Detection error on Legacy mode

[evangaever]

Every time I reboot my MCS7825I4-K9-CMD1, I get the error : "Detedtion error on Legacy mode : The hardware you are using is not supported for this product. Hardware-check results: HW type [Vendor-Product] NOT SUPPORTED"

When select "Continue" the server finaliy starts. The server now runs on 7.1.3.30000-1 but I want to upgrade to 8.6.2. This upgrade fails on the same error. How can I fix this?

You are perhaps falling short of minimum required hardware resources for installing CUCM 8.6. This MCS model is

Supported, but note that Cisco Unified Communications Manager 5.0 and later require or recommend (depending on server model and software release) minimum memory and disk size as described in the table below. For Cisco Unified Communications Manager 8.0(3) and above, it is strongly recommended to upgrade to minimum 4GB RAM and 146GB disk drive; whether this is necessary for your deployment is design-dependent and depends on call volume, installed locales, dial plans, phone firmware loads, music files, etc. Use

http://www.cisco.com/go/swonly to get supported memory and disk part numbers.

I have 4GB ram and a 240GB disk so the hardware is fine.

Then you are mostly hitting a bug http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCts62097

You might be onto something there. I did use the "ciscocm.refresh_upgrade_v1.0.cop.sgn" as described in the bug. Is there a way to remove it again? I want to avoid a fresh install as I will need to rebuild my configuration in that case.

I am affraid, there is no way . I recommend taking Cisco TAC's opinion on that to see if they can rescue with their root access ( just a hopeful guess )
