| Chapter 6 Backing Up and Restoring |
Some sophisticated disk devices contain hardware functions to copy disk data within the disk units or to other disk units. For example, Fujitsu Storage Systems ETERNUS provide the Advanced Copy function and EMC's Symmetrix storage systems provide copy functions such as TimeFinder and SRDF.
This section describes the procedures for backing up and restoring object configurations and data of local disks and shared disks through use of these disk units' copy functions.
Backup and restore can be performed on any of the following nodes.
Nodes that operate services
Nodes that belong to the same cluster domains as those of nodes operating services
Nodes that do not belong to the same cluster domains as those of nodes operating services
In the following subsections, physical disks named c1t1d1 and c2t1d1 are registered with a shared class named Class1 and mirrored, and a mirror volume named Volume1 is used for services.
