Prepare Host or Plan Run on an AIX Remote Agent May Fail (2960)

Performing a Prepare Host or Plan Run on an AIX Remote Agent may fail if the target has a stale NFS mount on the / directory. For example, when a CD-ROM is mounted from a remote server onto a target and then the CD-ROM is removed from the remote server, a stale NFS file mount is left on the target. A stale NFS mount is also created if a remote server goes down and the target still has one of its file systems mounted. In these cases, if the file system is not properly unmounted then Plan Run and Host Prepares will hang while the software attempts to resolve this stale NFS reference. The same behavior occurs if an ls command is issued on this file system directory. Either a plan timeout will occur or the NFS timeout will terminate the Plan Run or Host Preparation.

Workaround: Enable Fast Preflight during a Plan Run. The NFS checks are only done during regular Preflight. In addition, prior to preparing a target server or running a plan, ensure that all NFS mounts are resolvable and valid.
