Re: Can't get Data path Failover working ...

Hi Arnaud,

Have you double and triple-checked that the key you entered in was correct *and* the hex chars are in lower case (I think that's the right way around)? Note that you can configure all of your valid drives at once, instead of individually, to support DPF with "/usr/lpp/Atape/instAtape -a".

Subject	[ADSM-L] Can't get Data path Failover working ...

Hi List, I'm trying to activate the data path failover feature we bought with our brand new 3584 library (12 LTO3 drives), without success ... O.S. is AIX 5.3.0.0 ml 02.- Atape driver is at 9.6.0.0 The actual (test) setup looks like : 6 drives are connected thru fcs2 and fcs3, the other ones thru fcs4 : fcs2 Available 06-08 FC Adapter fcs3 Available 09-08 FC Adapter fcs4 Available 0A-08 FC Adapter rmt1 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt2 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt3 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt4 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt5 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt6 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt7 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt8 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt9 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt10 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt11 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt12 Available 0A-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt13 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt14 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt15 Available 06-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt16 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt17 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt18 Available 09-08-02 IBM 3580 Ultrium Tape Drive (FCP) The zoning on our Cisco MDS has been defined so that both FCS2 and FCS3 are able to see the first 6 drives (therefore 18 drives are seen by the system) Following IBM's Redbook "implementing IBM tape in UNIX systems - sg246502", I have installed the DPF license key : dpf_keys Installed dpf keys: values = "xxxxxxxxxxxxxxxx" (hidden to protect the key) Now , each time I try to enable DPF for a drive, I get following error : chdev -l rmt1 -a alt_pathing=yes Method error (/etc/methods/chgAtape): 0514-018 The values specified for the following attributes are not valid: Feature Code 1681 License key not found for Alternate Pathing Feature Run dpf_keys -a key to install a license key Anyone having an idea of what I'm missing ? Thanks in advance ! Regards.
