TROUBLESHOOTING GUIDE
If your disk system is not performing normally, review these
points:
1.
Be sure the drive fuse is the proper value. Place all switches
under
the lights on the front panel
to
the left position. Then
connect the ac cord, provided with the drive,
to
your drive and
to
a wall socket.
2.
Power on the drive and wait for it
to
come ready (as long as 40
seconds). When all the lights on the front panel go
off
and the
ready
light stays on, the drive is ready and all should be well. Go
to
the following section titled "Checking the firmware version."
3.
If the Corvus disk system fails to come ready,
try
the
following
procedures:
• Insure all cables are properly connected and switches are in
the correct position for the operating configuration.
• Reset the drive manually using the reset switch on the
front
panel. If the drive now comes ready, the electro mechanical
head lock may have been stuck. Otherwise:
• Power down the disk system and initiate the power
up
se-
quence again.
4.
If your drive still does
not
come ready, power down.
Power down your drive and switch the format switch
to
the
right. This is the third switch
to
the right, under the
indicator
lights. Repeat the power up sequence. If your drive now comes
ready, you need
to
put
new firmware on your disk.
First go
to
the following section titled "Firmware update
or
replacement" and
try
to update your firmware. If the update
takes, then your drive
should
be
all right.
If the update is interrupted by a R/Werror message, you need
to
format the drive according
to
the sUbsection titled: "Replacing
the firmware."
5.
You
may also need to spare tracks or update the virtual
drive
table. If so,
see
the appropriate following sections.
6.
If none
of
the previous suggestions work, contact the nearest
Corvus Systems Service Center
for
assistance.
