Ankush, The driver version is obsolete. The lastest version recommended by EMC for most of Emulex HBA (not CNAs) drivers is 2.74.014. You can check your Emulex HBA model for the exact version.
You must upgrade the driver and firmware to a supported level first. i remember 2.10 was from w2k3 time before the VNX was released. This may be your issue.
To check the drivers for your HBA, Follow the belkow link::
let us know if it got fixed.

As per Mohammed Salem, just keep in mind if the HBA is an OEM product that is supported for EMC Use, be sure to obtain the latest driver from the OEM provider rather than the manufacturer as this will be important if other non-EMC arrays are in the loop.
