Inquire on Solaris 10 showing duplicate entries for same tape device

Well I thought I would start here.  First off, don't know Networker what's so ever.  I work for HP and support the virtual Tape library being presented to the the Networker SAN servers.

In some cases, the inquire command will return duplicate device for the same tape device, or 2 entries for the same device, Same LUN and /dev/rmt file, just a different target ID.

The Fiber HBA's are Emulex 8 GB HBA's and they are using the native Solaris fiber driver, (Leadville).  The problem can occur on any one of the Networker SAN backup servers.

Below is an example:

                                           WWNN=62AF9B49DB680060200000000000C0D5

scsidev@4.8.0:HP      Ultrium 3-SCSI  R210|Tape, /dev/rmt/408cbn

                                           S/N: d9CW.ORs0v

                                           ATNN=HP      Ultrium 3-SCSI  d9CW.ORs0v

                                           WWNN=62AF9B49DB6800601F0000000000C0D5

scsidev@4.10.0:HP      Ultrium 3-SCSI  R210|Tape, /dev/rmt/410cbn

                                           S/N: d9CW.ORs8v

                                           ATNN=HP      Ultrium 3-SCSI  d9CW.ORs8v

                                           WWNN=62AF9B49DB6800601F0000000002C0D5

scsidev@4.12.0:HP      Ultrium 3-SCSI  R210|Tape, /dev/rmt/410cbn

                                           S/N: d9CW.ORs8v

                                           ATNN=HP      Ultrium 3-SCSI  d9CW.ORs8v

                                           WWNN=62AF9B49DB6800601F0000000002C0D5

Notice that the last 2 devices are really the same device/

cfgadm -alv -o show_FCP_dev show correct number of devices.

Any ideas?

Hi Julian

Please post the driver version and the FW version in the Emulex card.

Re: Inquire on Solaris 10 showing duplicate entries for same tape device

Are you using some sort of multipathing?  To check if those are two entries (really) for the same drive, test them with mt.  I haven't work with Solaris much lately, but I remember that in old days numbering used to star from 0.  In your case is 400+.  Unless you use custom names (like /dev/rmt/{bus}{target}cbn then I wouldn't be surprised if device database might have gone banana.  Without any further test to test few potential scenarios, it would be hard to say what it is.  I would start by testing if I get the response on both device names if case I load the tape.  If yes, it means both device names are valid and this might be due to multipathing.

hi nearlinegeek

have you checked the zoning? also, do you do port or node zoning?
