Replacing the Disk Bootstrap Program on a
Nonmirrored Volume (NonStop S-Series Servers)
Replacing the Disk Bootstrap Program on a Nonmirrored
Volume (NonStop S-Series Servers)
This procedure replaces the disk bootstrap program on an unmirrored volume of a
NonStop S-series server.
The REPLACEBOOT attribute does not apply to Integrity NonStop NS-series servers.
Instead, the bootstrap program is installed through firmware update into flash memory.
1. Review information about the REPLACEBOOT attribute on page 14-71.
2. As a safety measure, use BACKUP VOLUME MODE to create a backup tape of
the disk on which you are replacing the bootstrap program.
3. Replace the bootstrap program on disk $DATA01:
-> CONTROL DISK $DATA01, REPLACEBOOT $SYSTEM.SYSnn.SYSDISC
4. Reset and start the disk:
-> RESET $DATA01
-> START $DATA01
Caution. This procedure assumes that the nonmirrored disk is not a system disk. Do not,
under any circumstances, attempt to replace the disk bootstrap program on a system disk that
is not mirrored. If you attempt to do this and the CONTROL DISK, REPLACEBOOT operation
fails or if the bootstrap program is unusable and no other system disk exists, contact your
service provider and refer to the information about restoring a system disk in the NonStop
S-Series Operations Guide.
