As we are running an application on cluster 1 . And cluster 2 is for database oracle server.If one of clusters down it will failover another one. As we are having a problem everytime we shut down cluster 2, bring it up and then bring a cluster 1 up . When Cluster 1 is up and running .Cluster 2 is then failed and all group moved to cluster 1. We thought a problem could be caused by a fibre channel but checked it and it was OK ...Any suggestions could be appreciated ...Thanks,

Problem bring up a cluster group after reboot.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
