Unofficial Cisco MDS Data Mobility Manager Configuration Guide Errata

When the jobs are created on both SwitchA and SwitchB, the server HBA pwwn is used. This is incorrect. In storage based migration you need to use the virtual initiator. In previous parts of “Configuring a Session” the correct VI information is used for zoning etc. But when it comes to session creation incorrect information is shown.

There are numerous issues with this section, all listed below. I recommend someone go through and double check all the pwwn’s being used in this section because there are a lot of mistakes.

Ex:

Incorrect
Configure the data migration job on switch A:
switchA# configure terminal
switchA(config)# dmm module 8 job 2345 create
Started New DMM Job Configuration.
Do not exit sub-mode until configuration is complete and committed
switchA(config-dmm-job)# server vsan 100 pwwn 50:06:0b:00:00:11:b9:18
switchA(config-dmm-job)# storage vsan 100 pwwn 50:06:04:82:bf:cf:e0:43 existing
switchA(config-dmm-job)# storage vsan 100 pwwn 50:06:0e:80:03:4e:95:13 new
switchA(config-dmm-job)# peer 10.10.2.4
switchA(config-dmm-job)# attributes job_type 2 job_mode 1 job-rate 1 job-method 1
switchA(config-dmm-job)# commit
switchA(config-dmm-job)# end
Ending DMM Job Configuration.
If the Job was not committed, it will be required to reconfigure the job.

Correct
Configure the data migration job on switch A:
switchA# configure terminal
switchA(config)# dmm module 8 job 2345 create
Started New DMM Job Configuration.
Do not exit sub-mode until configuration is complete and committed
switchA(config-dmm-job)# server vsan 100 pwwn 21:0d:00:0d:ec:02:2d:82
switchA(config-dmm-job)# storage vsan 100 pwwn 50:06:04:82:bf:cf:e0:43 existing
switchA(config-dmm-job)# storage vsan 100 pwwn 50:06:0e:80:03:4e:95:13 new
switchA(config-dmm-job)# peer 10.10.2.4
switchA(config-dmm-job)# attributes job_type 2 job_mode 1 job-rate 1 job-method 1
switchA(config-dmm-job)# commit
switchA(config-dmm-job)# end
Ending DMM Job Configuration.
If the Job was not committed, it will be required to reconfigure the job.

Incorrect
Configure the data migration job on switch B:
switchB# configure terminal
switchB(config)# dmm module 8 job 2345 create
Started New DMM Job Configuration.
Do not exit sub-mode until configuration is complete and committed
switchB(config-dmm-job)# server vsan 100 pwwn 21:01:00:e0:8b:0a:5d:e7
switchB(config-dmm-job)# storage vsan 100 pwwn 50:06:04:82:bf:cf:e0:5d existing
switchB(config-dmm-job)# storage vsan 100 pwwn 50:06:0e:80:03:4e:95:03 new
switchB(config-dmm-job)# peer 10.10.1.8
switchB(config-dmm-job)# attributes job_type 2 job_mode 1 job-rate 1 job-method 1
switchB(config-dmm-job)# commit
switchB(config-dmm-job)# end
Ending DMM Job Configuration.
If the Job was not committed, it will be required to reconfigure the job.

Correct
Configure the data migration job on switch B:
switchB# configure terminal
switchB(config)# dmm module 8 job 2345 create
Started New DMM Job Configuration.
Do not exit sub-mode until configuration is complete and committed
switchB(config-dmm-job)# server vsan 100 pwwn 21:0d:00:0d:0a:01:2b:82
switchB(config-dmm-job)# storage vsan 100 pwwn 50:06:04:82:bf:cf:e0:5d existing
switchB(config-dmm-job)# storage vsan 100 pwwn 50:06:0e:80:03:4e:95:03 new
switchB(config-dmm-job)# peer 10.10.1.8
switchB(config-dmm-job)# attributes job_type 2 job_mode 1 job-rate 1 job-method 1
switchB(config-dmm-job)# commit
switchB(config-dmm-job)# end
Ending DMM Job Configuration.
If the Job was not committed, it will be required to reconfigure the job.

Also the zoning is incorrect on this same page. The zoning for Fabric B is just the same information for Fabric A which is not correct. Someone just copied and pasted, but Fabric B has its own set of unique information

Incorrect
Configure the zone and zoneset on switch B:
switchB(config)# zone name DMM1 vsan 100
switchB(config-zone)# member pwwn 21:0d:00:0d:ec:02:2b:82 vi
switchB(config-zone)# member pwwn 50:06:04:82:bf:cf:e0:5d es
switchB(config-zone)# member pwwn 50:06:0e:80:03:4e:95:03 ns
switchB(config-zone)# exit
switchB(config)# zoneset name DMM1 vsan 100
switchB(config-zoneset)# member DMM1
switchB(config-zoneset)# exit
switchB(config)#

Correct
Configure the zone and zoneset on switch B:
switchB(config)# zone name DMM1 vsan 100
switchB(config-zone)# member pwwn 21:0d:00:0d:0a:01:2b:82 vi
switchB(config-zone)# member pwwn 50:06:04:82:bf:cf:e0:5d es
switchB(config-zone)# member pwwn 50:06:0e:80:03:4e:95:03 ns
switchB(config-zone)# exit
switchB(config)# zoneset name DMM1 vsan 100
switchB(config-zoneset)# member DMM1
switchB(config-zoneset)# exit
switchB(config)#

Incorrect new storage targets are used for Fabric A
