Enabling or disabling a host adapter

A host adapter can be enabled or disabled by using the storage command. You disable an adapter to replace hardware components or modules.

About this task

You might want to disable an adapter for the following reasons:
  • You are replacing any of the hardware components connected to the adapter.
  • You are replacing a malfunctioning I/O module.

You can disable an adapter only if all disks connected to it can be reached through another adapter. After an adapter connected to dual-connected disks has been disabled, the other adapter is not considered redundant; thus, the other adapter cannot be disabled.

Steps

  1. Identify the name of the adapter whose state you want to change by entering the following command:storage show adapter
    The field that is labeled “Slot” lists the adapter name.
  2. Enter the following command.
    If you want to... Then use this command
