Poliant ML370G5 array rebuild problem.

Hi all,
i'm experiencing a weird problem on 4 servers as in subject.

In each server there are 2 controllers SmartArray P400 with 512 MB of cache, the controller in slot 1 manages drives from 1 to 8 of the first cage (140GB 2.5" SAS 10K), the controller in slot 5 manages drives from 9 to16 of the second cage (140GB 2.5" SAS 10K).
On the first controller there is configured array A (raid 5 of 7 disks plus spare) with 2 logical drives, on the second controller there is configured array B (raid 5 of 7 disks plus spare) with 1 logical drive.

If i detach a drive on the first cage the spare disk comes online and the rebuild begins and ends correctly.

If i detach a drive on the second cage the spare disk doesn't come online and the server sops responding via O.S. forcing me to power it down. When i power it on again the automatic rebuild starts and ends correctly.

All the server have been updated to the latest firmware available with Maintenance CD 7.91.

Thanks in advance.

hi J. T. Kirk

yes I would say yes it's weird in 4 servers same condition.

all of them are Windows or linux? mix?

let me ask you which firmware you have in those controller? 4.06 or 4.12?

I supposed you have the latest drivers also? 7.91 also?

Re: Poliant ML370G5 array rebuild problem.

Hello Karlo,

on these 4 server the O.S. running is VMWare ESX 3.0.2 with HP MGTM Agents 7.9.0.

The firmware on the controller is the one included in HP Firmware maintenance cd 7.9.1 (4.06).

Seeing that you wrote 4.12 i searched more deeply and i found the additional 4.12 firmware for the maintenance CD, i think i'll try the update.

Thanks for the suggestion.

I'll keep you updated on the results.

Best regards, JTK.

Hi all,

unfortunately the problem still persist even with P400 firmware 4.12, same behaviour, the array B is rebuilded automatically only after the powerdown and powerup of the server.

As you can see the log starts with the rebuild and not with the failure of the disk because as soon as i unplug one disk from the second cage the server locks up.

I'll try even the upgrade of the BIOS of the server which is not the last one, i'll keep you updated.

Re: Poliant ML370G5 array rebuild problem.

Sad update.
Flashed the BIOS to varsion 11/13/2007.
First rebuild after reboot runs correctly, after it finishes, if i unplug a whatever drive from cage 2 locksup the server and no logs are produced.

Re: Poliant ML370G5 array rebuild problem.

Hi all,
unfortunately i'm not able to solve the problem, i moved the controller from slot 5 to slot 4 but the problem still persists.

When the controller stops working there is the LED ID 1(CR14: Controller lockup LED) on.

Has anyone further suggestions?

Thanks in advance.

Re: Poliant ML370G5 array rebuild problem.

hi

did you resolved this issue?

I got 2 workarounds, but first maybe you already fixed it

Re: Poliant ML370G5 array rebuild problem.

Hello Karlo,

i haven't fixed the problem yet, but i'm 99%sure that it is HW problem on the controller.

I changed the controller with a p400 with 256 MB of cache and the problem did not show

My next step is to ask for replacement of SA Controller, if the solution is confirmed i'll proceed asking for replacement of the other 3 SA Controller.

However i'd like to know about the workaround you mentioned.

Best regards, JTK.

Re: Poliant ML370G5 array rebuild problem.

hi

mmm you have done an important finding already

well this because some days ago someone had a similar issue you're having ... rebuild process did not come up when it should so it's up to you if you want give it a try

I hear two ways but I have not had the time to test second one

first:
power off server
remove HDDs from second controller
Use/reboot with SmartStart CD (SSCD)
go to maintain server and use erase utility with HDDS out.
Power off server
insert HDDs again

second (not tested yet)
power off server
Remove HDDs from second controller
So it is using SSCD again
Go to maintain server
Open Array configuration utility (ACU)
Erase the Array B/Logical Drive.
Power off server
insert HDDs again

Re: Poliant ML370G5 array rebuild problem.

Hello Karlo, what you said is really interesting, it could avoid to open 4 RMA, i've to find the time to try it on a standby server.
I'll keep you updated.

Re: Poliant ML370G5 array rebuild problem.

Hello Karlo,

i first tried the 2nd solution but without disks inserted it's not possible erase the array configuration.

I tried 1st solution also but the problem was still there.

I'm opening a RMA call.

Thank you very much for your support.
