vgcreate error

[amir syafiq]

Im using RP3410 with HPUX 11.11.

Command that I used to create VG:-

#vgdisplay –v vg01
vgdisplay: Volume group "/dev/vg01" does not exist in the "/etc/lvmtab" file.

ALL look ok

Then I used pvcreate with option f (force)

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#mkdir /dev/vg01

vgcreate: Volume group "/dev/vg01" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.

# vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0
Increased the number of physical extents per physical volume to 8940.
vgcreate: Volume group "/dev/vg01" could not be created:
The path does not specify a valid physical volume.

That the error, try remove the device file using command rmsf , delete the vg01 folder, rename lvmtab file to lvmtab.bak, vgscan –v and etc. the error still same.

I try dd and diskinfo command and look ok to me:-

Hi

Please repeat pvcreate -f /dev/rdsk/c3t2d0 again
mkdir /dev/vg01
ll /dev/*/group
if you found group file for vg02 remove that
mknod /dev/vg01/group c 64 0x010000
vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0

Hi,

Where is group file for vg01?

After creating the /dev/vg01 directory create group file before create the vg

#mknod /dev/vg01/group c 64 0x010000

[Jeeshan]

hi amir

>>Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (71525).
Using only 65535 PEs from this physical volume.

here is your problem. Because of your max pe parameter is set to low, it can't be expecting more than its setting value.

try to create another vg and create the file systems.

[amir syafiq]

now creating new volume group no problem. but after create the VG:-

# vgcreate -s 16 /dev/vg01 /dev/dsk/c3t2d0
Increased the number of physical extents per physical volume to 17881.
Volume group "/dev/vg01" has been successfully created.
VGRA appears corrupted


when i try to deactivate or reboot the VG01 can't start.

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#vgcreate â s 16 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created
VGRA corrupted

# vgchange -a n vg01
Volume group "vg01" has been successfully changed.

# vgchange -a y vg01
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.

[Sharma Sanjeev]

Hi Amir

Activate your VG with no quoram

vgchange -a y -q n /dev/vgname....

than check vgdisplay -v vgname and look for the disks in this VG.

Sanjeev

Hi,

Better remove the VG and recreate it to get out of the mess.

Just export the VG to remove the configuration entirely from the system

#vgexport -v vgname

Now create freshly.

[amir syafiq]

i remove all vg01 config, device file c3t2d0,rename /etc/lvmtab file and create vg again.

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#mkdir /dev/vg01

#mknod /dev/vg01 /dev/dsk/c3t2d0

#vgcreate â s 16 â p 126 â e 65535 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created

# vgchange -a n vg01

# vgchange -a y vg01

# vgchange -a y -q n vg01

attach log

[Duncan Edmonstone]

at this stage I would be thinking:

a) patches - do you have all the latest LVM patches installed?
b) bad disk? do you have another disk you can try the operation on?

Hi Amir

Just looked at you previous reply

#vgcreate â  s 16 â  p 126 â  e 65535 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created
VGRA corrupted


Here it created VG but error is there
VGRA Corrupted

Regards
Sanjeev

[Jeeshan]

did you check the latest patch?

[amir syafiq]

that the issues, before this i try to create vg but unsuccesful. Then download new LVM cumulative patch and install to the system with no error, after taht try to create the VG. succesfull but come with error VGRA corrupted.

same error if I create new LV, after reboot or vgchange system unable to activate the VG and mount the LV.

New patch:- PHKL_35970 - s700_800 11.11 LVM Cumulative Patch

Hi Amir

U can give One try for below

vgexport vg01
delete group file
dd if=/dev/null of=/dev/dsk/c3t2d0
pvcreate -f /dev/rdsk/c3t2d0
mkdir /dev/vg01
mknod /dev/group/vg01 c 64 0x20000
vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0

[Torsten.]

Do you have any external devices connected to this servers built-in SCSI port?

Please post a full "ioscan -fn".

[Duncan Edmonstone]

I always worry when people indicate they installed just a single patch... Did you installl all the patch dependencies that go with the patch you mentioned?

HTH

Duncan

[amir syafiq]

Thanks all for the guide.
I Already do that step 3 times, at last same thing happen VGRA corrupted. Is they a way to fix VGRA?

[Torsten.]

Please keep this in mind:

On this server the built-in SCSI port and the upper internal disk slot is the same bus.

It is recommended to have devices only on 1 side - internal or external.

Otherwise you will have very unpredictable behavior, I have seen very similar symptoms on a server with an "open" scsi cable connected to the external port - no devices, no termination - just an open bus.

Please check this.

[amir syafiq]

Hi Torsten
I will find the scsi device and connect to built-in scsi port, after that i'll post the ioscan -fn output.

Hi Duncan
Yes, I download with all dependency and install with default option. Patch installed with no error.

Amir

[amir syafiq]

Hi Torsten,

I check the hardware several times, no external scsi device connected to the build-in scsi port. The only thing wire came from the server is utp cable and power cable

case close, problem just because of scsi terminator which
normally automatic terminate by server itself, but in this case
don't know why the automatic terminator didn't work properly.
solution just put hardware terminator and problem solve. suspect
maybe firmware to old.
