Event-Message Text
\ system . manager : ERROR *0012* Unable to create backup
&& Process, PROCESS_CREATE_ Error error : detail
What Happens
The primary name manager process retries to create a backup process unless the
PROCESS_CREATE_ failure indicates that the backup CPU is down. If the backup
CPU is down, an attempt is made to create a new backup 30 seconds after receipt of a
CPU UP system message for the backup CPU.
For errors other than CPU DOWN, the primary name manager pauses for 30 seconds,
and then tries again to create a backup; if this second attempt fails, the next attempt
occurs after a 60-second delay. This process continues, the delay increasing by 30
seconds at each failure, until the delay reaches five minutes. Thereafter, the primary
name manager attempts to create a new backup every five minutes.
The primary name manager only issues this message if its initial attempt to create a
backup fails; unsuccessful retries are not reported.
