HP XC System Software Installation Guide Version 4.0

Restart only the master candidate hosts? [y/n] n
Do you really want to restart LIMs on all hosts? [y/n] y
Restarting the LIM daemon is required because the licensing of LSF with SLURM occurs
when the LIM daemon is started. This means that the LIM daemon will be licensed only for
processors that are actually available at that time, which might be fewer than the total number
of processors available after all nodes have been imaged and are up and running.
7. Update the LSF batch system with the latest resource information reported by SLURM:
# badmin reconfig

7.2 Enabling SSH for the InfiniBand Interconnect
This task applies only if the system is configured with an InfiniBand interconnect. Omit this task
for all other interconnect types.
Follow this procedure 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. Begin this procedure as the root user on the head node.
2. Set up SSH on the switch to enable HP XC applications to work without a password:
# cat /root/.ssh/id_dsa.pub | ssh root@IR0N00 cat '>>' /.ssh/authorized_keys
You might be prompted to enter the InfiniBand switch root password. The factory default
password is br6000. If you set a unique password for the switch, enter that password
instead.
7.3 Creating a Lock LUN Device File
Perform this task only if you configured improved availability of services and are using
Serviceguard as the availability tool. Omit 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 as the first disk:
# sfdisk -R /dev/sdb1
7.4 Starting Availability Tools
Perform this task only if you configured improved availability of services regardless of the
availability tool you are using. Omit 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
Info: Status check for nodes supporting availability:
Info: Node 'n7' up and running
Info: Node 'n8' up and running
Info: Serviceguard-managed services are: 'nat lvs nagios dbserver'
Info: NAT HA servers are: 'n7 n8'
Info: confirming the list of services to transfer to availability...
Info: 'serviceguard' not running anywhere.
