On the lspv output I noticed 4 of 8 hdiskpower devices without PVIDs - those PVIDs are now seen on plane EMC's hdisk devices. But then I check in "powermt display dev=all" I see all hdiskpower devices with complete number of paths (corresponding hdiskX devices). Also lsdev -Cc disk shows all hdiskpower and EMC's plane hdisks available. No changes were done on system side since several weeks so I am surprised what could happen..

Anyone has an idea what could happen and how to fix it online (service can't be stopped right now)?
The system is AIX 5.3 TL11 SP4
