Solution

To resolve this issue,

1. Add the following code to the end of the

/lib/udev/rules.d/50-udev-

default.rules

file:

# InfiniBand

KERNEL=="umad*", NAME="infiniband/%k"

KERNEL=="issm*", NAME="infiniband/%k"

KERNEL=="uverbs*", NAME="infiniband/%k"

KERNEL=="ucm*", NAME="infiniband/%k"

KERNEL=="uat", NAME="infiniband/%k"

KERNEL=="ucma", NAME="infiniband/%k"

KERNEL=="rdma_cm", NAME="infiniband/%k"

2. Run the following command to restart

rdma:

# /etc/init.d/rdma restart

3. Wait for a few seconds after

rdma has restarted, and then run the following commands to

verify that the changes have solved the issue:

# srp_daemon -oac

# opensm

OpenSM will now start as expected, as will SRPTools.

LINUX CLEANUP AFTER LUN REMOVAL

Linux does not automatically clean up after ION Accelerator LUN removals. For RHEL and OL, the

required steps for LUN removal are described here:

https://access.redhat.com/site/documentation/en-

US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/removing_devices.html

These instructions also work for SLES.

For all distros, before running

multipath –f, run the following command:

dmsetup message mpathXYZ 0 "fail_if_no_path"

where mpathXYZ is the name of the device.
