Creating a WPAR root on local disk
Use the following procedure to create a WPAR root on the local disk on each node in the cluster.
To create a WPAR root on local disks on each node in the cluster
- Create the actual WPAR root directory.
- Use the mkwpar command to create the WPAR.
mkwpar -n wpar -h host -N ip_info -d wroot -o /tmp/wpar.log
Use the following information to replace the appropriate variables:
wpar
The name of the WPAR.
host
The hostname for the WPAR being created.
ip_info
The information to set the virtual IP address of the system to be the IP address of the WPAR. This value also defines the device name for the NIC associated with the IP address.
If you do not specify the value of the interface or netmask, the global partition's values are used.
Use the following format to replace ip_info:
interface=interface netmask=netmask address=IPaddress
Example: interface='en0' address='172.16.0.0' netmask='255.255.255.0'
wroot
The location of the WPAR root directory. For example: /wpar1.
To install application for DB2 under WPAR, you may want to create a detached WPAR where
/opt
and/usr
are writable under WPAR. An example on how to create detach WPAR:# mkwpar -l -n db2wpar -h db2wpar -d /wpars/shirish -r -N \ address=10.209.87.132 netmask=255.255.252.0
- Repeat the command in step 2 to create the WPAR on each system in the service group's SystemList.
- Start the WPAR.
- On one of the systems in the SystemList, mount the shared file system containing the application data.
