I have HBA adapter in ESX 3.5 , I got this information from one of the ESX server :

Emulex LightPulse FC SCSI elx_7.4.0.40
Emulex LP1050 2Gb PCI-X Fibre Channel Adapter on PCI bus 05 device 69 irq 185
BoardNum: 1
SerialNum: MX30519096
Firmware Version: 1.90A4 (M2F1.90A4)
Hdw: 1001206d
VendorId: 0xf0a510df

My server is ProLiant DL585 G1 , I have tried to find firmware update for this HBA in Emulex or HP website but I couldn't , is anyone know how to find this firmware for ESX , and if I found it , is the installation from esx or it's hardware base
