iSCSI Extensions for RDMA
This chapter describes the procedure for configuring iSCSI Extensions for RDMA
(iSER) for RHEL and SLES. As you prepare to configure iSER, consider the
following:
iSER is supported only in INBOX OFED for following operating systems:
RHEL 7.1, RHEL 7.2
SLES12 SP1
Out-of-box OFED does not support iSER target configuration and no ib_isert
module is available for latest out-of-box OFED versions.
After logging into the targets or while running I/O traffic, unloading the Linux
RoCE qedr driver may crash the system.
While running I/O, performing interface down/up tests or performing cable
pull-tests can cause driver or iSER module errors that may crash the
system. If this happens, reboot the system.
Configuring iSER for RHEL
To configure iSER for RHEL:
1.
Configure in-box OFED, as described
“Configuring In-box OFED for RHEL”
. Out-of-box OFEDs are not supported for iSER because the
ib_isert module is not available in the out-of-box OFED-3.18/3.81-1 GA
versions. The inbox ib_isert module does not work with any out-of-box
OFED versions.
2.
Unload any existing FastLinQ drivers, as described in
Drivers in a RoCE Environment” on page 11
3.
Install the latest FastLinQ driver and libqedr packages, as described in
“Installing Linux Drivers for RoCE in an In-box OFED Environment” on
page 14
