# /bin/projects -l NetBackup
projects: project "NetBackup" does not exist

First Time Setup

Here are the steps to create a project for NetBackup 6.5 and have the Solaris 10 Service Management Facility (SMF) launch NetBackup daemon processes in that project. This results in the bptm process being launched with the values tuned in the NetBackup project.

Note: Steps 3 & 4 are not appropriate for NetBackup 7.x. See Related Article TECH138168.

1. First create a NetBackup project (id = 1000) and “tune” it. The following example sets the maximum amount of shared memory to 8GB:

(The commands below have had line breaks inserted for readability, but each should be entered on a single command line.)

# /usr/sbin/projadd -U root -c "NetBackup resource project" -p 1000 NetBackup
# /usr/sbin/projmod -a -K 'project.max-msg-ids=(privileged,256,deny)' NetBackup
# /usr/sbin/projmod -a -K 'project.max-sem-ids=(privileged,1024,deny)' NetBackup
# /usr/sbin/projmod -a -K 'project.max-shm-ids=(privileged,1024,deny)' NetBackup
# /usr/sbin/projmod -a -K 'project.max-shm-memory=(privileged,8589934592,deny)' NetBackup

Note: See TECH1724, in the Related Articles, for advice on appropriate sizing for NetBackup shared memory.

2. The project may be checked with the projects command:

# projects -l NetBackup
NetBackup
projid : 1000
comment: "NetBackup resource project"
users : root
groups : (none)
attribs: project.max-msg-ids=(privileged,256,deny)
project.max-sem-ids=(privileged,1024,deny)
project.max-shm-ids=(privileged,1024,deny)
project.max-shm-memory=(privileged,8589934592,deny)

3. 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

If the above output is not displayed, then make these entries in the /etc/inetd.conf,

bpcd stream tcp nowait root /usr/openv/netbackup/bin/bpcd bpcd
vnetd stream tcp nowait root /usr/openv/netbackup/bin/vnetd vnetd

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

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-shm-memory
privileged      8.00GB      -   deny                 -
system          16.0EB    max   deny                 -

Modifying the Tuning

Once first time setup has been performed, it is necessary to use different command options to modify the settings; repeating the first time settings can lead to unpredictable results.

1. Ensure the NetBackup daemons are being launched by SMF in the NetBackup project:

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

2. Confirm the current NetBackup project settings:

3. To modify a project attribute, use the projmod command with the -s switch.

For example, to increase the maximum shared memory setting to 10GB (10737418240) and the shared memory identifiers to 2048, use the commands:

# /usr/sbin/projmod -s -K ‘project.max-shm-memory=(privileged,10737418240,deny)’ NetBackup
# /usr/sbin/projmod -s -K ‘project.max-shm-ids=(privileged,2048,deny)’ NetBackup

4. Confirm the change was successful and that the project contains just one entry for the tunable attribute that you specified:

<span style="font-family: Arial;"># projects -l NetBackup | grep max-shm
project.max-shm-memory=(privileged,10737418240,deny)
project.max-shm-ids=(privileged,2048,deny)</span>
