14.3 Adding LVM disk space
A 5620 SAM system occasionally requires additional disk space to accommodate
system or network growth. Before you add disk capacity to a component that uses
the RHEL LVM function, you must ensure that the disk throughput and latency
values of the new volume are within 10% of the values for the current volume. If the
values differ by more than 10%, contact the 5620 SAM Platform Team through your
Alcatel-Lucent account representative.
Perform Procedure 14-4 to check the disk performance of a component.
Procedure 14-4 To test the disk throughput and latency on a
5620 SAM component
1 Perform one of the following:
a Perform the following steps to shut down a 5620 SAM main server.
i Log in to the main server station as the samadmin user.
ii Navigate to the /opt/5620sam/server/nms/bin directory.
iii Enter the following:
bash$ ./nmsserver.bash force_stop ↵
iv Enter the following to display the server status:
bash$ ./nmsserver.bash appserver_status ↵
The command returns a status message.
v The main server is stopped when the command returns the following
status message:
Application Server is stopped
If the command returns a different message, repeat step iv. Do not
proceed to the next step until the server is stopped.
b Perform the following steps to shut down a 5620 SAM auxiliary server.
i Log in to the auxiliary server station as the samadmin user.
ii Navigate to the /opt/5620sam/auxserver/nms/bin directory.
iii Enter the following:
bash$ ./auxnmsserver.bash force_stop ↵
Caution — Performing this procedure requires stopping one or more
5620 SAM components. Ensure that you perform this procedure only
during a scheduled maintenance period.
