Hard Disk Drive Replacement
DOCUMENT OVERVIEW
Who Should Use This Instruction Set
This MaxAttach NAS 4000 Series by Maxtor HDD Replacement Instruction Set is intended as an important aid in identifying, and successfully replacing a specific failed drive.
Document Applicability
Use this replacement procedure only for the following systems: n MaxAttach NAS 4000 Series
n Microsoft Windows-Powered O/S version 2.2
WARNING
Back up all your user data before using this procedure. Failure to follow the steps in this procedure may result in loss of all user data, locking up the system, or both. Be sure of your failed disk diagnosis before attempting any replacement procedures.
Important Warnings
The procedure involves replacing a disk drive that is a member of a redundant array of
independent disks (RAID), specifically a RAID 5 array which uses spanning and parity writing to provide enhanced data protection features in the case of a SINGLE disk drive failure.
WARNING
Failure to exactly follow this procedure can lead to the loss of all user data, system re-boot failure, or both.
General Recommendations
n Follow the procedure steps exactly.
n Once the cover is removed from your system, clearly mark all drives with their physical drive number. When viewed from the front of the chassis, the drives have the following physical, logical and RAID 5 definitions:
• First drive on the left - Primary Slave Drive 1 - PS-D1
• Second drive on the left - Secondary Master Drive 2 - SM-D2 • Third drive on the left - Primary Master Drive 0 - PM-D0 • Fourth drive on the left - Secondary Slave Drive 3 - SS-D3
n Use the Identify Disk utility to determine which drive has failed or is missing from the array. n Perform all prerequisite steps before physically removing the drive from the chassis.
n Replacement drives must be the at least the same size as the failed drive.
• However, during the RAID rebuild process, a larger drive will be automatically re
configured to match the smallest drive in the array so that all drives end up being the same size.
n Make sure the jumpers on the replacement drive match those on the failed drive.
n Keep the failed drive in a safe place until you have completely restored the system to correct operation and all data is verified as complete.
n Perform all post installation reconfiguration steps as required. n If in doubt, call for technical support.
IdentifyDisk.Exe Utility Requirements
The IdentifyDisk.Exe utility is used to identify missing physical disks from the system arrays. Running from a DOS shell, it will identify all found and all missing disks.
n Utility Name:
• Identify Disk Utility n File Name:
• IdentifyDisk.Exe n Available On:
• Your system located at C:\Drivers
• http://www.maxtor.com/products/MaxAttach/Downloads/downloads.htm • Download to your client administration system and/or to a floppy disk. Disk Replacement Requirements

n Microsoft Window-Powered O/S Revision 2.2
Array of Independent Disks), and DOES NOT cover other user determined configurations such as JBOD (Just A Bunch of Disks), RAID 0 - Striping, or RAID 1 Mirroring.
WARNING
If you have re configured your array to another RAID method such as RAID 0, RAID 1, RAID 0+1, or JBOD, stop and do not continue this procedure. Instead, call technical support for additional information as to the best way to proceed. The MaxAttach NAS 4000 Series contains four internal disk drives. To determine the drive size of your MaxAttach NAS 4000 Series, check the model number on the label of one of the installed drives. Make sure the replacement drive has at least the same or higher drive capacity as the failed drive. Make sure the new drive has the jumper settings as the failed drive.
Document Conventions
n All descriptions of drive locations are when viewed from the front of the unit. n All mouse clicks are “left-clicks” unless otherwise specified as “right-clicks.”
n Objects of user actions taken by the user are in bold face such as “click on the OK button.” n The names of screens, windows, figures, and dialog boxes are in italics such as “the Disk and
Volumes Status screen appears.”
n Commands typed in the user, usually in a DOS shell interface, are entered as Courier text as in “to find the IdentifyDisk.Exe utility, type dir at the C:\> prompt.

Internal Disk Array Architecture
The factory default disk drive configuration has the following parameters: n There are three logical volumes: C:\, D:\, and E:\.
n Logical volumes C:\ and D:\ are reserved for the operating system (O/S). • Each O/S volume is spread across two physical drives.
• Each O/S volume resides in a partition separate from the user data.
• Each O/S volume is configured as a RAID 1 (Redundant Array of Independent Disks type 1 array) mirrored array.
n Logical volume E:\ is available for user data.
• The user data volume is spread across a larger partition on all four physical drives. • The user data volume is configured as a four drive RAID 5 array which is a multi disk
striping with parity check array.

HDD FAILURE MODES SUMMARY
When a disk drive fails on a MaxAttach NAS 4000 Series, the actions of the system BIOS and the operating system (O/S) vary depending on the drive that failed. In general, by following the procedures in this section, you should at least be able to get your system reboot.
n If the failed drive is the main boot drive, the OS will attempt to switch to another bootable drive.
n If any of the other drives fails, the O/S will keep the system running and re-bootable and the user data available.
n In both cases above, the RAID array is said to be in a “Degraded” where any additional disk failure will lead to user data loss.
DETAILED HDD FAILURE MODES
Table #1 - Disk Drive Failure Modes
Failed Drive Below
System Boot Disk / Remedial Action Required Primary Master Drive 0 PM-D0 Primary Slave Drive 1 PS-D1 Secondary Master Drive 2 SM-D2 Secondary Slave Drive 3 SS-D3 Primary Master Drive 0 Fails 1. Three boot attempts from PM-D0. 3. Replace PM-D0 and restore mirror from SM-D2
2. Recovery boot from SM-D2
Primary Slave Drive 1 Fails
1. Normal boot from PM-D0
2. Replace PS-D1 and restore mirror from SS-D3
Secondary Master Drive 2 Fails
1. Normal boot from PM-D0
2. Replace SM-D2 and restore mirror from PM-D0
Secondary Slave Drive 3 Fails
1. Normal boot from
PM-D0 2. Replace SS-D3 and restore mirror from
PS-D1
For four failure modes above, the general restoration procedure is: 1. Remove the unit from its rack; 2. Replace the failed drive; 3. Identify the new disk with a write signature; 4, Upgrade the new disk to a dynamic disk, 5. Reconnect the new disk to its mirror image; 6. Rebuild the RAID 5 array.
For the failure mode below, no physical disk replacement is required. Instead, the O/S partitions on the Master Drives must be re-imaged.
Primary Master Drive 0 & Secondary Master Drive 2 O/S Corrupted 1. Three boot attempts from PM-D0 5. Restore O/S to PM-D0 from mirror on SM-D2
n A Fatal Error (“blue screen of death”) may be encountered during the reboot tries on the Primary Master Drive 0.
• The error message will probably be INACCESSIBLE BOOT DEVICE. • The system will remain locked up for five minutes. It will then attempt to reboot
automatically from the Primary Master Drive 0 three times. If this attempt fails, the system will reboot from Secondary Master Drive 2.
n If a successful boot is obtained, the RAID array is now in “critical state” and can tolerate the loss of no additional disks without permanent user data loss.
n The system will continue to boot from the Secondary Master Drive 2. Failure Sequence for Primary Slave Drive 1 (PS-D1)
n The BIOS marks the drive as missing (“bad”).
n The BIOS will boot normally starting from the Primary Master Drive 0.
n If a successful boot is obtained, the RAID array is now in “critical state.” The loss of another disk drive will lead to permanent user data loss.
n The system will continue to boot from Primary Master Drive 0. Failure Sequence for Secondary Master Drive 2 (SM-D2) n The BIOS marks the drive as missing (“bad”).
n The BIOS will boot normally starting from the Primary Master Drive 0.
n If a successful boot is obtained, the RAID array is now in “critical state.” The loss of another disk drive will lead to permanent user data loss.
Failure Sequence for Secondary Slave Drive 3 (SS-D3) n The BIOS marks the drive as missing (“bad”).
n The BIOS will boot normally starting from the Primary Master Drive 0.
n If a successful boot is obtained, the RAID array is now in “critical state.” The loss of another disk drive will lead to permanent user data loss.
n The system will continue to boot from Primary Master Drive 0.
