hidden:Starting and Stopping HPSS

Activate/deactivate HPSS on either hpsscr04 or hpsscr05

1.Activate HPSS 
run: /hat/core_manual/bin/hpss_activate_node.ksh
This script:
- activates hpss volume groups
- mounts hpss file systems
- sets IPs of the productive HPSS core
- starts hpss and DB2
- copies /hat/core_manual/etc/root_active_crontab over /var/spool/cron/root
2.Deactivate HPSS active core 
run: /hat/core_manual/bin/hpss_deactivate_node.ksh
This script:
- stops HPSS and DB2
- umounts all HPSS file systems
- deactivates all HPSS volume groups
- takes away all HPSS productive IPs
- deletes /var/spool/cron/root

Please note:
- if you solely want to stop HPSS and DB2 but have access to HPSS file systems
please see below how only stop hpss
- if you want to set a cronjob on the active core, write it in 
/hat/core_manual/etc/root_active_crontab
to be activeted at the next run of 
/hat/core_manual/bin/hpss_activate_node.ksh

Stop HPSS on the active core without deactivating it

1.Stop all HPSS processes and DB2
/opt/hpss/bin/rc.hpss stop

2.Alternatively you can do it in more steps for a better overview 
 
2.1.Start the command line on the core server and stop all server 
/opt/hpss/bin/hpssadm.pl -U hpssssm -a /var/hpss/etc/hpss.unix.keytab
hpssadm> server shutdown -all
hpssadm> server list -all  
hpssadm> quit
2.2.Stop startup daemon
/opt/hpss/bin/rc.hpss -d stop
2.3.Stop system manager
/opt/hpss/bin/rc.hpss -m stop
3.Stop the database
2.1./opt/hpss/bin/rc.hpss stop

Start HPSS and the database

as user root on the core server

/opt/hpss/bin/rc.hpss start
/opt/hpss/bin/hpssadm.pl -U hpssssm -a /var/hpss/etc/hpss.unix.keytab
hpssadm>server start -all
hpssadm>server list -all  
hpssadm> quit

Alternatively you can stop HPSS servers using HPSS GUI

In this case stopping is done in two steps. 
First in the GUI all hpss servers are to be stopped and then the database is to be stopped.

1. open the HPSS GUI on the active Core-Server
/opt/hpss/bin/hpssgui.pl &
2. click on Operations --> Shutdown --> All Non-SSM Servers
3. then Operations --> Shutdown --> System Manager

Then stop the database:

/opt/hpss/bin/rc.hpss stop
