[Discuss] Fibre Channel and CentOS 5 issues

[jay at lentecs.com (Jason Normand)]

We are working on setting up some new hardware for our db servers, but I am
having trouble getting the Fibre Channel LUN recognized by CentOS 5.7.  We
are running on an IBM x3550 with dual Brocade HBAs, and have them connected
to an IBM DS3524 with dual controllers.  Each controller is direct attached
to one HBA.  I am able to get Cent to see the LUN if i power cycle the
controllers, however it will not see it after a system reboot.  The HBAs
are recognized after reboot but rescanning the scsi bus does not help.
 Only a power cycle on the controllers or a reset of the LUN will get Cent
to recognize it.

Now I have little experience with Fibre Channel and was looking for some
pointers in the right direction.  Does this sound like a hardware issue or
a Cent config/driver issue?

Thanks
