Hi,
We got a server running
AIX 5.3, that rebooted the other day, and now keeps on reporting hdisk errors althouth the errors are of type temp.
The disk are configured in a vpath, and I noted that some phantom disks have appeared in the vpath config showing no physical size.
Looking for some recommendations, as I believe these phantom drives may be causing the disk errors. Below some output.
