(NonStop Himalaya S-Series Servers)
MFC 0 or 1 in the base system cabinet (cabinet 1). When you perform a tape load, the
tape drives cannot be attached to a 3216 controller.

Server Tape Loads
Using the Remote Maintenance Interface (RMI) terminal to load the system image from
the system image tape (SIT) is referred to as a tape load. If you want to use a 5190 or
5194 tape drive attached to an MFC as the tape load device, verify that:
•
The MFC is installed in an MF-8 I/O cabinet configured with processors 0 and 1
(using the same processor pair as $SYSTEM).
•
$SYSTEM is configured on a pair of 42xx disk drives in the same MF-8 I/O cabinet
with the MFC.
•
$SYSTEM disks are attached to the same MFC that the tape drive is attached to.
•
The MFC and tape drive are properly configured in the system configuration file.
Using a 5190 or 5194 Drive for a Tape Load (NonStop Himalaya
S-Series Servers)
You cannot load the system from a tape drive that is connected to a 6760 adapter. You
must use a tape drive that is connected to the SCSI port of a PMF CRU in group 01.
If your system disk becomes corrupted and you are unable to load the system from a
disk image, you may bring up the system by performing a tape load from the system
image tape (SIT); a tape load will restore the system image files to the $SYSTEM disk.
Then you restore from your most recent system backup those files that are not on the
SIT.
Refer to the Himalaya S-Series Operations Guide for alternative system disk recovery
options.
Caution. Compaq recommends that you perform a tape load only after consulting with your
service provider and attempting other system disk recovery options. Tape load is a destructive
function that destroys the files on the system disk. It is an emergency method for starting the
system when no operating system image is available on disk.
