I have installed Vmware EXS 3i server on HP blades.(after i heard its free). But i am facing problem in connecting or detecting LUNs from my NetApp SAN box. After doing multiple rounds of rescan doesn't work.
Did i miss any other prior setting ?
Are these iSCSI LUNs? Are you using the software iSCSI initiator, or do you have an iSCSI HBA? Did you configure the iSCSI software initiator - enable it, add the target IP address of your NetApp box, etc. On the NetApp box, have you configured the LUN to allow a connection from the ESXi machine(s)?
In addition to what Nick said, are you in control of the LUNS/Storage/Connectivity to Netapp? There could be zoning involved that you may need to allow visibility of the ESX servers to the Netapp LUNS also.
Problem was i have not given gateway addres. I have given a gatway address which does not exists, it worked.
