Hi all
I have just realised that my lpar can only see through one path to the storage server.

fget_config –A shows:

---dar0---

dac0 ACTIVE dacNONE ACTIVE
hdisk2 dacNONE
hdisk3 dac0
hdisk4 dacNONE
hdisk5 dac0
hdisk6 dacNONE
hdisk7 dac0
hdisk8 dacNONE
hdisk9 dac0

I have run rmdev –Rdl dar0, fcs0, fcs1, dac0 and checked the host port information on the storage server is the same network address returned by lscfg –vl fc0 and fcs1. I then run cfgmgr again but I still get the above.

This is the sixth lpar on the frame and lslpp -l | grep devices.fcp* shows that the firmware level is the same as the other lpars (running aix 5.3) but I do not have this problem with any other lpar.

Any ideas please?

Thanks

Hi there

Have you checked your storage zoning and lun masking ? Check to ensure that you have defined both HBA's on the storage and created zones containing the HBA's and controllers.

I generally configure one HBA to one controller (ds4000)

Hi steevojb

Thanks very much for the tip. You were right on. I had made some changes to the effective configuration on the two SAN switches and even though they both had the same ports in the zones, there was a minor difference... I have now enabled the same configuration on both switches and I am now seeing the other controller as well.

Best regards

Hi Steevojb,

This is jatin chawla here. I am also facing the same problem. From your reply I have checked the zoning and storage part also. It is also perfect and with both the HBA's. Still I am getiing the same error.

Also, I am unable to see 'dac1' as a device like 'dac0'. How can I get the same. I have done rmdev dar0,dac0,dac1,fcs0,fcs1 and even reboot the server also. But no effect. And the same LUN is visible to another LPAR. since both LPARs in cluster. Please tell me the solution for the same.

Have anyone found a solution for this? I have the same problem and couldn't find a proper documentation about this anywhere..
