The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.

Mirror pools in AIX allow administrators to define specific sets of disks that can be used for mirroring logical volumes. This feature provides greater control over the allocation of mirror copies, ensuring that each copy is placed on separate, specified disks to improve data redundancy and reliability. This setup helps in managing disk utilization and performance more efficiently. The other options do not accurately describe the primary benefit of mirror pools.References:= IBM AIX Documentation

In AIX, error entries related to a system crash are preserved by writing them to Non-Volatile Random Access Memory (NVRAM). These entries are processed and logged to the system error log when the system comes back up. This ensures that critical error information is not lost during a system crash.References:= IBM AIX Documentation
