Increase lvol size in HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX on May 7, 2010
Let’s assume that you want to increase 1Gb of the /dev/MyVG /lvol1 device (mounted as /filesystem):
# bdf /filesystem
Filesystem kbytes used avail %used Mounted on
/dev/ MyVG /lvol1
573440000 533892407 37080557 94% /filesystem
The actual size is 573440000 Kb (573 Gb) and you will increase it to 574440000 Kb (574 Gb).
- Check if there is available space in the Volume Group:
# vgdisplay MyVG
--- Volume groups ---
VG Name /dev/MyVG
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 1
Open LV 1
Max PV 100
Cur PV 17
Act PV 17
Max PE per PV 15000
VGDA 34
PE Size (Mbytes) 16
Total PE 36907
Alloc PE 35000
Free PE 1907
Total PVG 1
Total Spare PVs 0
Total Spare PVs in use 0
Note the “Free PE” and “PE Size (Mbytes)”. It say that you has 30512 Mb (30Gb) available in MyVG (Free PE * PE Size).
- Increase the lvol:
# lvextend -L 574440 /dev/MyVG/lvol1 * the syntax is: lvexten -L <new size in Mb> <lvol path>
- Now, increase the filesystem:
# fsadm -b 574440m /filesystem * the syntax is: fsadm –b <new size in Mb> <mount point>
Changing the HP-UX hostname
Posted by Lincoln Zuljewic Silva in HP-UX on May 7, 2010
To change the hostname in HP-UX:
- Edit the file "/etc/rc.config.d/netconf"
# /etc/rc.config.d/netconf
- Look for the line that starts with HOSTNAME and change the hostname, example:
HOSTNAME="mylittleserver"
- Now, apply the change:
# /sbin/init.d/hostname start
Rename a Super Dome Partition
Posted by Lincoln Zuljewic Silva in HP-UX on April 23, 2010
To rename a Super Dome Partition (for example change the name that is showed in the MP console menu), do the following:
Login into any host of this SD and run:
parmodify -p <partition number> -P <partition name>
Example:
parmodify -p 2 -P WEBSERVER01
Glance shortcuts
Posted by Lincoln Zuljewic Silva in HP-UX on February 4, 2010
To use the buttons at the bottom of the glance, you should do an "export TERM=dtterm".
After that, you will be able to use:
F1 for ProcList
F2 for CPU Rpt
F3 for Mem Rpt
F4 for Disk Rpt
F5 for NextKeys
F6 for SlctProc
F7 for Help
F8 for Exit
Control agent problem (OVO)
Posted by Lincoln Zuljewic Silva in HP-UX on January 8, 2010
Sometimes the OVO agent stops communicating with the OVO Server.
Control agent on nodeHOST isn't accessible. (OpC40-405) Network communication problem: Could not obtain endpoint information from node ncadg_ip_udp:10.0.0.10[]. (OpC40-399)
To reestablish the communication, you should restart it:
To stop, use the command:
# /opt/OV/bin/OpC/opcagt -stop
Check if it is stopped:
# /opt/OV/bin/OpC/opcagt -status
ITO Managed Node status :
-------------------------
Control Agent /opt/OV/bin/OpC/opcctla (3818) is running
Message Agent /opt/OV/bin/OpC/opcmsga (3819) is running
Subagent 1:
Action Agent /opt/OV/bin/OpC/opcacta (3820) is running
Logfile Encapsulator /opt/OV/bin/OpC/opcle (3821) is running
Monitor Agent /opt/OV/bin/OpC/opcmona (3822) is running
Message Interceptor /opt/OV/bin/OpC/opcmsgi (3823) is running
Attention: the "Control Agent" may not stop, you can kill it with a "kill -9 PID"
To start, use the command:
# /opt/OV/bin/OpC/opcagt -start
Check powerpath links in HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX on December 22, 2009
To check if the powerpath links are up in HP-UX, you can use the following command:
# powermt display dev=all
When Glance stop working
Posted by Lincoln Zuljewic Silva in HP-UX on December 6, 2009
Sometimes glance (performance monitor for HP-UX) can crash (before crash, it will return 0% of CPU, Disk and networking) working with the following error:
GlancePlus fatal error.
== Fatal Nums Error == C.04.50.57 02/10/07 ==
User: root/6pts/6(/dev/pts/6) Date: Sun Dec 6 15:52:12
File: /crm/numsVob/hp/11.0/nums.C Line: 485 Product id: Glance
System: server B.11.11 9000/800
Errno: 0 (Error 0)
Connection to midaemon lost -- check midaemon process and status.mi == End of Error Msg
=============================
To solve it, you should:
Stop MWA:
# mwa stop
Remove all files (including the hidden ones) from /var/opt/perf/datafiles:
# rm -rf /var/opt/perf/datafiles/* rm -rf /var/opt/perf/datafiles/.*
Check if midaemon and ttd are stopped:
# mwa status
If midaemon and ttd didn’t stop, force stops them with the command kill (the PID was returned by the command ‘mwa status’).
Now, start MWA again:
# mwa start

# /usr/lbin/modprpw -m alock=YES USER
Merge many depots
Posted by Lincoln Zuljewic Silva in HP-UX on August 25, 2009
When you have many depot files, you can create a single big depot and install it instead of install one by one. Let’s assume that you need install the following depots, and they are all located in the directory /tmp/install/depots:
autoconf-2.64-hppa-11.11.depot bison-2.4.1-hppa-11.11.depot gawk-3.1.7-hppa-11.11.depot sed-4.2.1-hppa-11.11.depot tcltk-8.5.7-hppa-11.11.depot texinfo-4.13-hppa-11.11.depot zip-3.0-hppa-11.11.depot
To create a single depot, run the follow commands:
# cd /tmp/install/ for i in `ls depots/*.depot` ;do swcopy -s /tmp/install/$i \* @/tmp/install/big;done
Now, to install it, you can use:
# swinstall -s /tmp/install/big
HP-UX password maintenance

Follow a few utilities to maintain the user’s passwords:
/usr/lbin/getprpw <username> - display protected password database information
/usr/lbin/modprpw -x <username> – change password
/usr/lbin/modprpw -k <username> – unlock the user

Recovering corrupted lvol on HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX on May 14, 2009
Sometimes you can get the following error while try to access a directory in HP-UX:
# cd /DATA
sh: /DATA: The specified directory is not valid.
This error is caused because the file system is corrupted and you need run fsck on it.
First of all, umount the FS:
# umount /DATA
And them, run the fsck:
# fsck -y -o full /dev/vgLOG/lvol1on clear? (ynq)y
UX:vxfs fsck: WARNING: V-3-20836: file system had I/O error(s) on meta-data.

SSH Memory fault(coredump) in HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX, Linux on April 16, 2009
If you try to access from a HP-UX another machine that has a newer version of SSH running, you may get a “SSH Memory fault(coredump)” message like the following one:
# ssh -v server
