SAN Copy /Incremental

your regular and final incremental would be as simple as this:

NaviSeccli.exe -user Aadmin -password  password -scope 0 -address  10.1.8.30 sancopy -start -name Lun546to19C8

Thanks Dynamox. I am learning so much from you.... I dont know if i am asking this question in the correct thread or not. Before i can start the SAN Copy session we need to create LSAN zones. One of our team member created the lsan zones in the below way.

Source CHA-A

Zone Name :lsan_Cla_3658_spa0_spb0_Cla_0568_spa0_spb0

                  50:06:01:60:39:a0:2a:15 EXIST

                  50:06:01:68:39:a0:2a:15 EXIST

                  50:06:01:60:39:a0:10:d5 Configured

                  50:06:01:68:39:a0:10:d5 Configured

CHA -B

Zone Name :lsan_Cla_3658_spa1_spb1_Cla_0568_spa1_sp1

                   50:06:01:61:39:a0:2a:15 EXIST

                   50:06:01:69:39:a0:2a:15 EXIST

                   50:06:01:61:39:a0:10:d5 Configured

                   50:06:01:69:39:a0:10:d5 Configured

On the Target side also the LSAN Zones were created in the same way. What i observed is the lsan zone information on the source Brocade Router side was propagated to Broaced fabric on the source side but the LSAN Zone info on the target Brocade Router side is not propagated into the target Brocade fabric. Becuase of this i was not able to establish a SAN copy session between two clariion arrays. Can anyone please tell me if the LSAN Zones are configured properly or not.

Brocade Router - 7500

glad to help

I would ask your Brocade/zoning question in the infrastructure section of this forum.

Dynamox,

I was able to create the LSAN zones sucessfully.

1) Created a storage group on the target and added the lun .

2) Updated SAN Copy connections on the target side Storage group was able to see the Source clariion SPA and SPB..

3) Created a SAN copy session. (was created successfully)

4) When i am trying to start the session using copywholelun -nomark option the command is failing and i am getting the below error

naviseccli -h 10.71.229.112 sancopy -start -name SANcopy_test -copywholelun -nomark all

sancopy command failed  

error returned from agent.

Copy session has destination error.

Any suggestions ...

1. do you have luns in the reserve lun pool?

2. does it work using the GUI wizard?

3. are your commands targeting the correct SP?

Dynamox,

I Have  2 questions?

I'm having considerable time gap and large amount of data being changed between Initial session starting with -copywholelun -nomark all  option and Final Cut Over with Host shutdown,can I safely start session with regular option 2 as mentioned below as many time as I want and data will be consistent?

1.Start Incremental SAN Copy session while host is online
NaviSeccli.exe -h sancopy -start -name   -copywholelun -nomark all

2.Start a regular session once  above session is completed(Inconsistent) to reduce the time required to finish Final Push of Changed data.

NaviSeccli.exe -h sancopy -start -name

3.Shutdown Host and complete Final Push.

NaviSeccli.exe -h sancopy -start -name

Is there any way to find How much Data is changed after starting session with -copywholelun -nomark all  option?

Thanks

Thanks a lot

Hi Dynamox,

Sorry for posting this and eating your time, as this is an old post.......

I have got 3 questions ...

1) If a SAN Copy will fail what will happen to the sessions, when it's restarted, will it be Full Copy or incremental ?

2) If it is incremental, what are the pre-requisites to make it incremental...we need license for that (if i am not mistaken) and what else ?

3) Which ports are reserved for it in VNX & clariion & how many zones are recommended ?

Thanks in advance

Is it required to shutdown the source host when we do a full SAN copy?

not for push, will need to shutdown for final push.
