Active mirrored load source fails late in the initial program load (IPL) or at run time
When an active mirrored load source fails after storage management recovery is completed, it is treated like a failure in any other mirrored pair.
- If the other storage unit in the mirrored pair is present and active, the failing unit is suspended and the system continues to run using data the data on the remaining active unit of the pair.
- If the failing storage unit is the last active unit of the mirrored pair (the other unit of the pair is either suspended or resuming), the system displays a Disk Attention system reference code and becomes unusable.
