[Vengatesh]

I got below error excuting vgcreate command

Command : vgcreate -s 256 /dev/vg01 /dev/disk/disk81

vgextend /dev/vg01 /dev/disk/disk82 /dev/disk/disk83

The "Error" did not appear on the screen, right?

Please post

I cannot see any disk81/82/83 at all.


If thes are not there, you cannot use them.




BTW, consider to use the agile device files when configuring VGs, your display is showing the legacy deviec files only.

[Vengatesh]

sorry i am using below command

vgcreate -s 256 /dev/vg01 /dev/dsk/c4t0d0

vgextend /dev/vg01 /dev/dsk/c4t0d1
vgextend /dev/vg01 /dev/dsk/c4t0d2

vgextend /dev/vg01 /dev/dsk/c6t0d6
vgextend /dev/vg01 /dev/dsk/c6t0d7

[Torsten.]

I assume this is working now.


Look at this:

/dev/rdisk/disk20 /dev/rdsk/c4t0d1
/dev/rdsk/c6t0d1


c4t0d1 and c6t0d1 are alternates. You extend them both to vg01.


But better use disk20!!!

Consider to use "vgdsf" to convert or start over and use the new device files.

[Vengatesh]

No still problem ,

my hdd size 500gb , so please kindly provide the procedue document dcoument.

thanks

[Torsten.]

You shuld NOT do


vgcreate /dev/vg01 /dev/dsk/c4t0d0

but better do


vgcreate /dev/vg01 /dev/disk19


and so on.

[Vengatesh]

# vgcreate /dev/vg01 /dev/dsk/c4t0d1
Increased the number of physical extents per physical volume to 17919.
vgcreate: Volume group "/dev/vg01" could not be created:
The path does not specify a valid physical volume.

[Torsten.]

According to your previous post it is already part of vg01 - what did you change yesterday?

[Vengatesh]

i have remove the VG and try to recreate the VG

[Torsten.]

So please post

# ioscan -fnCdisk

and

# ioscan -m dsf

and

# strings /etc/lvmtab

[Vengatesh]

# ioscan -fnCdisk

[Torsten.]

Make sure the LUNs are presented in r/w and hpux mode. Consider to use /dev/disk/disk20 when creating the VG.

[shanmuhanandam]

Hi,
if the persistent device files are available, then why are you going for the LDSF? (Multipathing will be enabled if you are using Persistent DSF). It is better to use Persistent DSF's.

And as per you earlier post, the disk c4t0d1 was part of vg01, and you might be exported/removed the vg01. so you need to do the pvcreate for the disk c4t0d1. so please try the following..

#pvcreate /dev/rdisk/disk20
#vgcreate vg01 /dev/disk/disk20

Thanks,
Shan.

[Ismail Azad]

Hi....

Ok then,

ioscan -funNC disk
These are your "available" disks vengatesh {pretty sure that's a spelling mistake}
And use it with these options

Now do strings /etc/lvmtab
These are the disks used by LVM, you cannot vgcreate and specify a disk{PV} as an argument for a disk that is already part of a vg.

pvcreate -f /dev/rdisk/disk20

> This creates a PV on your raw disk.

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
Seems, like you need to do these steps. Device files are required for identifying the "entities" in LVM.

vgcreate -s 256 /dev/vg01 /dev/disk/disk20

This creates a VG vg01 with one disk disk20 with an extent size of 256 MB

As your using 11.31, let the /dev/disk/diskx be your friend and avoid using /dev/dsk/cxtxdx. Now there are commands to completely transition and migrate from that mode of DSFs.

Welcome to ITRC..... Hope some of this has helped you and don't forget to assign points...
