3.6.0 Matrix Server 3.6.0 Administration Guide (5697-7081, December 2007)

Chapter 19: SAN Maintenance 257

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.)

NOTE: OLI of new storage can cause an interruption of normal

operations on your storage device. Because of this, it is

recommended that OLI of new storage be scheduled for off-peak

hours.

When the appropriate 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

reboot the servers after inserting a new disk. The disk will then be visible

to the matrix.

Online Replacement of a FibreChannel

Switch

This procedure applies only to sites using EMC PowerPath.

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.
