LUN presented successfully but OS does not see them

[NavyYard]

Hi!

I have HP EVA 6000 storage System connected to Blade 860i running HP-UX 11.31.

I have created host, virtual disk folder and virtual disks  with correct WWN that I matched with output from HP-UX server (fcmsutil):

fcmsutil /dev/fcd4

 N_Port Node World Wide Name = 0x5001438021de45d1
 N_Port Port World Wide Name = 0x5001438021de45d0

Driver state = ONLINE

fcmsutil /dev/fcd5

N_Port Node World Wide Name = 0x5001438021de45d3            

N_Port Port World Wide Name = 0x5001438021de45d2

Driver state = ONLINE

Driver Version = @(#) fcd B.11.31.1303 Dec 10 2012

ISP Code version = 5.6.5
ISP Chip version = 2

I created virtual Disks folder and created virtual disks and presented LUNs to the host without errors.

On HP-US, I ran insf -e to re-create devices successfully but I do not LUNs presented to HP-UX when I do "ioscan -funC disk"  or  "ioscan -m dsf".

From command View EVA, I can see port node and devices are presented to the correct server wwn.

syslog.log does not show any device created after presentation.

I have repeated this process on other similar blades successfully, but this is being a problem child.

Any advice will be really helpful.

Thanks

Is the zoning configured correctly, you can check it in the switch using fcping

#fcping <HBA wwpn> <EVA wwpn>

Did you set the host mode to hpux?

Did you present/unpresent and present the LUN again?

In such case the system will not provide access for security reason, most simple solution is a reboot. Otherwise you can override this setting using scsimgr.

Hi Torsten!

Thanks for the reply.

When I created host on EVA, I picked HP-UX as OS and picked WWN that corresponds to "N_Port Node World Wide Name".

I had rebooted the system too, but I did not see LUNs presented to OS.

Thanks

But you should present to the port WWN.

All!

I unpresented/represented the lun and rebooted the server, this resolved my problem and i am able to see all the luns I presented to the server.

Thanks to all who advised on this issue.
