You first need to create it (man vgcreate), then you can display it.

hi trsten

i created all like
dir,mknod ,vg

but why it is getting

[Bill Hassell]

You must activate the new VG:

vgchange -a y vg01

Please post the commands you used to create the VG.

Hi:

> i created all like dir,mknod ,vg

Instead of showing pseudo commands, it would be nice to see the *actual* commands you issued. Is your minor number unique in your 'mknod'? Do you realize in 11.31 that the 'mkdir' and 'mknod' steps will be done by 'vgcreate' automatically if you choose? What happens if you do that?

Regards!

Standard procedure to create a VG is:

mkdir /dev/vg01

mknod /dev/vg01/group c 64 0xNN0000

vgcreate /dev/vg01 /dev/dsk/c?t?d?

What did you do?

No, since march 2008 the standard is just


# vgcreate /dev/vgname /dev/disk/disk_



Did you do that?

Hi,

can you recreate the VG, and paste the output here. So that it can be easy for the forum to help you.

Thanks,
shan.

Hi,

In hpux v3 you no need to create directory like vg01 under /dev/

No need to create group file also.

Run command like:
pvcreate pvname
vgcreate vgname pvname

Example

#ioscan -m disk >> find disk persistent device file

pvcreate /dev/rdisk/disk25

vgcreate -s 64 vg01 /dev/disk/disk25

lvcreate -L size in MB vgname

newfs -F vxfs -o largefiles
