NetApp 7-mode ssh cipher issue

If you get error "no matching cipher found. Their offer: 3des-cbc" during running config_check.sh like below:

./bin/config_check.sh 7mode-alias
  =========================
  STORAGE: 7mode-alias: NETAPP/7MODE
  =========================
  Connection to "7mode-alias" on port "22" is ok
  Connection to "7mode-alias" on port "443" is ok
  ssh -o ConnectTimeout=80 -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o SendEnv=no -p 22 stor2rrd@gvepss0020  "?"
  Unable to negotiate with 192.168.1.1: no matching cipher found. Their offer: 3des-cbc
  SSH connection failed!!!

Solution

3des-cbc cipher required by the storage is weak and insecure.
Despite of that you have to allow it on stor2rrd server:
su - stor2rrd # lpar2rrd on the Virtual Appliance
echo "Host *" >> ~/.ssh/config
echo "    Ciphers +3des-cb" >> ~/.ssh/config
And try again storage access, it should go through now:
./bin/config_check.sh 7mode-alias
