Backup Confiurguration Setup Notes

Pure-local backup configuration

Semi-local backup configuration

6-6
The following are some important recommendations when setting up
each of the different backup configurations. Additional information
on SCSI IDs and settings can be found in Chapter One of this guide
or in the AA 4000 Installation Guide.
•
The DAT and DLT tape drives can share the same SCSI channel.
NOTE
The SCSI ID of each device must be set properly.
•
CEs own the DLT tape drives; each IOP owns the DAT drive
that is directly attached.
•
Follow the Marathon SCSI configuration rules in the AA 4000
Installation Guide. Non-shared SCSI devices must use SCSI IDs
that are used on only one of the IOP (e.g. if a DLT drive has
SCSI ID 4 on a SCSI channel, the matching SCSI channel on the
other IOP must not have a SCSI device with ID of 4). For
simplicity, it is best to configure each tape devices in the tape
rack with a unique SCSI IDs (e.g. 2, 3, 4, and 5).
•
Backup software should be properly installed on the CE and both
IOPs. The three instances of backup software run independently.
•
Using Veritas Backup Exec 7.3 in this configuration will give a
"Storage device configuration error"on the IOP. This is the result
of the DLT 7000 being configured in the CE but not available to
the IOP. This is okay because the Marathon Configuration
Manager has taken away the usage of the DLT 7000 for use in
the CE.
•
The DLT tape drives are owned by CEs.
NOTE
The tape drives are not mirrored devices but are unique SCSI
devices; the Marathon SW does not write the same data to the
tape drives as it does for disks.
•
SCSI ID of DLT drives must be configured according to
Marathon SCSI configuration rules.
•
CE backup software backs up all disks, CE's and IOP's, in a
HPAA system.
•
The Virtual network connection between CE and IOPs must be
set up properly. The CE must be configured to see each IOP
server through the internal virtual link as in the standard HP AA
system set up.
