AIX defined disks to remove
Hello,
On a AIX system, I see many "defined" disks when executing "lsdev -CCdisk" command, the disks are
still there but the hdiskpowerX and hdiskX numbers X have changed, the applications are working.
I want to get the right kdiskpower numbers, I think that I should remove all the disks first (rmdev) and
execute "cfgmgr", is it right ? Or should I clean powerpath ?
Thanks

hdiskpower or hdisk display as "defined" ? The "defined" state normally means the device is inaccessible from host.

Right, the device in "defined" state cannot be reached from host, but the system has created another hdiskpower and
the applications are working, my problem is to cleanup everything by removing all the "defined" state and getting the
good hdiskpower numbers.

If you make sure your applications are working on the available hdiskpower devices without any single path failure or any "defined" state of hdisks managed by PowerPath and the hdiskX you're going to remove are never used, try rmdev -dl hdiskX will removed the old definition of hdisk, then after run cfgmgr, the hdisk wouldn't appear again.
