Use this procedure when you are preparing to unconfigure
a hot-plug Small Computer System Interface (SCSI) device or cable.
This procedure will help determine if a SCSI device or SCSI device
cable is causing your system problem.
Disconnect all cables attached to the adapter, (except
for the cable to the device from which you boot to run diagnostics;
temporarily move these device cables to another SCSI port while you
are trying to find the problem).
- Go to Running the online and stand-alone
diagnostics and perform the prerequisite tasks
described in the Before you begin topic.
- Determine which SCSI adapter you plan to remove the cables
or devices from.
- Adapter slots are numbered on the rear of the system unit,
record the slot number and location of each adapter being removed.
- Ensure that any processes or applications that might use
the adapter are stopped.
- Enter the system diagnostics by logging in as root user
or as the CE login user. Type the diag command
on the AIX® command
line.
- When the DIAGNOSTIC OPERATING INSTRUCTIONS menu displays,
and press Enter. The FUNCTION SELECTION menu appears.
- From the FUNCTION SELECTION menu, select Task Selection,
and then press Enter.
- From the Task Selection list, select Hot Plug Manager,
and select PCI Hot Plug Manager.
- From the PCI Hot Plug Manager menu, select Unconfigure
a Device, and then press Enter.
- Press F4 or ESC+4 to display the Device Names menu.
- Select the adapter from which you are removing the cables
or devices in the Device Names menu.
- In the Keep Definition field, use the tab key to answer
Yes.
- In the Unconfigure Child Devices field, use the Tab key
to answer Yes, then press Enter. The ARE YOU SURE screen is displayed.
- Press Enter to verify the information. A successful deconfiguration
is indicated by the OK message displayed next to the Command field
at the top of the screen.
- Press F4 or ESC+4 twice to return to the Hot Plug Manager
menu.
- Select replace/remove PCI Hot Plug adapter.
- Select the slot that has the adapter you want to remove
the cables or devices from in the system.
- Select Remove.
Note: A
fast flashing amber LED located at the back of the machine indicates
the slot that you selected.
- Press Enter. This places the adapter in the
action state, meaning it is ready to be removed from the system. (You
do not need to remove the adapter, unless it makes removing the cables
attached to it easier).
