And then the following message.

07/08/04 11:00:38 I sysmon[51]: Ctlr0: write-back cache disabled

If the power is returned to the UPS, you will see the following message:

07/08/04 11:01:09 I sysmon[51]: UPS: AC power restored

Front LCD panel message: “P21 Power 1 Failed”.

This is an indication that one of the two power supplies has failed. Verify that one or more of the following indicators are present:

The system status light on the front of the StorEdge is flashing green. The system status light on the back of the StorEdge is flashing green. The log should have a message “power supply unit 1 has failed” Front panel may have message in display “P21 power 1 has failed”

The StorEdge has 2 power supplies located in the back of the unit. The failed power supply may have a solid red LED.

If both power supply lights are green, see hardware reference guide for unit replacement locations.

Replace the failed power supply.

The light on one of the power supplies is amber.

This is an indication of a failed power cord. Verify the following: Verify that one or more of the following indicators are present: The system status light on the front of the StorEdge is solid amber. The system status light on the back of the StorEdge is solid amber. Verify that the cord is plugged into an AC source.

Reseat the power cord in the power supply.

Replace the power cord if reseating does not fix the problem. Replace the power supply if power cord replacement does not work.

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.
