ontapdsm mpio problem


We have installed Data ONTAP® DSM 3.5 for Windows® MPIO on DPM Windows 2008 R2 server.

After reboot there were no more FCP PARTNER MISCONFIGURED errors on the netapp storage.

In Windows Logs/ system we get next errors:



Event ID:61123

General description: IO error. SRB status: Timeout reported on Lun 3 on path Id 05000001. The IO will be retried.

Please see the attachement.

Does anyone has a clue, how to solve this problem?

Thank you!

With regards,

Hi Klemen,

I had the same issue. It was caused by a bug in the ONTAP version 8.1. After an upgrade to 8.1.1P1 the issue no longer appears.

Kind regards


Re: ontapdsm mpio problem

Do you happen to have the bug ID for that?

Re: ontapdsm mpio problem

I have a customer with the same problem and an SFP on the SAN switch turned out to be the problem.

Re: ontapdsm mpio problem

Having the same issue at two different locations have replaced SFP's and warning still occurs.

Hi There,

I have had a similar issue come up after ONTAP upgrade to 8.1.4P2 from 8.1.2P4.

The environment is pretty much the same, see below:

- FAS6240HA

- ONTAP 8.1.4P2 (7-Mode)

- FC SAN environment

- NetApp SAN Host Utilities Kit v6.0.2

- ONTAP DSM v3.4 - upgraded to v4.1 since the issue.

- Microsoft Windows Server 2008 R2 (MS Cluster)

- SQL Server the main application used on this Microsoft Cluster.

The error I am getting is:

IO error: SRB Status Command timeout reported on LUN 6 on Path Id 03000101. The IO will be retried.

and also repeated on other LUNs

Any help would be appreciated.
