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.
The operations are as follows:
Dynamic LUN removal from an existing target ID
Dynamic new LUN addition to a new target ID
Dynamic LUN expansion
Changing the LUN characteristics
See Changing the characteristics of a LUN from the array side.
