PS12000 Hard Disk Drive
Identifying a Faulty Hard Disk Drive
Symptoms of a faulty hard disk drive can emerge in several ways, including read/write errors
appearing in the Sky UI banner and failure to boot the operating system. If you are
experiencing errors that you suspect might be related to the hard drive, run the tests below.
Follow these steps to find out which hard disk drive is faulty:
1. Check the Data hard disk drive:
a. Access the appliance CLI session.
b. Change directory using the following command:
cd 9.258/
c. If you receive errors after issuing the command, the data drive might require
replacement.
2. Check the System hard disk drive (necessary only if the appliance does not boot up):
a. Power down the appliance.
b. Connect a null-modem serial cable to the appliance from a workstation and open a
terminal emulation program. See the
PacketShaper Quick Start Guide for more
information on terminal emulation software settings.
c. Power on the appliance.
d. If No sys appears in the console output during bootup, the system drive might
require replacement.
Note : If you encounter errors while running the tests listed above, please contact Blue
Coat Support.
