Error to upgrade ESXi 5.5 to 6 U1 with update manager

[SirHaschke]

Hello,

i try to upgrade my ESXi Server from 5.5 to 6 with update Manager.
I get this error:

The host can't reconnect.

A manually update works fine.

Why can't i upgrade the host with update Manager?

Thanks

Dennis

what is your vCenter version? Have you upgraded it to 6.0U1 already?

Thanks

‌yes.

[Techie01]

can you paste/upload the log file when the host tries to connect back to VC . The logs from /var/log/vmkernel and /var/log/hostd.log will be useful. Is there VSAn configured. What was the esx 5.5 version from where it was upgraded

[SirHaschke]

The logs are in the attachment.

VSAN is not configured.

Version of ESXi was 5.5 U2 (VMware-ESXi-5.5.0-Update2-2068190-HP-5.77.3-Nov2014.iso).

Now i try the update with "VMware-VMvisor-Installer-6.0.0.update01-3029758.x86_64.iso".
Manually works fine only with UM is the problem.

From the screenshot, the issue occured at 13:02 on 21/09. The logs uploaded are from 2015-09-22T02:29: . I am not able to find any relevant information from the logs

[Techie01]

The older logs will be in /var/run directory

[SirHaschke]

In var/run i cant find any log files.

Only conf and pid files.

Before i uploaded the files i try manually reconnect the Server.
