(NonStop Himalaya S-Series Servers)
Before performing a Copy Memory: Tape task, be sure to load a write-enabled
cartridge tape in the tape drive and bring the drive online.
Using a 5190 or 5194 Drive for a Memory Dump (NonStop
Himalaya S-Series Servers)
You can perform a memory dump to disk while a processor is running. However, if a
processor is down, you can dump memory only to tape. All processors in the system
must be halted before performing a memory dump to tape.
If you need to dump a processor’s memory to tape, you must perform one of the
following tasks:
•
Halt all processors and perform a memory dump as described in the Himalaya
S-Series Operations Guide. You can perform a memory dump in the TSM
Processor Status dialog box in the TSM Low-Level Link Application.
•
Dump the processor to disk as described in the Himalaya S-Series Operations
Guide. Use the BACKUP utility to copy the dump to tape. See the Guardian Disk
and Tape Utilities Reference Manual for information about the BACKUP utility.
For instructions on how to dump an entire system, how to make a compressed disk
copy of a memory dump file, and how to submit a memory dump to your service
provider, refer to the Himalaya S-Series Operations Guide.
Using a 5190 or 5194 Drive for a Tape Load (NonStop Himalaya
K-Series Servers)
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.
If you want to perform a tape load with a 5190 or 5194 tape drive, verify the following
information for the system you are using.
NonStop Himalaya K2, K100, K200, K1000, K1000SE, K2000,
and K2000SE Server Tape Loads
Using the system control panel (SCP) 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 tape drive is connected to
Caution. Performing a memory dump to tape on a running system can result in disk
corruption.
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.
