Changing iSCSI boot parameters on the network adapter after the first boot does not update the iSCSI and networking configuration on the ESXi host.
If you change the iSCSI boot parameters on the network adapter after the first ESXi boot from iSCSI, the host will boot in a stateless mode.
The firmware uses the updated boot configuration and is able to connect to the iSCSI target and load the ESXi image. However, when loaded, the system does not pick up the new parameters, but continues to use persistent networking and iSCSI parameters from the previous boot. As a result, the host cannot connect to the target and boots in the stateless mode.
- Use the vSphere Web Client to connect to the ESXi host.
- Re-configure the iSCSI and networking on the host to match the iBFT parameters.
- Perform a rescan.
