3.5.1 Matrix Server Administration Guide

Chapter 2: Matrix Administration 20

server must not be established while Matrix Server is running on the

server.

• 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.

• The Linux kernel can access only partitions 01 through 15 on SCSI

disks. However, the fdisk and cfdisk utilities allow you to create

partitions with numbers greater than 15. If you use these utilities for

partitioning SCSI disks, be sure that partition 15 is the highest-

numbered partition.

• Matrix Server supports 2 TB filesystems on basic volumes. For a 64-bit

operating system, Matrix Server supports up to 128 TB filesystems on

dynamic volumes. For a 32-bit operating system, Matrix Server

supports up to 16 TB filesystems on dynamic volumes.

• If servers from multiple matrices can access the SAN via a shared FC

fabric, avoid importing the same disk into more than one matrix.

Filesystem corruption can occur when different matrices attempt to

share the same filesystem.

Matrix Software Requirements

The operating system and PolyServe software must be installed

consistently across the servers in the matrix. When configuring your

servers, you should be aware of the following requirements:

• All servers must be running versions of the operating system and

kernel that are supported by Matrix Server.

• All servers in the matrix must use the same operating system

architecture (either 32-bit or 64-bit).

• The servers in the matrix can be running different supported versions

of the same operating system type as long as the above rules are met.

• Matrix Server must be installed on all nodes in the matrix. If MxFS-

Linux or MxDB-Oracle-HiAv is used, it must be installed on all nodes.
