Automatically Adding Host Credentials to 7MTT via Batch File

It’s a “feature” of 7MTT (every version), that when your 7MTT server reboots, or when you restart the “NetApp 7-Mode Transition Tool” service, you lose all the cached credentials and have to re-input them. This is a bit of a pain if you’ve got lots of hosts in 7MTT. It’s doubly a pain since 7MTT (from 2.0 I think) schedules the 7 to C SnapMirror transfers, so all the transition SnapMirrors grind to a halt until you re-input those credentials.

The good news is that it’s perfectly possible to write a batch file, and re-add the credentials using this batch file. You could even set a scheduled task to run this batch file, to make sure the credentials are loaded. One issue scheduling this with a batch file is that we have to use plain text passwords (if anyone has a cunning solution around this, please let me know.)

Here’s an example batch file to show how it’s done (adding 2 host credentials). Save as say Add_7MTT_Credentials.bat and double-click to run.

echo "START"

echo mypassword | transition credentials add -h host1_IP_FQDN -u admin

echo mypassword | transition credentials add -h host2_IP_FQDN -u admin

echo "END"

pause

Nice and simple!

Note: Version of 7MTT was 3.2.0.
