HP StorageWorks XP Cluster Extension Software Installation Guide (T1656-96034, April 2010)

1. On the P-VOL side (local data center), create the volume groups, logical volumes, and file systems
that will be used with the Linux clusters.
2. Use the XP RAID Manager horctakeover command to switch the XP RAID Manager device
groups from site A to site B. This allows nodes in the remote data center to access the shared
disks with read/write access.
3. Create mount points on each node in the remote data center, and then use vgscan to import
volume groups and logical volumes.
4. Make sure that the volume groups are not activated automatically at system boot time.
NOTE:
For more information about using LVM, see your Linux cluster software documentation.
Installing and configuring the cluster software
Install and configure the cluster software for your Linux operating system. See the SLE HA and RHCS
documentation for detailed installation procedures.
NOTE:
A properly configured and fully functioning cluster solution is a prerequisite for the XP Cluster Extension
Software.
