moving ASM disks to another SAN

Hi All,

We are in the process of migrating our disks to another SAN. In the process, we are creating new disks on different LUN and adding the new disks and dropping the old ones. The new disks that are being added are bigger than the old ones. For example, all the new disks will be created of size 1TB.

Here is one example where we are migrating to new disks using the alter diskgroup command:

alter diskgroup DG_TIER1_01

add disk 'ORCL:VNX_DATA1_01','ORCL:VNX_DATA1_02','ORCL:VNX_DATA1_03','ORCL:VNX_DATA1_04'     

drop disk DMX4_TIER1_01,DMX4_TIER1_06,DMX4_TIER1_07,DMX4_TIER1_08,DMX4_TIER1_09;
