Storage adapters 8Gb Fibre channel host adapter is missing after ESX server joined ESX Pool

Hi

I am new to VMware. Recently, i have installed ESX 4.1.0 update 1 on my new blade server. After the new ESX 4.1 machine joined to the existing esx pool, i cant able to view the storage adapters information such as WWN numbers from Vsphere client. The storage adapters information can see it on server profile and Virtual connect switch. Kindly advise. Thx.
