I couldn’t find a lot of documentation on installing CA signed certificates on Dell EMC Unity arrays, so here are the steps:
1. Download and install openssl on your desktop/laptop.
2. Generate a cfg file using a txt editor, save it under c:\temp\unity1 folder as unity1_cfg.txt.
Example cfg file (modify for your environment):
[ req ] distinguished_name = req_distinguished_name encrypt_key = no prompt = no string_mask = nombstr req_extensions = v3_req [ v3_req ] basicConstraints = CA:false keyUsage = nonRepudiation, digitalSignature, keyEncipherment subjectAltName = DNS:unity1.myitblog.local [ req_distinguished_name ] countryName = GB stateOrProvinceName = State localityName = London 0.organizationName = myitblog.co.uk organizationalUnitName = IT commonName = unity1.myitblog.local
