Data Domain - Connectivity Issues

vblather

I am new to Stor2rrd and am trying to implement a Data Domain for monitoring.  So far:

Allow access from the Stor2rrd host to the storage on port 22 = success

Create user stor2rrd under user role on the storage = success

Exchange public keys = success

Logon to the storage and add key = success

Test connection ssh <data domain host> -l stor2rrd = does not fail, but requires a password.  I give it the password for the stor2rrd user I created earlier and it logs me on. 

Configure storage in etc/storage-list.cof = success

Test storage connectivity = fails.  Output below:

[lpar2rrd@stor2p1s1 stor2rrd]$ ./bin/config_check.sh DDRP1S4
tee: /home/stor2rrd/stor2rrd/logs/config_check.out: Permission denied

=========================
STORAGE: DDRP1S4: DATADOMAIN
=========================
TCP connection to "172.31.0.48" on port "22" is ok
ssh -o ConnectTimeout=80 -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o SendEnv=no -q stor2rrd@172.31.0.48  "system show all"
  connection failed!!

[lpar2rrd@stor2p1s1 stor2rrd]$ ./bin/config_check.sh 172.31.0.48
tee: /home/stor2rrd/stor2rrd/logs/config_check.out: Permission denied

Any thoughts or ideas would be greatly appreciated as I'm new to the product but it seems to hold great promise.

ls -l /home/stor2rrd/stor2rrd/logs/config_check.out

ls -ld /home/stor2rrd/stor2rrd/logs

I looked at config_check.out.  It contains the following: 

=========================
STORAGE: DDRP1S4: DATADOMAIN
=========================
TCP connection to "172.31.18.94" on port "22" is ok
ssh -o ConnectTimeout=80 -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o SendEnv=no -q stor2rrd@172.
31.18.94  "system show all"
  connection failed!!

The logs directory contains the following files:

[lpar2rrd@stor2p1s1 logs]$ ls -lia

If I check error.log-DDRP1S4 it is full of either "command failed:" or "file not found:" errors.

Any thoughts?

under root:

rm /home/stor2rrd/stor2rrd/logs/config_check.out

su - lpar2rrd

cd /home/stor2rrd/stor2rrd

./bin/config-check.sh DDRP1S4

Thanks for your quick reply.  Here is the output of those commands:

Found it!!!

It was all me.  I was getting the SSH keys from the stor2rrd server, then going to the datadomain console with a different SSH session, logging in, then entering the keys.  There were no errors but I needed to be logging into the data domain console FROM the stor2rrd server.  Continuing on and will update

Pavel

exchange properly ssh key as per docu:

All four Data Domains and now populating the web gui.  Thanks for all your help.
