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.

How to determine the current version of firmware on the hard drive

 

 

 

  • For MCS-7825-I4 and MCS-7828-I4, running Cisco UCM 7.1 and above, you can use the CLI command 'show hardware' to verify the firmware version.

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.

If you had tried the original firmware update on a 7816 and it didn't work there has been a new one posted that will.  The links in the document all point to the new one.

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.

I got the same issue, but I'm already to the hard disk firmware 3b05 from factory.

I did the recovery disk and found no errors.

After restart, i'm good for 20-24 hours and then the system goes in read-only file system.

Any other things to try before a full reinstall ?

Thanks

Please gather all of the information outlined in the document and open a TAC SR so that we can get your information over to IBM.

Beginner

I already open a TAC and told me to rebuilt/re-install the server and do a restore.

Any chance of this issue affecting Cisco Unity Connection as well?

Cisco Employee

Any chance of this issue affecting Cisco Unity Connection as well?

This issue can hit any of these servers.  We haven't seen it on Windows-based Unity but have on UC, CUP, and CUCM.

Beginner

Finally I did a full rebuilt of my CUCM and it's stable now.

Cisco told me a new hard disk firmware upgrade should be out very soon to fix that issue.

Unfortunately I have the same problem on my Cluster of two 7816I4 with CUCM6.1

For the 7816s the first thing you should do is reboot the server and hit F2 during POST.  This will get you into the drive's self diagnostic application.  If that report shows a failure then you need to replace the hard drive.

Edit: Looks like the F2 option was removed from these servers.  We are looking for the replacement utility and the doc will be updated when it is known.

For your issue running the CLI command you are hitting the 3rd bug listed in the Releated Defects above (CSCtg26203).  You can run the bootable DSA or open a TAC SR to use a workaround.

"replace the hard drive" - So it is not useful to upgrade the firmware?

Which HDD is recommended by cisco?

"replace the hard drive" - So it is not useful to upgrade the firmware?

Which HDD is recommended by cisco?

If you have a faulty hard drive then upgrading firmware will not help.

The HDD replacement needs to go through Cisco TAC if you have an MCS server.  If you bought the server directly from IBM then you need to contact their support to arrange a replacement drive.  If you do not have a support contract on the server from IBM or Cisco then the IBM part number for the drive is listed on the IBM server solutions page at www.cisco.com/go/swonly.

Beginner

There is no way with F2 during POST to get into the drive's self diagnostic application.

We bought the MCS7816I4-K9-CMB2 with CUCM6.1 preinstalled.

Can it be that the Dynamic System Analysis (DSA) is not preinstalled for this machine?

Is it the only way to take the ibm_fw_dsa_3.10_anyos.iso?
