•The database restoration section on page 124 of the Administrator’s Guide incorrectly states that you can restore a database without unassigning devices that are assigned to hosts that are shut down. In order to protect against unintended multiple-writer situations, you must unassign all of the devices from hosts and share groups in your SAN database. For some SANs, you may have to shut down hosts in order to unassign devices.

•Creating a new database now follows the same restrictions that apply to the database restoration procedure. You must unassign all of the devices in your SAN Manager LM database before trying to create a new database.

•SAN Manager LM’s Universal Partition Map (UPM) format does not support failover or multi-pathing.

•If the database resides on storage that supports failover, and a failover event occurs, the database will be inaccessible. If the administration application was open during a failover event and an administrative operation is attempted at any time after failover occurs, the operation may fail. To restore contact with the database, run the Scan for Devices command or close the SAN Manager LM application and then restart it.

•In the License Hosts dialog box, you cannot unlicense hosts that have assigned devices. To unlicense a host, first unassign all of its assigned devices.

•If a file-system volume (partition, logical disk or fault-tolerant volume) from a Windows NT host’s internal hard drive(s) is missing (there is no drive letter assigned to the volume), it may be because all of the available drive letters have been taken by assigned SAN devices. To solve this problem, you must free up the drive letter and use Disk Administrator to assign it to the internal volume. To make the drive letter available, do one of the following:

–Identify the SAN device to which the letter is assigned. Run the SAN Manager LM administration application and unassign that device from the host.

–If the SAN Manager LM service is installed on the volume that is missing, the service will not be started and you will not be able to unassign any SAN devices. To solve this problem, unassign the SAN device’s drive letter in Disk Administrator and assign the drive letter to the internal hard drive partition.

Note

If any services or drivers failed to start because they are installed on the volume that

 

went missing, you may have to reboot the host after assigning the desired drive

 

letter to the volume.

 

 

•If the factory Qlogic HBA driver was previously installed and then removed through the SCSI Adapters control panel so it is not enabled, the SAN Manager LM installer will report that it has detected an active Qlogic HBA driver, and prompts you to remove the driver manually or automatically through the SAN Manager LM installer. To avoid this error message, if you installed and then removed the factory QLogic HBA driver from a host, change the value of the following registry path to 4 before running the SAN Manager LM installer:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\qlxxxx\Start

Note

The registry path will change depending on the QLogic driver that was installed. For

 

example, if the QLogic 2100 driver was installed, the registry path would be

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ql2100\Start

Surestore SAN Manager LM Software, Surestore SAN Manager DM Software specifications

HP Surestore SAN Manager DM Software and Surestore SAN Manager LM Software are integral components in the realm of storage area networks (SAN), designed to provide comprehensive management for a variety of storage devices. These software solutions enable organizations to optimize their storage resources, streamline processes, and enhance data accessibility throughout their infrastructures.

One of the main features of HP Surestore SAN Manager DM (Device Management) Software is its capability to facilitate centralized management of diverse storage devices. This includes configuration, monitoring, and troubleshooting capabilities that help IT administrators maintain optimal performance and operational efficiency. The software offers intuitive dashboards and real-time alerts, allowing users to quickly identify and address issues as they arise.

Another key feature of the DM software is its advanced reporting capabilities. Users can generate detailed reports on storage usage, performance metrics, and device health status, providing valuable insights that inform strategic decisions regarding capacity planning and resource allocation. This level of visibility is crucial for organizations looking to ensure their storage infrastructure aligns with evolving business needs.

On the other hand, HP Surestore SAN Manager LM (Lun Management) Software focuses specifically on managing logical unit numbers (LUNs) within the SAN. One of its standout features is the ability to create, resize, and delete LUNs seamlessly, enabling administrators to adjust storage allocations in response to changing workloads. It also supports LUN masking and mapping, enhancing security and ensuring that only authorized hosts can access specific storage resources.

The LM software offers advanced features such as dynamic LUN management, which allows for real-time adjustments without disrupting operations. This ensures that organizations can remain agile and responsive in the face of fluctuating storage demands. Additionally, the LM software integrates smoothly with backup solutions, ensuring that data protection measures are aligned with the management of storage resources.

Both HP Surestore SAN Manager DM and LM Software utilize advanced technologies to deliver high availability and reliability. Features such as data integrity verification and automated failover processes contribute to a robust infrastructure that minimizes downtime and protects against data loss.

Together, these software solutions provide a comprehensive framework for managing storage area networks, offering organizations the tools they need to improve performance, enhance security, and ensure data accessibility. By leveraging HP Surestore SAN Manager DM and LM Software, businesses can better navigate the complexities of modern data management, ultimately fostering greater efficiency and innovation across their operations.
