host system, and/or additionally installed peripherals.
The used host bus adapter is unavailable
for the disk array unit. Use the host bus adapter available for the disk array

8.2 Computer Virus
A computer virus is a program that is intentionally designed to cause damage to a third party's
programs or databases
The program can replicate itself or use another system function to infect other systems by copying
itself into other programs. The appearance of symptoms of virus infection can be delayed by having
the system wait for a specific point in time, a specific period of time, or a specific number of
transaction executions. The virus may destroy programs, data, or other files or causes systems to
operate in a way not intended by the designers.
To suppress the risk of damage to a minimum level, take proper measures such as a regularly
scheduled backup of important data.
