30 Nov 17 No downtme migration of mounted filesystem to new storage type
On LVM 1.0 Volume group, the task is no downtime storage migration. Hitachi to Pure Solid State storage. Mirror/UX required.

28 Nov 17 An xpinfo that works in hpvm guests and on non Hitachi storage
Hitachi shops faced annoyance times two:
1. xpinfo does not work on non-Hitachi storage for example Pure storage
2. xpinfo does not work on hpvm guests depending on how the storage is passed through from the hpvm host
I now present xpinfonew which though raw and unfnished
The output:

24 Jul 15 Single user vg00 reconfiguration for a san boot hp-ux system
San boot system.
HBA has to be replaced.
Then you have to boot single user mode to re-establish all your paths.
Procedure authored by my colleague Mahesh Koduru
Before you start make sure you have a current map file hosted on root filesystem.
“Reboot the server and follow these steps :
Interrupt the boot and boot the system in maintenance mode.
fs0:\EFI\HPUX> hpux
HPUX> boot -lm –lq vmunix This will bring the System into Maintance mod
#vgdisplay vg00 The VG should be in deactivated Mod
#ll /dev/*/group Collect the Group file
#vgexport -p -s -m vg00.map /dev/vg00 Keep the Map file in present directory , ie root
# ll vg00.map
#vgexport -v /dev/vg00
#mkdir -m 755 /dev/vg00
#mknod /dev/vg00/group c 64 0x030000 ##This is an example your major/minor number may vary
#vgimport -s -N -m vg00.map /dev/vg00 ## The -N is B.11.31 only to convert to agile storage
#vgchange -a y vg00
#mount -a Mount only Root filesystems
#setboot Check and correct setboot issues
#lvlnboot -v vg00 Check and correct lvlnboot issues , lvrmboot command can be used if needed
#/usr/sbin/lvlnboot -v
# lvlnboot -r /dev/vg00 Execute for fixing Boot Labels
# lvlnboot -r /dev/vg00/lvol3
# lvlnboot -b /dev/vg00/lvol1
# lvlnboot -s /dev/vg00/lvol2
# lvlnboot -d /dev/vg00/lvol2
# lvlnboot -v
# lvlnboot -R
Note: Comment the swap in fstab and then issue below command.
# shutdown -ry 0

29 Oct 14 Puzzle of the day. Strict logical volume prevents you from extending a filesystem
Thanks to Veerappan Dhandapani of HCL Technologies for bringing me this problem
You have 50 GB free in the volume group.
You try to extend the logical volume and you cant.
Basics:
1) bdf is the tool for measuring filesystem size not logical volume size
2)lvdisplay is the tool for measuring logical volume size.
Steps:
1) Extend the logical volume. That is why the previous two number points are important. In process after extending the logical volume size the lv size and file system size are not equal
2) Extend the file system.

lvextend: Not enough free physical extents available.
The problem here is the allocation policy.
lvchange -C n -s n /dev/vgdata/lv_prod_datastaging
See the man page for details. -C is for contiguous -s is for strict allocation.
We changed both to n(o).
Off camera we extended the logcal volume

vgreduce vgprotter /dev/dsk/c5t2d2

We check the return code to make sure the operation was a success. Repeat for each legacy device.
No downtime though for prodcution systems I recommend working with a change request under your organizations policy.

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
VxVM vxbrk_rootmir INFO V-5-2-4023 14:23: Checking specified disk(s) for presence and type

VxVM vxmake ERROR V-5-1-1173 Volume swvol already exists
VxVM vxbrk_rootmir ERROR V-5-2-4020 Attempting to recreate volume meta-data on rootdisk02/c2t0d0
However the only thing that actually goes wrong is removing the disk rootdisk02 from the roodg.
Easily fixed with a single command.
vxdg -g rootdg rmdisk rootdisk02
vxdisk list shows:

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
