Hi Akashvenkat ,
Here is few things , that might help you :
1. User Administration:
# useradd -u uid -s /usr/bin/ksh -g pri_group -d /home/username -m username
[ Where uid , pri_group , username : are input ]
# passwd username # setting password.
# passwd -f username # to chg pw at next login.
# usermod -G grp1 grp2 username # to add more group for the user ]
# passwd -l username # To lock a user ]
You can do the same activity through sam also.
2. System Maintenance:
1. To shutdown :
(Make sure nobody working and system needs to shutdown , check oracle and other application stopped.)
# ps -ef | egrep '(ora|pmon)' # to check if oracle running.)
Check Application team before shutting down.
To shutdown for any maintenace or other reason:
# shutdown -h -y 0
To Reboot: ( To watch the reboot, make sure you have logged in GSP/console)
# reboot -r -y 0
To boot in single user mode:
Interrupt normal boot process:
at ISL > hpux -is
3. To check System Logs:
/var/adm/syslog/syslog.log
dmesg
/var/opt/resmon/log/event.log
/var/adm/wtmp , utmp , btmp #login logs.
/var/adm/mail.log # mail log
/var/adm/cron/log # cron log
/var/adm/lp/log # LP logs.
/var/adm/sw/swinstall.log # All sw logs can be found here.
/var/adm/crash # crash dumps.
4. System / devices :
# ioscan -fnC disk # to check disks.
# ioscan -fnC tape # to check tape devs.
# ioscan -fnC lan # to check lan devs.
# ioscan -fnC fc # to check fc adptrs.
# ioscan -fnC ext_bus # to check all ext_bus
# /opt/fcms/bin/fcmsutil /dev/fc0 # to check fc details.(assuming fc0 is the fc adapter )
/usr/bin/cstm # cstm . check "man cstm" for details.
EMS:
# /opt/resmin/bin/resls / # To check resources configured
5. System Backup/Restore:
tar
cpio
make_tape_recovery *Important.
( Use man page to see details.)
6. Kernel tuning:
# kmtune -q parameter # to see current value.
# kmtune -s npty=120 # [Ex: to change npty value ]
# ./mk_kernel
# ./kmupdate
# shutdown -r -y 0 # to make it effective]
Check this:
HP-UX Kernel Tuning and Performance Guide:
http://docs.hp.com/en/1219/tuningwp.html7. Software /Patching:
# swlist -l bundle # [ to see installed bundled ]
# swlist -l product # [ to see installed products ]
# swlist -l fileset # [ to check filesets]
# swinstall -s `pwd`/depot # to install software from created depot directory.
# swverify \* # to verify all sw.
# swremove # to remove sw .
8. Performance monitoring:
# glance
# top
# sar -v 5 5 # to check system table .
# sar -u -M 5 5 # to check cpu uti.
# vmstat 5 5 # swap usuage.
# iostat 5 5 # io usage.
# swapinfo -tm # swap usuage status.
Also check this performance monitoring too:
http://www.hpux.ws/system.perf.sh9. System Inventory:
A. Nickel Script:
http://unixguide.net/scripts/nickel108B. cfg2html
http://come.to/cfg2htmlC. HP collection.sh script.
10. Finding CPU Details:
A.
# echo "selclass qualifier cpu;info;wait;infolog" | /usr/sbin/cstm
B. Finidng CPU speed in Mhz, in a single command:
# echo "CPU Speed is= \c" ; echo itick_per_tick/D|adb -k /stand/vmunix /dev/kmem|tail -1|cut -f2 | awk '{printf "%0f MHz\n", $1/10000}'
C. Memory Details:
# echo "selclass qualifier memory ;info;wait;infolog" | /usr/sbin/cstm
# cat /var/adm/syslog/syslog.log | grep -i physical
11. LP Administration:
# lpsched # to start the scheduler.
# lpstop # to stop the scheduler.
# lpadmin -p pr0 ... # to add printer .
# accept pr0 # to accept the pr0
# denable pr0 # to enable pr0
# lpstat -t # to check lp status.
# cancel req_id # to cancel request.
# man lpadmin [# for details . ]
12. for LVM :
A. pvdisplay , vgdisplay , lvdisplay ...
B. To use MirrorDisk/UX to mirror internal disks. Take a look at this link(Mirroring Data Using LVM section):
