C100 HDS Software Update
Software Installation on a Redundant Blackrock System
Installation of software and support files on a redundant Blackrock system must be performed on one processor at a time
with the other processor powered down. Do not attempt this process with both units running!
1. Check the contents of the Software Upgrade Kit against the packing list; if there are any omissions, please contact your
local SSL office before proceeding further.
Archiving the System Disk
2. As with all software installations, we strongly advise you to generate a 'mirror' copy of the C100 HDS System Disk
before proceeding. Open the SSH client on the networked computer and login to the C100 HDS system
(ref. Assumption A4.). Once you are logged in (as user 'sbc'), type:
backup_system_disk <CR>
The backup process copies the entire C100 HDS System Disk and so will take a considerable time (≈15min) to complete.
It is of course also recommended that any backups created are stored off-line elsewhere. This must be done separately
for both Blackrock processors – but this can be done on both processors simultaneously.
3. To ensure that sufficient space is still available to contain the upgrade, on each system type:
df -h /home <CR>
Installing the Support Software
4. Ensure that the slave Blackrock processor has been powered down. Proceed through the following steps on the master
processor first.
5. Place the C100 HDS Software Disk in the DVD drive in the networked computer and open a window that displays
the contents of the DVD – do not place the software disk in the DVD drive on the Blackrock processor!
6. Locate the 'updates' folder within the folders exported by the C100 HDS system (ref. Assumption A5.).
7. On the DVD, open the 'C100_V2_0_7 Updates' folder and drag the following three .rpm files from the CD into the
'updates' folder:
• kernel
• ssl_console_files
• ssl_host_tools
8. Once the .rpm files have been copied, return to the SSH client and type:
install_updates <CR>.

This will create a time and date stamped backup file in the
'system_backup' folder.
Check that the percentage used is less than about 90%. If it
is higher, consider removing any old backups from the
'system_backup' folder.

This will unwrap and install each of the .rpm archives. Follow
the on-screen instructions to install them. Ignore any error
messages printed to the terminal during this time.
