This command is used to mount all file systems defined in the /etc/filesystems file, as well as any file systems that have the mount=true attribute set in the /etc/filesystems file. According to the IBM AIX v7 Administrator Specialty Study Guide, "the mount -a command mounts all file systems specified in the /etc/filesystems file, including file systems with the mount=true parameter set. The mount -a command is normally issued at system startup or when a new file system is added to the system."
Question # 5
What command is used to monitor SAN I/O performance/throughput?
The command used to monitor SAN I/O performance/throughput is iostat -DIRT 60 10. The iostat command is used to monitor I/O performance and throughput on a SAN device. The DIRT (Disk I/O Response Time) flag can be used to display the response time for each I/O request. The last two arguments, 60 and 10, are the interval (in seconds) and the number of iterations respectively. This command will monitor I/O performance/throughput every 60 seconds for 10 iterations.
Question # 6
What AIX feature will allow data to be mirrored to a remote site?
Geographic Logical Volume Manager (GLVM) is an AIX feature that allows data to be mirrored to a remote site [1][2], enabling disaster recovery and improved data availability. GLVM creates a single, unified view of the data across multiple sites, allowing the data to be managed and accessed as if it was all stored in one location.
