PowerFlex 3.x Failed to approve LIA certificate Number of Trusted IPs exceeds MAX_TRUSTED_IPS [6]

In the scaleIO.log file on the Gateway we see the following errors during the installation when it fails:-

Looking at the LIA logs trace.0 in the LIA folder we see the following error:-

30/07 09:08:50.071281 0x1b4aeb0:liaNet_Init:01683: Number of Trusted IPs exceeds MAX_TRUSTED_IPS [6] - check config file , ignore rest of IP's

As per the Deployment Guide:-
To restrict which Gateway IP addresses can access the LIA, add those IP addresses to this line in the conf.txt file:
lia_trusted_ips=<IP_ADDRESS_1>,<IP_ADDRESS_2>

To set this during LIA installation, set the TRUSTED_IPS environment variable. For example:
TRUSTED_IPS=IP1,IP2 rpm -i lia.rpm

Deployment guide does not mention how many IPs you can use in the above list of TRUSTED_IPS. 

Using more than 6 IPs
