NickA99: THANK YOU!
I had an unclearable "Host IPMI System Event Log status" alarm on a Fujitsu Primergy RX200 S7. Clearing its IPMI SEL content via the iRMC S3 (lights-out management) card did nothing, and I couldn't see a Hardware Status tab. And using an XP VM as a thick client. I'm also using vCSA for vCenter, so I made a backup of /usr/lib/vmware-vpx/tomcat/conf/server.xml into /root and modified the cipher line with your text. After rebooting, HARDWARE STATUS!
Which only got me one step further in my problem set, but it's still a breakthrough
