Recovering from failures

This chapter provides detailed information on recovering from HP-UX

Performance problems are generally characterized by:
• The system responds to one or more programs/users but not all, or
sluggishly to others
• The system seems to be very slow
System interruptions usually result in a total loss of CPU resources for
all users/programs due to a:
• System hang
• System panic
• HPMC
