Using Serviceguard Extension for RAC, 10th Edition, April 2013

RAC MNP packages are required to define a 'same node up' package dependency on the OC
MNP, since Oracle Clusterware must be running before any RAC database instances can be
started. When using ASM for storage management, the ASM DG MNP must have a package
dependency on the OC MNP and the corresponding RAC MNP packages must have a "same
node up" dependency on the ASM DG MNP.
In SGeRAC, the Oracle Clusterware storage (Oracle Cluster Registry and voting disk) can be
configured as:
• Raw logical volumes managed by Shared Logical Volume Manager (SLVM) or Cluster Volume
Manager (CVM)
• Files managed by Cluster File System (CFS)
• Oracle Automatic Storage management (ASM) Disk Groups (from Oracle 11g R2). The
members of the ASM Disk Groups can be either shared raw logical volumes managed by
SLVM (ASM over SLVM) or HP-UX raw disks ( ASM over HP-UX raw disks)
In SGeRAC, the RAC database files can be configured as:
• Raw logical volumes managed by Shared Logical Volume Manager (SLVM) or Cluster Volume
Manager (CVM)
• Files managed by Cluster File System (CFS)
• Oracle Automatic Storage management (ASM) Disk Groups (from Oracle 11g R2). The
members of the ASM Disk Groups can be either shared raw logical volumes managed by
SLVM (ASM over SLVM) or HP-UX raw disks ( ASM over HP-UX raw disks)

The SLVM Volume group used for Oracle Clusterware storage are configured in the OC-MNP
package. The SLVM Volume group used for RAC database storage are configured in the RAC-MNP
package.
