IBM 3590 - Manual (Page 43)

FID 2:
v Creation: A FID 2 message is created when the device microcode detects a
permanent failure of a serious nature that puts the device in a degraded
state. The drive can still be used, but it is in a less available state. If a
subsequent FID 2 message is generated, it replaces any earlier FID 2
messages.
v Stored: A FID 2 message is stored and overlaid when a higher priority
message is displayed.
v Displayed: A FID 2 message is displayed when it is not overlaid by a
higher priority message.
v Deletion: FID 2 messages are deleted by a power cycle or the generation of
a new FID 2 message.
FID 3:
v Creation: A FID 3 message is created when the device microcode detects a
permanent failure of a moderate nature that puts the device in a degraded
state. The drive can still be used, but is in a less available state. If a
subsequent FID 3 message is generated, it will replace the earlier FID 3
messages.
v Stored: A FID 3 message is stored and overlaid when a higher priority
message is displayed.
v Displayed: A FID 3 message is displayed when it is not overlaid by a
higher priority message.
v Deletion: FID 3 messages are deleted by a power cycle or the generation of
a new FID 3 message.
FID 4:
v Creation: A FID 4 is created when the device microcode detects a
permanent failure in service circuitry (circuitry that is used only to check
functional circuitry). An example of a FID 4 is when JTAG circuitry breaks.
v Stored: Any higher priority message (FID 1, Attention, Routine Message,
FID 2, or FID 3) will cause a FID 4 message to be stored and overlaid.
When a FID 4 message is displayed and the Enter button is pressed, the
FID 4 message will be deleted.
v Displayed: A FID 4 message is displayed when it is not overlaid by a
higher priority message.
v Deletion: FID 4 messages are deleted by a power cycle or the generation of
a new FID 4 message.
FID and ATTN Supplemental Messages
Table 5 on page 24 lists messages that are sent to the operator panel and the
appropriate operator action. See Figure 6 on page 16 for the location of the
supplemental messages.
