DSP Status A percentage of DSP resources are
unavailable. The failure of one or more,
but not all, DSPs results in a Minor
alarm. Critical alarm indicates that all
DSPs have failed. In the event of an
alarm, reset the system as soon as
possible. If the DSP continues to fail,
replace the module.
Use the Show Status DSP maintenance
command to identify status of DSPs in the
controller.
Install required DSP modules. See “Increasing
DSP Resources” in the “Installation Planner”
chapter of the MCD Technician’s Handbook for
instructions.
DSP licenses are enabled but not
enough DSP resources are available to
support compression requirements
Install required DSP modules. See “Increasing
DSP Resources” in the Installation Planner chapter
of the MCD Technician’s Handbook for
instructions.
Faulty circuit on DSP module Replace DSP module.
DSP Card Status DSP card is defective. For a defective DSP module, ensure that the
module is seated securely.
For an embedded DSP failure, replace the
controller. Use Show Status DSP to identify the
location of the defective module.

KB11-5191-00213.
If the alarm occurs on the secondary drive, check
the primary drive for faults. (In some cases, the
primary drive has a sector error while the
secondary drive is fault free.)
