Hi..

I have a volume group, which has 1 logical volume in it (spread across 2
disk, hdisk18 and hdisk19). It seems as though hdisk18 is on a slower
disk array, and I've added some faster disk to that volume group, by using

extendlv 'VG_NAME' hdisk49


Now, can I remove the slow disk from the volume group by using

reducevg '-d' VG_NAME hdisk18

without destroying data on the logical volume or filesystem mounted on
those disks ?

Thanks
