Add Disk to Current Mirrored Volume

[Zean Wilmot]

Hi

I am after some advise on how to add a new disk to current mirrored group < VG03 > .

This at present is mirrored across c5t8d0 & c7t8d0.

Can anyone advise me on how to create the new disk and add to current mirror

Thanks Zean

pvcreate /dev/rdsk/cXtXdX
vgextend vgXX /dev/dsk/cXtXdX

U can mirror logical volumes now ! Note that u have only a single disk and if u mirror it on the same disk ... it does'nt give u redendancy during a drive failure !.

May be we can help you if you come back with disk sizes !
