Unsuppressing DMP for EMC PowerPath disks
This section is only applicable if you want to upgrade a system that includes EMC PowerPath disks.
In releases of VxVM before 4.1, a combination of DMP subpaths and the controllers of DMP subpaths were usually suppressed to prevent interference between DMP and the EMC PowerPath multi-pathing driver. Suppression has the effect of hiding these subpaths and their controllers from DMP, and as a result VxVM cannot see the disks on these subpaths and controllers.
VxVM 4.1 and later releases have the ability to discover EMCpower disks, and configure them as autodiscovered disks that DMP recognizes are under the control of a separate multi-pathing driver. This has the benefit of allowing such disks to reconfigured in cluster-shareable disk groups. Before upgrading to VxVM 7.4.1, you must remove the suppression of the subpaths and controllers so that DMP can determine the association between EMCpower metadevices and c#t#d# disk devices.
In the following scenarios, you may need to unsuppress DMP subpaths and controllers:
Converting a foreign disk
Converting a defined disk
Converting a powervxvm disk
Because EMCpower disks are auto-discovered, the powervxvm script should be disabled and removed from the startup script. To remove the powervxvm script, use the command:
# powervxvm remove
