  Restoring Initial System Setup

This section provides instructions on how to recover the NAS system if the operating system or a hard drive fails. Additionally, this section provides information for possible solutions that do not require restoring the operating system or hard drives.

Because your NAS system is designed to have redundancy, it can recover from certain hardware and software failures. In some situations, it can recover automatically, and in others, you must have administrator privileges and manually intervene to recover the NAS system.

Use the following methods in the order listed to restore your NAS system:

1. Check all of the items in "Solutions to Try Before Reinstalling."
   
   
2. Swap the operating system hard drives as described in "Booting From the Recovery Operating System Mirror Hard Drives."
   
   
3. Reinstall the operating system as described in "Recovering From an Operating System Failure."
   
   

Solutions to Try Before Reinstalling

This section provides checks and solutions that you should try before you reinstall your operating system or replace a hard drive. Some of the checks require you to observe the LEDs on the front and back of the NAS system. For more information about the LEDs, see your Installation and Troubleshooting Guide.

• Does the power LED show that the NAS system is turned on? If not, is the power cable connected to the NAS system and a power source?
  
  
• Are the link LEDs on the NAS system and any network switches to which it may be connected illuminated?
  
  
• Are you are using a standard Ethernet cable to connect to the network? Do not use the cable labeled "Ethernet Crossover Cable" that was shipped with your system.
  
  
• Have you allowed enough time for the NAS system to boot? The NAS system typically takes at least 5 minutes to boot.
  
  
• Does the NAS system boot completely? Use console redirection to connect to the NAS system and observe the boot process. See "Console Redirection" in "Troubleshooting."
  
  
• Can you connect using a serial connection? See the serial connection procedures in "Configuring the NAS System for the First Time" in "Initial Setup." If you can connect, then there may be a problem with your network.
  
  
• Are the LEDs for all four hard drives on the NAS system lit? If they are not all lit, you have a failed hard drive. See "Hard-Drive Failures."
  
  

Hard-Drive Failures

Your NAS system has a mirror of the operating system on hard drives, which allows you to recover in most cases. Depending on which drive fails, use one of the procedures in Table 5-1 to recover from a hard-drive failure.

Table 5-1. Hard-Drive Recovery Procedures

Hard Drive That Failed	System Automatically Boots From Hard Drive	Necessary Action
Hard drive 0	1	Replace the failed hard drive. See "Replacing Hard Drive 0."
Hard drive 1	0	Replace the failed hard drive. See "Replacing Hard Drive 1, 2, or 3."
Hard drive 2 or 3	0 and 1	Replace the failed hard drive. See "Replacing Hard Drive 1, 2, or 3."
More than two hard drives fail	NA	Reinstall new hard drives and the operating system. To replace the failed hard drives and reinstall the operating system, follow the procedures in "Replacing Hard Drives" and "Recovering From an Operating System Failure."

Software Failures

To recover from the following software failures, use one of the following procedures:

• If the main operating system files are missing or corrupt, you must manually boot from the recovery operating system mirror hard drives 2 and 3. For instructions, see "Booting From the Recovery Operating System Mirror Hard Drives." After the system is running, you can boot the system back to the main operating system hard drives and then perform a system-state restore operation. See "Restoring System-State Data After Reinstallation."
  
  
• If the main operating system mirrored partition fails, you must manually boot from the recovery operating system mirror hard drives 2 and 3 and restore the original files to the main operating system hard drives 0 and 1. See "Replacing Hard Drive 0." After the system is running, you can boot the system back to the main operating system hard drives and then perform a system-state restore operation. See "Restoring System-State Data After Reinstallation."

Recovering From an Operating System Failure

If the operating system for your NAS system fails, use one of the following methods to recover:

• Recover data by booting from the recovery mirror hard drives (recommended)
  
  
• Reinstall the operating system using a dedicated Microsoft® Windows® 2000 client system
  
  
• Reinstall the operating system using a Windows 2000 system that is on the same LAN
  
  
• With a DHCP server
  
  
• Without a DHCP server
  
  
• Use an existing Preboot Execution Environment (PXE) server
  
  

NOTICE: This procedure resets your NAS system to the Dell™ default settings and deletes all data on the NAS system. Before performing this procedure, attempt to boot from the operating system image on the mirrored hard drives. See "Booting From the Recovery Operating System Mirror Hard Drives."

Booting From the Recovery Operating System Mirror Hard Drives

You might need the NAS system to boot from the recovery operating system mirror so that you can perform a file restore on the main operating system mirror or access the data on the data partition and back it up to tape.

NOTE: The recovery operating system mirror is intended as a temporary way to back up your data. After performing the backup, you should reinstall the operating system using the procedures in "Reinstalling the Operating System."

To boot from the recovery drive, perform the following steps:

1. Shut down the NAS system.
