Adding SCSI Devices (HBA's, HP NetRAID)

Network Server Division
The best method for modifying the Marathon configuration is to
make the modifications on one IOP, save it and copy to the other
IOP.
At this point everything is ready. A final reboot of the entire array is
necessary for the disks to be redirected to the CEs.
Open Windows Explorer and examine the new drive.
Since this operation requires the installation of hardware the IOP
must be brought down. Once again the decision must be made to
bring down the whole array for a period of time and forgo any re-
mirroring operations or bring down the IOPs one at a time and suffer
the re-mirror operations.
When adding SCSI devices care must be taken not to affect the
present 4 digit SCSI ID settings of the existing devices. Adding a
SCSI device in a higher order on the SCSI bus scan will cause lower
order devices to shift the 4 digit SCSI ID settings. If this occurs the
Marathon Configuration will be corrupt and will have to be
recreated.
It is not necessary to install duplicate devices in both IOPs unless
those devices will be used to control mirrored disks, as in the case of
a NetRAID controller. It is okay to add an HBA for backup
purposes without adding a matching one in the other IOP. Once
again, care should be taken to ensure all existing mirrored device 4
digit SCSI IDs are not affected by the addition of the device.
