https://community.hpe.com/t5/proliant-servers-ml-dl-sl/cache-error/m-p/3292642#M30585 It sounds like to me that the issue is not with an array accelerator, but the processor cache accelerator, also known as tag RAM.<BR /><BR />It caches one of the two processor buses (sets of four processors).<BR /><BR />Refer to <A href="http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=PSD_EH991119_CW01" target="_blank">http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=PSD_EH991119_CW01</A> for more information.<BR /> Tue, 01 Jun 2004 20:49:37 GMT Jon Ward 2004-06-01T20:49:37Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/cache-error/m-p/3292640#M30583 I'm having the following error when booting up a compaq proliant 6000 server. Does someone have adive on this. I'm thinking it could be processor or raid card.<BR /><BR />post error 2ch220 runtime cache accelerator failure slot 1 reconfigure or replace.

Is the error in the ACU/ADU. If possible reboot the server to see if you get the error when the array controller initilizes on POST.

It was essentially the Proliant 8000 (which looked almost identically on the outside to the 6000), the 8500, and the DL760.<BR /><BR />Yet the message is almost dead on. You may want to verify the server model. Tue, 01 Jun 2004 21:16:59 GMT https://community.hpe.com/t5/proliant-servers-ml-dl-sl/cache-error/m-p/3292643#M30586 Jon Ward 2004-06-01T21:16:59Z
