DataDirect Networks SFA™ OS 2.2.1.3 Release Notes Revision A1 | 15

After a SHUTDOWN CONTROLLER or SHUTDOWN SUBSYSTEM, which ends with an

IPMI Power Off, the canister fan may restart even though the canister is in the

shutdown or standby state.

Resolution: This condition is benign except that it makes it confusing whether the

canister is shutdown or not. If all five canister LEDs are off, then it did indeed shut

down (trust the LEDs).

[FPGA-78]

•

Occasionally an extra enclosure shows up in SHOW ENCLOSURE immediately after

powering up the system.

Resolution: Shut the system down, power-cycle, and start it up again.

[SEP-23]

• With SFA7700 BMC/FPGA 21.97/2.3-0.49 the reported battery charge will not rise to

100%. Maximum charge levels may be as low as 89%. This should not affect the ability

of the battery pack to hold up the canister during a power failure. The issue will be

fixed in the next BMC/FPGA release.

5.6 Red Hat 6.2

This section applies to the SFA12K-40, SFA12K-20, SFA10K-X, and SFA10K-M.

• Updating the kernel and multipath packages to the latest version is recommended. As

of this release, minimum DDN qualified versions include:

o the kernel version - 2.6.32-279.2.1.el6.x86_64

o the multipath version - 0.4.9-56.el6_3.1.x86_64.

• The kernel modules that come with OFED 1.5.4 will cause I/O threads to hang when

the data path between the controller and switch is lost. A workaround for this issue is

to use the Red Hat supplied InfiniBand solution. For a switched InfiniBand

environment:

o Install the in-box OFED drivers that come with RHEL 6 Update 2

o Update the multipath-tools package to a minimal version of 0.4.9-56.el_3.1

o Do not use user-friendly names in multipath.conf

o Configure RHEL 6 Update 2 to a minimal kernel version of 2.6.32-279.2.1.el6

• These packages are required for InfiniBand support on Red Hat. (Use the command

yum groupinstall infiniband to install all IB packages):

o ibutils-1.5.7-6.el6.x86_64

o infiniband-diags-1.5.12-3.el6.x86_64

o opensm-libs-3.3.13-1.el6.x86_64

o opensm-3.3.13-1.el6.x86_64

o libmlx4-1.0.2-5.el6.x86_64

o srptools-0.0.4-15.el6.x86_64

• To start IB lun discovery, issue these commands:

1. modprobe ib_umad
