4–22 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
■●❍❍●❍●
25 Recursive Bugcheck detected.
The same bugcheck has occurred three
times within ten minutes, and controller
operation has terminated.
Reset the controller. If this fault pattern is
displayed repeatedly, follow the repair
action(s) associated with the Last Failure
code that is repeatedly terminating
controller execution.
■●❍❍●●❍
26 Indicated memory module is missing
Controller is unable to detect a particular
memory module.
Insert memory module (cache board).
■●❍❍●●●
27 Memory module has insufficient usable
memory.
Replace indicated DIMM(s).
(This indication is only provided when
Fault LED logging is enabled).
■●❍●❍❍❍
28 An unexpected Machine Fault/NMI
occurred during Last Failure processing.
A machine fault was detected while a
Non-Maskable Interrupt was processing.
Reset the controller.
■●❍●❍❍●
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’s software).
■●❍●❍●❍
2A All cabinet IO modules are not of the
same type.
Cabinet I/O modules are a combination of
single-sided and differential.
Make sure that the I/O modules in an
extended subsystem are either all
single-ended or all differential, not both.
■●❍●❍●●
2B Jumpers not terminators found on
backplane.
One or more SCSI bus terminators are
either missing from the backplane or
broken.
Make sure that cabinet’s SCSI bus
terminators are installed and that there
are no jumpers. Replace the failed
terminator if the problem continues.
■●❍●●❍❍
2C Cabinet IO termination power out of
range.
Faulty or missing IO module causes
cabinet IO termination power to be out of
range.
Make sure that all of the cabinet’s device
SCSI buses have an I/O module. If
problem persists, replace the failed I/O
module.
