Plan to set semaphore values in netbackup servers

Team,

We have taken a reference from Symantec web link about setting on the semaphore values in Solaris 10 servers.

Could you please verify once and kindly suggest its backout plan on  solaris 10 servers.

https://support.symantec.com/en_US/article.TECH62633.html  >>>>>>>>>>>>>>>>>>>>>>> web link

For Sun servers, it has sol 10 does not require to set SEMMNS entries

First create a NetBackup project (id = 1000) and "tune" it.

/usr/sbin/projadd -U root -c "NetBackup resource project" -p 1000 NetBackup

To modify, the value:

/usr/sbin/projmod -a -K 'project.max-sem-nsems=(privileged,300,deny)' NetBackup

/usr/sbin/projmod -a -K 'project.max-sem-ops=(privileged,32,deny)' NetBackup

/usr/sbin/projmod -a -K 'project.max-sem-ids=(privileged,1024,deny)' NetBackup

Check the project created :

projects -l NetBackup
NetBackup
      projid : 1000
      comment: "NetBackup resource project"
      users  : root

      attribs :‘project.max-sem-nsems=(privileged,300,deny)' NetBackup’

                                       'project.max-sem-ops=(privileged,32,deny)' NetBackup’

                                       'project.max-sem-ids=(privileged,1024,deny)' NetBackup’

Now check whether vnetd and bpcd have the entries in SMF 

svcs -a | egrep 'bpcd|vnetd'

online 08:30:10 svc:/network/bpcd/tcp:default
online 08:30:10 svc:/network/vnetd/tcp:default

Next, run the below command to import the changes into SMF.

#  inetconv -f
100235/1 -> /var/svc/manifest/network/rpc/100235_1-rpc_ticotsord.xml
Importing 100235_1-rpc_ticotsord.xml ...Done
bpcd -> /var/svc/manifest/network/bpcd-tcp.xml
Importing bpcd-tcp.xml ...Done
vnetd -> /var/svc/manifest/network/vnetd-tcp.xml
Importing vnetd-tcp.xml ...Done 

4. Now arrange for SMF to launch the NetBackup daemon processes in the NetBackup project just created. This should be performed for both the vnetd and bpcd daemons.

Find the NetBackup vnetd service name:

# /usr/sbin/svccfg list | grep vnetd
network/vnetd/tcp  

Check the current setting for project, 'default' is the default:

# svccfg -s network/vnetd/tcp listprop | grep project
inetd_start/project            astring  default

Change the service to run in the NetBackup project:

# svccfg -s network/vnetd/tcp setprop inetd_start/project=NetBackup

Verify the change is applied:

# svccfg -s network/vnetd/tcp listprop | grep project
inetd_start/project            astring  NetBackup

Follow the same steps for the bpcd daemon:

# svccfg list | grep bpcd
network/bpcd/tcp
# svccfg -s network/bpcd/tcp listprop | grep project
inetd_start/project            astring  default
# svccfg -s network/bpcd/tcp setprop inetd_start/project=NetBackup
# svccfg -s network/bpcd/tcp listprop | grep project
inetd_start/project            astring  NetBackup

Check the effects of the tuning on a running process with the prctl command.

# /usr/openv/netbackup/bin/bpps | grep bptm

#/bin/prctl -n project.max-sem-memory pid

5. Check the effects of the tuning on a running process with the prctl command. In this example, the bpps command on the media server shows the process id of bptm to be 3428 and the output of the prctl command shows the shared memory setting to be 8GB:

# /usr/openv/netbackup/bin/bpps | grep bptm
  root  3428     1   0 12:05:39 ?           0:00 bptm
# /bin/prctl -n project.max-shm-memory 3428
process: 3428: bptm
NAME    PRIVILEGE       VALUE    FLAG   ACTION       RECIPIENT
project.max-sem-memory
      privileged      8.00GB      -   deny                 -
      system          16.0EB    max   deny                 -

Confirm the current NetBackup project settings:

# projects -l NetBackup
NetBackup
      projid : 1000
      comment: "NetBackup resource project"
      users  : root
      groups : (none)
      attribs:‘project.max-sem-nsems=(privileged,300,deny)’

               ‘project.max-sem-ops=(privileged,32,deny)’

              ‘project.max-sem-ids=(privileged,1024,deny)’
              
Confirm the change and that the project contains just one tunable attribute.

# projects -l NetBackup | grep max-sem
