How do you monitor the health of a mirrored disk in Windows?
I have a Mirrored Dynamic disk on my Windows 2003 Server. How do you monitor the health of the volume?
Is there a way to have the server send an email when there is an issue with the volume? Is there a way to have the server run S.M.A.R.T. tests?
EDIT: Nothing says WTF like logging into a client server, running DISKPART LIST VOLUME and seeing this.
Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 X xDrive NTFS Mirror 233 GB Failed Rd
Volume 1 C NTFS Simple 57 GB Healthy System
Volume 2 D DVD-ROM 0 B Healthy
Volume 3 F RAW Partition 466 GB Healthy
Volume 4 E New Volume NTFS Partition 932 GB Healthy
Solution 1:
I had the same question a while ago. The first thing I thought of was using WMI, but for some weird reason, WMI doesn't expose the health of a RAID volume through any of the normal Win32_* classes.
I eventually stumbled across the script in this article and made a few modifications to suit my requirements. It parses the output of diskpart.exe's "LIST VOLUME" command. This may seem a little dirty and ugly, but right now its the best option I've seen.
The script as it appears on the linked page is ready to be used with Nagios / NSClient++. If you know a bit of VBScript it's easy enough to modify this to send e-mail instead of printing status information.
If you don't know VBScript, I'll gladly give you a modified version which will do whatever you want it to.
Solution 2:
for /f "tokens=4,9 delims= " %a IN ('echo list volume ^| diskpart ^| find "SSD"') do echo %a %b
Replace find "SSD" with "mirror"(or stripe... whatever) or your volume name. (my volumes are named SSD1 + SSD2)
Stick in a batch file with @echo off and ur done. :)
@echo off
for /f "tokens=4,9 delims= " %%a IN ('echo list volume ^| diskpart ^| find "SSD"') do echo %%a %%b
Above line is needed for batch. =)
Notes
- You need to have a volume name for this to work, else change tokens to
tokens=8

Smartmontools (http://sourceforge.net/apps/trac/smartmontools/wiki) has a windows version, but I don't know it runs on 2K8
Solution 4:
I use this ugly batch file to monitor more than one hundred servers to check mirror status and the result is lovely. It is a nsclient++ client plugin to do passive check every four hour to send result to nagios server.
check_mirror.bat
@echo off
echo list volume | diskpart | find "Mirror" > H
for /f %%i in ('type H ^| find /c "Mirror"') do set /a M=%%i
for /f %%i in ('type H ^| find "Mirror" ^| find /c "Health" ') do set /a H=%%i
for /f %%i in ('type H ^| find /c "Risk"') do set /a risk=%%i
@del H /q
rem echo M=%M%, H = %H% Risk=%risk%
if %risk% GTR 0 goto err
IF %M%.==0. goto nomirror
IF %M% EQU %H% goto mirrorok
:err
echo CRITICAL: Something Wrong.
exit /B 1
:mirrorok
echo OK: Mirror Health.
exit /B 0
:nomirror
echo OK: No Mirror Found.
exit /B 1
