AIX LPAR all vscsi adapters not showing

Hi,

One some of our AIX LPARS which are vio clients, we do not see all the vscsi adapters in LPAR2RRD. Looking in the data directory for the LPAR I see

-rw-r--r--    2 lpar2rrd staff             1 Jun 25 07:31 san-vscsi4.cfg
-rw-r--r--    2 lpar2rrd staff       3825736 Jun 25 09:29 san-vscsi4.mmm

-rw-r--r--    2 lpar2rrd staff       1913208 Jun 25 09:29 san_resp-vscsi6.mmm

but vscsi5 and vscsi7 are missing. How do I get lpar2rrd to pick up the other vscsi adapters please ?

  • Hi,

    are these adapters listed in below output?

    iostat -Dsal 10 1

  • Hi,

    on the VIO side:


    cd /var/tmp
    ls -ltr lpar2rrd*
    tail lpar2rrd*err
    tail lpar2rrd*txt   # 3 files will be there, use the one without "ps" and "fs" in its name

    place outpu here of send it to us via support@lpar2rrd.com
  • On further investigation it appears that all the vscsi adapters from one VIO server are missing from every lpar. The last entry in the ".err" file was May 22nd. The following is the last line from the agent.txt as requested

    As you can see vscsi5 & vscsi7 are missing

    Another check shows that this seems to be across many lpars.
    Looking at the output of "iostat -Dsal" it appears that the vscsi output is split across 2 sections, not together and the client parsing is only picking up the last entry  e.g.
    Vadapter:                        xfers                                 read                        write                              queue              
    -------------------- --------------------------------------- -------------------------- -------------------------- --------------------------------------
                           Kbps   tps bkread bkwrtn partition-id   rps    avg    min    max   wps    avg    min    max    avg    min    max   avg   avg  serv
                                                                         serv   serv   serv         serv   serv   serv   time   time   time  wqsz  sqsz qfull
    vscsi3                  0.0   1.5    1.5    0.0            2   1.5   2.4    0.0    0.0    0.0  51.4    7.0   10.6    7.1M   0.0    0.0    0.0   0.0   0.0


    Vadapter:                        xfers                                 read                        write                              queue              
    -------------------- --------------------------------------- -------------------------- -------------------------- --------------------------------------
                           Kbps   tps bkread bkwrtn partition-id   rps    avg    min    max   wps    avg    min    max    avg    min    max   avg   avg  serv
                                                                         serv   serv   serv         serv   serv   serv   time   time   time  wqsz  sqsz qfull
    vscsi2                  0.0   4.8    4.8    0.0            3   4.8   2.3    0.0    0.0    0.0  27.4    7.0   10.6    2.5M   0.0    0.0    0.0   0.0   0.0


    So only vscsi2 is picked up. I'll continue to check this

  • Hi,

    can you send us complete iostat -Dsal 60 1
