See About online dynamic reconfiguration

Before you replace a host bus adapter (HBA) online, you must disable the I/O paths to the controller. After you replace the HBA, you enable the I/O paths.

To replace a host bus adapter online

  1. Disable the paths to the controller by removing the reference from DMP. Enter the following. In this example, the controller name is fscsi.

    # vxdmpadm -f disable ctlr=fscsi
  2. Remove the device references from the operating system. Enter the following:

    # rmdev -Rdl fscsi
  3. Rescan the device tree and rebuild the DMP database. Enter the following:

    # vxdctl enable
  4. Replace the host bus adapter.

  5. Reconfigure the devices in the operating system. Enter the following:

    # cfgmgr
  6. Verify that new devices appear at the operating system level.

    # lsdev -Cc disk
  7. Enable the controller. In this example, the controller name is fscsi.

    # vxdmpadm enable ctlr=fscsi
  8. Rescan the device tree and rebuild the DMP database.

    # vxdctl enable
