you don't need SMC for ECC. Aliases got pulled from symmask login table, if you run "symmask -sid list logins -dir all -p all" you will see all the aliases that have been defined.  In order to define this you either do it manually via command "symmask -sid -wwn 10000000032 rename OracleDB1/h0" or if your hosts have solutions enabler installed then you can run "symmask discover hba -rename" and it will use host's name to populate the entry in the login table.
Greetings,  We have been a Symmetrix and ECC shop for a while and we've finally installed SMC for managing our Symmetrix boxes. We were told SMC is required for ECC 6.1UB5 and above, that's the main reason it's here, but we've decided that we might as well get some use from it.  We've got it installed, symmetrix arrays discovered, licenses installed and user security set up. However, I've noticed that SMC discovered a handfull of Initiator Aliases, but not all of them. I'd like to get these set up as it makes masking a whole lot easier to have a friendly name. So I have two questions:  1. Where did SMC initially pull these aliases from and why not all of them? 2. How can I populate the rest of the HBA WWNs with Aliases, aside from doing one at a time?  Thanks for your time.
