cannot create volume group

Paul Wright — Mon, 23 Jun 2003 13:25:00 GMT

On saturday we had a consultant in to hook up our HP9000 box to our new CX600.
She did a pvcreate and
mkdir /dev/vgtemp
mknod /dev/vgtemp/group c 64 0x030000
HOWEVER....................
when she tried to do a vgcreate, we got the following error message:
Increased the number of physical extents per physical volume to 42495.
vgcreate: Volume group "/dev/vgtemp" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.

I'm hoping someone out there has seen this before and can shed some light on it.
Thanks
Paul

Youre trying to create a voulme group with a large device. To do so you need to increase the PE size from the def 4MB to 8 or probably 16MB. (vgcreate -s)

I had the same issue with my scsi to ide array.

It's seen as a single 1TB disk.

I wanted to use the same PE size as on our XP256 which was 4.

But since the disk size was too large i had to increase the PE to 16 then it worked fine.

Cheers

George

Do a "diskinfo" on the disk and see how big it is. Then do the appropriate arithmetic as described in other responses.

How big did you make the LUNs on the CX600?

I think this is a duplicate posting from the same author:
