Configuration Guide for Disaster Recovery for Dell
Introduction
The Configuration section covers procedures required to set up, secure, and manage your Eyeglass environment for operational readiness and disaster recovery.
User Roles
This section walks through the setup and requirements for role-based logins using SMB system zone authentication, including how to create roles, assign permissions, and validate access via AD. Learn how to use AD groups for fast role assignment and test permissions for secure delegated access.
Two-Factor Authentication
Two-Factor Authentication (2FA) enhances login security for Cyberstorage for Dell Eyeglass by requiring users to verify their identity using a second authentication factor. Using Time-based One-Time Password (TOTP) with Google Authenticator, 2FA significantly reduces the risk of unauthorized access from compromised credentials.
This section covers how to enable and configure 2FA, manage user enrollment, understand the login workflow, and troubleshoot common issues. You'll also learn about security considerations, audit logging, and best practices for deploying 2FA in enterprise environments.
Eyeglass Jobs
Eyeglass jobs are the automation engine behind replication, failover, quota syncing, readiness checks, and other operational tasks.
This section covers the types of jobs created by Eyeglass, including Configuration Replication, DFS mode, Quota, and Failover jobs. You'll also learn how to manage them using bulk actions, set job types and modes, and troubleshoot unconfigured or failing jobs.
Job Types
Monitoring and Alerts
Configure email and syslog notifications so your team learns about job failures, alarms, and other events that affect disaster recovery readiness as soon as they happen.
Configuration Replication
Eyeglass Configuration Replication ensures that your disaster recovery environment mirrors the data access configuration of your production environment. It syncs SMB shares, NFS exports, quotas, snapshots, deduplication settings, and more across clusters, using existing SyncIQ replication paths.
Use this document to learn how replication jobs work, what metadata is transferred, how to prepare the DR environment, and how to enable or disable replication at scale. You'll also find platform-specific replication behavior and troubleshooting guidance for common sync issues.
Data and Config Migration
Data and Config Migration moves data and its associated configuration (SMB shares, NFS exports, quotas, NFS aliases) between Access Zones or between clusters — for one-time or scheduled migration projects such as restructuring Access Zones, consolidating clusters, or preparing for cutover to a new environment. This is distinct from the continuous, standing-DR sync performed by Configuration Replication above.
OpenSUSE OS Upgrade from 15.6 to 16.0
This guide provides comprehensive instructions for upgrading OpenSUSE from version 15.6 to 16.0 on Eyeglass and ECA virtual machines. The upgrade process includes pre-upgrade preparation, AppArmor package management, network reconfiguration, and post-upgrade service validation.
Learn how to safely perform the OS upgrade while maintaining system stability, handle network configuration changes, restore configuration files, and troubleshoot common issues that may arise during the upgrade process.
Common Operations
Configure Cluster Delegation
Advanced Failover Modes
Dual-NIC Configuration
Configure a second network interface and static routes on the Eyeglass appliance for environments that do not allow a single NIC to reach both source and target clusters.
Changing Eyeglass UI Behavior
Adjust the Web UI auto-logout timer, disable the login page notification feed, and extend the UI API timeout for long-running operations such as Unlock My Files.
Seamless Failover
Script Engine
Automate pre-failover, unified, and post-failover host-side and third-party tasks — such as remounting NFS exports or calling APIs on external equipment — that fall outside what Eyeglass manages directly on the PowerScale OneFS clusters.
