4. Copy the files listed in /keyfiles into a file system on the second disk.
This procedure assumes the file system is named /n.
cpio -pdaumv /n < /keyfiles
5. Move /keyfiles to the second disk.
mv /keyfiles /n
You now have a copy of the key Un i x files on the second disk. To find out
how to recover from a crash by booting from this copy, see Section 4.5.4.
4.5 Crash Recovery
Depending on the cause, a system crash can leave an IRIS workstation in a
state that requires some software repair. This section describes the steps you
should take immediately after a workstation crash and the procedures for
repairing the disk if the software is damaged.
See Appendix B for a list of system error messages and their probable causes.
Also, see the crash(8) manual entry.
If the IRIS workstation stops running for some reason, follow this recovery
sequence:
1. Try to reboot the workstation by entering the reboot command:
reboot
2. If the system does not respond, wait one minute, and press the
Reset
button.
The system should attempt to follow the normal boot sequence (see
the description of init, below).
3. Boot the system in single-user mode.
4. Run the file system check program, fsck. This program may identify
problems with the file system (see Section 3.3 and fsck in the Un i x
Programmer’s Manual, Volume II).
5. If fsck runs without any problems, enter multi user mode:
multi
If rebooting and running fsck does not solve the problem, see the procedures
below for identifying the problem and recovering the system.
