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.

The root user is not required to run SMIT, and the size of the window is the only factor that determines the minimum output display requirements. According to the IBM AIX v7 Administrator Specialty Study Guide (page 9-3), SMIT requires 24 lines and 80 columns for the output display for successful execution.

When attempting to recover a corrupted file system, the administrator should first confirm that the file system is not mounted. If the file system is not mounted, then the administrator should run the fsck command with the -F (force) flag. This will force the fsck command to check the file system for errors and attempt to fix them. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 8-23).

The administrator has failed to run the cfgmgr command before rebooting the systems. Running the cfgmgr command before rebooting a system is important, as it ensures that any changes made to the configuration are written to the system, otherwise the changes may be lost when the system is rebooted. Other commands such as chdev and route add are not related to this issue and will not solve the problem.

For more information on the cfgmgr command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 10-7. The guide can be found here: https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/cfgmgmt/cfgmgr_command.htm.

The procedure to check which system tunables have been changed in the system since last boot is to run the 'lstuncfg -1 | grep -v DEFAULT' command. The lstuncfg command is used to display the current configuration of the system tunables. By using the '-1' option, the command will display the system tunables and whether they have been changed since the last system reboot. The 'grep -v DEFAULT' command will filter out the default values, allowing you to see only the tunables that have been changed. This command is available on IBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. For more information, please see the IBM documentation at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds2/lstuncfg.htm.
