Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy

Table 2 Validating Metrocluster package (continued)
Cannot confirm if the disks are being replicated
in case they are being used as raw disks or in
case they belong to an Oracle ASM diskgroup.
Skips this verify on VxVM diskgroups if the naming
convention used by VxVM is legacy and if the
controller ID is greater than 512 (This happens
when VxVM uses an internal format to recognize
devices that do not support legacy dsf format).
Also skips the verify if the naming convention is
enclosure based. In such cases, you can change
the naming scheme using the vxddladm command
so that VxVM output shows the disk names in a
persistent dsf format.
When the package is up and running, the
