How to upgrade an Enterprise platform to disk mirroring 14
Step 2: Install the
mirror disks on an
Enterprise
3500
system
2
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
