VMware Backup Proxy host issue

[mrtba]

Good afternoon everyone,

I currently have an open ticket with Symantec on this but I'm awaiting thier response, in the meantime I would like to see if anyone has experienced this issue.

Environment:

Master Server: 7.6.0.3 NBU

Client: 7.6.0.3 (Backup Proxy Host)

ESXi v 5.5 update 2

vCenter 5.5 Update 2

I currently recieve an 135 error "VMware credential validation failed." message while trying to validate the credentials to this particular backup proxy host.  I have 17 other backup proxy hosts backing up just fine.  My normal slew of tricks to get this to work isn't working...  DNS seems fine, I can resolve the FQDN and the host name itself from both the proxy server and the master.  I turned up logginng and and I see this in the bpvmutil log.

11:34:16.068 [2752.2112] <2> bprd_read_text_file: Received status 131
11:34:16.068 [2752.2112] <2> bpVMutil main: Unable to get server credentials
11:34:16.068 [2752.2112] <2> bpVMutil main: EXIT STATUS 135: client is not validated to perform the requested operation

I also see this in the bpcd log

11:34:16.068 [2680.1800] <2> run_VMutil_cmd: exit code for the process is h_errno = 135 - An attempt was made to use a JOIN or SUBST command on a drive that has already been substituted.

Any and all help is greatly appreciated.  If you want access to the case number please let me know.

Hi Tim,

Few things to verify

Ensure the Virtual Center Server and VM Backup/Access Host servers are added to the Additional Servers and Media Servers windows for the Master Server in the NetBackup Administration Console:

Host Properties > Master Servers > master server > Servers

Also check if your backup host is not multihomed.

Check out this note (allthough its from 7.5) http://www.symantec.com/docs/TECH199788

Riaan,

Thank you for your prompt reply, yes the server is in both additonal servers and media servers from the master server host properties.  I saw that TechDoc already and I confirmed that I'm not affected by it.  I checked the variables and I'm also not multihomed.

Check your bprd log, that would usually tell you / log why a server isn't allowed to do something. Maybe there is a clue.

As a matter of interest - which OS on the backup host?

[RiaanBadenhorst]

Oh, one more thing you can try is. run nbemmcmd -listhosts and see if your backup host is listed (as a virtual_machine). If it is, remove is with -deletehost, then try and add it again via the GUI.
