error encountered on the HOST

Hello All ,

This is my first post here :

I am getting this error from the HP-UX 11i v3 (11.31) Host  connected to Brocade DCX Backbone

vmunix usdadspsbduh0 lun path (class = lunpath, instance = 123) belonging to LUN (default minor = 0x1a) has gone offline.

What could be the issue ? could this be a zoning issue ? Please advice !


                           Vendor ID is = 0x1077

                           Device ID is = 0x2432

            PCI Sub-system Vendor ID is = 0x103C

                   PCI Sub-system ID is = 0x1705

                               PCI Mode = PCI Express x4

                       ISP Code version = 4.2.2

                       ISP Chip version = 2

                      Previous Topology = UNINITIALIZED

                             Link Speed = UNKNOWN

                     Local N_Port_id is = None

                  Previous N_Port_id is = None

            N_Port Node World Wide Name = 0x5001438002ae1fd5

            N_Port Port World Wide Name = 0x5001438002ae1fd4

            Switch Port World Wide Name = 0

            Switch Node World Wide Name = 0

            N_Port Symbolic Port Name = usdadsps_fcd1

            N_Port Symbolic Node Name = usdadsps_HP-UX_B.11.31

                           Driver state = AWAITING_LINK_UP

                       Hardware Path is = 0/4/0/0/0/0

                     Maximum Frame Size = 2048

         Driver-Firmware Dump Available = NO                                                                                                                                               

         Driver-Firmware Dump Timestamp = N/A

                         Driver Version = @(#) fcd B.11.31.0803 Jan 20 2008

Appreciate if someone can take a look.

Re: error encountered on the HOST

Usual suspects --  portCfgFillWord, cabling, SFP.

For a better answer I'd need to have a look at portShow <hostport#>, to start with.

Zoning is unlikely because (1) you've seen the LUN and (2) this looks like a link-level problem.

Re: error encountered on the HOST

Hello Linar,

Thank you for looking into it -

Port status looks good to me , though .Is it with the Host itself , HPUX hosts 're know to log out from time to time .

Also, there isn't any SAN storage going to -5001438002ae1fd4

Re: error encountered on the HOST

well then,

next up, you're running rather old driver version. Consider upgrading to the current release, B.11.31.1103 (but mind possible kernel patch dependencies too).
