Reboot system
第8题:
check the output of the vmstat command on LINUX
check the performance reports via Tivoli Storage Productivity Center for Data
check the performance reports via Tivoli Storage Productivity Center for Disk
check the output of the iostat command on AIX
第9题:
Low paging
High paging
Workload manager is not turned on
A high run queue length
第10题:
The iostat can only be run as the root user
There could be zero percent I/O wait and still be an I/O bottleneck
Any I/O wait time displayed in output of iostat is an indication of severe I/O bottlenecks
Running iostat without any arguments/parameters is sufficient for resolving I/O bottlenecks
