Rebooting The System; Monitoring The System After A System Panic - HP 9000 V-Class Operator's Manual

Rebooting the system

Once you have corrected any problem, you are ready to reset and reboot
your system.
Step 1. Reset the V-Class node using one of four different methods:
• Power cycle the V-Class node by turning the keyswitch to the DC OFF
position then back to the On position. See "Key switch panel" on
page 15 for more information.
• Press the keyswitch panel TOC button.
• Type reset into console window (if in menu or fourth mode only).
• do_reset executed from one of the teststation tsh windows.
There may be differences in the boot up displays/activities as compared
with your normal boot up sequence.
The system may have saved a system core file to disk. See "Abnormal
system shutdowns" on page 79.
Step 2. If the system panicked due to a corrupted file system, fsck will report the
errors and any corrections it makes. If fsck terminates and requests to be
run manually, refer to the Managing Systems and Workgroups for
further instructions. If the problems were associated with your root file
system, fsck will ask you to reboot your system when it finishes. Use the
command:
reboot -n
The -n option tells reboot not to sync the file system before rebooting.
Since fsck has made all the corrections on disk, you do not want to undo
the changes by writing over them with the still corrupt memory buffers.

Monitoring the system after a system panic

If the system successfully reboots, there is a good chance that you can
resume normal operations. Many system panics are isolated events,
unlikely to reoccur.
