unable to read physical volume Hp-ux EVA

[bitou]

Hello,

i have a problem in my storage EVA.

i created a LUN on my EVA.

it seems that the physical volume has a problem but until now i didn't know why? and how can we resolve? .

the physical volume is a LUN created on 5000 EVA and presented to rp 4400 server. from ioscan command i can see two paths to this Vdisk.(it is normal situation)

but when i try the commands i received the message"unable to read the physical volume"

my steps is as follows: -pvcreate /dev/disk/disk14 -mkdir /dev/vg01 -mknod /dev/vg01/group c 64 0x020000 -vgcreate /dev/vg01 /dev/disk/disk14 ----> error:unable to read the physical volume

any help please?

Check the LUN on the disk array and make sure you have it set appropriately for your OS version (it should probably be set to HP-UX mode and NOT Windows  on the EVA).
