6.10 Memory Self-Test Errors

If an <REFERENCE>(xma2) node fails self-test, an explicit

memory test is run on the failing module and console error

messages are displayed. The failing module is still included

in the memory conﬁguration.

Example 6–3: MS65A Memory Module Node Exclusion

>>> SET MEMORY /INTERLEAVE:(8+9, A)

>>> INITIALIZE

>>> SHOW MEMORY

/INTERLEAVE:(8+9, A)

If an <REFERENCE>(xma2) node fails self-test, then the console executes

an explicit memory test during the building of the bitmap. Failing memory

modules are included in the conﬁguration, although they are interleaved by

themselves. The only way to exclude a memory module from interleaving

is to use the SET MEMORY command without designating the node you

want to exclude. Example 6–3 shows how to exclude the memory module

at node 7.

During the explicit memory test, any number of the following console

messages might be displayed to aid the customer service engineer in

diagnosing the problem.

?37 Explicit interleave list is bad. Configuring

all arrays uninterleaved.

This means that the explicit set of memory arrays for the explicit interleave

includes no nodes that contain memory arrays. All memory arrays found

in the system are unconﬁgured (the SET MEMORY command may have

speciﬁed nodes that did not contain memory modules).

?45 Memory interleave set is inconsistent: n n ...(<REFERENCE>(xyp) msg.)

?46 Memory interleave set is inconsistent: n n ...(<REFERENCE>(XRP) msg.)

This means that the listed nodes (n n) do not form a valid memory interleave

set. One or more of the nodes might not be a memory array or the set

contains an invalid number of memory arrays. Each listed memory array
