Which backup-archive client host operating system requires the use of a dsm.sys file?
A . UNIX/Linux
B . Microsoft Windows workstation system
C . any server in a Microsoft Windows cluster
D . Microsoft Windows server 2008
Answer: A
Explanation:
Configure the IBM Spectrum Protect client
After installing the backup-archive client, you must configure it before performing any operations.
The following applies to AIX, Linux, Solaris, and Mac OS X.
If you are upgrading the backup-archive client, it is unnecessary to reconfigure the scheduler, web client, or other configuration settings. If the dsm.opt and dsm.sys files used by the previous client installation are available in the default installation directory or the directory or file pointed to by the DSM_CONFIG and DSM_DIR environment variables, the client accesses these files for configuration information.
