How to upgrade an Enterprise platform to disk mirroring

Step 2: Install the mirror disks on an

Enterprise 3500

system

Do this step only if you have an Enterprise 3500 system.

It is likely that your Enterprise 3500 system is currently using controller 1 (c1) for the internal CD-ROM drive. This step associates the CD-ROM drive with controller 2 (c 2) so controller 1 will be free for the new disk drives. In this step you also install some additional hardware for controlling the new disks, and install the new disks themselves. You should be logged in as root before beginning this step.

1.Enter the following command:

______________________________________________________

# ls -l /dev/dsk/c1t6d0s0

______________________________________________________

The system should respond with a line similar to the following:

______________________________________________________

lrwxrwxrwx 1 roor roor 50 Nov 16 08:58 /dev/dsk/c1t6d0s0 -> ../../devices/sbus@3,0 /SUNW,fas@3,8800000/sd@6,0:a

______________________________________________________

Notice that c1t6d0s0 is pointing to sd@6,0:a. That indicates that controller 1 is being used by the CD-ROM drive. Remove that association by entering the following commands:

______________________________________________________

#rm /dev/dsk/c1*

#rm /dev/rdsk/c1*

#touch /reconfigure

#/usr/sbin/shutdown -y -g0 -i0

______________________________________________________

2.Install new hardware components as follows:

Install a GigaByte Interface Converter (GBIC) into slot UA on the Interface board.

Install another GBIC into port 1 on the SBus I/O board.

Install a fiber cable between the two newly installed GBICs.

The illustration below shows where the GBICs are installed. For more detailed information, see CentreVu CMS Sun Enterprise 3500 System (connectivity diagram) (585-215-877), which was packed with your system.
