Problems running glance on HP-UX

Hendrawan — Tue, 26 May 2009 06:27:13 +0000

Do you know what's glance?
Glance is a system performance monitoring and diagnostic capabilities software from HP. Glance is more powerful when your running on HP-UX environment, cause they collect all information that require for monitoring the system in a real time. But, there's no 100% perfect software, yesterday I have a little problem when running with glance, but as usually, we solve the problem like a pieces of cake.

here's the summary about the problem

== Fatal Nums Error == C.03.72.00 09/29/03 ==
User: aragon(/dev/pts/tf) Date: Fri May 22 15:58:14

Errno: 0 (Error 0)
Connection to midaemon lost -- check midaemon process and status.mi
== End of Error Msg =============================

Litte magic comes bellow

sh> su -
sh> mwa stop
sh> ps -ef | grep midaemon

sh> kill -9 5005
sh> mwa start

and then try glance again.

FTP Refused connection on HP-UX

Hendrawan — Sat, 09 May 2009 05:27:23 +0000

When we try connected to HPUX server with FTP client with another user except root, sometimes we got a small problem with that.
But don't be afraid, we got some workaround here.

Ok now let's start the trial
1. First we try to connect to HPUX server with FTP from any client, with user "oracle".

bash> ftp rohan
Connected to rohan.
220 rohan FTP server (Revision 3.0 Version wuftpd-2.6.1 Wed Dec 19 08:27:34 GMT2007) ready.
User (rohan:(none)): oracle
331 Password required for oracle.
Password: *****
530 Login incorrect.
Login failed.
ftp> bye
221 Goodbye.

2. Logging all connection
Back to HPUX, now we try to log all connection, including ftp.

sh> inetd -l

Check if the log was run properly

sh> tail -f /var/adm/syslog/syslog.log
Sep  2 08:35:51 rohan ftpd[22988]: FTP server (Revision 3.0 Version wuftpd-2.6.1 Wed Dec 19 08:27:34 GMT 2007) ready.
Sep  2 08:35:54 rohan ftpd[22988]: FTP LOGIN REFUSED (shell not in /etc/shells) FROM 10.14.14.12 [10.14.14.12], oracle

As you can see, inetd logging was run properly. But wait, see end of line of log, yes!! that the answer for that mysterious small problem on ftp connection.

3. Add user shell on listing system shell
Like i said before, in the line of log on syslog file, that's the answer for this problem. Ok. Now we do like syslog said.

sh> grep oracle /etc/passwd
oracle:RHMbMFlgIVmB.:109:106::/home/oracle:/bin/bash

mmm, oracle used "bash" on default shell, on HPUX "bash" was not default install, ok next, we add that "bash" shell at default listing shell on HPUX.

sh> echo '/bin/bash' >> /etc/shells

4. Gotcha!!
All set. now we try to ftp again from client to HPUX server, with oracle user.

dos> ftp rohan
Connected to rohan.
220 rohan FTP server (Revision 3.0 Version wuftpd-2.6.1 Wed Dec 19 08:27:34 GMT2007) ready.
User (rohan:(none)): oracle
331 Password required for oracle.
Password:*****
230 User oracle logged in.
ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
.cshrc
.exrc
.login
.profile
.sh_history
stage
.bash_history
226 Transfer complete.
ftp: 68 bytes received in 0.00Seconds 68000.00Kbytes/sec.
ftp> by
221-You have transferred 0 bytes in 0 files.
221-Total traffic for this session was 367 bytes in 1 transfers.
221-Thank you for using the FTP service on rohan.
221 Goodbye.

it's work, easy like a pie, don't forget to check syslog.

sh> tail -f /var/adm/syslog/syslog.log
Sep  2 08:43:23 rohan ftpd[23227]: Data port : 20
Sep  2 08:43:23 rohan ftpd[23227]: FTP server (Revision 3.0 Version wuftpd-2.6.1 Wed Dec 19 08:27:34 GMT 2007) ready.
Sep  2 08:43:27 rohan ftpd[23227]: FTP LOGIN FROM 10.10.14.172 [10.10.14.172], oracle
Sep  2 08:43:31 rohan ftpd[23227]: FTP session closed

Rename Volume Group on HP-UX (quick & dirty)

Hendrawan — Sun, 22 Mar 2009 10:37:32 +0000

Can you explain how to rename a volume group (VG)?, How to rename your Volume Group on HP-UX ? and many more question about how to rename the volume group. here I show you the magic of how to rename your Volume Group.

bash> bdf|grep /rdbms/oradata/a
/dev/vg07/lvol1    5144576 3515198 1527542   70% /rdbms/oradata/a

We will rename VG07 to VG20, backup your data first.

Backup VG config First

bash> vgcfgbackup /dev/vg07
Volume Group configuration for /dev/vg07 has been saved in /etc/lvmconf/vg07.conf

Ok, now deactivate the first volume group

bash> vgchange -a n /dev/vg07
Volume group "/dev/vg07" has been successfully changed.

Export Vg07 dengan nama 'vg20.map'

bash> vgexport -v -s -m /tmp/vg20.map /dev/vg07
Beginning the export process on Volume Group "/dev/vg07".
/dev/dsk/c5t0d0
Volume group "/dev/vg07" has been successfully removed.

Create New Volume group (VG20)

bash> mkdir /dev/vg20
bash> mknod /dev/vg20/group c 64 0x1a0000

Import VG nya

bash> vgimport -v -s -m /tmp/vg20.map /dev/vg20
Beginning the import process on Volume Group "/dev/20".
Logical volume "/dev/vg20/lvol1" has been successfully created
with lv number 1.
Volume group "/dev/vg20" has been successfully created.

Last but not least, Enable the VG

bash> vgchange -a y /dev/vg20
Activated volume group
Volume group "/dev/vg20" has been successfully changed.
