clarion cx700 to cx3-80 migration

[nskbalu]

What would be the default steps if we want to migrate the storage EMC clarion cx700 to cx3-80 in HPUX box?

Please elaborate the same.

I believe you are in the wrong forum! This one is meant for HP storage related discussions.

You should either go to the HP-UX or an EMC forum.

The steps can be that same for migrating between and two sets of arrays. For example, I used these to go from an clariion to an EVA.

There are of course other methods, but this allows an online migration.

Steps to migrate a VG (ex vg01)

1. Note the LUNs that make up the VG and the size of each (e.g. 3 LUNs of 100GB each)

2. Create the same number of LUNs of the same size on the second array (RAID type doesn't have to be the same)

3. Present the new LUNs to the HPUX server and do an ioscan and insf.

4. Do a pvcreate on each of the new luns.

5. Add the new LUNs to the VG using vgextend.

6. Use pvmove to move all the extents from an old LUN to a new LUN.

7. Once the old LUNs are empty - use vgreduce to remove them from the volume group.

8. unpresent the old LUNs on the old array.

9. redo the ioscan and use rmsf to remove the NO_HW devices that were on the old array.
