Booting from iSCSI LUN on VMware
After installing the boot image onto the remote LUN, you may need to change the
iSCSI configuration. If the
One Time Disable
option was not used, then the
Boot
to iSCSI Target
setting must be changed from
Disabled
to
Enabled
. To change
this setting, reboot to CCM or UEFI HII. When the host is rebooted, the vSphere
host boots from the iSCSI LUN through the software iSCSI initiator pathway.
Configuring VLANs for iSCSI Boot
iSCSI traffic on the network may be isolated in a Layer 2 VLAN to segregate it
from general traffic. When this is the case, make the iSCSI interface on the
adapter a member of that VLAN.
