Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy for Linux B.01.00.00, July 2013

where:
• <domain_name> is the name of the domain to which the new user will belong. If you are
using domains, specify the name of an existing domain in your system. Specify 'all' as
the domain name if you are not using any domain.
NOTE: For Metrocluster operations the user must have the “edit” privileges. HP strongly
recommends you to create Remote Copy volume groups and user with “edit” privileges for
the Metrocluster operations under a 3PAR storage system domain. However, Metrocluster
does not restrict you to configure a user with “super” access privileges for Metrocluster
operations who has access to all the domains.
Setting up password files for cluster nodes to connect to HP 3PAR storage systems
Password files must be configured for Metrocluster to communicate with the HP 3PAR storage
systems. These password files must be generated manually on all the nodes.
If you want to configure password files from the cluster nodes to the storage systems using the utility
setup MC3PARpasswdfile, then run the utility on all the nodes using an appropriate 3PAR user on
the corresponding 3PAR storage system as follows:
# $SGSBIN/3parrc/setupMC3PARpasswdfile <user_name> <storage_system_name
or IP or DNS name>
When prompted, enter the username and password for the respective users on the corresponding
storage systems that are passed as arguments.
For example,
# $SGSBIN/3parrc/setupMC3PARpasswdfile mc3parusr 3par001
Metrocluster 3PAR password file creation utility....
The user name specified is mc3parusr
The storage array specified is 3par001
Enter the username once more and the password when prompted

Configuring LVM volume group
LVM storage can be used in the disaster recovery clusters. The following section shows how to set
up the LVM volume group. Before you create volume groups, you must enable activation protection
for logical volume groups, preventing the volume group from being activated by more than one
node at the same time. For more information on enabling activation protection for logical volume
groups, see Managing HP Serviceguard A.11.20.10 for Linux available at http://www.hp.com/
go/linux-serviceguard-docs.
Creating LVM volume groups
To create volume groups, do the following:
1. Create LVM physical volumes on each LUN.
For Example:
