0x3001a WARNING True Storage
Volume
Latency
Degraded
Storage
volume I/O
latency has
increased
above an
acceptable
threshold.
The average
I/O latency
on a storage
volume has
exceeded
the
acceptable
limit, likely
due to
increased
latency on
the backend
storage
array or
fabrics
between the
metro node
and storage
array.
1. Analyze
the latency
stats from
the storage
array for the
volume in
question at
the time of
the event to
determine if
it reported
the same
high
latency.
Engage the
storage
array vendor
as needed.
2. If the
storage
array does
not report
the same
latency at
the time of
the issue for
the volume,
then
investigate
the fabrics
between the
metro node
and storage
array. 3. If
the issue
persists and
the cause
cannot be
determined
engage Dell
Customer
Service.
