% Problem
40 Description: The SSA adapter has
detected an open SSA link. This problem
is caused either by a disk drive module
40 that is failing, or by a disk drive module
20 that has been switched off from another
using system on the same SSA link.
(That using system has itself been
switched off.)
Action: If the SSA service aids are avail-
able, run the Link Verification Service Aid
to determine which device is preventing
configuration. (That device is the one
beyond the last-configured device on an
open SSA link.)
– Description: The SSA adapter has
detected a link configuration resource that
is not valid.
Action: See "SSA Loop Configurations
That Are Not Valid" on page 5-12.
100 Description: The SSA adapter failed to
respond to the device driver.
Action: Exchange the FRU for a new
FRU.
100 Description: A data parity error has
occurred.
Action: Exchange the FRU for a new
FRU.
100 Description: An SSA adapter direct
memory access (DMA) error has occurred.
Action: Exchange the FRU for a new
FRU.
100 Description: A channel check has
occurred.
Action: Exchange the FRU for a new
FRU.
100 Description: A software error has
occurred.
Action: Go to "Software and Microcode
Errors" on page 5-2 before exchanging
the FRU.
100 Description: A channel check has
occurred.
Action: Exchange the FRU for a new
FRU.
