25 Jul 13 Replacing a bad vxvm boot disk. HP-UX 11.23 PA-RISC
So you lose a boot disk on a vxvm booted system. You hot replace the disk, but now you need to make sure the software mirror is good.
Lets say for example its rootdisk02
If the disk stayed alive and did not power down you can run vxbrk_rootmirror and cleanly replace the disk.
What do do if the disk powered down?
/opt/VRTS/bin/vxdiskunsetup -C rootdisk02
vxrecover -g rootdg -sb
You more than likely end up with a disk named like this that is totally useless:
rootdg.26724.31359
vxdg destroy rootdg.26724.31359 (on rootdisk02)
Remove the incomplete mirror copy
/etc/vx/bin/vxbrk_rootmir -v rootdisk02
And mirror it back ,
/opt/VRTS/bin/vxrootmir -v -g rootdg rootdisk02

02 Oct 12 How to not blow up a vxvm boot HP-UX system when breaking the mirror
This is an improvement to fixing the problems if you do blow things up. Click here to see.
Here is the thing. VXvM is messed up on HP-UX. The mirror break command is broken on 11.23 and 11.31.
That being said depending on how you use it, you can have a mess to clean up or not.
Scenario:
[shmuel01]/root # vxdisk list
DEVICE TYPE DISK GROUP STATUS
c2t0d0 auto:hpdisk rootdisk02 rootdg online failing
c2t1d0 auto:hpdisk rootdisk01 rootdg online failing
…
Note the disks are supposedly failing. Easy fix, though I can’t say how long this will last.
[shmuel01]/root # vxedit -g rootdg set failing=off rootdisk01
[shmuel01]/root # vxedit -g rootdg set failing=off rootdisk02
Now we look at them.
[shmuel01]/root # vxdisk list
DEVICE TYPE DISK GROUP STATUS
c2t0d0 auto:hpdisk rootdisk02 rootdg online
c2t1d0 auto:hpdisk rootdisk01 rootdg online
Now they are fixed.
Now to the heart of the matter. Lets say you want to break c2t0d0 out of the mirror and say make a drd image. The man page and HP support says you can use this form.
/etc/vx/bin/vxbrk_rootmir -g rootdg -vb c2t0d0
If you use that form on many HP-UX systems the mirror break will fail and you will have a mess to clean up. If you want to prove your skills go ahead and use that form and click the link above to find the fix.
If you would rather look smart and say cruise the Internet, do this form.
/etc/vx/bin//vxbrk_rootmir -g rootdg -vb rootdisk02
You get the following UGLY results.
[shmuel01]/root # /etc/vx/bin//vxbrk_rootmir -g rootdg -vb rootdisk02

However the only thing that actually goes wrong is removing the disk rootdisk02 from the roodg.
Easily fixed with a single command.

11 Jul 12 Online JFS filesystem expansion without umount
This requires add in software from Veritas/Symmantec that can be expensive on HP-UX.
Lets say we want to extend /var which is lvol8.
It was originally 600 LE and we extended it as follows.
lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2
The 800 refers to LE logical extents. I prefer to use this rather than MB because it corresponds to the values displayed by most lvm utilities. -L <value in megabytes> can be used. I assume you can do the math here.
[system099]/root # lvdisplay /dev/vg00/lvol8
— Logical volumes —
LV Name /dev/vg00/lvol8
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 1
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 12800
Current LE 800
Allocated PE 1600
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation non-strict
IO Timeout (Seconds) default
It was originally 600 LE and we extended it as follows.
lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2
fsadm -F vxfs -b 12800M /var
This command will use online JFS to extend the filesystem. The alternative is extendfs. But that requires a umount. Or perhaps xvumount -o force. Your choice, I don’t recommend it, but did test it the other day in the sandbox.
Now if you want to be cute and use all your space, try this.
SIZE=$(lvdisplay /dev/vg00/lvol8 | awk ‘/LV Size/ {print $NF}’);
ESIZE=”${SIZE}M”
fsadm -F vxfs -b $ESIZE /var
You can get more cute and do it with a single command line but I’m not going to do that. I have not broken any systems this week and am trying to avoid that.

21 Jun 12 Taking apart a blown up vxvm boot system
Scenario:
vxvm boot system shut down decommissioned. It was left off for over a year. Hardware is needed. System is brought up.
Now you have rootdisk2 part of the boot disk group and to do anything useful you need to clean it up.
Get data:
vxprint -ht -g rootdg
I thought to write this only after I was done. So I don’t have a before state picture.
vxdg -g rootdg rmdisk rootdisk02
Getting rid of the sub disks (BE CAREFUL)

21 Jun 12 When swinstall will not install: What to check
I’ve just been through another frustrating battle with swinstall and wanted a complete what to check list in the event that it won’t install software:
- Check that system ip address (ifconfig lan#) is the same as defined in /etc/hosts . If this is not consistent, swinstall will not work and the error message is far from meaningful.
- Check that /etc/nsswitch.conf exists. After a clean install it does not exist and needs to be put in place.
- Check that nfs is working correctly for nfs based install. Bounce nfs.client,nfs.server,nfs.core in that order to stop reverse order to start ex /sbin/init.d/nfs.core <start/stop>
- Use showmount -e <remotehost> to insure connectivity to remote depots.
- swlist -l depot -s <remote host depot>
- swreg -d depot $PWD on remote host after cd to depot. Remember in many scenarios remote depots in tape format will not install.
- /usr/sbin/swagentd -r (Should be taken after any of the above corrective steps).

20 Jun 12 Force umount when a file system won’t umount
Lets say we have a file system mounted as /stuck
umount /stuck
Mount Point busy.
fuser -cu /stuck
# shows no open processes on the filesystem. umount won’t work.
umount has no documented -f (force) paramter
vxumount is the tool of choice here.
vxumount -o force /stuck
/stuck is no longer stuck
vxmount is not always in the PATH. It is something worth searching for and is available on most HP-UX systems.
Only works on vxfs file systems, not HFS or NFS.
07 Jun 12 awk trick of the day(month?) parsing bdf output. awk with if else logic
Ever try and do system reporting based on bdf?
Annoying as all heck that sometimes the output is two line and sometimes one? I was forced to solve that problem today.
if [ “$OS” = “HP-UX” ]
then
dcmd=bdf
fi
arraypointer=0
exec $dcmd | egrep -v “%used|/dev/deviceFileSystem” | awk ‘{lvn=$1;v=$2;if (v==””) {getline;cap=$1;ucap=$2;acap=$3;puse=$4;mp=$5;printf “%s %s %s %s %s %s\n”, lvn,cap,ucap,acap,puse,mp} else {printf “%s %s %s %s %s %s\n”, $1,$2,$3,$4,$5,$6} }’ | while read -r p1 p2 p3 p4 p5 p6
do
#### calculations
done
Typical bdf output:
/dev/vg00/lvol9 4096000 3140019 896285 78% /var/adm/crash
/dev/vg_stgb1/lvol1
1572765696 1382813225 178080447 89% /steven05stgb
More when the script is done
