Reason: password lifetime has passed + HPUX

Error:

#password

Password cannot be changed. Reason: password lifetime has passed.



Solution:


1. check the lockout condition for that user by command #/usr/lbin/getprpw

lockout=1001000

The position, left to right represents:

1 past password lifetime

2 past last login time (inactive account)

3 past absolute account lifetime

4 exceeded unsuccessful login attempts

5 password required and a null password

6 admin lock

7 password is a *


2. To reset the password age to zero

# /usr/lbin/modprpw -v {username}


3. Then unlock the user account

# /usr/lbin/modprpw -k {username}

or #/usr/lbin/modprpw -m alock=no -k username


4. If the problem persist then check the /tcb/files... for a particular user. May be it has been corrupted.

so manually edit the password there.

Run 'scsimgr replace_wwid' command + HPUX

Run 'scsimgr replace_wwid' command + HPUX

Error:

class : lunpath, instance 269

Evpd inquiry page 83h/80h failed or the current page 83h/80h data do not match the previous known page 83h/80h data on LUN id 0x0 probed beneath the target path (class = tgtpath, instance = 12) The lun path is (class = lunpath, instance 269).Run 'scsimgr replace_wwid' command to validate the change

Solution:

If we see above error in #dmesg then

1. #scsimgr -f replace_wwid -C lunpath -I 269

Binding of LUN path with new LUN validated successfully

2. Scan the disk again so new id which was assigned to the disk, will get reflacted.

    #ioscan –fnNC disk    

     -N displays output using the agile view instead of legacy view

3. #insf -e -C disk

4. #dmesg

root file system is 100% + HPUX

My root file system is 100%

1. First thing to do is look for core files:

  # find / -name core

2. Then check for mistakes in the /dev directory (usually caused by someone       mistyping a device name:

  /dev/rmt/Omn instead of /dev/rmt/0mn, for example)

3.1) # find / -xdev -size +10000 -exec ll {} \; > /tmp/hugefiles

    It will give you a list of all big files ( >10000) under root.

3.2) 10 largest directories in the root filesystem:

    $ du -kx / | sort -rn -k1 | head -n 10

3.3) 10 largest files in the root filesystem:

     $ find / -type f -xdev -print | xargs -e ll | sort -rn -k5 | head -n 10

3.4)  Recently modified files in the root filesystem:

     $ find / -type f -xdev -mtime -1 -print | xargs ll | sort -rn -k5

4.  If we run any LVM commands then it will change the VG configuration files     under /etc/lvmconf

5.  check your crontab if any script running and writing somewhere under /

7.  Run cleanup -F

8. There is nothing special about this file. It’s a sequential text file.
    /root/dead.letter if it is there we can trim it.

vxfs fsadm error + HPUX

If you get this error while extending FS

Error:   vxfs fsadm: attempt to resize /dev/vg01/opt_oracle failed with errno 28

Ans: Here issue is that the mount point is 100% full. 

fsadm does not work well if there is no space left on the device. We have to figure out some way to free up some space temporarily, by moving some files to another mount point or removing some files.

Thanks...

fsadm: You don't have a license to run this program + HPUX

Error:

fsadm: You don't have a license to run this program

1. We encountered this error while extending the FS. If we dont have onlineJFS product installed on the server then we will not be able to extend/reduce FS online.

2. Check  if an Online JFS product is installed:

# swlist -l product | grep -i online

3. If online JFS is installed then:

3.1. /usr/sbin> /usr/sbin/vxlicense –p     

vrts:vxlicense: INFO: Feature name: HP_OnlineJFS [50]

vrts:vxlicense: INFO: Number of licenses: 1 (non-floating)

vrts:vxlicense: INFO: Expiration date: Sun Jun 24 10:00:00 2007 (455.8 days ago)

vrts:vxlicense: INFO: Release Level: 22

vrts:vxlicense: INFO: Machine Class: All

vrts:vxlicense: INFO: Site ID: 0

3.2.  #/usr/sbin/vxlicrep -e; /sbin/fs/vxfs/vxenablef -a

   The first command will query the fsadm license & the second cmd wil activate the license.

3.3.  If the license is expired, as soon as you reboot this system the JFSOnline function will be disabled.

3.4.  Need to request a new codeword and re-install onlinejfs.  Send an email to HP on  'hplicense.na@hp.com'.  They will give you a codeword for OnlineJFS (if you are entitled to it).

Easy commands + HPUX

Easy commands:

1) Commands to restart sendmail service:

/sbin/init.d/sendmail stop;sleep 10;/sbin/init.d/sendmail start

2) Command to stop sshd:

#ps –ef |grep –i ssh

# kiil –HUP

HUP - Hang UP - it tells daemon to go and reread its configuration file as certain changes have been made which we have to incorporate now. The process doesn't actually stop, it just likes stated, rereads its config file. This is true only for daemon processes. For normal application it hangs-up the terminal.

3) Creates a new user account:

useradd [ -c comment ] [ -d dir ] [ -e expire ] [ -g group ] [ -G group1,group2 ... ] [ -m [ -k skel_dir ] ] [ -u uid ] [ -s shell ] [ -r role1,role2 ... ] login

4) 10 largest files under /var directory:

$ find /var -type f -xdev -print | xargs -e ls -lrt | sort -rn -k5 | head -n 10

5) Top 10 Ten processes consuming high Memory:

echo " SZ PID RUSER COMMAND";UNIX95= ps -ef -o 'sz pid ruser args' |sort -nr|head -10

6) To check the top 10 Ten process consuming high CPU

echo " %CPU PID RUSER COMMAND" ;UNIX95= ps -ef -o 'pcpu pid ruser args'|sort -nr|head -10

How to Identify Luns on EMC- Clariion Storage + HPUX

How to Identify Luns on EMC- Clariion Storage (DGC     :CX4-240WDR5) in HP11iV3

1.       Device name/Lun id’s are : 404/402/400 and 114

Convert it into Hexadecimal:  194/192/190 and 72

2.       Try to grep the hex number :

testserver:/dev/disk# /usr/local/bin/inq.HPUXIA64 -clariion -no_dots |egrep '194|192|190|72'

/dev/rdisk/disk115    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    41943040:  16: 2a0:ASSIGNED

/dev/rdisk/disk172    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    37748736:  1a:  33:ASSIGNED

/dev/rdisk/disk234    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    37748736:  27:  72:ASSIGNED

/dev/rdisk/disk246    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    37748736:  28: 190:ASSIGNED

/dev/rdisk/disk247    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    37748736:  29: 192:ASSIGNED

/dev/rdisk/disk249    :DGC     :CX4-240WDR5     :HP03  :Ch2 CONT   :    37748736:  2a: 194:ASSIGNED

3.       We can verify the same in /dev/disk directory:

testserver:/dev/disk# ls -lt |more

total 0

brw-r-----   1 bin        sys          1 0x000034 May  2 14:34 disk249

brw-r-----   1 bin        sys          1 0x000033 May  2 14:34 disk247

brw-r-----   1 bin        sys          1 0x000032 May  2 14:34 disk246

brw-r-----   1 bin        sys          1 0x000031 May  2 14:34 disk234

4.       Also the disks in scsimgr output; the ‘SCSI services internal state should be UNOPEN’

#scsimgr -v get_info all_lun |more

or 

#scsimgr get_info -D /dev/rdisk/disk249 |grep -i "SCSI services internal state"
