dl360 g5 p400i SAS mirror "inconsistent stripe"

I am working with HP's ISS Solution center on this one as well.

Install this server last week and am up-to-date with latest drivers/firmware(8.2 cdrom)/service packs as of Monday, Aug 25.

I am receiving an "inconsistent stripe"
from Cissesrv (see below). 2 mirrored drives (146gig 10k SAS)

Anyone else see this? know how to resolve it? I sent an offline adu-report.zip to HP, which they said was AOK (other than the missing battery but one does not come with this model...we are only using Read only cache)



Event Type: Warning
Event Source: Cissesrv
Event Category: None
Event ID: 24607
Date: 8/28/2008
Time: 5:21:36 AM
User: N/A

Description:
The event information received from array controller [Embedded] was of an unknown or unrecognized class.

An excerpt of the controller message is as follows: Inconsistent stripe, LDrv=0 LBA=0x00081B100-0x00081B1FF.

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

hi again

even downgrade this

HP ProLiant Smart Array SAS/SATA Event Notification Service for Windows Server 2003/2008

since it's the source -- CISSESRV --

Ah! good suggestions.

The server was brand new and running for 4 days and you are correct...I only received this error after the 4th day, which was my upgrade day.

That day, the Controller firmware was -not- upgraded but the Controller Driver, Hard Drive Firmware and the Storage Event Notification Service were upgraded.

This message has only appeared 3 times: 1st time about 30 minutes after the 1st reboot after all the upgrades were done. Then 3 days later it appear twice within the same second at a very quiet time for the server 5:16am

I did run the full offline HP Insight diagnostic on the drives last night and it came back clean.

I will scrape some time this weekend to try at least the Driver downgrade and the Cissesrv downgrade.

thx!

yes sometimes installing latest updates give us new messages - most of the time - phantom messages so downgrading is the option

OK try that and let us know

bye

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

what was the solution to this? I have just upgraded a dl380 g5 with proliant support pack 8.10 A after which I received this error. The P400 card fw remained the same (latest).
Is this error a problem?

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

I was seeing this error about every other day after upgrading to lastest PSP and Firmware.

I only downgraded:

HP ProLiant Smart Array SAS/SATA Event Notification Service for Windows Server 2003/2008

(per Karlo's suggestion). I did this downgrade on Sept. 3 and have not seen the error since. I will post again in another couple of days as I watch the event log.

I did not have to reboot after this downgrade. The installation will stop and start the service.

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

This event can occur following any unexpected power loss or server reset during host write operations. The inconsistency is only detected by Smart Array's background Surface Analysis (auto-reliability monitoring), and the event will continue to be reported on subsequent boots until the specified LBA range is ultimately overwritten by the host. Has the server ever been reset or lost power during write operations? Are the same LBA range(s) reported as being inconsistent each time the system is rebooted, or do they differ each boot?

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

Just a few more comments:

If the event always indicates a consistent LBA range and if there's no easy way to re-write this LBA range under the OS, another way to repair the inconsistency is to break and then re-sync the mirror pair (using offline ACU), or by manually hot-removing one of the drives from the mirror pair and reinserting (allowing it to rebuild).

Note that this event is more likely to be reported following an unexpected power loss/reset during writes if the controller's posted-write cache is disabled (such as in this case when there are no batteries). If the controller's battery-backed posted write cache was enabled, any write data held in the cache would automatically be written to BOTH drives after the power is restored, maintaining consistency between the mirrored drives.

1)Server reset/lost power during write?

Not too my knowledge. Server is only a couple weeks old. I have always done a clean shutdown.

2)Are the same LBA ranges being reported?

Most ranges are different, last 2 times they were the same.

This Controller has no battery...so no write cache.

Warnings appeared after upgrading PSP/Firmware.

Have not rebooted in 8 days.

It was suggested to downgrade CISSERV. That was done on Sept 3. No Warnings occurred until Sep 8 and Sept 9 (single warning each day)

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

HP is sending a new controller out.

Any tips on the best steps to get the drives on the new controller?

--backup data
--Down server
--Remove power cords
--Antistatic myself
--open server
--remove orig controller
--install new controller

Now this is where I can use some pointers.

The Server will come up with an error about an unconfigured array/controller, correct?

I am assuming I should boot with SmartStart and get into the offline ACU.

The 2 146-gig SAS drives are mirrored...

What are the best steps to take in the ACU so I don't lose my current data and the drives get mirrored on new controller? Just nervous about having to rebuild the entire OS and Apps.

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

hi

so issue continued?????


best practice

- yes backup data
- power off server
-- Antistatic myself
- remove power cable
- take the old controller out
- insert the new controller
- reconnect controller cables
- plug server and done

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

yes, the issue is continuing despite the downgrade of CISSESRV service.

Last note from HP on my Case # is that they are sending out a new controller card.

"- plug server and done"

Is it that straight forward? New controller will mirror the drives without needing the ACU? No data loss?

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

yes

the RAID information is ketp in the HDHD RIS
RIS = Raid Information Sector

so you just replace controller and you're done.

in case you need to take your HDDs out put tham back in the same position

The new controller was put in early Friday morning with no problems and the old one shipped back to HP.

There have been no errors in the past 3 days. I need to wait a few more days since the old controller did go 5 days between warnings.

If it goes warning-free the rest of this week, that will be a pretty good sign that the problem is gone.

No warnings since the new controller card was installed.

Looks like that fixed it. We are running just fine now

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

What happened to all the replies to this thread? I was watchnig this as I have the same issue on 6 servers (out of 6 I might add) and there were comments upto 21st Jan 2009?

I have had the P400 replaced on 3 of my systems and I still get the errors but I guess any "inconsistant stripes" will still be there. Am I right in thinking that new card + 5.22 firmware and then rebuild the array to get rid of the erros is the way forward? Or will this still produce problems?

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

peeky

no if you want the errors go away use firmware 4.12

but they are not errors just false messages

Interesting, I was following the thread, too, and remember that there were plenty of replies recently. I'm not sure where they went.

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

Maybe HP removed them to make the problem look like it went away on it's own :-)

Thanks for the reply Karlo, will I run into problems if I just downgrade the firmware on it's own, or do I need to downgrade anything else too?

Thanks,

Peeky

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

Indeed.... they removed a lot of replies, including mine....

Re: dl360 g5 p400i SAS mirror "inconsistent stripe"

Peeky, That was my suspicion, too.

For what it's worth, I don't get the errors with the firmware downgraded from 5.22 to 4.12. My Smart Array SAS/SATA Event Notification Service for Windows Server 2003/2008 is at 6.8.0.32, which I believe I was also asked to downgrade from 6.10.0.32 when I was working with HP, but since I did it at the same time as the firmware downgrade, it's not clear to me whether it's strictly necessary.
