G410 Build Failure at PSC firstboot - new install

Hi,

Does anyone have any suggestions regarding build failures on a new unit.

It has been sitting in the box (so to speak) for a while so the shipped version is 4.5.0.7.0.

3 node G410 hybrid unit - no hardware issues detected.

It fails at step 11 of the deployment tasks - the install gets to configuring the PSC for the firstboot however it never finishes, the PSC VM appears to be running however unconfigured (shows 'root password not set' and 'RPM Installation failed') as well as just 'localhost.localdom' for the hostname.

Installer log has many entries for:

[MARVIN] 2018-08-22T12:38:01:158Z  INFO c.v.m.c.s.c.a.s.i.AbstractFirstBootCloudVMAction:482 - Checking first boot status...

[MARVIN] 2018-08-22T12:38:02:986Z ERROR c.v.c.c.s.g.GuestOperationsUtil:173 - Something went wrong while running GET_DOWNLOADFILE_URL

com.sun.xml.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: Failed to authenticate with the guest operating system using the supplied credentials. Please see the server log to find more detail regarding exact cause of the failure.

I believe I have checked all the usual items such as DNS and NTP etc. and the config inputs passed validation without issue.

I have also tried (based on suggestions from elsewhere), reducing NTP and DNS down to a single IP, change the logging function to 'none'

Each time install fails I have had to reset the unit back to the start using the 4.5.0 reset script which seems to work fine but it just adds to the delays!

I'm awaiting credentials to open a case but in the meantime I thought I'd ask here to see if the issue has been seen before as its quite urgent that I get this up and running.

Thanks in advance,

Garth
