      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;ESX host enumerates devices based on the PCI order in which they are discovered. Particularly with UCS-Service profiles you can strictly govern the order and naming convention, this is not possible on other hardware platforms.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;You can get around by modifying the esx.conf file.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Did you clone the service profile or carve out seperate ones for each server ? If its the latter , check the device order - remember that vHBA &amp;amp; vNIC are both carved out from the CNA cards, so order of both NIC and HBA are important.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;yes he profile was cloned from a template. but was unbinded and rebinded back to the template. I dont understand why the other hosts shows a different number since both of them are cloned from the same template&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
