Troubleshooting the Sun StorEdge MultiPack-FC
Then:
See FIGURE 2-1 for drive LED
locations.
1. Amber LED is lit.
2. Drive LED is not lit.
3. Green LED is lit.
Check the connection between
the drive connector and the
connector on the backplane.
1. Check the power cord
connection to the unit (power
inlet) and to the power outlet
(FIGURE 2-7).
2. Check the unit to determine
if it is receiving power, and that
the power switch is in the "on"
position (FIGURE 2-7).
Check the box ID switch on the
back of the unit. There may be a
box ID conflict (FIGURE 2-7).
Power cord is secure and power
switch is in the "on" position,
but the unit is not receiving
power.
Check the input/output cable
connections.
Action(s):
1. Drive is bad. Replace the drive.
2. Reseat the drive. Verify that green LED is lit.
3. There is a backplane problem. Replace the
backplane.
Make sure the drive is seated in the correct
drive bay.
Make sure the drive bay is pushed all the way
in and the bracket handle is latched correctly.
1. Secure the power cord connections if they are
loose (FIGURE 2-7). Verify that the power LED
is lit (FIGURE 2-1).
2. Verify that the power supply fans are
spinning. If the unit appears to be powered on
except for the presence of the LED light, replace
the LED clip and cable.
Power off the box. Change the box ID of the
other box so that each box has a unique box ID
[1-2] (FIGURE 2-7). Power on the box and enter
a software command sequence to list all drives
with a clean device table (FIGURE 2-8).
Replace the power supply.
1. Check all cable connections between the host
and the MultiPack-FC for tightness.
2. Try different cable(s) of known good
continuity.
3. Check that the host and/or host adapter are
functioning normally.
