cfgadm –c configure c5
Once the paths are online, the cancel revert can be resumed by performing an NDM recover operation.
WINDOWS 2012 WITH MPIO
Use default MPIO settings with the following parameters enabled:
PathVerifyEnabled - Enable for optimal results with path discovery.
PathVerificationPeriod - Set a time in seconds for automatic path detections. Dell EMC recommends setting it to lowest allowed value
between 10 and 30 seconds.
VERITAS DYNAMIC MULTI-PATHING
Configure DMP tunable parameters to NDM required values from the application host:
Check and modify the following DMP tunable parameters. If the parameter values are not set to the default values,
note settings so the parameters can be returned to expected values following NDM migration.
DMP Tunable Parameter Default Value NDM Required Value
dmp_path_age 300 0
dmp_health_time 60 0
dmp_restore_interval 300 10
dmp_restore_cycles 10 10
iopolicy (per DMP node name) MinimumQ MinimumQ
When these values are not set, the cancel –revert will not work correctly.
Use the rescan command.
On Linux: /usr/bin/rescan_scsi_bus.sh followed by vxdisk scandisks to detect new paths. Use vxdmpadm to verify that the
new paths are added.

ESXI WITH NATIVE MULTI-PATHING
Use the rescan command to detect new paths, or wait for NMP to detect the paths automatically.
To reduce the delay in automatic detection, change to 30 seconds.
To set the path polling time, login to the host and navigate to Configuration -> Advanced Settings -> Disk and update the
Disk.PathEvalTime field.
APPENDIX B: AIX, GPFS, ORACLE RAC, POWERHA AND POWERPATH WITH NDM
Properly configuring multiple paths to the host with AIX 6.1/7.1/7.2, GPFS, ORACLE RAC 11gR2/12cR1, POWERHA 6.1/7.1/7.2 and
PowerPath 5.7SP2/6.0 requires an additional step when performing an NDM migration. Please review the details in this appendix prior
to migrating such environment.
