3.1.2 Matrix Server Administration Guide

Chapter 18: SAN Maintenance 242

Online Insertion of New Storage

Matrix Server supports online insertion (OLI) of new storage, provided

that OLI support is present for your combination of storage device, SAN

fabric, HBA vendor-supplied device driver, and the associated HBA

vendor-supplied libhbaapi. (Check with your vendors to determine

whether OLI is supported.)

When this lower-level OLI support is in place, inserting a new disk will

cause a new device to automatically become eligible for importing. The

disk can be imported with the Management Console or mx utility, and

can be used normally from that point forward.

If OLI is not possible with your hardware combination, you will need to

restart Matrix Server after inserting a new disk. The disk will then be

visible to the matrix.

FibreChannel Switch Maintenance

Changes to Switch Modules

Changing the hardware configuration, such as adding or replacing switch

modules, is not supported while Matrix Server is running. This restriction

applies only to FibreChannel switches that are under the control of

Matrix Server.

Online Replacement of a FibreChannel Switch

When a matrix includes multiple FibreChannel switches, you can replace

a switch without affecting normal matrix operations. The following

conditions must be met when performing online replacement of a

FibreChannel switch:

• The replacement switch must be the same model as the original switch

and must have the same number of ports.

• The FC connectors must be reinserted in the same location on the new

switch. For example, the FC connector that was plugged into port 1 on

the original switch must be plugged into port 1 on the new switch.

• Matrix Server must be stopped on any servers that are connected only

to the switch to be replaced.
