IBM Storage V7000 unreachable in stor2rrd after Code Upgrade of IBM (Level 8.4.0.2 (build 152.23.21)

kutz

Hello Xorus Team,

please explain below - trying to reach ourt from stor2rrd server to recently upgraded IBM Storage System (V7000).

Check does not work - if I pick out the commandline from check_script which is executed - it works passwordless.

Login via ssh commandline directly works.

But: Check asks for Password - why?

Hi,

1. do you have defined an ssh identity file in storage properties? is not it DSA?

2. you can try to switch to password authentification (latest stor2rrd 7.10+)

kutz

Regarding 1: yes - it's rsa

Regarding 2: I'll give it a try and keep you posted.

kutz

My fault - dsa Keyfiles have been implemented - I switches to rsa and this works.

Thnaks for you support.
