| hi all,
situation: hp rx2xxx server (2xitanium cpus)
os: hp-ux 11.23
when running
vgcreate /dev/vg03 /dev/dsk/c3t2d0
i get: Increased the number of physical extents per physical volume to 35003.
and a never-ending running process of vgcreate
it does not matter if i use sam or try to create this volgroup by hand
any ideas ?
/dev/dsk/c3t2d0 is a 140GB scsi-320
thanks in advance
cheers
joerg

| my 2 cents.
Check for latest LVM cumulative patch.
Run diskinfo (check man for more options).
Additionally, run:
echo 2400?20X | adb /dev/dsk/c3t2d0
(if the output is:
455xxxxx 45xxxxxx 0 0
0 0 0 0
0 0 0 0
0 0 0 0
you should be k. Else I would log a call with hp)
This was just brainstorming assuming everything else was done right!

| So the pvcreate went OK? Did you use any special or non-default
options with pvcreate and vgcreate?
And yes, my advice for all things LVM is to do it 100% by the command
line.

| thanks so far,
after searching for LVM within HP's suppert center i installed
the following patches that are listet within the serach results:
s700_800 11.23 VxVM 3.5~IA.004 Command Patch 01
s700_800 11.23 LVM chooses metadata in incorrect PV
s700_800 11.23 MC/ServiceGuard A.11.15.00
s700_800 11.X OV DP5.10 patch - SSEA packet
s700_800 11.X OV DP5.10 patch - DOC packet
i tried to create this vg by hand (as read in the docs):
pvcreate /dev/rdsk/c3t2d0
mkdir /dev/vg04
mknod /dev/vg04/group c 64 0x040000
vgcreate /dev/vg04 /dev/dsk/c3t2d0
thats what i did after installing all the patches listed above and
vgcreate still hangs..
killing this vgcreate process doesnt work also.
i also tried to pick up the idea of running
echo 2400?20X | adb /dev/dsk/c3t2d0
which results in:
adb: warning: /dev/dsk/c3t2d0: Unknown file type.
adb: warning: File '/dev/dsk/c3t2d0' is not an object file.
0x2400:
adb: warning: Unrecognized format character - 'X'.
any ideas ?
thanks in advance !!
cheers

Your problem could be the size of your physical extents !
If you keep the default, it must be 4Mo.
You can use vgcreate -s 8 or vgcreate -s 16 to increase the size of your
physical extents to 8 Mo or 16 Mo. It is usually used with great
capacity disk.

| Joerg,
This sounds like a known issue with HP-UX 11.23 and LVM with large volumes.
Basically the theory goes that the VGRA (volume group reserved area, an
area of data defining the layout of the VG and replicated across all
physical volumes in the VG) must fit within a single LVM logical (and
physical) extent. As you have not specified an extent size, LVM will
default to 4MB. If the VGRA needed to satify the size of disk you are
dealing with exeeds this size, you will experience a hang with vgcreate
with 11.23.
Prior to 11.23, the vgcreate command would simply have failed with an
error suggesting insufficient space. This issue with 11.23 has
allegedly been reported to HP labs and is being fixed. Meanwhile, the
vgcreate command will hang with no info given as to the reason.
For a solution: increase the size of the extent space. LVM already
granted a "Max PE per PV" of 35003 at 4MB (which would tie in with your
140GB disk size). So if the above theory is true, try the following
commands:
# pvcreate /dev/rdsk/c3t2d0
# mkdir /dev/vg04
# mknod /dev/vg04/group c 64 0x040000
# vgcreate -s 8 -e 17501 /dev/vg04 /dev/dsk/c3t2d0
This will set up your VG with an extend size of 8MB, which should be
enough to cope with the size of your disk(s). If not, try 16MB with the
max PE's reduced accordingly (vgcreate -s 16 -e 8750 /dev/vg04
/dev/dsk/c3t2d0).
Bear in mind a lot of the current LVM code comes from the early HP-UX
version 10 days when 9GB & 18GB disks didn't exist and 4GB disks were a
luxury...
Hope this helps.

As was suggested further up the thread, try adding -s 8 into your
vgcreate command.
e.g. vgcreate -s 8 /dev/vg17 /dev/dsk/c19t9d0 ...

| use vgcreate with the -e option. this will work.
vgcreate -e XXXXX /dev/vgX /dev/dsk/c1t1d0.

| use the -e, -s options for vgcreate.
vgcreate -e 4350 -s 32 /dev/vg03 /dev/dsk/c3t2d0. this will work. make sure
you have the the number of extents correctly so you don't waste any.
