root@ngeAIX# lsdev -Cc disk
hdisk0 Available 21-T1-01 3PAR InServ Virtual Volume
hdisk1 Available 21-T1-01 3PAR InServ Virtual Volume
root@ngeAIX# cfgmgr
root@ngeAIX# lsvg -p rootvg
rootvg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk0            missing           199         12          00..00..00..00..12

Solution

root@ngeAIX# bootinfo -b
hdisk0

### varyonvg will correct the issue.
root@ngeAIX# varyonvg rootvg
root@ngeAIX# lsvg -p rootvg
rootvg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk0            active            199         12          00..00..00..00..12
hdisk1            active            199         12          00..00..00..00..12
root@ngeAIX#

vryonvg activates the volume group, and due to this, all physical partitions are synchronized if they are not current.
And the disk which got missed earlier due to some storage issue is now back in place.
However you should be cautious running this command, as it may remove the disk as well from the system.
