Re: change storage from DAS to SAN
make backup anyway.
after that umount your VA7110 VG and LV
and make
vgchange -a n VGname
vgexport -v -m /tmp/VAVG.map VGname
reconnect your VA storage using switch.
start VA and make
# ioscan
#insf -e
find that all VA7110 disk is present?
#vgimport -v
-m /tmp/VAVG.map /dev/dsk/cXtXdX .....
where cXtXdX is you new disks device file.
vgchange -a y VGname

Re: change storage from DAS to SAN
Note down the disk names used in the volume group(s) that are on the VA7110 before you vgexport.
vgdisplay -v vgNN > /tmp/vgNN.txt
That tells you how which disks/LUNs are used and how big they are.
Then ioscan -fn > /tmp/ioscan.txt
This will allow you to map the disks in the vgdisplay to hardware paths.
Then once you have plugged the VA7110 into the switch, do another ioscan -fn and compare the output with the previous ioscan. This will help you work out what the new names for the disks are and therefore which device names to use in the vgimport.
Apart from that the steps in the postings above are a good guideline.
