Rebooting Multiple Virtual Desktop Infrastructure (VDI) Nodes Breaks the Sun Ray Fail Over Group (FOG) (Doc ID 1369538.1)

Last updated on OCTOBER 14, 2014

Applies to:

Oracle Virtual Desktop Infrastructure - Version 3.3 to 3.5.1 [Release 3.0]
Sun Ray Software - Version SRS 5.2.1 to SRS 5.4.3 [Release 5.0]
Information in this document applies to any platform.

Symptoms

In a Virtual Desktop Infrastructure (VDI) cluster, two of the Virtual Desktop Infrastructure servers are also bound together in a Sun Ray Software (SRS) Fail Over Group (FOG).  After a reboot of both servers, the FOG between them has been broken. Server 1 shows Server 2 as down and vice versa.

In this state, it is possible to ping between both servers and there are no firewall rules on either that would cause communication issues. Both are also on the same subnet. Below is an example of the utreplica and utgstatus information from each server:

[root@server1 ~]# utreplica -l

Sun Ray Server Software 4.3
Administration Failover Configuration

server1 is a primary server for:
server2.vdi1.com

[root@server1 ~]# utgstatus
hostflags interface flags
10.1.0.0/32
------- -------------------
server1 TN 10.1.2.3 UA-
server2 TN 10.1.2.4 -A-


[root@server2 ~]# utreplica -l

Sun Ray Server Software 4.3
Administration Failover Configuration

server2 is a secondary server
The primary server is: server1.vdi1.com

[root@server2 ~]# utgstatus
hostflags interface flags
10.1.0.0/32
------- -------------------
server2 TN 10.1.2.4 UA-
server1 TN 10.1.2.3 -A-
