BEST PRACTICES 7 Best Practices Setting up the WD Sentinel DX4000 Setting up Client Computers Using the WD Sentinel DX4000 Efficiently Replacing Drives Shutting Down The following practices help you use the WD Sentinel DX4000 and protect your data efficiently and safely. Setting up the WD Sentinel DX4000 Change the default name of WD Sentinel to something unique. This avoids conflicts when another WD Sentinel server is added to your network in the future.
BEST PRACTICES Replacing Drives The online removal of a drive forces a rebuild when the drive is replaced. Until the rebuild is complete, the RAID system is degraded and unrecoverable failure will occur should another drive be removed. Only remove one drive at a time between rebuilds. Avoid pulling a drive out unless there is a failure. When a drive needs replacement, the WD Sentinel server is still functional but subject to a second drive failure that would result in the loss of data.
TROUBLESHOOTING 8 Troubleshooting First Steps Checklist Specific Problems and Corrective Actions For any issue, first ensure that you are using the latest firmware for the WD Sentinel server. See “Updating Software” on page 24 for instructions. First Steps Checklist Is the power supply plugged in to the wall outlet and the drive? Are all cables correctly connected and secured? Is the power on? If not, see “LEDs” on page 12.
TROUBLESHOOTING 3. Click Browse to find the folder that you want to map, or type the path to the server using the format \\ServerName\FolderName. For example, if the share is called Documents, and your server is called MyServer, you would enter \\MyServer\Documents. 4. If you want the drive to reconnect whenever the computer is rebooted, click the Reconnect at logon check box. 5. Click Finish.
