A panic is a severe event as it halts a system during its normal operation. A panic
message from the kernel module or from a device driver indicates a hardware problem or
software inconsistency so severe that the system cannot continue. The operating system
may also provide a dump of the CPU register contents and a stack trace to aid in
identifying the cause of the panic. The following is an example of such a message:
VxVM vxio PANIC V-5-0-239 Object association depth overflow
• FATAL ERROR
A fatal error message from a configuration daemon, such as vxconfigd, indicates a severe
problem with the operation of VxVM that prevents it from running. The following is an
example of such a message:
VxVM vxconfigd FATAL ERROR V-5-0-591 Disk group bootdg:

• NOTICE
A notice message indicates that an error has occurred that should be monitored. Shutting
down the system is unnecessary, although you may need to take action to remedy the fault
at a later date. The following is an example of such a message:
VxVM vxio NOTICE V-5-0-252 read error on object subdisk of mirror plex in
volume volume (start offset, length length) corrected.
• INFO
An informational message does not indicate an error, and requires no action.The unique
message number consists of an alpha-numeric string that begins with the letter "V". For
example, in the message number, V-5-1-3141, "V" indicates that this is a VERITAS
product error message, the first numeric field (5) encodes the product (in this case,
