hp BL20p-G3 with EVA4100 one failed MPIO path

Hello,

 

I have a BL20p G3 server with Qlogic QLA2312 dual port HBA connected to an HP EVA 4100 with EVA DSM MPIO software installed. One of the four paths in MPIO DSM Manager is shown as failed. Windows 2003 R2 SP2 is installed on the BL.

 

We have upgraded the Qlogic driver to the latest version 9.1.3.18 and MPIO to 4.01.01 , Qlogic FW is 1.45, it changed to good for an hour then showed one of the paths as failed again.

 

Another server in the enclosure has also the same issue while other servers does not have any problem: all paths are OK.

 

Notice that access from the servers with one failed path to the EVA is normal but we square and ask why this failed path.

 

Please help.

Re: hp BL20p-G3 with EVA4100 one failed MPIO path

Hi,

What are the positions of these two blades with failed path?
Do you have the possibility to move the blade? Same problem then?
What kind of interconnects do you have in the blade enclosure?

Hi,

 

Both servers are in the same enclosure and the failed path is the fourth one; please find the hpdsm output from one server:

For information, the left SAN switch 4GB SAN in the p-Class enclosure is connected to the left 8GB SAN switch in a C7000 enclosure and the right one of p-class is connected to the right one in the C7000; so, we have configured two fabrics (right and left).

 

Both EVA 4100 controllers are connected to both fabrics.

 

Thanks.
