Are there any messages in the log other than “LUN Critical”? (Drive failed etc.)

Controller alarm may be beeping.

Follow instructions on drive replacement. Once the drive has been replaced, system will rebuild the drive and the LUN will go from critical to online.

Alarm will continue to beep until rebuild is complete. The alarm can be silenced from the RAID page of the GUI or from the menu.

2.16File and Volume Operations

StorEdge doesn’t allow creation of volumes larger than 256 GB.

The StorEdge volume creation screens allow you to create volumes up to 256GB. In order to create larger volumes, segments (also limited to 256GB) must be created and joined to the volume.

Free space not immediately available after delete.

By default, the StorEdge will delete files as a background process and frees blocks as this completes. This is done to provide better performance to foreground processes. If many files have been deleted and the system is very busy, it may take some time. This functionality is provided by the .attic$ directory feature.

The .attic$ directory can be found at the root of each volume. In rare cases, on very busy filesystems, the .attic$ directory can be filled faster than it can process deletes. This leads to a lack of free space and slow performance. In these cases, disabling the

.attic$ directory is recommended.

This is configurable only at the Command Line Interface (CLI).

1.To access the StorEdge CLI, connect to the StorEdge via Telnet, and type “admin” at the [menu] prompt and enter the administrator password.

2.At the CLI, enter “fsctl attic disable <volumename>”.

This must be done for each volume that requires the change. It is not necessary to delete the directory, but it is permissible to delete the files within the directory to reclaim the disk space.

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.
