3.4.0 Matrix Server Administration Guide

Chapter 5: Configure the SAN 53

The higher-numbered partitions will continue to work correctly;

however, you should be aware of the following:

• A new volume cannot include subdevices having partition numbers

above 31. Existing volumes cannot be extended to include the higher-

numbered partitions.

• You will not be able to take a hardware snapshot of partitions with

numbers above 31.

• A single Alert will be issued if any disks or volumes in the matrix

contain unsupported partitions. The Alert will remain until the disks

with unsupported partitions are deported.

Import SAN Disks

SAN disks to be used for PSFS filesystems must be imported into the

matrix. This step gives the matrix control over access to the disks. Before

importing disks, you should be aware of the following:

• 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.

• Only basic disks can be imported. Dynamic disks are not supported.

• Shared disks must be partitioned before they are imported into the

matrix. If there is not a partition table in place on the disk, you will not

be able to access it via Matrix Server.

If you want to extend a PSFS filesystem and the underlying partition,

you can use the Extend option provided on the PolyServe

Management Console. To make other changes to the partition table

after a disk has been imported, you will need to deport the disk, make

the changes with the Windows Disk Management utility, and then

import the disk again.

• Matrix Server supports a maximum of 31 partitions on a disk. Disks

containing a larger number of partitions cannot be imported into the

matrix.
