Mirroring a big lvol on more disks

[Mauro Cimino_2]

Having a 8 Gb lvolume on more disks than one it's possible mirror it on other disks ?

I don't undestand how can I use the command lvextend if I have to use more disks.

lvextend -m 1 /dev/vg01/lvol1 /dev/dsk/c1t1d0 /dev/dsk/c1t2d0 /dev/dsk/c1t3d0

Share and Enjoy! Ian

Hi,

You can add the disks after the lvextend command.

# lvextend -m 1 /dev/vg??/lvol? /dev/dsk/c?t?d? /dev/dsk/c?t?d?

Yes. If you have enough disks with enough space in the same volume group then you can simply do; lvextend -m 1 /dev/vgXX/lvolYY and it will mirror over multiple disks.

and if my lvol is split on more disks that are not fully engaged, are the mirror disks filled at the same manner?
