====== Spectrum Protect node replication ======

===== Spectrum Protect server config for replication v8.1.13+ =====

To replicate all nodes except node3:
<cli prompt='>'>
server1> q fscounts *
server1> def stgrule repl-2-server2 server2 actiontype=replicate
server1> def substgrule repl-2-server2 repl-2-server2-sub1 node3 actiontype=norepl
server1> q substgrule repl-2-server2 f=d
server1> q stgrule repl-2-server2
server1> start stgrule repl-2-server2
</cli>

To replicate only specific nodes, or filespaces
<cli prompt='>'>
server1> q fscounts *
server1> def stgrule repl-2-server3 server3 actiontype=norepl
server1> def substgrule repl-2-server3 repl-2-server3-sub1 node3 actiontype=repl
server1> def substgrule repl-2-server3 repl-2-server3-sub2 node2 actiontype=repl filespace=/data2
server1> q substgrule repl-2-server3 f=d
server1> q stgrule repl-2-server3
server1> start stgrule repl-2-server3
</cli>

===== Repair stgpool container with replication =====

<cli prompt='>'>
server1> audit container stgpool=container1 
server1> q damage container1
server1> repair stgpool container1 server2
</cli>

Then check activity log for status
<cli prompt='>'>
server1> q act
server1> q damage container1
</cli>


===== TSM server config for replication (previous method) =====

On the TSM server, your are able to replicate nodes between 2 TSM server (OS independant, use full to migrate another plateform), datas and definition. You can select the data type (archive, backup, active backup...) and also which filespace you want to replicate. It's an IP replication.

It can be usefull to backup on the first TSM server, and after the replication, you can for example restore the datas directly from the second TSM server. Also useful for critical database servers with archive logs enable, which needs to be regularly backup it logs.

Here you 'll find the steps to establish a node replication between 2 TSM servers, in my case the 2 TSM are on the same machine.

On the first TSM server (TSMPROD) set parameters:
<cli prompt='>'>

                         ...........

On the second TSM server (TSMBKP) set parameters:

                         ...........
tsm: TSMBKP> quit
</cli>

Establish a server to server communication (from TSMPROD):
<cli prompt='>'>

tsm: TSMPROD> define server tsmbkp hladdress=192.168.20.7 lladdress=1600  serverpassword=admin crossdefine=yes ssl=no
tsm: TSMPROD> set replserver tsmbkp

12/06/11   15:33:09      ANR1634I Default replication server name set to TSMBKP.   

tsm: TSMPROD>q status

Now we are ready to start a node replication of one node (eco-aix61) from TSMPROD to TSMBKP:

</cli>

Now you can create an administrative schedule to daily replicate nodes.

=== Additional informations: ===

You can use **NODEGROUP** to group all nodes that requires replication:
Ex: 
<cli prompt='#'>
define NODEGROUP myreplnodes
define NODEGROUPMEMBER myreplnodes node1
upd node node1 replstate=enabled
replicate node myreplnodes
</cli>

You can check all replication commands, for example:
<cli prompt='>'>

===== Initial client replication =====

==== Method #1 ==== 

**(Node does not exist yet on Target Server.)**

Use the register/update Node commands on source server, specifying 
REPLSTATE parameter but not the REPLMODE parameter

REPLMODE automatically set to SEND on source server node

When replication first occurs, a node will be defined on the target server with 
REPLSTATE set to RECEIVE

==== Method #2 ==== 

**(Node does exist on Target Server and Import/Export has been used to import some data to the target server)**

On source server, issue update node command with REPLSTATE=ENABLED 
and REPLMODE=SYNCSEND

On target server, issue update node command with REPLSTATE=ENABLED 
and REPLMODE=SYNCRECEIVE

After first replication occurs, REPLMODE will be set to SEND on source server 
and REPLMODE will be set to RECEIVE on target server. 
===== Restart a node replication =====

A node replication process fails with the ANR0332E error.

**Symptom**

Examine the source server activity log. The following error would be logged :\\
ANR0332E Replication mode Send of node NODE1 is incompatible with mode None on server Target_server.

**Cause**

The replicated node exists on the target system and the REPLMODE=NONE option is used.

**Resolving the problem**

There are 2 ways to resolve this issue.

//Option 1:// remove NODE1 from the replication group and when replication runs it will not replicate this node.

//Option2:// remove NODE1 on target server so that when the replication runs, it will recreate the mode with proper setting. The following steps are required.
  * DELETE FILESPACE NODE1 * (on target server)
  * REMOVE NODE NODE1 (on target server)
  * Run replication. NODE1 will be recreated on target server with correct setting

===== Replication status =====

You can also use the following query which should give an empty output
  select FSNAME,TOTFILES_TO_REPLICATE,TOTFILES_REPLICATED from replicationview where TOTFILES_TO_REPLICATE<>TOTFILES_REPLATED
