6. See “Troubleshoot the Imaging Process” (page 192) if you encounter problems imaging nodes.
Proceed to “Task 12: Perform Postconfiguration Tasks for the InfiniBand Interconnect”.
3.13 Task 12: Perform Postconfiguration Tasks for the InfiniBand
Interconnect
This task applies only if the system is configured with an InfiniBand interconnect. Bypass this task for all
other interconnect types.
Follow this procedure to create a list of nodes for the InfiniBand diagnostic tools and to set up ssh to
enable applications to function without a password, which is necessary for the proper operation of the
ip_prodmode_mon monitoring utility and the sys_check infiniband component.
1. Create a list of all nodes in the HP XC system. The InfiniBand diagnostic tools requires this list of
nodes to function properly:
# shownode all > /usr/voltaire/scripts/HCA400-Checks/node-list
2. Enter the following command to set up ssh on the switch to enable XC applications to work without
a password:
# cat /root/.ssh/id_dsa.pub | ssh IR0N00 cat '>>' /.ssh/authorized_keys
Proceed to “Task 13: Create a Lock LUN Device File”.
3.14 Task 13: Create a Lock LUN Device File
Perform this task only if you configured improved availability of services under Serviceguard. Bypass
this task if you are not using Serviceguard or if you have not configured a lock LUN to achieve quorum.
If you have used a lock LUN to achieve quorum on one or more availability sets, create the device file on
the second node in the appropriate availability sets. In the following example, /dev/sdb1 is the full path
to the disk and partition of the lock LUN on the first disk; run the following command on the second disk,
specifying the same disk and partition number:
# fdisk -R /dev/sdb1
Proceed to “Task 14: Start Availability Tools”.
3.15 Task 14: Start Availability Tools
Perform this task only if you configured improved availability of services regardless of the availability
tool you are using. Bypass this task if you did not configure availability sets.
Run the transfer_to_avail command to shut down all HP XC services and IP aliases that will be
managed by an availability tool:
# transfer_to_avail
