Can a FlexArray back-end LUN that is used in an aggregate be replaced with another?
Applies to
- NetApp FAS/AFF
- FlexArray back-end
Answer
- A FlexArray back-end array LUN that is used in an aggregate cannot be replaced with another LUN
- Normally, the command storage disk replace can be used to replace a disk used in an aggregate with another
- Redundant data is used to rebuild the source disk's data onto a spare disk
- The newly built disk takes the place of the source disk in the aggregate
- The source disk beciomes a spare
- However, with FlexArray back-end LUNs, aggregates are typically in a RAID-0 configuration
- Redundancy is not used on the NetApp side because the back-end array already takes care of redundancy for data protection
- Since there is no redundancy in the aggregate, the command storage disk replace cannot work
- If LUNs in an aggregate need to be replaced, a more roundabout way is recommended
- Create a new aggregate
- Use vol move to move all volumes from the source aggregate to the new aggregate
- Destroy the source aggregate
