Problem Solution
Drive will not power on ■ Check that the power indicator light
on the control panel is on. If it is not,
make sure the power switch on the
back panel is on.
■ Replace the power cord.
Host computer system does not
recognize the drive
■ Ensure the drive is connected and
powered on. The drive must be on
when booting the host computer for
the drive to be recognized.
■ If the drive is the last device on the
SCSI bus, check that it has been
terminated and that the maximum
cable length has not been
exceeded.
■ Check SCSI ID assignments and
resolve any conflicts.
■ Ensure you are connected to the
correct SCSI bus type. UDO drives
are LVDS devices.
■ If using a narrow (8-bit) HBA, make
sure that all addresses are in the
range 0 through 7.
■ For Windows operating systems, use
the device manager to rediscover
the drive.
■ For HP-UX, use ioscan to verify
that the HBA and attached devices
are claimed.
■ For other operating systems, refer to
the system administrators guide for
diagnosing missing peripherals.
