11.
Build the
initramfs
file by issuing the following command:
#
dracut -f
12. Reboot the server, and then open the HII.
13. In the HII, open System Configuration, select the adapter port, and then
select
Port Level Configuration
.
14. On the Port Level Configuration page, set the
Boot Mode
to
iSCSI (HW)
and set
iSCSI Offload
to
Enabled
.
15. Save the configuration and reboot the server.
The OS can now boot through the offload interface.
Linux Multipath Considerations
iSCSI boot from SAN installations on Linux operating systems are currently
supported only in a single-path configuration. To enable multipath configurations,
perform the installation in a single path, using either an L2 or L4 path. After the
server boots into the installed operating system, perform the required
configurations for enabling multipath I/O (MPIO).
See the appropriate procedure in this section to migrate from L2 to L4 and
configure MPIO for your OS:
Migrating and Configuring MPIO to Offloaded Interface for RHEL 6.9/6.10
Migrating and Configuring MPIO to Offloaded Interface for RHEL 7.2/7.3
Migrating and Configuring MPIO to Offloaded Interface for SLES 11 SP4
Migrating and Configuring MPIO to Offloaded Interface for
SLES 12 SP1/SP2
NOTE
If you are using an HPE Synergy chassis managed by HPE OneView, create
a server profile and set the
Function Type = "Ethernet"
. HPE OneView
creates a virtual MAC. When performing the migration steps, you may need
to reapply the HPE OneView profile with
Function Type = "iSCSI"
and
apply the profile as
"User Defined"
.
