Description of problem:
TA process is not picking 24007 as port while starting up.


Problem:

In unit file of TA process we have been using ta-vol as volume id and also 
 ta-vol-server.transport.socket.listen-port=24007

In our volume file for TA process we only consider volname as "ta" and not as "ta-vol".
That's why it was not able to assign this port number to or ta process as in volume file it will try to find server xlato as ta-vol

volume ta-server  <<<<<<<<< not ta-vol
 46     type protocol/server
 47     option transport.listen-backlog 10
 48     option transport.socket.keepalive-count 9
 49     option transport.socket.keepalive-interval 2
 50     option transport.socket.keepalive-time 20
 51     option transport.tcp-user-timeout 0
 52     option transport.socket.keepalive 1
 53     option auth.addr./mnt/thin-arbiter.allow *
 54     option auth-path /mnt/thin-arbiter
 55     option transport.address-family inet
 56     option transport-type tcp
 57     subvolumes ta-io-stats
 58 end-volume      




Solution:
Just need to change the command which Unit file is going to execute.
