Hi,

try this command to check lvm information is written to disk:

echo '0x2008?2X' | adb /dev/dsk/c11t0d0

also try pvcreate with -f argument.

Kenan.

Shalom,

You may have forgotten a step here.

Did you do a mknod command for the new volume group?

Hi Sanjay....

Still Having same problem....

[Torsten.]

Looks like this array supports only 11.23 and 11.31:

Check this again.

If there are different "presentation" modes available, check if you set them to hp-ux mode.

Hi Punithan,

Are you adding the disk from fujitsu storage for the first time to this server having B11.11 OS. Is another similar server having same OS having these disks and working proprely there. If all this is ok then there is no need to think that your Server supports fujitsu storage or not.

try first diskinfo on any one disk and DD also.
Do pvcreate -f devicepath
mkdir vgname
mknod /dev/vgname/group c 64 0x------
vgcreate -s 16 -l 255 -p 255 -e 5119 /dev/vgname /dev/dsk/cxtxdx
vgextend /dev/vgname all other disks

Thanks

So long as you skip the mknod step you can't create a volume group.

That simple.

Was your original post accurate?

Hi Steven

May be miss mknod command in my document.
But i did the mknod command. Still having same problem.

And this is first time we adding Fujitsu Storage to HPUX Server.
But we have done for other server before this. such as Linux, Sun, Windows.

Any idea to solve my problem.....
