NAS System Time is Wrong
Workaround
Use the process in DSFS that collects information regarding
various matrices in the system.
•
Status fields (overall state, service status, servers status)—
Information is been collected every 40 seconds.
•
Capacity—Information is collected every 1800 seconds.
•
Current performance (NFS, CIFS, Replication, NDMP, Network)
—Information is collected every 40 seconds.
•
Recent performance (the graph)—Information is collected every
60 seconds.
•
Load balancing (CPU, number of connections)—Information is
collected every 40 seconds.
Description
Scheduled tasks are running in wrong times. The date/time of
event log messages is wrong.
Cause
•
The time on the NAS system is incorrect.
•
No NTP server is defined for the NAS system.
•
The NTP server servicing the PowerVault NX3500 is either down
or has stopped providing NTP services.
•
There are network problems communicating with the NTP server.
Workaround
1
Identify the NAS NTP server from the
System Configuration/
Time Configuration
page. Record the host name(s) or IP
address(es) for further reference.
2
If no NTP server is defined, define one. It is recommended
synchronizing the NAS system clock with the NTP server used by
the Active Directory Domain Controller (ADDC). This avoids
time difference issues and possible authentication problems. In
many cases the ADDC is also the NTP server.
3
Verify that the NTP server is up and provides the NTP service.
4
Check the network path between the NAS system and the NTP
server, using ping for example. Verify that the response time is in
the millisecond range.
