Alert Definition Symptom Recommendations
Finally, check the following physical
hardware: the storage processors on
the array, the ber switch and the
Gigabit Interface Converter (GBIC)
units in the switch, the ber cables
between the ber switch and the array,
and the array itself. You must rescan
after making changes to make sure
that the targets are detected. If storage
connectivity is restored for all of the
aected host and storage device
combinations, the fault is cleared and
the alert canceled. If storage
connectivity for the devices indicated
is caused by a permanent loss or
change, you must cancel the fault alert
as a workaround. The alert will be
canceled automatically after that.
