Hello,

Check your disks are properly available to HP-UX. Run the following commads,

# ioscan -fnC disk
# dd if= of=/dev/null bs=1024k

Disks is ok, i have only disk and is available. I check the fibre channell statistics and it's ok.

Thank you.

can you paste what you have on display for these commands.

ioscan -fnC disk
vgdisplay -v
diskinfo -v ( dont forget to use rdsk)
pvdisplay -v

Jesus,
Method to create VG is as follows, see if you are missing something or else check your hardware and it's connections.

# ioscan -fnC disk
Select the disk on which you would like to create VG. Say for e.g. c4t4d4.

# strings /etc/lvmtab | grep c4t4d4

Check whether it already exists, if not then proceed. (In SAN environment you need to check it on all server in the network)

# pvcreate -f /dev/rdsk/c4t4d4
This creates PV on that disk

# mkdir /dev/vgxx
# mknod /dev/vgxx/group c 64 0x0y0000
Here value of y should be unique

# vgcreate vgxx /dev/dsk/c4t4d4

That's all.
