Load issues after upgrade to 6.10

edited October 8 in LPAR2RRD
Hello,

After upgrade to 6.10 on server and client, we were facing issues regarding comunication with the server, in all lpars except one. Also it was consuming CPU with lscfg command.

We reinstalled rpm on clients, restarted processes, restarted xorux server and the issue persist.

Can you help me with this?

Thanks in advance,

  • Hi,

    we are trying to get volume UUID via
    lscfg -vl  <disk name>

    Ho long does it run from command line?


  • Yes I saw that command in ps - ef executed by lpar2rrd, randomly in all disks. but we have a lot of disks, i.e 9665 disks in 1 lpar.

    The issue was during 24hs so I decided to downgrade to 6.02 to avoid CPU consumption on production machines. This version is working properly.
  • Hi,

    the agent gets all disk UUIDs.
    it is something we will need in the near future for mapping disks between storage/server (lpar/vm)

    It runs every hour.
    We have just change it to once a day. Would that be still unacceptable for your env?
    10k disk devices is really quite huge numbers, I have never seen that.
    I am affraid that even once a day it is something what can make problems :(

    As s workaround would be skipping that on some parameters.

  • I've never had issue with any version. It just happens with 6.10. 
    So the UUID was get without issues in version 6.02

    We have 5 lpars with the same configuration, but worked in 1 lpar. The others had 'agent timed out after : 50 seconds'  message.

    It was "hanged" during a day until I change version



    consuming high CPU



    Yes, 10k hdisks is a crazy thing. Veritas multipath generate that number of devices. The server has 600 disks.

  • 6.02 and olders do not get UUIDs, it is was introduced in 6.10
