Removing or replacing a PCI hot plug adapter

Edit online

You can remove or replace a PCI hot plug adapter from the system unit without shutting down the operating system or turning off the system power. Removing an adapter makes the resources provided by that adapter unavailable to the operating system and applications.

Before you can remove an adapter, you must unconfigure it.

The following are the procedures for removing a PCI hot plug adapter. You can complete these tasks with the SMIT or system commands. To perform these tasks, you must log in as root user.

Replacing an adapter with another adapter of the same type retains the replaced adapter's configuration information and compares the information to the card that replaces it. The existing device driver of the replaced adapter must be able to support the replacement adapter.

SMIT fastpath procedure

  1. Type smit devdrpci at the system prompt, then press Enter.
  2. Use the SMIT dialogs to complete the task.

To obtain additional information for completing the task, you can select the F1 Help key in the SMIT dialogs.

  • The lsslot command displays a list of all the PCI hot plug slots and their characteristics.
  • The lsdev command displays the current state of all the devices installed in your system.
  • The drslot command prepares a hot plug slot for removal of a hot plug adapter.
