Support is only provided for the assignment of iSCSI IP addresses by DHCP, which is specified via the
following two attributes and corresponding values:
TcpipViaDHCP “Enabled”
IscsiViaDHCP “Enabled”
Due to this restriction, Virtual I/O pools don’t have a provision for assigning IP addresses, subnet, or gateway
values for iSCSI.

In the above FC/FCoE attributes related to boot-from-SAN, the attributes assigned by OME, for automatic
identity assignment, are the VirtWWN, VirtWWPN, and VirtFIPMacAddr attributes. A value for the
VirtWWN attribute is obtained by using the FCoE Node Name Identities definition specified for the Virtual I/O
pool, a value for the VirtWWPN attribute is obtained using the FCoE Port Name Identities definition specified
for the Virtual I/O pool, and a value for the VirtFIPMacAddr attribute is obtained by using the “Ethernet
Identities” definition given for the Virtual I/O pool.
