Yes. Call Red Hat and EMC Support.

You have NEVER followed up, said thanks, or even acknowledged that others help you. You're obviously in a corporate environment, and from your past posts, are using RHEL. RHEL with EMC SAN is a well-supported environment. Call them, that's what they're there for. And after you being here for NINE YEARS, you still don't post details. There's no way of knowing what LUN's you've presented to the server, so there's no way to know if what you're seeing is right or not.

Really?? The support for both RHEL *AND* the EMC SAN? EMC SAN devices are VERY expensive...support typically doesn't expire, since the only way any serious company (like one that can AFFORD and EMC device) would have one, is to keep it supported and up to date. The only way it could happen would be for a company to get RID of an EMC unit, in favor of something else.

And you ignore what has been said to you SEVERAL TIMES:

There's no way of knowing what LUN's you've presented to the server, so there's no way to know if what you're seeing is right or not.

Read that again...pay particular attention to the part about the DETAILS. You tell us NOTHING about the HBA's, what you THINK you should see, what the SAN team tells you they're presenting, or even what version/distro of Linux. And also...I don't believe that you have an RHEL and EMC SAN environment that doesn't have support. If you want help here, post details, and try to show you're putting some effort into things. Saying "thanks", spelling out your words, and just plain following up is a good plan too...especially since you've been doing this for NINE YEARS NOW.
