After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.

NetApp Documentation on Space Reclamation

The vserver fcp wwpn-alias set command is used to set or modify the World Wide Port Name (WWPN) aliases for Fibre Channel (FC) ports in a NetApp ONTAP environment. This command allows you to apply a company-wide naming policy to FC ports, ensuring consistent and easily identifiable naming conventions across your storage infrastructure.

To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:

ping -M do -s 8972

In this command:

-M do ensures the packets are not fragmented.

-s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header).

By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.

NetApp ONTAP 9.14.1 supports up to a 16-node cluster for SAN and NAS configurations. Given a current 10-node cluster, you can add up to 6 additional nodes to reach the maximum supported node count. This expansion capability ensures scalability for growing storage needs while maintaining high availability and performance.

To verify compatibility in an iSCSI storage environment before a NetApp ONTAP software upgrade, the following tools are recommended:

Interoperability Matrix Tool (IMT): This tool helps verify the compatibility of different components, including network switches, hosts, and storage systems, ensuring that the planned upgrade will be supported.

Active IQ OneCollect: This tool collects comprehensive configuration and performance data from the storage environment, which can be used to assess the current setup and identify any compatibility issues before the upgrade.
