Operational restrictions

The success of some LUN Manager activities depends on the status of the security switch and whether I/O

is active or inactive to the port or LUN. The following tables describe those restrictions.

NOTE:

• Do not remove LU paths (see ”Changing or viewing LU path settings” on page 26) when the hosts are

performing I/O processing.

• Do not remove LUN security (see ”Applying and removing LUN security” on page 31) when the hosts

are performing I/O processing.
