OSError: [Errno 21] Is a directory: '/etc/ipsec.d/cacerts/save'

A manual creation of a folder named save that was created under /etc/ipsec.d/cacerts/ interfered with the checks required for security certificates renewal.

Workaround:

1. Log in to the VPLEX Management Server using the service account credentials:

login as: service
Using keyboard-interactive authentication.
Password:
service@vplex01:~>

2. Go to the /etc/ipsec.d/cacerts/ path and check for a folder called save:

service@vplex01:~> cd /etc/ipsec.d/cacerts/
service@vplex01:/etc/ipsec.d/cacerts> ll save

3. Delete the file with the name save:

service@vplex01:/etc/ipsec.d/cacerts> rm -rf save

4. Delete the old certificates before running the security configure-certificate command as follows:

service@vplex01:~> rm /etc/ipsec.d/*/*pem* 

5. Go to the VPLEXCLI and run the security configure-certificates command again and check it ran successfully:

VPlexcli:/> security configure-certificates

6. If the command still fails, contact Dell Customer Support and refer to this article.
