To resolve the issue of a new Windows host being unable to connect to a volume on the E-Series system when all other hosts can, follow these steps:

Obtain the WWPN for the Windows HBA (B):The Worldwide Port Name (WWPN) is essential for zoning and establishing communication between the host and the storage system. Ensure you have the correct WWPN for the new Windows host’s HBA.

Create a single-initiator zone with the host and E-Series system (D):Zoning is crucial in SAN environments to control and secure the data paths. Create a single-initiator zone that includes the WWPN of the Windows host and the target ports of the E-Series system. This ensures that the host can see the storage.

Add a zone to the active zoneset (E):After creating the necessary zone, it needs to be added to the active zoneset on the Cisco MDS switch. The zoneset must then be activated for the changes to take effect, enabling the new host to communicate with the E-Series system.

These steps ensure that the new Windows host is properly zoned and can access the storage volumes without disrupting the existing configurations.

In a Dynamic Disk Pool (DDP), the system is designed to handle drive failures efficiently without impacting data availability. When a drive fails within a DDP and there is no free capacity, the data from the failed drive is rebuilt using preservation capacity within the DDP.

Dynamic Disk Pools use distributed sparing, which allows the spare capacity to be spread across all the drives in the pool rather than relying on dedicated hot spare drives. This distribution ensures that the rebuild process starts immediately and can be completed faster than traditional RAID systems because the workload is shared across more drives.

The preservation capacity is essentially reserved space within the DDP that can be utilized in the event of a drive failure to rebuild the data. This approach helps in maintaining redundancy and protecting data integrity even when a drive fails.

To create a Dynamic Disk Pool (DDP), the minimum number of drives required is 12. This minimum requirement ensures that there is enough capacity and redundancy to maintain the performance and data protection characteristics that DDPs provide.

Dynamic Disk Pools are designed to optimize data distribution and rebuild times. By using 12 drives as a baseline, the system can efficiently distribute data and parity information across the drives, improving fault tolerance and rebuild performance compared to traditional RAID configurations.

Verify that the E2812 host port SAS link up lights are illuminated

Explanation: The link up lights on the E2812 host port should be checked to confirm that the physical layer connection is established. If the lights are not illuminated, it indicates that there is no physical link between the host and the E2812 system, which would explain why the host cannot access the volumes.

Purpose: To collect detailed diagnostic information from a Brocade FC switch.

Command:supportshow

Usage: Gathers comprehensive diagnostic information for support and troubleshooting purposes. This includes switch status, configuration, and log details.

Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the data center power infrastructure can support it without overloading circuits.

Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center’s cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.

Ambient Temperatures: The operating environment’s temperature should be within the specified range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are controlled is crucial for optimal performance and longevity of the equipment.

Dual-purpose SFPs: These are transceivers capable of supporting multiple data rates, allowing for flexible deployment in different networking environments.

Supported Data Rates: In the scenario where you are reviewing the storage array profile to determine if dual-purpose SFPs are installed, a set of supported data rates of 32 Gbps,16 Gbps, 8 Gbps, and 4 Gbps indicates the presence of such SFPs. This enables the switch from iSCSI to FC without needing to replace the hardware.

Configuration: Once the correct SFPs are identified, the host protocol can be adjusted accordingly within the SANtricity System Manager to utilize the desired Fibre Channel speeds.

FIPS Compliance: The Federal Information Processing Standard (FIPS) requires all components within a system to adhere to specific security standards.

FDE Drives: Full Disk Encryption (FDE) drives are used to ensure data security.

Audit Failure: Adding an FDE drive as a spare to a volume group without proper encryption settings could cause a security audit to fail.

Solution: Ensure all spare drives in a volume group meet the FIPS encryption requirements.

Definition of Throughput: Throughput refers to the amount of data transferred from or to the storage system over a specific period. It is measured in units such as MB/s or GB/s.

Relevance to Performance Diagnosis: When diagnosing performance issues on an E-Series storage system, measuring throughput over an hour helps determine the data handling capacity of the system. This metric can reveal whether the system is processing data efficiently or if there are bottlenecks.

Methodology: Tools within the SANtricity System Manager can be used to monitor and log throughput, providing insights into the performance characteristics and potential areas needing optimization.
