Hey DPK: Are you stil having issues with ECC & the cert. If so, kindly open a service request and refernce the following KB 466555 . the EMC TSE  can help you with this.  Thanks Tim
After installing the XMS GUI for ExtremIO I can no longer bring up ECC due to a CertificateExpireException.  During the install of the GUI it does ask about installing a new root CA and the timing coincides.  Tried from another system that doesn't have the XMS GUI installed and it gets the same error.  Also tried from the server running ECC and got the same error. I'm trying to decommission the DMX3-950 and this isn't helping. Error: The EMC ControlCenter server on host mtrecc01 is unreachable. SSL HandshakeException: java.security.cert.CertificateExpiredException:NotAfter: Fri Dec 04 14:30:32 EST 2015  Thanx
Cannot reach ECC, CertificateExpireException
