “Red” from SVM GUI.

When creating Instances on SDX, all the parameters related to VPX instance will be stored in XenServer database. The reason for the preceding behavior is when changing NSIP from instance, XenServer database will not get updated.

Instructions

To update XenServer database, issue the command xe vm-list to get the UUID of the VPX instance:

[root@netscaler-sdx ~]# xe vm-param-set uuid=f1163ed7-4b0d-7796-b9b2-6d96e171bc5d xenstore-data:vm-data/ip=172.16.1.1
[root@netscaler-sdx ~]# xe vm-param-set uuid=f1163ed7-4b0d-7796-b9b2-6d96e171bc5d xenstore-data:vm-data/netmask=255.255.255.0
[root@netscaler-sdx ~]# xe vm-param-set uuid=f1163ed7-4b0d-7796-b9b2-6d96e171bc5d xenstore-data:vm-data/gateway=172.16.1.2
