Nondisruptive operations with HA pairs

By taking advantage of an HA pair's takeover and giveback operations, you can change hardware components and perform software upgrades in your configuration without disrupting access to the system's storage.

You can perform nondisruptive operations on a system by having its partner take over the system's storage, performing maintenance, and then giving back the storage. Aggregate relocation extends the range of nondisruptive capabilities by enabling storage controller upgrade and replacement operations.
