set tone-clock
Use set tone-clock to set the active tone/clock for a PN that has a duplicated
tone/clock circuit pack. Reset the default active tone clock in each PN after using
set tone-clock. If it is not in use, a single failure can cause an unnecessary
service outage. The schedule maintenance tone-clock switch option does not
reset the tone-clock to the default active if it was not active at the beginning of the
test.
set vector
Use set vector to specifies restart levels for core dumps and places core dumps
on primary Mass Storage System (a tape in a tape system and core dump
memory cards in a memory card system) devices for later examination. The set
vector command allows technicians to tailor restart levels that copy memory to
primary Mass Storage System devices.
NOTE:
Software never requests an extended reboot.
To force an immediate core dump, set the appropriate bit using this command,
then enter reset system at a level that forces core dumps corresponding to set
vector bits.
When a system restart occurs in a simplex system with the corresponding vector
bit set, the core dump writes to secondary storage (the primary MSS device).
Once the core dump writes, the vector clears and the restart executes.
!
WARNING:
This command disrupts service in a simplex system.
The active SPE executes a core dump when:
■
A system restart occurs on the active SPE with the corresponding vector bit
set.
■
The active SPE-active option is selected when the vector bit is set.
■
The SPE-standby option is selected when the vector bit is set.
■
The active SPE-maint option is selected when the vector bit is set.
