I am going to use EMC disks for AIX systems. What do hdisk and hdiskpower represent?
IN AIX, we just say hdisk, but with EMC, we have hdisk and hdiskpower.

thx much

hdisk can be considered a path to a disk, and the hdiskpower is the disk under Powerpath control.
If you have a disk with 2 paths, you'll have hdisk1 & hdisk2 which together form hdiskpower1.

a useful command for you will be:

powermt display dev=all

This will show you which hdisks belong to which hdiskpower and the current path status.
