Summary

Cisco Media Convergence Servers 7816-I4, 7825-I4 (and IBM x3250-M2  equivalent) and 7828-I4 have recently been experiencing technical issues.  These servers are used by Cisco Unified Communications Manager and various other Cisco Collaboration software products.

The symptom is that the local disk drives' file-system goes into read-only mode, which can manifest as application services going down, the server becoming  unresponsive via the network or the management interfaces, or worst case data corruption necessitating a reinstall and restore from backup.

 

Root cause has been identified by Cisco and its suppliers as a disk drive issue stemming from interaction with system firmware. 

 

Field Notice 63374 has been published and includes more technical details regarding this  issue.  Cisco and its suppliers are committed to high quality and  apologize for any disruptions or impact caused by this issue.

 

Solution

The file-system going read-only issue which has recently been affecting server models MCS-7816-I4, MCS-7825-I4, and MCS-7828-I4 (or their IBM equivilants) in the field is addressed by CSCti52867 - "IBM 7816-I4 and 782x-I4 READONLY file system".

 

The fix for CSCti52867 is now available and requires the application of two patch files.  Install both of these patch files in the order listed below.

 

1. First install ciscocm.ibm-diskex-1.0.cop.sgn 
     The Readme file ciscocm.ibm-diskex-1.0.cop.sgn includes installation instructions for this .cop.sgn.

     Make sure to only install this utility when show hardware CLI output indicates the array is in a healthy state.

     If your server has never had the filesystem go readonly then this step is optional. 
2. Next install Cisco-HDD-FWUpdate-3.0.1-I.ISO .
     The Readme file Cisco-HDD-FWUpdate-3.0.1-I.Readme.pdf includes installation instructions for this ISO.

     This installer is completely independant of the OS installed on the server.

Note:  Installing the FWUpdate v3.0(1) or later will get you firmware with the fix for this defect.  It is always recommended that you apply the latest FWUCD available for your server.

 

Refer to the Release Note of CSCti52867 and the Readme file for each of the above mentioned patch files for more details.

 

Symptoms

  • The file system goes READONLY, then CUCM services may go down, the server may become "unresponsive" meaning that it is not possible to ssh into the server, login to the console, or web into the server although it may still respond to pings.
  • Traces from all services stop writing (including syslog)
  • You see the following error on the server console
 
EXT3-fs error (device sda6) in start_transaction: Jornal has aborted

 

 

 

 

 

  • If you are able to login to the server via SSH, the following output may be displayed.

The text highlited in red are the info you need.  This output shows a server with two drives with model  number WD2502ABYS on 3B04 firmware.  These drives should be upgraded as  soon as possible.

 

  • For MCS-7825-I4 and MCS-7828-I4 models running Cisco UCM versions previous to 7.1, as well as any version of Cisco UCM running on a MCS-7816-I4 model server, you must download and boot off of a CD burned with Cisco-HDD-FWUpdate-3.0.1-I.ISO (refer to the "Solution" section for links to download the ISO and readme).  Upon successful boot of the Cisco-HDD-FWUpdate-3.0.1-I.ISO CD, you will be presented with the current HDD FW version as well as the opportunity to upgrade to HDD FW version 02.03B06.

What should be done if filesystem issues persist after applying the patches?


As of 16 February 2011 if you encounter any further filesystem or hard drive issues after applying both the firmware and disk exerciser you should proceed to replace the affected drive(s).

 

There are three ways you can replace the drive(s).

  1. If you have an MCS server with an active Cisco support contract open a TAC service request.
  2. If you purchased the IBM x3250 M2 MCS equivalent and have an IBM support contract contact IBM support.
  3. If you do not have any support contract for the server you can purchase a new drive from Cisco or IBM.
    • The Cisco part number for the hard drive is HDD-7825-I4-250=.
    • Contact your IBM reseller to confirm the correct part number for the 250GB SATA simple-swap HD for the x3250 M2 server.

 

If you have any questions you can leave a comment on this document. The ibm-fs-failure@cisco.com email address is no longer active as of 1 September 2014.

Sending the email will not generate a TAC SR but will allow us to collect more information.  This is an informal submission with no associated SLA and we will make every effort to follow up submissions but cannot guarantee a response.

Bad news.  While applying the cop.sgn file it completed on step 14 of 20 (that's a big problem).  The system went into read-only mode <ARG>.  I had already applied the firmware upgrade as the cop.sgn file wasn’t there when I downloaded the .iso file for the firmware.

Should I try and reapply the cop.sgn file again?

Cisco Employee

Cam,

Please try step 2a (boot from CUCM recovery CD to run filesytem check).

Boot from the CUCM recovery disk and select option f to check the filesystem.   

  • If you do not have a recovery disk you may download the ISO from the Software Center on cisco.com. You should always download the latest version of the recovery disk regardless of the CUCM version running on the server.

If no errors reported, then reboot server and from AdminCLI run "show hardware".  Confirm that the "Status of volume" is "Okay".  If the status of the volume is in resycing state, then wait until the status transitions to "Okay".  Then run ciscocm.ibm-diskex-1.0.cop.sgn again.

At the end of the day, I will get new HDDs from IBM in case of the "CSCti52867 - IBM 7816-I4 and 782x-I4 READONLY file system". I could really believe that there is an old firmware inside...

So, do you recommend that I install the new firmware before I begin the full installation?

The old HDD of MCS6816-I4 has firmware 02.0, I don't know which will have the new one.

An upgrade from 02.0 to "Cisco-HDD-FWUpdate-3.0.1-I.ISO" is possible and no problem?

I will do the upgrade/installation process tomorrow, so it would be nice to know the way till then...

(I have to travel thourgh half of Germany for that, so it have to be successful)

Beginner

Shane,

Because we have already received an additional hard disk from IBM due to this issue I upgraded the firmware to 3B06 and then tried to run the DSA, it still failed regardless of what version I use.  I have now been informed by Cisco TAC that is isn't a hardware issue and to proceed with the install, to note I am installed 6.1.4.

What concerns me is should the server fail again I won't be able to run the DSA so I won't be able to know whether there is a hardware issue or not.  I am now installing this software on the HD which doesn't have the latest firmware on so will see what happens.  Do you still recommend installing this firmware upgrade anyway?

Also if running the upgraded firmware is it required to install the ciscocm.ibm-diskex-1.0.cop.sgn ???

I did notice when I was running the cop.sign file previously that it was in resyncing state (showed it while booting up).  I have verified the file system using the recovery disk and all is well and everything is ok.

I'll retry the cop.sign file tomorrow night as I've got other tasks gonig on tonight.  I'll let you know how it goes at that point.

You might want to update the readme on the cop.sign file that it mentions about the resyncing state so others don't have the same issue.

Thank you for your help.

Yes, you should install both ciscocm.ibm-diskex-1.0.cop.sgn & Cisco-HDD-FWUpdate-3.0.1-I.ISO.  After running both utilities try running the DSA again.  Is this MCS-7816-I4?  Please ensure that all of the information requested in this doc has been uploaded to your TAC SR and send your SR number to ibm-fs-failure@cisco.com

Cisco Employee

Cam,

If the cop.sgn install fails again, collect the "Event Viewer-System Log" and "Install and Upgrade Logs" via RTMT covering the time of the installation and upload them to your TAC SR.  Then send an email to ibm-fs-failure@cisco.com indicating such.

Shane,

Well after upgrading the HD firmware I then installed 6.1.3 and then upgraded this to 6.1.4.  At the final part where it asks you for any configuration via an xml file I click on continue and it does nothing!

I have tried this twice and at both times at gets stuck.  I have also been advised by IBM because of the issue with the DSA to install disk controller firmware as this could be the problem, however when I try to run this via http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=TOOL-BOMC and create a boot iso this also fails!

I'm going to try once again to install 6.1.3 and then upgrade via the gui but i'm not confident this will make a difference at all!!

This document talk about server under linux-based server, but what happen for the Windows-based servers like Cisco UCCX or Cisco Unity ?

I have numbers of these server in my customers, I meet 2 time this bug on CUCM, but I am afraid to see it on UCCX and UNITY server, which are windows based...

This is a very good question.

I don't think we've seen it yet on any Windows based system.  My personal guess is because Windows doesn't respond to the underlying hardware issue or timeout in the same way Linux does.  The filesystem going readonly is the OS' way of protecting itself in response to an issue with the disk subsystem.  Windows may not have a similar protection mechanism.

Has there been any new findings on this? I would love to be able to disregards this for the few servers I have in the field using UCCX. But I can not justify this based on a guess. Thanks!

Cisco Employee

There have been no reports of server models affected by this issue (MCS-7816-I4, or MCS-782X-I4) experiencing this issue when running Windows based operating systems.

Marcus,  the new/replacement HDD that you receive from IBM will NOT be running the new firmware version 3B06 which is the fix for this issue.  Also note that revision "02.0" is NOT the full firmware version.  The full firmware version (ex. 02.03B0X) will be displayed once you have booted the server with the "Cisco-HDD-FWUpdate-3.0.1-I.ISO".  And the installation of this patch file will update the FW to 02.03B06.

Yes, you can install "Cisco-HDD-FWUpdate-3.0.1-I.ISO" before installing the Cisco UC application on this server.

networkdefence,

On an MCS-7816-I4 in the lab I just now performed the following steps with success:

1. Ran ciscocm.ibm-diskex-1.0.cop.sgn (took ~40min)

2. Booted from a Cisco-HDD-FWUpdate-3.0.1-I.ISO CD which indicated that the current HDD firmware was 02.03B02

3. Proceeded to install the new 02.03B06 HDD firmware successfully with the  Cisco-HDD-FWUpdate-3.0.1-I.ISO CD.

4. Ejected the  Cisco-HDD-FWUpdate-3.0.1-I.ISO CD and replaced it with a Standalone DSA 3.0.2 CD.  Then selected the option to reboot the server.

5. The server booted via the DSA 3.0.2 CD and I was able to execute the "Hard Drive: Self Test" on "/dev/sda" as per step 1c documented in this article.  And the test completed successfully.

If you are still having issues after you current efforts, then please give these 5 steps a try.  And if the server still exhibits problems, please update your TAC SR accordingly.  Also ensure that all of the information requested in this doc has been uploaded to your TAC SR and send your SR number to ibm-fs-failure@cisco.com

Cam,

If the cop.sgn install fails again, collect the "Event Viewer-System Log" and "Install and Upgrade Logs" via RTMT covering the time of the installation and upload them to your TAC SR.  Then send an email to ibm-fs-failure@cisco.com indicating such.


It worked flawlessly this time.  I've rebooted the server and will now watch and see.  I should know within 8 days max if it solves my issue since it seemed to crash every 5 to 7 days.  Again, thanks for the help.

I did the upgrade for the brand new IBM HDDs with 02.03B05 to 02.03B06. You can only see the long name of firmwareversion with that "Cisco-HDD-FWUpdate-3.0.1-I.ISO". With DSA 3.20 I could only see 02.0

All Servers are new installed.

Well, we will see how it works...I hope good.

Thank you for your help!
