VNX™ System Operations58 of 114 Release 7.0
Verify the daemons
After installation, daemons begin running on the Control Station at all times. If for
some reason the daemons become disabled, certain server facilities might fail.
Perform these tasks to verify whether VNX daemons are enabled:
◆ "View VNX daemons" on page 58
◆ "View HTTPD daemons" on page 58
View VNX daemons
View HTTPD daemons
It is essential that the HTTPD daemons run on the Control Station at all times, so
the Unisphere software can manage the VNX.
Action
To view the VNX daemons enabled at the Control Station, type:
$ ps -e|grep nas | awk ' { print $4 } ' | sort | uniq
Output Note
nas_boxmonitor
nas_eventcollec
nas_eventlog
nas_mcd
nas_watchdog
The complete list of daemons is displayed in the Output column of
the table. The output list for the server might be different.
If the daemons are not running, restart them by typing:
/etc/rc.d/init.d/nas stop
/etc/rc.d/init.d/nas star
Action
To view whether the HTTPD daemons are enabled at the Control Station and to reenable them if
necessary, type:
$ ps -e|grep httpd
