Dell VNXe3300 Secure Remote Support for VNXe Requirements and Configuration - Page 6

Configure ESRS ESRS to work. ESRS is supported in full service mode (both SPs are in service mode). If you have already enabled ESRS, the system functions as configured. If you have not enabled ESRS, you can temporarily enable it. In this latter situation, the configuration will not persist once your VNXe system has recovered to normal operation. ESRS Communication Although the VNXe can be configured with DNS disabled, access to a DNS server is required for the ESRS to work. By default your ESRS will attempt to use a configured proxy server to communicate with EMC backend systems. If the proxy server is not available, the ESRS will attempt to bypass the proxy server and communicate directly to the EMC backend systems. The ESRS service is the primary (default) method used by ConnectEMC to communicate with EMC backend systems. If ESRS is not enabled, ConnectEMC will automatically fallback to the secondary configuration and use the SMTP server, if configured. Configure ESRS Prerequisites As a prerequisite for enabling ESRS on your VNXe system, you must have an existing EMC Online Support account with Full Access support credentials (see Upgrading to Full Access privileges). Your Full Access support credentials are associated with your site ID/location which is associated with your system's serial number. Note: It can take up to 48 hours for your initial account with full access support credentials to be activated. Enable ESRS In Unisphere, you can configure ESRS support for a VNXe system in several ways: Unisphere tool Unisphere Configuration wizard Unisphere Post-upgrade wizard Description Wizard for configuring global VNXe system settings which runs when you first access the system with Unisphere. Wizard available in VNXe OE version 2.2.x or later for configuring ESRS settings which runs immediately after upgrading VNXe operating environment software. 6 EMC Secure Remote Support for VNXe Requirements and Configuration Technical Notes
