centralMemoryTest

The centralMemoryTest command is used to check the central memory in each
ASIC as follows:
v The built-in self-repair (BISR) circuit in each ASIC chip does not report failure to
v The data cells can be uniquely written and read correctly (data write/read test).
v The data in any one ASIC can be read from any other ASIC (asic-asic test_).
v Bad parity can be detected and flagged in the error register and interrupt posted
v Buffer number error can be detected and flagged in the error register and
v Chip number error can be detected and flagged in the error register and interrupt
Attention:
Fibre Channel hub. Before issuing the centralMemoryTest command, disable the
Fibre Channel hub using the switchDisable command.

cmiTest

The cmiTest command verifies that control messages can be correctly sent from
any ASIC to any ASIC. It also tests that the checksum check is OK.
