Failed Redundancy on ML370

I am not a computer guru and have inherited this server system.I have a ML370 with 6 x 9.1 Hot Swap drives connected to the Integrated Dual Channel Wide Ultra 2 SCSI Controller(port 2).The platform is Windows 2000 Advanced Server. Configuration is as follows: 2 x 9.1 HDD are mirrored with the system volume and 3 x 9.1 HDD are configured with a RAID 5 data volume. 1 x 9.1 HDD is assigned a hot swap spare.Windows Disk Management reports that 1 HDD of the RAID 5 array is (Failed Redundncy) and it also reports that the 1 HDD hot swap spare has also (Failed Redundancy). How do I correctly fix this. I have 2 new 9.1 HDD to replace them. Do I replace the failed hardware, then right click the failed RAID-5 volume set(marked as Failed Redundancy) and choose Repair Volume? or do I go through the SCSI controllers BIOS utility upon reboot? I am not even sure if this controller supports RAID-5 at the hardware level. I also checked the event logs, which do not report any hardware failure.I humbly appreciate any suggestions. Thank you.

Re: Failed Redundancy on ML370

Joseph can you tell if you see any amber/red Led at front of HDD?
Also can you upload Integrated Management Log Viewer actual log?
Additionally make second Upload for Array Diagnostic Utility?

If HDD connected to Array controller â you can swap them on the fly, if to Onboard which is would be strange in your Configuration as long you see Online spare â there must be Array Controller, possibly Integrated Smart Array Controller (ROC) with two channels. Run ADU report

Re: Failed Redundancy on ML370

I don't have a smart array controller. I am certain of that. From what it looks like the Windows 2000 server OS disk management has a mirrored system HDD's 0&1 and a RAID-5 with Data HDD's 2,3,4. HDD #5 is just available as backup but NOT marked as a hot spare. Sorry wrong choice of words. It's only a dynamic disk and unallocated.Used for a standby spare. There were only amber lights lit on HDD 4 and 5. I right clicked disk 4 and selected "remove disk", then replaced the hdd and choose "repair volume". Volume regenerated and reported as healthy. Removed disk command for disk 5 and replaced with a new hdd.I changed disk 5 to dynamic and unallocated. Disk mangement reports that the RAID-5 is healthy, but both new disks still show amber led's and the green led hdd icon still lit at the same time. How do I remove the amber led's on the disks and only show green led's.Is there a way to confirm that the RAID-5 data has integrity? TIA.

Re: Failed Redundancy on ML370

Can't tell exactly if Software RAID have an effect on the LED status â possibly
When you replaced HDD had you restart server? Or done on the fly?

Re: Failed Redundancy on ML370

First, thank you for your help. I replaced both HDD on the fly. After repairing the volume on HDD#4 and the led did not change status, I restarted the machine, which still had no effect. What would you suggest?

Re: Failed Redundancy on ML370


If possibly run firmware CD
http://h18023.www1.hp.com/support/files/server/us/download/23331.html
In your case it could be firmware, cable or SCSI backplane circuit

Optionally you can verify if latest Driver used, which is probably yes.
There was few instances where LED amber can be ignored, as long you see drive healthy from software.

Re: Failed Redundancy on ML370

Joseph, is there any chance that you can test previously removed HDD if they really failed?

Re: Failed Redundancy on ML370

I cannot test the old hdds, however I did replace them with 2 new hdd of the exact same make and model. The storage controller is "Integrated dual Channel Wide Ultra2 SCSI Adapter". Is that considered a Smart Array Controller? If so what utilities do I install to support it?The Disk Management shows the RAID-1 volume and the RAID-5 volume as "healthy". The original installation appears to be installed with only the Windows 2000 Server OS only,no other utilities. Their are no signs of utility ASR partitions, nor any other vendor utilities. Yikes! What have I gotten myself into!!! I downloaded the firmware cd and burned the image. I plan to use this first. Let me know your feedback, I appreciate it.

Re: Failed Redundancy on ML370

I checked the device manager and it shows: Adapter SCSI Card 29160N -Ultra160 SCSI, and Compaq Integrated Dual Channel Wide Ultra SCSI Controller. I hope this helps.

Re: Failed Redundancy on ML370

Joseph probably you should ignore LED

copy
IMPORTANT: The term "degraded status" in these utilities does not refer to hard drives that have been failed by the controller. If a hard drive is failed by the controller (it mean smart array), the amber "failed" LED will illuminate, indicating that the drive should be replaced.

also for 160 adapter

or

ASR option from F10 if System Partition Installed, SCU (System Configuration Utility used to create that or Smart Start CD. From disk manager you should see 36MB partition if Utility F10 Installed.

If you have where to make a good backup take your chance to purchase from eBay SA 3200 (They usually sold for $10-$15), your Server is G1 ML370 beige? After make a HW raid and restore data. Or if you can find ROC Chip Integrated smart Array Controller from eBay
http://partsurfer.hp.com/cgi-bin/spi/showphoto?partnumber=158855-001

If you decide to use smart Array Controller - run M&P patch from advisory

Re: Failed Redundancy on ML370

BTW: Joseph no point's assignment needed at this point, we not completely sure if that would be case where it can be completely ignored.

Re: Failed Redundancy on ML370

I took your suggestion and bought a used Compaq Smart Array RAID, 158855-001, 16MB chip off of Ebay. You're correct it's a ML370 1st Generation and Beige. Besides sticking the this RAID chip in the motherboard. Could you possibly point me to some documentation for me to study to set this hardware raid up, as well as the monitoring software to install this correctly. I want to do this correctly,the way it's suppose to be done.I have decided to back the whole enchilada up and restore the data once the correct Monitoring software is installed for this hardware RAID. TIA.

Re: Failed Redundancy on ML370

Install RAID Chip, if you not done with firmware run additionally Firmware CD any of 7.x (same link for smart start 5.5)
http://h18004.www1.hp.com/support/files/server/us/subscription/ssdownloads.asp

First step run Erse Utility when HDD connected to Array Controller
1. http://h18007.www1.hp.com/support/files/server/us/download/17918.html
2. Run F8 from POST to configure Array (ROC should be at 1.50 firmware) and SCU http://h18007.www1.hp.com/support/files/server/us/download/13227.html
3. Or Use Smart Start CD there will be choose of Manual Install it will install F10 Partition and than launch ACU (Array Config. Utility)
4. When System Partition and Array Configured you can run direct O/S Install
5. After O/S Installed run PSP 7.30 it will install all COMPAQ stuff
http://h18023.www1.hp.com/support/files/server/us/download/22272.html

During O/S Install SNMP and Configure them prior running PSP, similar to
