This means that the email could not be sent. It is always accompanied by a more specific error.

Error in tcp_open for servername

This means that StorEdge could not open a TCP connection to the configured mail server. Possible reasons are name resolution, incorrect IP, IP unreachable due to network problem. To correct this issue, enter the mail server by IP address, and make sure the IP address is correct and reachable. The ping command from the StorEdge CLI may be helpful in this case, both by name and IP address.

Unknown code <501 Syntax error, parameters in command "MAIL From: <servername@>" unrecognized or missing.

The key here is the “from” address ending in the “@” character. The SMTP server usually refuses email from StorEdge unless a DNS domain is configured, dependent on mail server configuration. This is true whether you are using DNS or not.

Unknown code <501 This MTA is configured NOT to relay message from [servername] to [domain.com].

This message indicates that the mail server is configured not to relay messages from other SMTP senders (i.e. StorEdge) to outside domains. The solution to this is to remove all email addresses not in the local DNS domain. The email messages may then be forwarded as needed.

2.19Hardware Warning Messages

Hardware replacement procedures can be located in Chapter 8, “FRU Replacement Procedures” in this book.

Log message: Controller write-back cache is disabled.

Log message: System on battery backup.

The power source has become unstable, and StorEdge now writes data to disk before confirming writes to clients, in case of complete power loss.

Specifically, this is an indication the RAID cache has been disabled. This message is caused by either an AC power failure or a discharged UPS. If there is an obvious indication of AC power loss that could last for some time, client systems should be disconnected and shut down.

If AC power has failed, the condition corrects itself after AC power is restored.

5310 NAS specifications

Sun Microsystems, known for its innovative computing solutions, launched the Sun 5310 Network Attached Storage (NAS) system, which marked a significant advancement in the realm of storage solutions in the early 2000s. The 5310 NAS was designed to provide high-performance, reliable, and scalable storage tailored for enterprise environments.

One of the standout features of the Sun 5310 NAS is its file-serving capabilities, which support multiple protocols, notably NFS (Network File System) and CIFS (Common Internet File System). This dual-protocol support allowed organizations to seamlessly integrate the NAS into diverse IT ecosystems, facilitating interoperability between UNIX, Linux, and Windows systems. The enhanced file-sharing capabilities made it an ideal solution for businesses with mixed operating environments.

The Sun 5310 NAS incorporates cutting-edge technologies to ensure high availability and data integrity. The system utilized a RAID (Redundant Array of Independent Disks) technology, providing various RAID levels to protect against data loss while optimizing performance. Additionally, the device featured hot-swappable drives, enabling maintenance and upgrades with minimal downtime, a crucial factor for business continuity.

Equipped with advanced management software, the Sun 5310 NAS offered users an intuitive interface for monitoring storage health and performance. This software included comprehensive reporting functionalities that allowed IT administrators to oversee usage patterns and capacity planning efficiently.

Scalability was another defining characteristic of the Sun 5310 NAS. The system could easily expand with additional storage modules, accommodating the growing needs of an organization without the necessity for complete system overhauls. This flexibility ensured that businesses could adapt their storage solutions to meet evolving data storage needs without incurring significant costs or disruptions.

In terms of performance, the Sun 5310 NAS featured high I/O throughput achieved through its robust hardware architecture and optimized file serving capabilities. This performance baseline was crucial for organizations that relied on heavy data workloads and required rapid access to information.

In summary, the Sun 5310 NAS from Sun Microsystems embodied a forward-thinking approach to network storage, blending reliability, scalability, and multi-protocol support. Its user-friendly management software, combined with the robustness of RAID technology and hot-swappable drives, made it a preferred choice for enterprises looking to streamline their storage infrastructure while safeguarding critical data.
