Experiencing issues with a Dell EqualLogic PS6210 array not booting after a power outage can be challenging, especially when it is out of warranty. Below, we provide a comprehensive guide to diagnose and resolve common problems associated with EqualLogic arrays that fail to power up correctly.
Troubleshooting Dell EqualLogic PS6210 Boot Issues
Dell EqualLogic arrays are robust storage solutions, but power outages can lead to issues requiring a systematic approach to troubleshooting. Here are steps and best practices to help identify and resolve such issues.
Initial Assessment
1. **Power Supply Check**: Ensure that the power supply units (PSUs) are functioning correctly. Both PSUs should have their status LEDs illuminated, indicating a proper power connection. If one PSU is faulty, replace it to see if the issue persists.
2. **Controller Status**: Observe the controller status LEDs on both controllers. If neither controller becomes active, it might indicate a hardware-level fault or configuration issue.
3. **Disk Drive Indicators**: Check the disk drive LEDs. Blinking lights often indicate activity, while persistent lights could suggest an error. Ensure that all disks are seated correctly and that there are no amber lights indicating disk failures.
Console Access and Connectivity
1. **Serial Port Access**: Verify your serial connection settings. The correct configuration is crucial; typically, EqualLogic arrays use settings such as 9600 baud rate, 8 data bits, no parity, 1 stop bit, and no flow control.
2. **Management Port**: If the serial connection is unsuccessful, inspect network connectivity to the management port. Ensure the network settings configured on your client match those expected by the management interface.
Firmware and Software Considerations
1. **Firmware Version**: If accessible, verify that the firmware is up to date, as outdated firmware could contribute to boot issues. Updates can often resolve known issues caused by power fluctuations.
2. **Dell Support Resources**: Since the array is out of warranty, access Dell’s official support documentation for firmware updates and troubleshooting guides. Dell TechDirect and the official Dell Knowledge Base are valuable resources.
Advanced Troubleshooting Steps
1. **Controller Reset**: If both controllers fail to respond, attempt to perform a reset. Before doing so, ensure that you have documented configurations and have backups if possible.
2. **Configuration and Logs**: Access any available event logs, either through a management tool or by attempting to capture console output. Look for specific error codes or messages that can guide further actions.
Preventive Measures
To prevent future boot issues, consider the following:
– **Uninterruptible Power Supply (UPS)**: Ensure the array is connected to a reliable UPS to guard against power outages.
– **Jumbo Frames and Network Settings**: Configure MTU settings to 9000 for optimal iSCSI performance and isolate storage traffic using VLANs.
– **Planned Maintenance**: Integrate firmware updates and routine checks into your maintenance schedule to mitigate unforeseen hardware failures.
