Mirror Promoted on host

Once a volume has been promoted, the mirror cannot continue. Once a volume has been promoted it can not be a mirror again; however it can function as a master.

Waiting on host, link is down

This is typically a connection problem between the two system. Check the cables and the network connectivity. The master system will continue to send changed data to the buffer. Once the buffer is filled the mirror will crack.

Error Initializing mirror buffer

This error occurs when the master system does not have enough free space to create a mirror buffer. Try creating a smaller buffer. Minimum buffer size is 100mb.

Mirror stops when creating buffer

On the master system Sync status "displays syncing to host 0%" and system log displays "updating mirror and volume information" but nothing is happening.

1.Go to the mirror system

2.Access the StorEdge via Telnet, serial console, or keyboard console.

3.When the menu prompt appears enter "admin" and then press the Enter key.

4.Enter the administrator password for the StorEdge and then press the Enter key.

5.From the command line enter menu and select option 2 system log. The system log displays the following error message:

Invalid password from host- The password provided on the master system is incorrect.

6.Go back to master system and break the mirror.

7.Add a new mirror and enter the correct administrator password for the mirror.

Whenever a mirror problem exsists it is best to view both systems and their respective logs.

Not enough space to create mirror buffer

To check the amount of space available for a mirror buffer, proceed as follows:

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.
