nlmlmml 29 EMU protocol version
incompatible.
The microcode in the EMU and
the software in the controller are
not compatible.
Upgrade either the EMU
microcode or the software (refer
to the release notes that
accompanied the controller
software).
nlmlmlm 2A All enclosure I/O
modules are not of the
same type.
Enclosure I/O modules are a
combination of single-ended and
differential.
Ensure that the I/O modules in
an extended subsystem are
either all single-ended or all
differential, but not both.
nlmlmll 2B Jumpers, not
terminators, found on
backplane.
One or more SCSI bus
terminators are either missing
from the backplane or broken.
Ensure that enclosure SCSI bus
terminators are installed and that
no jumpers are installed. Replace
the failed terminator if the
problem continues.
nlmllmm 2C Enclosure I/O
termination power out
of range.
Faulty or missing I/O module
causes enclosure I/O termination
power to be out of range.
Ensure that all of the enclosure
device SCSI buses have an I/O
module. If problem persists,
replace the failed I/O module.
nlmllml 2D Master enclosure SCSI
buses are not all set
to ID 0.
Set the PVA ID to 0 for the
enclosure with the controllers. If
the problem persists, try the
following repair actions:
1. Replace the PVA module.
2. Replace the EMU.
3. Remove all devices.
4. Replace the enclosure.
