# arraydsp -r 11270800 11271500 $ID
Performance log data is unavailable for the interval specified
arraydsp: Error in command execution
This raid array has been up and running for several months. I can't find an option for ARMserver for generating the metric data.
Where is the metric data stored? How is it gathered? Are there settings for retention of data? Etc...
Thanks!
Solved! Go to Solution.

SolutionThe following error may also appear in the /var/adm/syslog/syslog.log
file:
Nov 2 14:50:27 mims2 syslog: HP Advanced Disk Array serial number ?:
Server software logging suspended
Several events can cause the "Invalid" entries:
1. An system initialization anytime during the time period requested.
2. No data transfer during the time period requested. The performance algorithm requires at least two hours of data and looks at every
hour of data after that to compare and report performance. At least one I/O has to be logged each hour of the time period requested.
3. The ARMServer process was stopped or not logging during the time period requested.
4. Specifying invalid times when running arraydsp.
In some instances, running logprint to verify the entries in the log file will give you corrupted output (verifying that either the catalog file (LOGCATLG) or the log files is/are corrupted) - which is the reason
why arraydsp cannot list the entries for the time period specified.
This will require removal of the log files and catalog file
(see steps 1-6 below).
However, even if the LOGCATLG file appears valid, and entries in the log files are viewable, these error messages can still be received.
Perform the following steps to resolve the errors:
1. Stop ARMServer process:
/sbin/init.d/hparray stop
2. Make note of the /var/opt/hparray/log/LOGCATLG
permissions/ownership.
3. Execute the "> LOGCATLG" command to clear the file contents.
4. Restart the ARMServer process:
/sbin/init.d/hparray start
Run performance metrics when more history is available in the log files.
If there are only a few logs with invalid data, those logs should eventually
fall out of the requested time period, and valid performance data will be
available.

Re: where is the auto raid 12H metric data?
Logs are generated from ARMServer and stored under /var/opt/hparray/log.
With logprint you can look what logs were written.
See 'man ARMServer' and 'man logprint'

Re: where is the auto raid 12H metric data?
Another question, documentation regarding ARMServer and arraymond state that if it is not running that it will NOT effect I/O on a system using the array, but will executing the "/sbin/init.d/hparray stop|start" effect I/O.
The system I really need to know the metrics on is a 24x7 system
