Terminology

Some of the terms used in this guide are similar and some have changed slightly as technology changes. The following definitions apply:

HBA Port

HBA Port refers to the actual physical port on an HBA. For example, a

QLA2462 has two ports called HBA port 1 and HBA port 2.

HBA Instance, HBA Instance number, or HBA Port Instance

When you install HBA in a system with other HBAs, each HBA port gets assigned a number by the driver or API so it knows which HBA to communicate with. This assigned number might be called HBA Instance, HBA instance number, or HBA Port Instance.

HBA Alias

When an alias is assigned to a physical HBA, no matter how many ports that HBA has, the HBA Alias refers to the HBA, not one of its ports.

Port Alias

You can also assign an alias to an individual port on an HBA. This Port Alias refers to only that port and none other.

Thus, an HBA can only have one HBA Alias, but each port on that HBA must, have a unique Port Alias.
