Array Controller Logs
Types of Array Controller Logs
There are two types of array controller logs:
■
Controller logs. Controller logs contain events relating to the operation of
all FRUs in the array, obtained from the controller during the operation of
the array. The CommandView SDM logging routine polls the array every
15 minutes to retrieve and store the log entries in special controller log files.
Each log entry has a decimal event number and an event name. A list of
the “Controller Log Event Code Descriptions” is available at:

■
Usage logs . Entries for the usage log are created using the output of the
armdsp -a
command. The CommandView SDM logging routine runs
the command and stores its output as entries in the usage log file. This
occurs every 24 hours by default, but can be changed to a setting from 1 to
100 hours.
Location of Array Controller Logs
Array controller logs are stored in three locations:
■
NVSDRAM . 256 kilobytes of NVSDRAM memory is reserved to hold one
thousand log entries.
■
Image Disks . The logs in NVSDRAM are mirrored and backed up by the
image disks.
■
Host OS directory . Polls the controller every 10 minutes and updates the
following host directory, located on the host internal disk:
<command view home dir>/sanmgr/cmdview/server/logs
