symapi_db.bin on my unix sever is out of sync

Which symcli version are you using ?? I suspect you have an old version (5.5 or older) since with 6.x EMC introduced daemons and usually they do a discover every night and even more then once a day.

Here you can see messages from symapi log of an host running S.E. 6.4.x. You can find symapi logs in /var/symapi/log directory ..

As you may notice, symcli issue a discover at different times, all day long...

You also ask about ECC .. ECC do trigger an automated discovery of the symmetrix every night. It's a policy you can configure in ECC (it's a DCP, Data collection policy). Your host however needs to have a Symmetrix agent if you want ECC to trigger the discover. Maybe you already know.. but worth mentioning that every host have its own symapi_db.bin file and that there isn't an ECC policy that triggers the update of any available symapi_db.bin file.
Are you running Symmetrix agent on the host that's showing the strange behaviour ??
