lvcreate and disk

Carme Torca — Wed, 11 Jan 2006 11:46:35 GMT

Hi,

Is it possible to do lvcreate and put the disk you want to assign?
I'am working with 11.11
something like
#lvcreate -n lvdat1 -L 100 /dev/vg02 /dev/dsk/c1t2d0

Thanks a lot of!
Carmen.

Hi

Adding a filesystem on a particular disk

#lvcreate -n lvdat1 vg02
#lvextend -L 100 /dev/vg02/lvdat1 /dev/dsk/c1t2d0

Carmen,

I don't believe this is possible. You would "vgextend" your vg02 to span additional disk devices, can not do so via lvextend command.

Carmen,

learn something new every day, you can in fact lvextend a mirrored copy of a logical volume to a disk device. You just can't do it via the lvcreate command.

Hi Carme,

You can't define a disk path while creating an LVOL. You have to create a blank LV with the following command.

#lvcreate -n lvdat1 vg02

Then you have to extend that lvol to a purticular disk with

#lvextend -L 100 /dev/vg02/lvdat1 /dev/dsk/c1t2d0

Hi,

Andy,

You can assign the LE's to a desired disk while creating as well as while extending mirrors.

While Creating
#lvcreate /dev/vg00
#lvextend -L xxxx /dev/vgxx/lvol? /dev/dsk/cxtydz

While Extending

#lvextend -m 1 /dev/vgxx/lvol? /dev/dsk/cxtydz

HTH,
Devender
