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.
