I WAS WRONG ON THAT : Sun Leadville Emulex driver and EMC Clariion is not a good mix

This week I identified an obscur eproblem to be caused by a bug in the Sun Emulex Leadville driver that Sun wont fix in Solaris 10 from what the support told me. This bug occurs on a host with only 1 hba using leadville and powerpath to access volumes on a Clariion array. When the Clariion SP owning the LUNs reboots, volumes get trespassed and when it comes back online, volumes gets trespassed back to the default SP. One of the LUN then becomes innaccessible causing hard hang on all processes accessing it, processes are not killable even with -9

We are rolling back to emulex lpfc driver after I prove this is leadville's fault tomorrow
