Business copy import.

[wayne_104]

Hi I need some help please.

The storage admin guy has made a snapshot of the data.

I now wish to import it into my volume group which i have made.

but when i do a pvcreate i get.

pvcreate -f /dev/rdisk/disk41
pvcreate: Couldn't open physical volume "/dev/rdisk/disk41":
No such device or address


LSSF gives me
lssf /dev/disk/disk41
esdisk section 0 at address 64000/0xfa00/0x13 /dev/disk/disk41

VGVHGID
vgchgid /dev/rdisk/disk41
vgchgid: Couldn't open physical volume "/dev/rdisk/disk41":
No such device or address


DISK INFO

diskinfo /dev/rdisk/disk41
diskinfo: can't open /dev/rdisk/disk41: No such device or address

Why you need a business copy of a LUN when you delete the data with pvcreate???

Please tell.


Make sure the array allows write support to that LUN.

Well as far as i see it I will have to do a vgchgid.

I mkdir /dev/vgxx
then mknodd

then pvcreate /dev/disk/disk41

vgchgid /dev/rdisk/disk41

then vgimport /dev/vgxx /dev/rdisk/disk41.

A "pvcreate" will give you an EMPTY disk, it will delete the data on the disk/LUN.

Do a vgchid followed by an vgimport.

[wayne_104]

been assured it has write permission to the lun

[wayne_104]

ok will start over and do vgchgid first

Hi ,

Are you going to import the disk to the same system?

It says about your rdisk!!!

could you please do
#insf -eC disk
then check if the device file name is there in rdisk folder
check ioscan and see if claimed.

Then just do vgchgid
ensure all the disks in the VG must have a given as arguments to the command.

dont do a pvcreate, you will not able to do a vgimport anymore!!

Ok this is result of vgchgid

vgchgid /dev/rdisk/disk41
vgchgid: Couldn't open physical volume "/dev/rdisk/disk41":
No such device or address

Did you find the disk in ioscan?

Let's start with

# ioscan -fn

# ioscan -m dsf

[wayne_104]

ioscan -m dsf /dev/disk/disk41
Persistent DSF Legacy DSF(s)
