Creating the data and SRL volumes on the primary site


Creating the data and SRL volumes on the primary site
Prev	Setting up replication on the primary site using VVR	Next

Create the data volume if you do not have one already.

The data volume on the secondary site has the same name and the same size as the data volume on the primary site.
The data volume and Storage Replicator Log (SRL) volume should exist in the same disk group.
Mirror the data volume in the absence of hardware-based mirroring.

To create the data volume on the primary site

In the disk group created for the database, create a data volume for the data on primary site. In the examples below, the dbdata_vol volume on the primary site is 12 GB:
```
# vxassist -g dbdatadg make dbdata_vol 12000M disk1 disk2
	
```

Create the SRL. The SRL is a volume in the Replicated Volume Group (RVG). The RVG also holds the data volumes for replication.

The SRL on the secondary site has the same name and the same size as the SRL on the primary site.
You must create SRLs on disks without other volumes.
Mirror SRLs and in the absence of hardware-based mirroring.

In the example procedure below, dbdatadg is the disk group and dbdatavol is the data volume to be replicated.

To create the SRL volume on the primary site

On the primary site, determine the size of the SRL volume based on the configuration and amount of use.
See the Storage Foundation and High Availability Solutions Replication Administrator's Guide for details.
Issue the following command:
```
# vxassist -g dbdatadg make dbdata_srl 6800M disk4	disk5
```
Note:

Assume that for the example setup that disk4 and disk5 are already added and are part of the same disk group. They are used in this step for mirroring and creation of the SRL.
If the SRL volume is not already started, start the SRL volume by starting all volumes in the disk group:
```
# vxvol -g dbdatadg startall
```
