Backup/Recovery Guide for HP
Assured Availability Systems
While HP Assured Availability Systems provide very high level of server availability, HP
recommends that backups be done at first install, at upgrade times, and periodically to
preserve data in the event of disasters. This guide provides important information to help
system administrators configure and setup the system for backup.

Backup topologies and tradeoffs
There are many backup topologies one might consider for backing up HP AA systems.
To help system administrators configure and setup backups HP recommends three
topologies.
CE boot disk
IOP boot disk
data disks
The first topology is a pure-local backup configuration (see figure 1). This configuration uses
a HP SureStore TapeRack with two DLT80r and two DLT40r tape drives. The two DLT80r
tape drives are configured using the Marathon Configuration Utility to be "owned" by the
CEs – each DLT80r act as independent tape drives in the CE. Backup software, such as
Veritas Backup Exec 7.3 or Computer Associates ArcServe IT 6.61, is installed on the CE

In fact, it is possible to have just a single tape drive. Again, since both built-in SCSI channels in the IOPs are used in the standard configurations, an additional SCSI HBA must be added to each of the IOP’s for the tape device and to maintain the hardware redundancy configuration. 12/08/99 Hewlett-Packard Co.

Reboot the selected IOP to MARATHON OFFLINE MODE (the server already is down/cannot be rebooted - or you would repair it from the running CE OS). Replace the driver or delete the service - or otherwise make repairs to the CE BOOT device. 12/08/99 Hewlett-Packard Co. - Page 11 In the normal HPAA system, it is recommended that the System Administrator keep a spare good copy of the CE boot drives on a 200MB or larger partition. This can be an insurance policy for a system recovery. 12/08/99 Hewlett-Packard Co.
