This unnecessarily limits network bandwidth. The easiest solution is to link the cards at a lower level via port aggregation.

2.14File System Issues

Note – A full backup should be done before performing the following procedures.

File system inaccessible (mount failure)

Under certain circumstances, volumes may fail to mount. This will typically manifest as an “access denied” message returned to users attempting to access the data on the affected volume.

The first place to look for information on this is the StorEdge system log. The boot log is the beginning of the system log for each boot.

Review the bootlog for messages about the volume mount. The beginning of the mount process can be identified by the “sfs2” process identifying disk segments, as in this example:

sfs2: /vol1 - id=3F142D97, extent 1 of 1, version 0

A successful mount is indicated by the “<volumename> is complete” message, as in this example:

/vol1 is complete

If the current boot log indicates a successful mount, then the problem lies elsewhere, most likely in the area of Windows Domain security.

The most recent boot log is named “bootlog”. The next most recent is named “bootlog.1”, the naming convention continues on to the oldest file “bootlog.9”. Beginning with /cvol/bootlog, search through the files for the most recent successful mount of the volume. Then, check the following bootlog to locate the first occurrence of the mount problem.

The most common reason for the mount failure is a power loss or crash during the mount process. This causes a “mount failure” flag to be set on the volume. When StorEdge encounters this flag upon boot, it does not mount the volume, and logs the following message:

/vol1 not mounted, previous mount did not complete.

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.
