Hi Ben, There are a few KB articles on support.emc.com related to the error message. Have you been through all of them to confirm it is not one of the known causes? If this is not resolved by one of the KB articles, we will need to know a little more about the environment. It might be appropriate to open an SR rather than troubleshooting here. Feel free to post about your environment though, something might raise a flag. -     OS -     Virtual or physical -     SAN access to array? -      Symapi client only?
I've installed Solutions Enabler 8.4 on a server and tried "symacl -unique", but it fails with "Unable to obtain unique ID for host". Most other SymCLI commands also fail with the same error, including "symcfg discover", so the server hasn't yet discovered any VMAX's. I've edited config/options to enable SYMAPI_ALTERNATE_ACCESS_ID and I've tried "symacl -unique -passphrase -force" and "symacl -unique -passphrase -file -force", but they also fail with the same message.   Any thoughts about how to make this server generate a unique ID so I can add it to a symacl accgroup? Thank you!
