Array Logs 209
Array Logs
The array continually monitors and records information reflecting the current
operating state of the array. This information is stored by the array in its
internal memory. The Command View SDM software reads this information
and stores it in log database files on the host. An overview of array log
management is shown in Figure 5.
There are three types of log files:
■ Controller (Device) Logs - All internal array actions or events are monitored
by the controller and saved as event messages in the array’s internal
memory. The Command View SDM software periodically polls (every 15
minutes, the default) the array and stores these events as entries in the
controller log database file.
■ Usage (State) Logs - Command View SDM periodically (every 24 hours by
default) runs the armdsp -a command to obtain the current state
configuration of the array. It copies the output of this command into the
usage log file.
■ Software logs - contains entries indicating when the controller event log
poller has run and how many entries were collected.
Log files are stored in a directory structure that identifies the file by date and
file type. See "About Log Files" on page 219.
