9.2.5.1 OVERVIEW
The disk reconfiguration tools are made up of shell scripts, VTOCs, RCV keystroke files, data/information files, and
``C'' object files. Usually the disk reconfiguration tools are implemented as shell scripts. However, in some cases it
is much easier, and more efficient, to use a ``C'' program. Disk reconfiguration scripts (tools) that are normally
called directly from a terminal are referred to as first-level scripts. Second-level scripts (tools) are normally called
from first-level scripts instead of a terminal. The keystroke files are used to modify and evolve the ECD and SG data
bases for the new disk configuration.
Table 9-4 gives the contents of the disk configuration tools for the current software releases.

9.2.5.2 Clear Off-Line Superblock (COFLSB)
All file system (FS) partitions that grow in size or move on the disk must have their superblocks rebuilt according to
the new disk layout. Since the
UNIX
®
operating system provides no tool for the off-line disk, one had to be written.
The COFLSB program is used to attach to a partition on off-line disk and to clear the partition's superblock. The
COFLSB provides a mount off-line partition (MOP) type of interface to the invoking script that allows it to read or
write the off-line partition for a maximum period of 4 hours. When the invoking script is done accessing the off-line
partitions, it kills the COFLSB process. When COFLSB terminates normally (due to a time-out or a kill command), it
unmounts the off-line partition. If COFLSB is aborted due to a system recovery (51 or higher), the off-line partition
may not be unmounted and may remain in the mount table. This condition can only be cleared by calling COFLSB to
remount the partition and then killing COFLSB. The RMVOFLMNTS script will remove a hung-mount table entry
caused by an abnormal COFLSB termination.
The RMVOFLMNTS script performs the following operations when it finds a hung-mount table entry due to an
abnormal COFLSB termination:
Determines which off-line partition has the hung-mount point
Calls COFLSB to remount the off-line partition
Kills the COFLSB process.
The RMVOFLMNTS script is called at the beginning of the COPYODDOFL and MISCOFLINIT scripts before they
use COFLSB to mount an off-line partition. It can also be called directly by entering the following message at the
master control center (MCC) video terminal:
EXC:ENVIR:UPROC,FN="/updtmp/site/rmvoflmnts",ARGS="MCC";
Response:
RMVOFLMNTS COMPLETED.
