scope of this
paper
The purpose of this document is to provide instructions for replacing hard drives in hp systems,
particularly during circumstances where multiple drive replacement is desirable.
Additionally, this document focuses on Microsoft’s utility DISKPART to expand the drive.
“Expanding” refers to the action of increasing the size of a volume to obtain more usable
space; e.g. increasing a 200GB drive “F:” to 300GB. Other utilities are available and should
be used according to their respective instructions.
Factors that can contribute to a situation where multiple drive replacements might be desirable
include:
•
Mixed Ultra2/Ultra3 environments where there is a desire for a single drive platform.
•
Mixed drive speed environments (10K RPM/15K RPM) where there is a desire for a
single drive platform.
•
Upgrading Array Subsystem to larger capacity drives
Whatever the reason for effecting multiple drive replacements, this document is designed to
outline a process for effecting those replacements. Two replacement methods are
documented—one for when the drive(s) to be replaced are in a protected set (RAID 1, RAID 5
or ADG) and the other for situations where the drives are unprotected (RAID 0 or JBOD) or
when there is a concern that multiple drives in a protected set could fail concurrently.
Note: Throughout this document, the term TARGET DRIVE is used to refer to any drive
targeted for replacement per these instructions.
overview
Replacing multiple hp hard drives requires specific methods. Factors that can contribute to a
situation where multiple drive replacements might be desirable include:
•
Mixed Ultra2/Ultra3 environments where there is a desire for a single drive platform.
•
Mixed drive speed environments (10K RPM/15K RPM) where there is a desire for a
single drive platform.
•
Upgrading Array Subsystem to larger capacity drives.
Two replacement methods are documented—one for when the drive(s) to be replaced are in a
protected set (RAID 1, RAID 5 or ADG) and the other for situations where the drives are
unprotected (RAID 0 or JBOD) or when there is a concern that multiple drives in a protected set
could fail concurrently.
The purpose of this document is to provide instructions for replacing hard drives in hp systems,
particularly when multiple drives in a given system need to be replaced at the same time.
First Method. The first method assumes that any drive needing to be replaced is a member of
a RAID 5, RAID 1, or ADG set such that the removal of a single drive from the array should not
result in the loss of data or of the array. This method involves removing a TARGET DRIVE,
replacing it, and allowing the array to rebuild to the replacement drive. The process is repeated
until all TARGET DRIVES in the array have been replaced. Should a drive fail during the
rebuild process, data may be lost requiring that the array be restored from backup media. It is
important, therefore, to assess the condition of all the drives in the array prior to beginning this
process. An ADU report would be the best tool for this purpose.

Second Method. The second method should be used in any situation where it is known that
the removal of a single drive would result in loss of data (RAID 0, JBOD), or if there is a
sufficient number of TARGET DRIVES in an array that would make the first method described
inconvenient or too time consuming. Another factor that should be considered is the statistical
fact that as the number of TARGET DRIVES in an array increases, the odds of a drive failing
during the rebuild process also increase. With this method, all TARGET DRIVES would be
replaced at the same time and each logical drive would need to be restored from backup
media.
IMPORTANT: For either replacement method, insure that you have current, known good, full
backups from which you could restore the logical drives where the drives are being replaced.
HP recommends that at least two (2) such backups are available and that one of them be
moved off-site.
Both methods include steps to upgrade array controller firmware and to apply the Monitoring &
Performance (M&P) Patch to the hard drives. You should have the appropriate firmware and
patch files available before beginning either process.
helpful
information for
hard drive
replacement
In an NT or Windows 2000 environment, the array controller firmware can be flashed remotely
while the system is online, though the system will require a reboot for the new firmware to take
effect. In a NetWare or Linux environment, the array controller must be flashed from a diskette.
In either environment, the M&P Patch must be applied from a diskette.
Instructions for remote ROM flash can be found here:
http://www.hp.com/support/files/server/us/webdoc/ROM/BestRemoteROMUsers-001.pdf
Note: The following links and firmware revisions were current at the time this document was
written (October 2001). Check hp’s website (http://www.hp.com/support/files/) for more
current firmware before proceeding.

Remote flash firmware (v 1.30) for the SA4200 controller is here:
http://www.hp.com/support/files/server/us/download/9893.html
Note: a more recent firmware rev (v 1.44) is available if you can flash from diskette.
To upgrade the firmware from diskette (v 1.72 for the SA5300 and v 1.44 for the SA4200):
http://www.hp.com/support/files/server/us/download/10633.html
IMPORTANT: DO NOT USE this method if the drive to be replaced is NOT a part of a RAID
5 (data guarded), RAID 1 (mirrored), or ADG (Advanced Data Guarding) set. Furthermore,
insure that there are no degraded or failed drives in the set.
Verify that all logical drives in an array are configured for RAID 5, RAID 1, or ADG. Logical
drives that are not redundant and drives that are part of a RAID 0 set will not rebuild after
TARGET DRIVES are replaced.
This method should only be used if the drives to be replaced are not reporting a significant
number of errors, which may indicate a greater likelihood of drive failure (an ADU report can
be used to determine current error counts). Since ANY drive could fail at ANY time, Step 1
below CANNOT be skipped.
It is assumed that you know the physical position of the TARGET DRIVES within the arrays. If
not, then you should generate an ADU report prior to starting this process (for NT and Windows
2000 environments) or during this process (for NetWare and Linux environments). Instructions
for generating the ADU report (which may help you identify TARGET DRIVES) are at the end
of this document.
perform the
following steps:
1. Perform backups - INSURE THAT YOU HAVE CURRENT, KNOWN GOOD, FULL
BACKUPS FROM WHICH YOU COULD RESTORE THE ARRAY(S) IN WHICH DRIVES ARE
BEING REPLACED. HP RECOMMENDS THAT AT LEAST TWO (2) SUCH BACKUPS ARE
AVAILABLE AND THAT ONE OF THEM BE MOVED OFF-SITE. This is a precautionary
measure in the event of a drive failure during the rebuild process.
2. Set the array controller’s Rebuild Priority to High – Using the Array Configuration
Utility, verify that the array controller’s Rebuild Priority is set to High (the default is Low). If
the Rebuild Priority is not set to High, then change and save the setting.
3. Document array and partition configuration information – In the event of a failure that
would require you to rebuild the array, redefine logical volumes or partitions and restore
from backup media as you may need this information.
4. Upgrade array controller firmware - Flash the array controller(s) in the server with
the latest firmware available for the controller.
5. Generate an ADU report for the server (if you don’t already have one) – The ADU
report can be generated by booting the server with the SmartStart CD and running the
Array Diagnostic Utility or it can be done from within Windows NT or 2000 with ADU
1.50 or greater. Detailed instructions are provided at the end of this document.

6. Apply the Monitoring & Performance Patch – Refer to the URLs provided earlier in this
document for information about this patch.
7. Restart the system – Allow the system to restart.
8. Remove one of the TARGET DRIVES and allow it to completely rebuild before
moving to the next drive. – Refer to the ADU report to verify which drives in the array are
TARGET DRIVES. If your array is configured with a Hot Spare, and the Hot Spare is a
TARGET DRIVE, then replace the Hot Spare first. Using your ADU report, use the error
counts, if any, to prioritize the order of drive replacement, replacing the drive(s) with the
highest error counts first. Instructions for reading error counts in the ADU report are at the
end of this document.
array
expansion
a. Remove the TARGET DRIVE.
b. If your array is configured with a Hot Spare, the array will immediately begin to
rebuild to the spare (unless the drive you’re replacing is the Hot Spare). The new
drive can be inserted at anytime. This will terminate the spare rebuild process and
will immediately initiate the rebuild process on the new drive. The controller will
flash the online LED at approximately once per second on drives that are in the
process of being rebuilt. There are also online utilities that will indicate the status of
the logical drives and arrays and will display the completion percentage of the
rebuild process. For Netware, this utility is CPQONLIN.NLM and for Windows, it
is ACU. For Linux, ACU will need to be run from the SmartStart CD.
c. Insert the replacement drive. After locking the drive lever, insure that it is fully
seated by firmly pressing the drive in. The array will begin to rebuild as soon as
the drive is spun-up and tested. (If a spare was allowed to rebuild completely, data
will now be copied directly from the spare to the replacement drive).
d. WAIT until the online LED has stopped blinking and is on solid, indicating the
rebuild process has completed. The status can also be checked with ACU or
CPQONLIN. Note that multiple logical drives may exist on the same array of
drives; so wait for all logical drives to finish rebuilding at which point the Online
LED on the replacement drive will be on solid.
e. Repeat steps 8a through 8e until all TARGET DRIVES have been replaced.
If, for some reason, you encounter a multiple drive failure or if the array fails to properly rebuild
resulting in loss of the array and loss of data, then you will need to follow the instructions for the
second method, Multiple, Simultaneous Drive Replacement, which follows.

method 2 multiple,
simultaneous
drive
replacement
This method must be used for any drive that is not a member of a RAID 5 (data guarded), RAID
1 (mirrored), or ADG (Advanced Data Guarding) set. It is optional for drive replacement within
a RAID 5, RAID 1, or ADG set and should be considered as an alternative to Method 1,
particularly if it is believed that drives to be replaced are at a high risk of failure. This method
is also intended as a way to recover in the event that Method 1 fails due to multiple,
simultaneous drive failures.
If you are replacing drives that contain the system volume, you will need to re-install your
operating system and backup software before restoring your data. Therefore, you might want
to consider replacing drives that contain operating systems with Method 1 or obtain a disaster
recovery backup utility that will allow you to restore after booting off a floppy, bootable CD, or
bootable tape. Be sure that you have any required distribution media, device drivers, license
keys, etc. at your disposal before beginning.
It is assumed that you know the physical position of the TARGET DRIVES within the arrays. If
not, then you should generate an ADU report prior to starting this process for NetWare and
Linux environments or during this process for NT and Windows 2000 environments. Instructions
for generating the ADU report are at the end of this document.

IMPORTANT: This method requires that you restore your data from backup media. DO NOT
replace any drives before verifying the completeness and reliability of your backups.
1.
Perform backups - INSURE THAT YOU HAVE CURRENT, KNOWN GOOD, FULL
2.
Document array and partition configuration information – Document the array
configurations(s) and partition/volume information. This information may be needed to
redefine the array after replacing drives and will likely be needed to redefine logical
partitions and/or volumes.
3.
Upgrade array controller firmware – Flash the array controller(s) in the server with the
latest firmware available for the controller.
4.
Generate an ADU report for the server (if you don’t already have one) – The ADU
report can be generated by booting the server with the SmartStart CD and running the
Array Diagnostic Utility, or it can be generated from within Windows NT or 2000 with
ADU 1.50 or greater. Detailed instructions are provided at the end of this document.
5.
Shut down and power off the server and THEN power off all external storage.
BACKUPS FROM WHICH YOU WILL RESTORE THE DRIVES AND/OR ARRAY(S) IN
WHICH DRIVES ARE BEING REPLACED. HP RECOMMENDS THAT AT LEAST TWO (2)
SUCH BACKUPS ARE AVAILABLE AND THAT ONE OF THEM BE MOVED OFF-SITE. This
is a precautionary measure in the event of a drive failure during the rebuild process.

6.
Replace the TARGET DRIVES – Using the ADU report, identify and remove the TARGET
DRIVES and install replacement drives. As you remove the drives, it may be helpful to
label each one with its location in case there is some reason you need to reinstall the
drives as they were.
NOTE: If you ARE NOT replacing one or more drives in the system volume (OS volume), then
skip to Step 10, Configure array(s) (No OS installation performed).
Rebuilding the Operating System (OS) drive – The next few steps should be
performed if you are replacing one or more drives on which the OS is installed. As a
result, you will need to reinstall the OS after replacing those drives. If you want to
perform a SmartStart installation of the OS, then you’ll need to run the System Erase
Utility as part of the process, otherwise, SmartStart will always boot to the System
Utilities window.
If you plan to perform a SmartStart assisted OS installation, continue with Step 7.
If you do not plan to perform a SmartStart installation of the OS and instead plan to perform
the OS manufacturer’s standard install, then skip to Step 9, “Configure array(s) and install the
OS (OS manufacturer’s standard installation.”
7.
Run the System Erase Utility – (SmartStart assisted OS installation only) -
THE SYSTEM ERASE UTILITY WILL DESTROY ALL DISK PARTITION INFORMATION FOR ANY
ATTACHED HARD DRIVE. It will erase internal drives, external drives, drives attached to all
Smart Array controllers, drives attached to any dumb SCSI controllers and any Fibre attached
drives.
DO NOT APPLY POWER TO ANY EXTERNAL STORAGE ENCLOSURES UNTIL INSTRUCTED
TO DO SO.
In steps 7a and 7b below, you are asked to unseat certain hard drives. If you choose to
physically remove drives from their slots, be sure to mark them so that you can return them to
their original positions when asked to reseat them in a later step.
a.
IF THE OS IS INSTALLED TO THE SERVER’S INTERNAL DRIVES:
All external storage enclosures should be powered off. Do not apply power to any external
storage enclosures until instructed to do so.
•
b.
Any internal hard drive that is not being used for the operating system
should be unseated at this time.
IF THE OS IS INSTALLED ON DRIVES EXTERNAL TO THE SERVER:
All external storage enclosures should be powered off. Do not apply power to any external
storage enclosures until instructed to do so.
7
•
Unseat all of the server’s internal hard drives.
•
Unseat any external drives not being used for the operating system.
•
Apply power ONLY to the external enclosure that contains the OS. All
other external enclosures should remain powered off.
c.
Apply power to the server and boot to the SmartStart CD.
d.
You may get an “Array not configured” error message with a prompt to press F10
for system partition utilities or F1 to continue. Press F1 to continue.

g.
Reseat (or replace) all hard drives that were unseated (or removed) in Steps 7a and
7b.
Configure array(s) and install the OS (SmartStart assisted OS installation) – This
step assumes that drives in the OS partition have been replaced and that you are
reinstalling the OS using a SmartStart assisted installation and that you have just
completed Step 7, “Run the System Erase Utility – (SmartStart assisted OS installation
only).”
a.
Apply power to all external storage enclosures.
b.
Apply power to the server and boot to the SmartStart CD. You may get an “Array
not configured” error message with a prompt to press F10 for system partition
utilities or F1 to continue. Press F1 to continue.
c.
Perform a SmartStart installation of your OS. When the Array Configuration Utility is
run, use the documentation you created in Step 2 to redefine any arrays as required.
d.
Skip to Step 11, “Apply the Monitoring & Performance (M&P Patch).”
Configure array(s) and install the OS (OS manufacturer’s standard installation) –
This step assumes that drives in the OS partition have been replaced and that you are
reinstalling the OS per the manufacturer’s standard installation process. If you don’t
need to reinstall the OS, skip to Step 10 (Configure array(s) (No OS installation
performed). If you need to reinstall the OS but plan to use a SmartStart assisted
installation, you’ll want to follow the instructions in Steps 7 and 8.
a.
Apply power to all external storage enclosures.
b.
Apply power to the server and boot to the SmartStart CD. You may get an
“Array not configured” error message with a prompt to press F10 for system
partition utilities or F1 to continue. Press F1 to continue.
c.
From the System Utilities window, run the Array Configuration Utility. Use
the documentation you created in Step 2 to define any arrays that were lost
as a result of drive replacements. Exit the ACU when finished.
d.

Configure array(s) (No OS installation performed) – You should be performing this
step if you’ve just completed Step 6, “Replace the TARGET DRIVES” and did not need
to reinstall your OS.
a.
Apply power to all external storage enclosures.
b.
Apply power to the server and boot to the SmartStart CD. You may get an
“Array not configured” error message with a prompt to press F10 for system
partition utilities or F1 to continue. Press F1 to continue.
c.
From the System Utilities window, run the Array Configuration Utility. Use
the documentation you created in Step 2 to define any arrays that were lost
as a result of drive replacements. Save the configuration and exit the ACU
when finished.
IMPORTANT NOTE: At this point the following should be true:
•
You have replaced all of your TARGET DRIVES (Step 6).
•
Your OS is installed (either you didn’t need to reinstall it or it was reinstalled in Steps
7 and 8 or in Step 9).
•
All arrays are configured (Steps 7 and 8 or Step 9 in the case of an OS
reinstallation, Step 10 otherwise).
•
All system components (external storage enclosures and server) are powered up.
If any of these statements is not true, please review the steps taken and return to this point
when the statements are true.
11.
Apply the Monitoring & Performance (M&P) Patch - Insert the M&P Patch diskette
and reboot the server. Follow the on-screen instructions for the patch.

generating an
ADU report
Generating the report and identifying TARGET DRIVES
An ADU report provides a wealth of information relative to the configuration and health of the
array(s) and drive(s). Model number, serial number, firmware, error counts, etc. can use it to
identify array controllers and drives. The ADU allows you to save the report it generates to a
text file for analysis and documentation.
For NT and W2K servers, download the latest Array Diagnostics Utility (ADU). This version of
the ADU can be run from each server while the server is online. For NetWare and Linux
servers, shut down the server and run the ADU by booting from the SmartStart CD and
selecting the ADU icon.
Once the ADU is loaded, select File, Save data, and choose all array controllers. You will be
prompted to insert a diskette in drive A:. If running the ADU from the SmartStart CD, you will
need a diskette to save the report. For NT and W2K servers you will have an opportunity to
change the location of the report file. In either case, click OK at the prompt for a diskette.
You will be prompted for the path and filename to which the report will be saved—enter a
valid path and filename and click OK. You will then be presented with a dialogue box where
you can enter comments that will be saved at the top of the report. You should enter the
system name here for later identification.
Samples from various portions of an ADU appear on the following pages.
