Depending on your storage system, you can configure Fibre Channel (FC), Internet Small Computer System Interface (iSCSI), or a Network File System (NFS) configuration that uses NFS directory trees.
FC or iSCSI configuration checks
Although Fibre Channel Protocol (FCP) and Internet Small Computer System Interface (iSCSI) were once distributed as separate utilities, you can find both FCP and iSCSI configuration support available in AIX Host Utilities.
NFS configuration checks
For configurations that use Network File System (NFS), you must check that NFS clients are operating correctly, before you set up your host and storage systems.
