On a 

Sun Enterprise 3500 platform, the mirror layout must always be 

based upon the bays in which the disks are installed. Submirrors 11, 15, 
and 19 are the disks in the lower bay (targets 0 through 3 on controller 0); 
submirrors 12,16, and 20 are the disks in the upper bay (targets 4 
through 7 on controller 1). The table below shows the mirror layout.

In order for your CMS system to be mirrored, it must have the following 
hardware installed in addition to the hardware already installed:

●

For a 

Sun Enterprise 3500 system, two GigaByte Interface 

Converter (GBIC) modules. One will be installed into the UA slot on 
the FC-AL Interface board, and the other will be installed into GBIC 
Port 1 on the Sbus I/O board (see the illustration on page 15).

●

For a 

Sun Enterprise 3500 system, a fiber cable to connect the UA 

port GBIC to GBIC Port 1 on the I/O board.

●

Twice the number of disk drives needed for an unmirrored system. 
All the disks must be the same size.
