MultiVantage Application Resets

Single-Process Restart

The system automatically performs these restarts logs them in the ECS

logger. Occurrences of single-process restarts can be viewed applying

"tail" or "grep" to the log file from Linux command line.

When the system is powered up, or when it experiences a catastrophic fault that

interrupts its basic functions, it undergoes a reboot. In addition to reboot, there

are several less severe resets available for the system to recover from less

disrupting errors. The technician can also initiate these resets with a command.

Multivantage application resets can have wide-ranging disruptive effects.

Unless you are familiar with resetting the system, follow normal escalation

procedures before attempting a demand reset.

If a reset fails to recover normal system operation, the firmware that controls

reset will escalate to the next higher level, up to reboot if necessary. Hot

restarts are not supported for S8700 Multi-Connect servers. An on-demand,

planned, or scheduled interchange results in a warm restart of the standby

server if it is in a refreshed state, or a reboot if it is not refreshed.

When a reset occurs (including an interchange), an error is logged against the

SYSTEM maintenance object (MO). The error code gives information about the

cause of the reset. Information about the reset is also logged in the initcauses

''display initcauses'' on page

EPNs can also undergo individual resets. These are described in:

''reset ipserver-interface'' on page 7-260

''EXP-INTF (Expansion Interface Circuit Pack)'' on page 8-762

''EXP-PN (Expansion Port Network)'' on page 8-821

For EPNs in high- and critical-reliability systems, IPSIs can also undergo

interchanges. These are described in:

''IPSV-CTL (Ipserver Interface Control)'' on page 8-950

For critical-reliability systems, PNC interchanges are described under

(PNC Duplication)'' on page
