Check the load source device unit to ensure it is ready. Verify that the load source
media (tape or compact disk) is loaded properly and is a valid IPL media.
1. Power off the system from the control panel.
2. Power off the system from the control panel.
3. The failing item is one of the cards or devices that is attached to the interface

Check the cables and connections between the System Unit and the Base I/O
Tower. Check the cables attached to the load-source device. Reseat cables where
possible.
Change the IPL mode to manual, and the IPL speed to SLOW OVERRIDE(S)
using control panel function 2. Power on the system.
Does the same SRC occur ?
Yes No
↓
Follow the service actions for the new SRC.
Attempt to IPL from a different load source device:
v If the failing IPL was mode D from an optical storage device unit alternate
IPL media, then use the tape device unit as the load-source device and
attempt to IPL mode D. (Temporarily disconnect the optical storage device
unit from the system if possible.)
v If the failing IPL was mode D from an tape device unit alternate IPL media,
then use the optical storage device unit as the load-source device and
attempt to IPL mode D. (Temporarily disconnect the tape device unit from
the system if possible.)
Does the same SRC occur ?
Yes No
↓
Follow the service actions for the new SRC.
If this IPL was successful, then the failing item is the original alternate
IPL load-source device.
If the load-source is an optical storage unit, exchange the IPL media on
the compact disk in the alternate IPL optical storage unit. If replacing
the media does not work, try replacing the optical storage device unit.
If the load-source is a tape unit, exchange the IPL media on the tape in
the alternate IPL tape unit. If replacing the media does not work, try
replacing the tape device unit.
for the alternate IPL load-source device.
If the system has recently had new PTFs loaded and applied, or the failure first
occurred during an alternate mode D IPL, or a previous IPL ended in an
unexpected power off, then attempt to reload service processor code.
Contact your next level of support for instructions on reloading the service
processor code.
Is this system a Model 830 with SB2 System Unit and FC 9074 ?
Yes No

on page 709.
Remove the IOPs and IOAs, EXCEPT for the load-source IOP and the first
storage IOA.
Attempt to perform the alternate IPL.
