Overview of the Procedure

The workflow for replacing an HBA is as follows. Perform the following procedure.

1. Check the connection status between the host and the storage system.

   Refer to "Checking the Connection Status Between the Host and the Storage System" for details.

2. Replace the HBA in the host and connect the host and the storage system.

   This operation must be performed by a maintenance engineer.

3. Perform the system settings according to the connection status that was checked in 2.

   • When the host affinity settings are used

     Settings for the storage system are required. Refer to "Required Storage System Settings After HBA Replacement (When Host Affinity Settings are Used)" for details.

   • When the host affinity settings are not used (conventional LUN mapping is used)

     Settings for the storage system are not required. This ends the replacement procedure for an HBA.

The following procedure is an example when a FC interface is used between the host and the storage system.

The same procedure can basically be used even when the interface type is iSCSI.
