For Native Multipathing on AIX, best practice is to use the following settings for MPIO:
algorithm = round_robin (other algorithms may also be used)
hcheck_cmd = inquiry
queue_depth = 32
reserve_policy = PR_shared*
*reserve_policy may be set to no_reserve as long as GPFS/SCSI3 clusters are not part of the planned migration.
Check if a “PR_key_value” is already assigned prior to changing the “reserve_policy” to PR_shared.
