vgcreate problem with EVA

ITeam — Tue, 09 Aug 2005 06:06:10 GMT

Hi,
Getting error: /dev/vg01/group not a character device
- when I try to vgcreate vg01 /dev/dsk/c14t0d0
, where c14t0d0 is a 300GB space allocated on an EVA box. I've done the pvcreate okay and dont have trouble with vgcreate on non-EVA "disks".

Suggestions/comments about my stupidity most welcome!

(PS: Yes, I have checked in ioscan that the path to the EVA exists on 255.255.0.0 !).

Many thanks.

What's the output of:
diskinfo /dev/rdsk/c14t0d0 ?

And did you create /dev/vg01/group?

Hi,
I doubt you didn't create group file.
use mknod.
If you are not familier with commands use SAM to create new VG/LV/FS.

Regds
TT

mkdir /dev/vgnew
mknod /dev/vgnew/group c 64 0x0y0000
(y system wide unique VGid)
pvcreate /dev/rdsk/cxtydz
vgcreate /dev/vgnew /dev/dsk/cxtydz
lvcreate ......
newfs....
mount ....

Refer to man pages

Ho-hum! Yep - it was the lack of a mknod that was the start of it all!

Have now created one and am getting further (I just now need to play around with the extents sizing so it can use all the available size!).

Many thanks for the amazingly fast responses!

just to save other people's valuable time, I'll close this thread off now.
Thanks again everyone!
