Need help with Storwize v3700 setup

in IBM

Hello, I'm having trouble with initial config. I've deployed the virtual appliance from OVF and have it running.

I followed the steps on this page http://www.stor2rrd.com/IBM-install.htm and everything has worked, until I reach the point 'Test the storage connectivity'.

When I run ./bin/config_check.sh (I am SU'ed to lpar2rrd) I get the error below. I created the ssh keys while su'ed to lpar2rrd as well. Not sure what I did wrong? I'm pretty sure I followed the instructions carefully. Please help.

    what about:
    chmod 600 /home/lpar2rrd/.ssh/id_rsa*
  • mykl_74
    mykl_74

    OK that eliminates the key file warning. Now when I run ./bin/config_check.sh it asks me for the password for the lpar2rrd acct on the v3700. It fails if I use blank password. I flip to the v3700 and set a password on the act, and then it will authenticate.

    Then it asks for the key password, which is blank: Enter passphrase for key '/home/lpar2rrd/.ssh/id_rsa.pub':

    Then I get connection ok. But only if I use the password for the acct on the v3700.

    you have probaly generated ssh key with pasphrase. it is wrong.
    in the docu is  stated: Type enter instead of passphrase

    If this is the case then you have to repeat whole procedure.
    delete existing key, use ssh-keygen and import it to the storage (delete the user account there and create it again with proper ssh key)

    I thought so too, and I re-ran the ssh keys command 3 or 4 times before posting with no luck.

    Are there supposed to be SSH keys in the home dir for a newly deployed VM from OVF? I re-created the VM today from the ovf, and when I checked the lpar2rrd home folder (before running ssh-keygen) there were already key files there - id_rsa & id_rsa.pub. I renamed them to .bak, and ran the ssh-keygen commands again and this time everything worked fine.

    ssh keys of lpar2rrd user are created automatically on its 1st start. It should work .. .
