To find the Worldwide Port Names (WWPNs) for a Windows host, you can check the following locations:

FC Switch (A):The WWPNs are available in the management interface of the Fibre Channel switch to which the host is connected. By accessing the switch's management tools, you can list all connected devices and their WWPNs.

HBA Vendor’s Utility (D):Host Bus Adapter (HBA) vendors typically provide utilities or management software that allows you to view the properties of the HBAs installed in the system. These utilities will display the WWPNs of the HBA ports.

Fabric attachFC topology is the most scalable host-side connection topology for E-Series systems.

This topology involves connecting the E-Series storage system to a Fibre Channel switch, which then connects to the hosts.

Scalability: The fabric attach topology supports a large number of devices by allowing multiple switches to be interconnected, forming a fabric.

Redundancy: It offers higher redundancy and failover capabilities because multiple paths can be created between the hosts and the storage.

References: NetApp Documentation (NetApp E-Series SANtricity Software, Implementation and Planning Guide).

Verify Switch Port Status:

Step:Check the status of the FC ports on the Brocade switch.

Reason:The ports need to be enabled for communication.

To increase the throughput of an iSCSI host port on a NetApp E-Series system, you should change themaximum transmission unit (MTU)setting from its default value.

Maximum Transmission Unit (MTU):The MTU size determines the largest packet that can be sent over the network without needing to be fragmented. By increasing the MTU size, you can reduce the overhead associated with packet processing and improve throughput. For example, setting the MTU to 9000 bytes (Jumbo Frames) can enhance performance for iSCSI traffic.

The pool is expanded by 800 GB

Explanation: When a larger drive (1.6 TB) is added to a Dynamic Disk Pool (DDP) that consists of smaller drives (800 GB), the pool expands only by the size of the existing drives in the pool. Hence, in this scenario, the pool would be expanded by 800 GB.

Cabling method: It is important to distribute the connections for redundancy and balanced performance.

EXP1 and EXP2 ports: By dividing these ports between the A-side and B-side IOM-12 modules, the system ensures balanced load and failover capabilities.

References: NetApp E-Series hardware setup and configuration guide.

Enable AutoSupport:

Step:Configure AutoSupport on the EF570 system with the option to store data locally.

Reason:This allows the system to generate and save support data without needing immediate Internet access.

Set Interval for Data Collection:

Step:Set AutoSupport to run at regular intervals.

Reason:Regular intervals ensure that up-to-date support data is available for NetApp.

Manual Data Transfer:

Step:Periodically transfer the collected support data from the local storage to a server with Internet access.

Reason:This server can then send the support data to NetApp.

Send Data to NetApp:

Step:Use the server with Internet access to forward the collected support data to NetApp's support systems.

Reason:This ensures NetApp receives the necessary support data for ongoing maintenance and troubleshooting.

TheHeadroom graphin SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.

This helps in understanding how much additional load the system can handle before reaching its performance limits.

RAID Levels Overview:

RAID 5: Single parity, moderate overhead.

RAID 6: Dual parity, higher overhead than RAID 5.

RAID 10: Mirroring and striping, highest overhead due to 100% redundancy (mirroring).

Dynamic Disk Pools (DDP): Efficient use of capacity but more overhead than RAID 5.

Overhead Calculation:

RAID 10 has the most overhead because it mirrors all data, effectively using twice the storage capacity.

Capacity Overhead: The overhead in RAID 10 is 50% of the total capacity, meaning if you have 1 TB of usable storage, you need 2 TB of total storage.

References: NetApp E-Series Storage Management Guide, RAID level comparison charts.

To enable multifactor authentication (MFA) on an E-Series system, follow these steps:

Map roles (C):Role mapping is necessary to define the permissions and access levels for different users when MFA is enabled. This ensures that only authorized users can access specific functions and data on the system.

Configure LDAP (D):LDAP configuration is required for integrating with directory services to manage user authentication and access control. LDAP settings need to be correctly configured to support MFA, allowing the system to authenticate users against an external directory service.

When integrating DE6600 shelves into a new E5760 environment that already has a stack of DE460C shelves, it is recommended to cable the DE6600 shelves at the end of the stack.

This approach maintains the integrity and performance of the existing stack while allowing for the addition of new shelves without disrupting current operations.

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.

Purpose: To display the average service time on a FC target port basis.

Command:fcp stats -i 5

Usage: Monitors Fibre Channel Protocol (FCP) performance, including service times for FC target ports at specified intervals (every 5 seconds in this case).

Understand ALB Requirements:Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.

Check Host Multipath Driver:

Verify if the host multipath driver installed supports ALB.

Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.

Review Host Type Compatibility:

Ensure the host types used in the configuration support ALB.

Certain host types might not be compatible, resulting in ALB malfunction.

Potential Causes:

Host Multipath Driver (C):If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.

Host Type (D):Incompatible host types can lead to issues with ALB implementation, causing imbalances.

Steps for Resolution:

Update or replace the host multipath driver with a version that supports ALB.

Reconfigure or update the host types to ensure compatibility with ALB.

Identify the Orphaned Volume:

Step:Use SANtricity System Manager to identify the orphaned volume.

Reason:To determine which volume has lost its mirror relationship.

Remove the Mirroring Relationship:

Step:Access the mirroring settings for the orphaned volume and remove the existing relationship.

Reason:The current relationship is invalid and needs to be removed to reset the configuration.

Re-create the Mirroring Relationship:

Step:Establish a new mirroring relationship for the previously orphaned volume.

Reason:To restore the asynchronous mirroring setup with a valid configuration.

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.

Explanation:

When AutoSupport is not automatically sending reports to NetApp's ActiveIQ tool, you can manually collect the support data using SANtricity System Manager.

The manual collection involves generating a support bundle that includes all necessary logs and system information.

This data can then be reviewed locally or sent to NetApp support for analysis if needed.
