Dell Unity: Kunne ikke oprette DHSM-forbindelse pga. ugyldigt CTA-serverværtsnavn

Summary: Løs problemer med oprettelse af forbindelse til Unity Distributed Hash Table Secure Manager (DHSM) (Fejlkode: 0x6720642) forårsaget af ugyldige CTA-serverværtstegn (Cloud Tiering Appliance), f.eks. understregningstegn, og sørg for gyldig formatering af værtsnavn for oprettelse af en DHSM-forbindelse. ...

Symptoms

Der kan ikke oprettes en DHSM-forbindelse mellem Unity og CTA-serveren. Denne fejl vises, når du forsøger at oprette forbindelsen fra CTA-serveren:

ACD authentication: Failed. No matching connection was found for the secondary target.  The connection will be created automatically after the first archiver run involving this primary and secondary.  If you want to verify the authentication credentials you must create a secondary connection for the primary on the control station.

Cause

URL-adressen (værtsnavnet) på CTA-serveren indeholder et ugyldigt tegn, f.eks. et understregningstegn.

Resolution

Skift værtsnavnet på CTA til et gyldigt navn. I dette tilfælde blev der opnået et gyldigt navn ved at fjerne understregningen. 

Eksempel:
Original hostname: cta01_abc.xxxxx.com

Updated hostname: cta01abc.xxxxx.com
