Staring with AIX 7.3.2, the nimadm tool can now display the date and time at each phase of a migration. Handy for troubleshooting. The -A flag will display this timestamp information.

-A Adds a timestamp at the start of each phase of the nimadm operation. The timestamp is displayed in MM-DD-YYYY HH-MM-SS format.end of change

For example:

# oslevel -s

7300-02-01-2346

# nimadm -A -j nimadmvg -c aixmig -s spotAIX73TL1SP1 -l AIX73TL1SP1 -d hdisk1 -Y

# grep -i "Executing nimadm phase" aixmig_alt_mig.log
