Re: Moving date from one EVA to another
- review the currently setting of this VG
# vgdisplay -v vgxx
- adjust values if needed
(man vgmodify)
- create a new vdisk on the new EVA (probably same size preferred)
- adjust zoning and presentation
- run "ioscan" and "insf" on the new device
- create a physical volume on the new vdisk
(man pvcreate)
- extend the VG
(man vgextend)
- extend the logical volume
(man lvextend)
# lvextend -m 1 /dev/vgxx/lvol1 /dev/dsk/...
- reduce the mirror copy from the old disk
# lvreduce -m 0 /dev/vgxx/lvol1 /dev/dsk/...
- once all lvols are "moved", reduce the old vdisk from the VG
Hope this helps!
Regards
Torsten.

Re: Moving date from one EVA to another
I have the following configuration:
Volume Group - vgSLT
The Logcal Volumes:
/dev/vgSLT/sapmntSLT
/dev/vgSLT/usrsapSLT
/dev/vgSLT/oracleSLT
/dev/vgSLT/oracle
VG resides on phisycal disk /dev/dsk/c13t0d0
Now I need to present new vdisk to secure path?
For example let it be /dev/dsk/c14t0d0
Then I need to perform
vgextend /dev/vgSLT /dev/dsk/c14t0d0
lvextend -m 1 /dev/vgSLT/sapmntSLT /dev/dsk/c14t0d0
lvextend -m 1 /dev/vgSLT/usrsapSLT /dev/dsk/c14t0d0
lvextend -m 1 /dev/vgSLT/oracleSLT /dev/dsk/c14t0d0
lvextend -m 1 /dev/vgSLT/oracle /dev/dsk/c14t0d0
then
lvreduce -m 0 -k /dev/vgSLT/usrsapSLT /dev/dsk/c13t0d0/
etc..
and
vgreduce /dev/vgSLT /dev/dsk/c13t0d0
Am I on the right way?

Re: Moving date from one EVA to another
Yes.
Also be aware of the other steps I mentioned (checking limits/pvcreate etc.).
Hope this helps!

Torsten.
