Check the system status
Use the nas_checkup command to perform a health checkup for the VNX.
nas_checkup runs scheduled and unscheduled health checks on the VNX and
reports problems that are found, and the actions needed to fix the problem and acts
as a system health monitor.
The scheduled run time for the nas_checkup command is every 2 weeks by default.
If a warning or error is discovered during this time, an alert is posted on the
Unisphere software.
Set up email notification for warnings or errors in the Unisphere software
Notifications page, or modify and load the sample nas_checkup event configuration
file.
nas_checkup returns one of the following exit statuses for system diagnostics:
◆ 0 — No problems found
◆ 1 — nas_checkup posted information
◆ 2 — nas_checkup discovered a warning
◆ 3 — nas_checkup discovered an error
◆ 255 — Any other error
Examples of errors that could cause a 255 exit status include, but are not limited to:
◆ If nas_checkup is run when another instance of nas_checkup is running
◆ If nas_checkup is run by someone other than root or the administrator group
(generally nasadmin)
◆ If nas_checkup is run on the standby Control Station
If a problem is discovered that requires EMC Service Personnel assistance,
nas_checkup will notify EMC.
