List,
We have a need to restructure our underlying ASM devices to 20T from 10T to
reduce the number of luns assigned to a host.
The Total DiskGroup SIze is 163840.00 GB (~ 160 TB) made up of 10TB
devices. (16 Devices)
Our storage admins would like to move these to 20T devices and halve the
number of physical devices presented.
I know ASM devices should be the same size when you rebalance.
I know *one* option is to add the 8 20T devices as candidates and create a
new diskgroup and move the data to the new diskgroup and then drop the old
10T devices from ASM.
Is that the *only* option here? Anyone have additional
suggestions/thoughts?
Chris
