About online dynamic reconfiguration

You can perform the following kinds of online dynamic reconfigurations:

■ Reconfiguring a LUN online that is under DMP control

■ Updating the array controller firmware, also known as a nondisruptive upgrade

■ Replacing a host bus adapter (HBA) online

Reconfiguring a LUN online that is under DMP control

System administrators and storage administrators may need to modify the set of

LUNs provisioned to a server. You can change the LUN configuration dynamically,

without performing a reconfiguration reboot on the host.

Dynamic LUN reconfigurations require array configuration commands, operating

system commands, and Veritas Volume manager commands. To complete the

operations correctly, you must issue the commands in the proper sequence on

the host.
