3 Overall
DS4800
Configuration
Needs
Attention
Amber LED Off On = A component in the storage
subsystem configuration has
developed a fault
Inspect the Needs Attention LEDs
on the other components in the
DS4800 Storage Subsystem and in
all connected DS4000 storage
expansion enclosures to isolate the
fault.
However, it is recommended that
you use the DS4000 Storage
Manager Subsystem Management
window to identify the cause of the
problem and use the Recovery
Guru to help fix the problems.
Some of the problems may not
cause the Needs Attention LED on
the individual CRU to light, but
they will cause this Overall
DS4800 Configuration Needs
Attention LED to light. For
example, a hard disk drive that
exceeds its PFA errors will cause
this LED to light, but the drive
Needs Attention LED for the
individual drive in the attached
storage expansion enclosure will
not light.
See “Troubleshooting the storage
subsystem” on page 109.
