If the customer chooses to continue License Manager service will never startup. Lack of License Manager on the Publisher node prevents any administrative changes being performed like adding a new phone or deleting.<br><br><br>Workaround:<br><br>Ensure all 4 drives are plugged in to the server even if they are failed/defunct drives.</div><div><br></div><div><br></div><div><br></div><div>Net result is any missing drive causes "unsupported platform". Let your Cisco account team know this is a problem. Get your TAC case attached to this to provide more evidence of customer impact. This is all a software limitation that could be overcome with sufficient motivation.</div><div><br></div><div>Otherwise, the 7825 hardware uses a rather poor implementation of RAID IMHO. Technically it is mirrored but we just do not see the same level of reliability in that platform. You are still facing a hardware failure and we must look to IBM to resolve that.</div><div><br></div><div>/wes</div><div><br></div><div><br></div><div><br><div><div>On Feb 14, 2012, at 10:43 AM, Sinisa Djokic wrote:</div><br class="Apple-interchange-newline"><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; ">hi group..<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; ">does anybody have expertise on this matter..<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; ">maybe wes or ryan have inside info..<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; ">we had a TAC case with failed HDD and problematic RAID controller in MCS-7825-I4 server running CUCM 7.1.5..<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><font size="2" face="Calibri"><span style="font-size: 11pt; ">the symptom happend when we shutdown the server in order to check what IBR FRU is on memory inside the server..we checked it and after that we powered up the server..
