EVA Disk disconnecting

Hi,

 

I've got a BL685 G6 Server running Windows Server 2008 Enterprise R2 with Service Pack 1.  It has MPIO V4 installed.  The servers has a QMH2462 FC card installed and is connected to an EVA8100.

 

We are having issues with 1 EVA disk which disconnects every 7 days or so, Can see all other disks in the Management Console apart from this 1 disk.  The errors in the Event Log are below:

 

All paths have failed. \Device\MPIODisk11 will be removed.

A fail-over on \Device\MPIODisk11 occurred.

 

Any ideas

Re: EVA Disk disconnecting

I just came across this kind of issue at customer site. This is caused by issues in Windows 2008 mpio.sys. Please check the following KB articles...
