Troubleshooting servicing and maintenance 8 Storage system recovery This chapter describes how to perform a system recovery To restore the HP 3PAR StoreServ File Controller system to the factory defaults see Restoring the factory image with a DVD or USB flash device page 84 System Recovery DVD The System Recovery DVD enables you to install an image or recover from a catastrophic failure At any time you may boot from the DVD and restore the server to the factory condition This enables you to recover the system if all other means to boot the server fail While the recovery process makes every attempt to preserve the existing data volumes you should have a backup of your data before recovering the system IMPORTANT data on the original OS logical drive is erased during the recovery process During system recovery you can replace the existing drives with drives of the same size or larger HP recommends that the replacement drives be the same type as the original drives but it is not required However drives in the same RAID group must all be the same type you cannot mix drive types RAID group If you replace any disk drives and then perform a system recovery you must ensure that the replacement drives do not contain a logical drive Use the Option ROM Configuration for Arrays ORCA utility to delete logical drives For more information about ORCA see the Configuring Arrays on HP Smart Array Cont

44. Shadow Copy Transport provides the ability to transport data on a Storage Area Network SAN With a storage array and a VSS aware hardware provider it is possible to create a shadow copy on one server and import it on another server This process essentially virtual transport is accomplished in a matter of minutes regardless of the size of the data A shadow copy transport can be used for a number of purposes including e backups An alternative to traditional backup to tape processes is transport of shadow copies from the production server onto a backup server where they can then be backed up to tape Like the other two alternatives this option removes backup traffic from the production server While some backup applications might be designed with the hardware provider software that enables transport others are not The administrator should determine whether or not this functionality is included in the backup application e Data mining The data in use by a particular production server is often useful to different groups or departments within an organization Rather than add additional traffic to the production server a shadow copy of the data can be made available through transport to another server The shadow copy can then be processed for different purposes without any performance impact on the original server The transport process is accomplished through a series of DISKRAID command steps File server management C
