Using single-path storage devices
Support for single-path storage devices is different depending on your operating environment.
AIX®
- Harvested
IBM.AgFileSystem
resources can be automated.IBM.AgFileSystem
resources are harvested if they are of typejfs
orjfs2
and reside on storage entities that are harvested themselves (storage entities of classIBM.LogicalVolume
,IBM.VolumeGroup
,IBM.Disk
. - User-defined
IBM.AgFileSystem
resources can be automated, for example, network file systems. - SCSI-2 reservation is supported.
- No striping
- User-defined
IBM.AgFileSystem
resources can only be automated if the disk hosting the file system has the same device name on all nodes of the cluster.

- Support for SCSI reservation is limited. Perform a disk reserve operation to check whether SCSI reservation is available.
- User-defined
IBM.AgFileSystem
resources can only be automated if the disk hosting the file system has the same device name on all nodes of the cluster.
Linux on System z®
Device mapper provided or md devices are harvested as IBM.Disk
resources if a
physical volume has been created on the md device using the pvcreate
command.
- Only user-defined
IBM.AgFileSystem
resources orIBM.AgFileSystem
resources residing on harvested device mapper provided or md devices can be automated. Resource harvesting for other disks is not supported. Even if harvesting of other disk resources is successful, the harvested resources cannot be automated. - User-defined
IBM.AgFileSystem
resources can only be automated if the disk hosting the file system has the same device name on all nodes of the cluster. - SCSI reservation is not supported.
